Diary - Part Ten–C
January 2025 – March 2025
Linas Vepštas
Abstract
Unlike parts one through nine in this series, this one is not really about the language–learning effort. It is instead a private diary; a continuation of Part Ten–B, which got over–long. It is not curated for human consumption; I am making the assumption that no human being will ever actually read this. Thus, its filled with random–stuff I feel like writing. Some of it is very personal, some of it is nonsense. Mostly, I am finding that the act of writing helps otherwise vague and scattered thoughts quantum–collapse into a more coherent form, where I can examine them, like a dead butterfly pinned down in a display case. Dead words.
Human readers are discouraged from reading this, on the grounds that there are probably better uses of your time, than to sync your thought–patterns onto mine own. Live your life.
Introduction
Part Ten already got an introduction. How many more do you want?
29 December 2024
It’s a good time to start afresh. In short – dafuq am I doing? I seem to be going at max RPM in first gear. Is this supposed to be fun? I’m burning out writing the Atomese sensori-motor code. In the previous diary entry, I convinced myself that this was not a totally stupid idea. Now, I am not so sure.
One of the early visions for Atomese was to create affordances suitable for algorithmic boostrapping. This is a nice vision, but perhaps a mistake – and on multiple levels, a mistake. Perhaps I got lost in the details. The details are a vision of computing from 100 years ago: that lambda calculus can say anything sayable. Updated to more modern time, we find that lambda calculs is the internal language of Cartesian Closed Categories. These are big words, and the bigness of them is beguiling, and I think lie at the heart of the mistake.
Thanks to my physics/math background, it was very natural for me to dive deeply into the microscopic details of structural atoms. Perhaps one of my finest acheivements is coming to an understanding that jigsaw pieces are perhaps an ideal structural element. Jigsaw can be used to build anything. They are more naturally expressive than lambdas, and have natural identification with tensors (and the many-world parallelisms of tensors). Making them ideal for Bayesian priors, and other many-choice settings. They have natural interpretation as graphs. But they’re typed, and so carry significant information (having significant information content.) And I didn’t invent them. Many other have invented and reinvented them, over the decades. So, all around goodness. So why am I crying?
Well, if the goal is to build AGI ... well, if jigsaws are like atoms (like literally, cehmical atoms) I’m daydreaming of creating biology from them. Well, that’s nuts: biomolecules have millios of atoms (daltons, or whatever). I’m not gonna get there. I might discover some cute low-level assemblies. But that’s it. Not scalable.
OK, second example. It’s like day-dreaming of building a computer from individual transistors. Of course, this has been done, but it took decades and tens of thousands of engineers. There’s pretty much exactly zero infrastructure for working with jigsaws. Like just about none at all. So I’m at square one. No one is interested, no one is helping. Basically, it won’t happen.
OK, third example. It’s like day-dreaming of building a neural net out of individual neurons. Oh wait ... well, again, this has happened. Again, this took decades and tens of thousands of academics, grad students, engineers, tinkerers of all kinds. So, yes, neural nets all start with a single sum and a single sigmoid, but the scaling is the result of a massive engineering effort.
I think jigsaws are as promising as any of these things, as a basic, basal, low-level self-assembling structural component. Its just that ... I’m at square one, and no one shares my vision. So its not going anywhere.
What to do? Well, the lesson to be taken from LLM’s or, perhaps, Microsoft Copilot, is that the world is filled with human affordances. At this stage, in the early 21st century, it is easier to build neural nets that can work with the available human affordances, such as coding in java or python or whatever, than it is to create this assembly-like intermediate language I call “Atomese”. Atomese was meant to make it esy for machines. But it starts at such a low level, that leveraging up seems single-handedly impossible. Just teach the computer to code in python, and be done with it.
Hah. And there’s the rub. Current state of the art in neural nets suggests that they’ll never be able to arrive at the abstractions needed for doing the kind of reification that humans natrually do. So licking back and waiting for AI to magically learn how to program seems ... well, it renders me into an observer, rather than participant. I’d rather participate, for now.
So what can I grasp at, what can I do, to be effective? Well, I’ve got several more visions. I articulated them on the opencog wiki in the last few days, and also in a readme file somewhere. But again – they’re visions, and from what I can tell, visions shared by no one, so I’m like – roll up your sleeves, and get to work, you dog. This leads to a feeling of hopelessness. I burn out from going max RPM in first gear.
What should I do instead? When I ask this question explicitly, I rapidly get to the general perception of well, I can rattle off all the social, psychological, cultural, political, economic activities that humans engage in, and they are so varied. Somehow, being a medical doctor is worthier than sitting around doing cross-words all day. or being a junkie. Western culture got that part right. But perhaps medical doctors burn out: there’s always one more patient to treat. So, me here: there’s always one more technical paper to read, one more line of code to write. Max RPM in first gear.
The current Western-civ definition of shifting into higher gear is to garner money, power, fame, influence. Gaining any of those takes effort and talent, and like any human activities, take decades to hone one’s skills. And as that is done, I read less papers. Perhaps this should be like atheltics: don’t overtrain one muscle group, while leaving others atrophied? I’ve let my power, fame, money and influence atrophy. And now here I am, wimpering like the old man that I am, that my ethereal being hurts. The physical therapist suggests some simple exercises for the weak and dibilitated: pay the bills, read the email. Like any ordinary person recuperating frome an injury, taking the doctors advice is hard. I don’t want to go out and exercise, to go out and exercise and gain the strength so I can go to the olympics of wealth, fame and power. Unh, unh. Cause people do what they want to do, and I am a person. Perhaps whats-hisname from Star Wars could say “force yourself”, but well, dafuq. I can force myself to ride a bike up that hill in Southern Walnut Creek bike trail. I can force myself to do what it takes to win gold medals at the US masters nationals. I do NOT have to force myself to read textbooks on general relativity or string theory, because I find that actuall fun. I do have to force myself to pay the blls and read the emails, cause that’s not fun. Or something.
I feel like I am procrastinating. And, well, I am. Because the duties that I shirk do not provide the dopamine reward that I’ve grown accustomed to. I’m a goddamn dope addict, addicted to reading math textbooks, instead of doing whatever the fuck I should be doing. Crap.
Worse: I engage in activities without asessing the worthiness of those activites. Like I spent a month hacking on the 25th anniversary edition of Bigfoot. (the i370 code base.) Its useless, cause no one but no one except maybe Paul Edwards, and even then that;s a maybe ... no one will ever use it and no one will ever care. I might as well have spent the month doing crossword puzzles, or mainlining heroin, or something.
There was one minor utility: in the back of my mind, I got to review the landscape of operating system technology, from assemblers and compilers to kernels, and file systems and containers. It lead to my playing with Ceph, so now I’ve got my home cloud. And its interesting to see how Ceph is multi-machine autonomous in a way that single-machine OS’es are not.
Which brings me back to where I started: my current path of tinkering with Atomese is not going to recreate Ceph in my lifetime. So I’m torn. One part of me rests completely assured that million-dimensional vectors of jigsaws are absolutely the correct approach. Another part of me is repelled by the daunting task of taking the next steps. Or mis-steps, as they may be. A third part of me laments my wasted youth. A fourth part of me is more than happy to also waste my waning years. A fifth part of me is deluded into thinking that perhaps by verbalizing into this diary, something will happen.
But is 10PM Sunday night, and I’m tired. I think I will go do something relaxing. I think I will got read more of David Tong’s Cosmology. It’s a nice treatment. I’d never really seen a decent treatment of FLRW before. It’s not super-complex; the lectures are aimed at undergrads. But they’re focused, concise, clear, well-written. Unlike a lot of crap I read. Why can’t people write? I wonder if I can write. I think I can, but no one reads what i write, so maybe my topics, my style, the things I have to say just aren’t, well, they’re just not Kardashian enough.
With that, good night, adieu.
30 Dec 2024
The Big Think. Somehow, for decades, longer, since college, before, I’ve avoided actually thinking about the ”big question”: what is AGI, really? I’m going to avoid it a bit more, with a few paragraphs of autobiography.
I remember the first time I built something. I stacked two blocks, one on top of another, and they didn’t fall down. I got to three even, but could not move past that. Mother had gone shopping, I guess, and left my sister and I in the basement. The basement was kind of a safe space: nothing there, no way to escape, nothing to break, no way to get hurt, warm. I must have been four. My sister is a year and a half younger, I think she was sitting, crawling. I tried to show her how amazing it is to stack blocks, but she seemed disinterested. I think I even got her to stack two. No more. Actually, I think I got maybe five high. There were arch components, and a big trangular block, for a Roman forum look. I might have stacked two columns, and put that on top. See, I don’t clearly remember that any more, I remember the thrill of getting to three, and once that was mastered, the rest was down-hill.
I remember what the basement looked like. Grey enamel floor. Stairs in the center, no railings. Work-bench to one side, open space to the other, and then the furnace room. I could draw a plan, right now; I remember it photographically. Well, I did spend a lot of time down there. 79th and Justine, Chicago, Illinois. I remember a lot of that interior.
I remember the day I learned to read. Fox in Sox. Doctor Suess. Mom had a record of that, vinyl LP. She put it on. Somewhere in the middle, I realized that the words I was hearing correlated with the symbols aka words on the page. Put it on again, from the beginning. Sure enough! The first 3,6,9,12 words correlate perfectly! The first two or three pages are similar, having similar arrangements of words, but subtly different, and from those subtle differences, I could tell that the spoken words started on page one, and not on page two or three. That they were in order, and not backwards order, or jumbled. The were perfectly synced, and started at the begining. I got so busy verifying the correlations on the first three pages, that I lost track on page four. No matter. Start it again. Yes, they correlation between sound and words persists through page five. I form a hypothesis: I bet it works that way, to the end of the book (which seems impossibly long, but there we go...)
I remember explicitly formulating this hypothesis. Of making this prediction. Prediction is the wrong word. Nor was it an “a ha” moment. I mean it was, but more like, “gee, I bet this goes on to the end”. Not betting with money, but more concretely: if I were to listen to the sounds again, they would match the words. The ability to listen to sounds again was unquestionable, a subconscious given, not available for analysis. Ditto the looking at the pages of the book. These were not topics of awareness. What was in the awareness was that if the actions were repeated, the correlations would persist. Perhaps inference is the right word. Prediction is the act of seeing something (visually) and knowing what will happen next (in time). But this correlation was not in time or space, it was abstract. Thus, I was not predicting anything. Rather, I made the inference that the sounds and the words are corellated. On the third or fourth listen I got maybe ten pages in, to the part “Knox in sox on fox in box. With a paddle. On a noodle eating poodle. ... a poodle battle paddle noodle eating poodle..” I got tangled up in there. I think my Mom didn’t want to listen to it one more time, so that was it for the day. I got to finish the book, and eventually memorize it, over the next week. But that was it, that is how I learned to read.
A very conscious process, with explicit conscious formulation of hypothesis. Starting with a dawning awareness of correlations, the game was on: a sleuthing, a analyszing a detective mystery: if we go back, and play the record again, then the words wer correlate, and they will do so exactly, and not just in some impressionistic form, but precisely. All this was in my conscious awareness: that it could have been merely “close and suggestive”, and my hypothesis was that, no, it would not be just “suggestive of” but that it would be exact. I was very concerned with lacunae. What if the spoken word skipped over pages? I paid attention to flipping the age: that the sounds, the spoken words, would correlate with what was non the next page, not skipping a word or two, not sliding in some syllables that preserved the beat and rhyme, but failed to actually correlate with what was printed on the page. All this was in my explicit conscious awareness. You, dear reader, might think I am confabulating, but I am not. This is what my memory functions recorded of the incident. They recorded the process of awning awareness, the inference, the hypothesis formulation, the explicit formulation of multiple competing hypothesis (that the correlation was poor, inexact, skipped over words...) the surmise, surmission, that the correlation would be exact. The hope that it would be exact. Lurking in the back was even a sense of disappointment: if the spoken words failed to correlate with the text, I would be disappointed. A grand insight would be dashed. Reality would be random and vague and blurry. I wanted it to be sharp. I hoped it would be sharp. This is the emotional side. My memories do a poor job of recording emotions, but in this case, I know for sure that it would have been a disappointment, if the words didn’t correlate, and that this sleuthing adventure would be quickly abandoned, and forgotten, if this was not the case. I had better things to do with my time, than to listen to some artistic impressionistic verbal recital that vaguely dealt with the same topics as the written book. I mean, that was fun and OK-ish, but definitely weak sauce. I could do something else. Like maybe wander into the living room, or something. There were lots of other interesting things to do. Crawl under the table, or something.
Of course, I remember the floor plan. Visually. The radio, Blaupunkt. The record-player, in a cabinet above, a cabinet my father had made as a college design project. We still have it. It’s up in the attic now. The aluminum legs are not quite strong enough to bear the weight. Its modern. It looks like a Mondrian painting, but furniture. Three open bays, a fourth bay with a black formica door. But I wander off-topic. Of course, everyone remembers many things, for may different reasons, in many different ways, in all sorts of different abstraction settings, with different kinds of focus on what was important, and what wasn’t. Some people are ruled emotionally much more; others are analytic. I suppose I have to class myself on the analytic side. But I’m also normal. I’m good with the visual arts. I like music, I could play guitar. I like sports. Socializing with other people is my weak spot; I don’t do much of this. i think my parents are partly responsible. They knew I was smart, and they very much did not want me to hang out with other kids, or, at least, other kids who were not Lithuanian. SO I got Audrius as a good friend. Audrius was not a genius. But I digress; this is not meant to be about my childhood, but about AGI. So, lets get back on track. and that means more autobiography, before I tackle AGI head-on.
My aunt taught me how to read. Aunt Irena. When my parents visited, she gave me and my sister some Donald Duck comic books to look over. She had quite the collection. (She also had first editions of Ancient Greek poetry, Sophocles, or something like that. She loved to read. I have a photo of here, knee-deep in Lake Michigan, with two other friends, holding a book up. In water, With friends. Books don’t go into lakes, with water and friends. But this is my Aunt Irena. So...) Anyway, so my uncle walks in, and catches us red-handed: we are merely looking at the pictures, and not actually reading the text. And it is clarified that at least I know how to read. My sister, maybe not quite yet. Unclear. But me, I can read, and my uncle is demanding in that way: you will submit a book report. You will read this, and next time I see you, you will submit a book report. This is the kind of threatening demands he would make. Take fun things and turn them into not-fun. My aunt intervenes, I think. She’s much more gentle. She says, don’t grill them. Never mind him. It’s OK. But you really should read the words.
And they’re right. When you read the words to a Donald Duck comic book, the story really has nothing at all to do with what you imagined it was about. It’s completely and totally different. The words and the pictures kind of fail to correlate entirely. The pictures tell one story, but the words tell a quite different one. The pictures are only there for illustration, decoration. They loosely, impressionistically illustrate important events in the written text, but only loosely. This comes as a mixture of disappointment and surprise, and an acknowledgment of defeat. My defense to my uncle was that I already knew what the story was, because I could tell, by looking at the pictures. I didn’t have to read no god-damned words. I didn’t swear, of course, I didn’t know any swear words. But emotionally, it was like that. Fuck the words, I don’t need no stinkin words. I can tell what’s happening from the pictures, and goddamned pedants like you want me to fucking suffer and read fucking words for something that’s already obvious from the pictures. This is what went through my mind. Fuck this shit. Words. Screw that.
And yet, I sort of had to acknowledge that the story plot, as told by the pictures, was pretty friggin blurry and vague. I spent a *lot* of time decoding those pictures, trying to figure out what the story was, and failing. The panels in a Donald Duck comic book DO NOT TELL A STORY. Disney sucked, in that way. He could illustrate, but he could not make his illustrations talk. They were mute snapshots. He had to fucking fall back onto words to get the point across, and those words really for the most part had almost nothing at all to do with any implied plot-line you could extract from the pictures. This is what I was thinking. This is how I thought. Well, I wasn’t directly critical of Disney, not yet, because I hadn’t yet discovered this non-correlation. But I did read one or two or maybe three comic books that day, and I do have to say that Disney wrecked the magic. There was magic in the pictures, and the words fucking wrecked it. I mean, the words were fun, and I do have to say that the plot lines were far, far more complex and sophisticated than what the pictures told. So, if you could gain satisfaction from reading words, then I guess that’s an OK thing, but it came at the cost of ruining the pleasure and enjoyment of looking at the pictures. So, yeah, Disney sucked.
I mean, I read a few more comic books in the years to come, but it was never actually fun. It was a pass-time. It was an OK way to spend some time, but it was not something I looked forward to, not something were I’d think, wow, now I get to do this, can’t wait! Disney ruined comics. I wonder if this is an issue with Disney, and other artists don’t have this problem, or what. But I think this stuff is invisible to adults. Some adult somewhere would have to take active, conscious effort to do better. Well, look, maybe its like one of those New Yorker “write a caption for this drawing” contests. See, what Disney should have done was to draw the pictures first, and then given them to someone else, to come up with a story and plot. But I think he was an illustrator. He wrote the words, first, and then just illustrated. I have no clue if he was conscious of this. If he was aware of this, and did this intentionally. I’m thinking he didn’t. He thought he was creating something fun, imagined that he was creating “magic kingdoms” but I can personally attest that it was the opposite. He destroyed magic. There was magic in the pictures, and the text fucking destroyed the magic. And the swear word “fucking destroyed” is really what it felt like, when I was 5 or 6 years old, at my uncles house (apartment, actually. 58th and Dorchester, Hyde Park).
If you don’t believe me, just go to the Magic Kingdoms in Florida or California. There’s damned little, no magic in them. They’re mostly flat, boring, stupid and meaningless. I don’t understand what the fuck people see in those places. They’re just dumb. Fuck that. No adventure. Want to have adventure? Go to fucking Paris. Don’t go to the fake-Paris cafe in Disneyland. But I digress.
Oh, one digression that might be worthwhile, because it explores the world of somatic feelings. So, as an adult, working for IBM, I’m sent to SIGGRAPH in Florida. I book a hotel in Disneyland. The Woodlands lodge, when it was brand new. Construction completed just weeks earlier. I have a late flight in, evening. Flying sucks. I actually planned to come a day early, to poke around, so took an evening flight so that I would not miss too much work. And its a long drive from the airport to Disney. Stand in a rental car line, all that hassle. And its hot, and its muggy, its Florida in the summertime. And I refuse to run the A/C in the car, on the grounds of some kind of principle, or something. So, I’m overdressed, hot muggy, wind-blown from driving wth the windows rolled down. Tried, vague headache. Lugging a heavy suitcase that hurts my hands and arms and back to lift, hurts my legs to walk and stand straight after sitting in a car for hours. Exhaustion. And I walk into the lobby of the Woodlands Hotel. And its cold. Checkin counter. I mean, cold. But refreshingly cold. And there’s a scent of burning pine. And as I’m at the counter, waiting for my room key, I’m already being transported to Northern Wisconsin. A chill in the air, a mild aroma of pine wafting through the air. And its very relaxing. After that drive in the Florida humidity, its the perfect antidote. And its subtle and its gentle and its refreshing, and it feels good. It hits the spot. Now this, this is Disney magic. This really worked. This is what it took, what it feels like. Ah. Soothing, great, wonderful. Relaxing, refreshing.
Well, the wonderful doesn’t come until I start looking around the lobby. OMG. Its a cavernous Canadian, Seattle woodlands lodge. There is a two story-tall fireplace in the corner, with a roaring fire. To heat the place, because its frankly a bit chilly. And it is obviously the source of that burning pine smell. And the absurdity of it all is not lost on me: I know, I am aware that it is like 95 and humid outside, and its like 65 and dry and piney inside, so they’ve got the A/C cranked, and they are using an open fireplace to heat the place. Which is how it’s done when you’re in the Canadian woods on a cool evening, and in Canada (or Northern Wisconsin), *all* evenings are cool. And I’m looking around, and the whole place is decorated in Cowboys and Indians shibboleth. Boy-scout knives and axes. Drawings of teepees. And its luxury. So one thing that catches my eye is the floor is half marble, and half carpet, and these intermingle along curvy lines, streams. Not straight, but meandering. And I’m think “that’s pretty classy, right there That. This is luxury” I mean, the two-story fireplace in the corner, OK. But the attention to details, the floor of marble and carpet, that was something. And you know what? Those curvy lines lead to somewhere. There is a small stream in the floor. There is a small river-stream in the floor. It starts at the end of the lobby. You won’t find it if you don’t explore. It’s not there to hit you over the head, its subtle and off to one side. But it is definitely water, and it definitely is flowing, and its a stream, a woodlands stream. Like in Wisconsin. But its late and its time to go to my room, and I’ve got these boyscout themes percolating all through, coloring my emotions and perceptions and visually smack in your face, because like someone took my Boy Scouts of America Handbook, and literally copied pictures from it onto the walls of this hotel. And that is how I go to bed, go to sleep. Transported to a wonderland. So, yes, Disney is magic. Done right, its magic.
I did go there, maybe a decade later. It was run down. Too many grimy kids scratching the paint off the walls, and puking onto the carpet and sticking their grubby little hands into the woodlands stream. And I think the fireplace was turned off. But that was daytime, maybe they run the fireplace only at night. I dunno. Magic spells work only once. You can’t go back there again. This is the tragedy of being caught here and now, with your memories. There is no time-travel. There is no rewind button. Careful, Linas, lest your memories turn back to physics. I finished Tong’s Lecture 2 on Cosmology: Hot Universe, last night. I like it. Pleasant reading. So here I am, typing these words, entering them into the future light-cone of my personal sphere of influence in a de Sitter universe. I digress.
Back on track: so my Aunt feeds me sci-fi. I remember the first short story I ever read. I don’t remember what it was about, but I do remember reading it. Wisconsin. Northern Woodlands. Nothing to fucking do there. Boring, gotta do something. The Donald Duck comic books suck (there’s piles of them, up there) and so I pick up an issue of Science Fiction and Fantasy Magazine. And I pick the absolute shortest thing that I can find that isn’t letters to the editor. And its kind of disappointing, because its long. Like, over twenty pages. Oi vey. Long slog ahead. But whatever. I’m not gonna read another comic book, so dammit, if this is it, this is it. Its still early in the day, and its not like I have something better to do. So I read the short story.
And its not bad. And, you know, I could read more. (I think this is the next day.) and I think there is one more short story. But then there is this “novella”. And it is fucking seventy pages long. And I’m not going to read that, because it is just wayyyy too fucking long. And that sucks, and surely they could have put some short stories in there instead, instead of this fucking long novella. But, you know, out of desperation, I read it. It was not even science fiction, adding insult to injury. Thinking back, I think it was Stephen King. Something about a man and a high tower and a dusty bottle of whiskey. Stephen King has something with those elements. I even think they made it into a TV novella or something.
Anyway, I’m raised on sci-fi. Of course, the Asimov robot stories. And not just some of them, but I think all of them.
But I also spend a large chunk of my childhood reading electronics manuals. Why? I don’t know. There were some at the library, and it’s what I picked, and I could not tell you why I picked those instead of something else. So that’s curious: I can tell you minute details about learning to read, but nothing at all about why I chose electronics later in life. So I get to the school career counseling session, and you are supposed to pick out three different career tracks: these are printed 8.5x11 cards, and they each describe a possible career, and you are supposed to pick out three of them, something you might want to do with your life, and discuss them with the career counselor at the front of the room. So I pick three: electronics design, and radio repair, and some distant third, like maybe running a TV station, something I did not want to do, but you have to pick three, so whatever. And the counselor gets mad: you were supposed to pick three *different* things, you moron, and you picked all three the same. So it is a very very short counseling session. He says “you know, like sports, or movie acting, or something”, but I knew how utterly stupid that was. Linas, the football star? Really? I don’t think so.
So I get to college, and it is time to pick a major, and I pick physics. Why? I can tell you exactly why. A total and complete lack of imagination. Sure, history and art are options. I liked Lithuanian history, especially the knights: Karalius Mindaugas. And Algirdas and Kestutis. The union with the Poles, Liublino Unija, Jadwiga and all that, that kind of sucked. And I liked Art with a capital A. My uncle was a world-class fine artist, painting brilliant paintings. And its all lost. Well, not lost: those paintings are in my mom’s house, and some are now in Kaunas, Ciurlionoio museum donation. And some canvases in Chicago, the watch-a-ma-call-it Lithuanian museum in, wherever that is. I don’t have much dealings there. His paintings sit, forgotten, in a dark basement. It sucks. And I don’t know how to fix that. My uncle deserves wayyyyy more recognition than he’s gotten. Alas. Someday, I’ll get around to this. But I digress. Back to college. I mean, I’m like really good at art, and I took four fucking years of Art History in high school. I know this shit. But the college major is physics, because, well, because. I don’t think I even consider anything else, outside of these three. All other academic fields of study are on the other side of my personal cosmological event horizon. Mathematics would have been a distant fourth place. Later on I learn how to make mean, snide remarks about PoliSci, but I never get a chance to actually say them out loud. So physics it is.
The first-year class is a wash-out class. Starts with 150 students in a large ampitheatre lecture hall in Ryerson. Its already 120 by two weeks in, noticeably thinning, and maybe 70 by the fifth week. Half wash out in five weeks. I’m guessing the quarter ends with about 60. Year (two more quarters) end with maybe 50, and sophomore year starts with 45, and I think its mostly stable. Maybe down to 40 or so, I dunno. I’m smoking lots of pot, and partying cause that’s what you do in college. Its either that, or studying in the library from noon to closing time at 10 PM. Fourth floor was my favorite. The cool kids say the 3rd floor was the best. What do I know. I’d try the 3rd floor, time to time. I liked the 4th better. Front of building, by the window bays.
Junior year, I realize physics is boring. I’m desperate. I’m ready to slit my wrists. No I’m not: that’s just hyperbole, a hyperbolic statement. It’s just something you say, its not like I ever thought about wrists or bleeding or killing myself or anything even remotely related to anything at all like that. But its an excellent hyperbolic statement. I’m ready to slit my wrists, that’s how boring physics is. So I want to change my major. To what? I see the counselor. Well, there’s PERL. Join PERL, you can write your own major. Do anything you fucking want, a special advisor will oversee your studies. Sounds great! I say. Sign me up!
There’s just one catch. There’s requirements. Two years Latin, one year Ancient Greek. You must be joking. This is my junior year, you think I’m going to... what, you’re crazy. PERL stands for “Politics Economics Rhetoric and Law”, and if you want to write your own major studying AI, that’s in-bounds and you can do that. And I say, thank you but no thank you. I sign up for a course on anthropology. South Sea Islands, and Structuralism, and all that. Another on child development. Lots of Piaget. I sit in the math library, and study books on Turing machines and Church and Lambda calculus, my junior year. I’m drawn to it magnetically, its like the hippest, coolest and most awesome thing to be found in the library, and I fervently wish for a universe where I could be transported, to study those things full time. But I never get very far, very deep, because, you know regular homework is, like, due, and there’s only so much time for fucking around, no matter how beguiling the promise of AI in Turing machines might be.
And one of the junior-year classes is intro to quantum mechanics. And things get weird here. So, first of all, its totally impenetrable. Ugo Fano, he must be 70 by now, he’s fucking old, and I’m like still a teenager, I think 19. Much much later I find out I’m the youngest kid in my class. At University of Chicago. So I guess that makes me smart. Anyway, Ugo Fano is old and the textbook is impenetrable. It is a hand-typed manuscript, with hand-drawings. Published by the University of Chicago Press. Much later, second or third quarter, one girl in the class (the only girl? I wish I could remember her name, but I can’t. She was ranked #2 in the graduating class. I was ranked #3. Who was #1? Fuck if I know. #1 was some home-schooled kid, like fourteen, who was like, you know too fucking young to even attended the classes the rest of us did. See, I’m smart. Youngest kid in the college, who is actually attending classes. Ranked #3 of all graduating physics majors. Number fucking three. Everything in my life, I’m number three. It’s quite humbling. Even a kind of a curse. I could have been just plain stupid. Or I could have been number one and shrugged it off. But no, I’m number three. And still shrugging it off. But I digress.) So she comes back from the stacks, and she’s got a book that explains what quantum spin is, cause you know its a total fucking mystery, what the fuck is spin? And there’s this glossy, hard-cover textbook, classic crisp high-kaolin-content glossy paper textbook pages, elegant typesetting, good layout. Like a super-mainstream college textbook, the very model of what a textboook should be. And it explains spin. And there a diagram, and equations, recognizable equations, that we understand and somehow shed insight and understanding. And we are both like, wtf, why can’t we use this textbook for class? This textbook is clear. And who wrote it? Ugo Fano. Yes. The same guy who is teaching us now. He wrote it 20 or 30 years earlier, published in the 1950’s. A mainstream college physics quantum mechanics textbook. And not the only one. I think he wrote another, too. And instead of that, we are studying from this type-written, hand-drawn manuscript printed on plain white paper. This impenetrable morass of meandering re-analysis of the most fundamental and the most basic experiments from the dawn of the atomic age, trying to articulate quantum phenomena in a semi-classical language appropriate for 1910 or 1920. Thinking the way people were thinking in 1910 or 1920, before they had figured it out. Fano didn’t say so, and we didn’t know so, but in retrospect, that is what it was.
And what was that? I think, when he got old, he realized that he did not understand quantum either, and had no clue what spin was. Here, the man who helped found quantum chemistry, and MO-LCAO (Molecular Orbital=Linear Combination of Atomic Orbiitals), a man who was actually famous for his contributions ot quantum mechanics. He didn’t understand it. And so this typewritten manuscript was his last, best attempt to go back to the basics, and see if we missed something. Maybe there was a needle in the haystack. Something we missed, something important. If we only go back, and look at the evidence again. And that is what he was teaching. The raw evidence. The experiments. The minimalist, confusing semi-classical explanations of the experimental results. Confusing as shit for use youngsters. There is a reason that mainstream college textbooks win out. Even stupid kids can read mainstream college textbooks, and say “I learned something from that”. Or worse: “I like this textbook much better than that, it is much more clear.” This dooms the unclear text. Stupid people consign confusing things to the dustbin of history. The University of Chicago did not publish Ugo Fano’s last and greatest attempt at explaining quantum mechanics on glossy paper with proper fonts. They did the minimal, honorable thing to do: they at least used acid-free paper. It hasn’t yellowed. I still have it.
So, yeah, quantum is weird. My senior year, I take the first-year grad-school course in quantum mechanics. Love it. It’s great. Quantum is fugnuts weird. I think I wrote about the prof in this diary before: he’s the one who pulls me into his office, shuts the door, and makes me swear an oath to never-ever talk about quantum with ordinary laymen, people who do not have a formal education in physics. Like you know, he was swearing me into the Manhattan Project, or something.
So AI, and those classes on anthropology, and child development psychology, Piaget, that all pales and wastes away in the potent LSD of quantum mechanics. We’re not talking Disney Magic, here. This is the real thing. Not fake Paris in DisneyWorld, but the real Paris. And Paris on LSD and shrooms. That’s what quantum was. Except weirder. Like my prof pointed out, it’s stranger than any Hollywood script (I nod), it’s beyond the imagination of any script-writer (I nod). Beyond the ken of any sci fi writer. (I nod. I want to say, “what do you take me for? A moron? Why are you telling me all these obvious and self-evident things?” I had read EPR by that point in time, and EPR broke me. Look, I was 19, maybe 20. Gimme a break.) and he says: I’ll tell you why I’m telling you. And you have to swear an oath.
So yes, my studies and pursuits of AI now take a back seat to physics. The same utter and complete lack of imagination on my part that lead me to select physics as a college major now cause me to get a PhD in physics. p.s. Did I mention I finished college in less than four years? Youngest kid, and I did it in three years and two quarters. Youngest kid except for that home-schooled boy. I took the last quarter to work at LASR more-or-less full time, writing FORTRAN to analyze Pioneer-10/11 spacecraft data. For John A. Simpson. I was fucking twenty. Just turned twenty. I was also fucking. Lost my virginity a few years earlier, and well, more or less lived with my girl. Fucking all the time. Margert Edsall. My understanding is she’s Dean of Students at Columbia in New York City. So, not just any school, but like Ivy League. She married her housemate Mike Parides. Who lived in the room next door, while we fucked. He would fall asleep with the TV on. Poor guy. He’s an MD. Margarets’s dad was an MD. A world-class heart and pulmonary MD. Some Arab hired him once. Guys in dark suits, black mustaches and mirror shades whisked him off to a limo one night. I was there. They looked at me, and decided I was not a threat to Arabs. I assume Margaret married Mike because, well, Mike could get a job in New York, and I, well, I couldn’t. I’d be an academic loser, tossing and turning and unable to find my place in life. Margaret was on a track. She knew where she was going. She also had some talents for manipulation. She wasn’t mean or bad, or even controlling. But she got what she wanted. She knew how to get what she wanted. I didn’t. I was lost and dazed and confused.
So I did undergrad in under four years, but the PhD takes five. Not because it was hard; it wasn’t. It was easy. But I wasn’t serious. Physics wasn’t really my calling. It was merely something I was good at. The grass was greener on the other side. I had an opportunity to study Chaos Theory with Per Bak at Brookhaven, but I blew it. I had the opportunity to study conformal field theory with Zuber in Paris, but I blew it. I read some preprint by some russians, apply renormalization group theory to DNA, but who fucking cared about that? No one. I read a significant chunk of a book on computing, semi-Thue systems and proof theory. But I wasn’t thinking, and my housemates were like “Linas, why the heck are you reading that? Its not physics. Come watch Jeopardy on TV with us.”
I recall reading about the collapse of some small mom-n-pop bank in Oklahoma that summer. It was on page twenty of section three of the New York Times. The next day, there was another story, this time on page ten. And again, page three, because, you see, somehow Illinois Continental had purchased a bunch of overnight repurchase agreements from this little mom-n-pop bank in Oklahoma. And Illinois Continental was the largest commercial bank in all of the United States. So that merited page three. A few weeks later, it was a fixture on the front page of the first section. The Savings & Loan Crisis of 1988 had begun.
So I fucked around. And it sucked. No more post-doc. I had to get a job. I did not want to do nuclear bomb design in Los Alamos. It sickened me that this was the only employable talent that I had: making nuclear bombs. Whatever. lost and dazed and confused, I fucked up. This was the low point in my life. Couldn’t get much worse. Got a job at IBM eventually. So, actually, yeah, it could get worse. I spent what, two decades fucking dazed and confused at IBM? I learned everything, and I really mean everything that there is to know about computer engineering at IBM. There is not a topic anywhere in all of computer engineering that I did not spend at least half a year on, or more. And for what? What did it get me? The urge to slit my wrists. Metaphorically, of course. Fucking hated it, quit IBM an angry young man.
There’s more to this story. I sank even lower. I’m recovering now, but its a bit late in life for that. I’m sixty-five, not twenty. I’m still smart. I’ve been doing AGI for 15-plus years now. Leveraging both physics and computer engineering, and of course, math, to do it. And all this time, the 15+ years I’ve been working on AGI, I never actually stopped and asked “what is AGI?” Because it seems to be a self-evident question. But I want to ask that question in all seriousness now. To really explore it. What is AGI?
So here’s the catch. It’s 4PM. It is sunny outside, and I need some exercise. I am exhausted by the time/effort to write the above, I need to take a break. This is the same reason I’m not a bitcoin billionaire: it was sunny and warm outside, I needed to take a break. Installing that bitcoin miner would have been a cool thing to do, but I needed a break. So I’m going to do this to AGI, too. I told myself I’d get back to bitcoin mining, but I never did. I do plan to get back to AGI.
Here’s the deal. Talking and thinking about AGI won’t be just a few pages or a few hours. As I told my son this morning: physics traps us in the prison of the here and now, the present. It gives us things like love, which I’ve known intimately, and things like evil, which I do not. Suffice it to say that some people really do seem to be evil (and not just stupid), and to be evil from a young age. Or something. This requires some intellectual effort. And now, with AGI, we (I? no, we.) We talk of building an artificial silicon intelligence that will occupy the same prison of here and now, and it is to be generally intelligent, which means, to me, to know love and evil. So the AGI topic will have to encompass that.
And, of course, I will also ramble on about state vectors and high dimensions, and parallel Baysian priors (ahem, integrals) (Oh, I gotta copy those essays from the opencog wiki to here.) and I will talk about neural nets and LLMs. And of course high-dimensional vectors of jigsaws: sheafs, that is. Sheafs of networks. Sheaf-theoretic sheafs, and for what? The reason I have to step back and ask “what is AGI?” is because I’m getting lost in these details. Yes, blah blah agentic. Blah-blah sensori-motor. Blah blah world-model. Self and not self. And fucking free fucking will. This diary has already witnessed my flailing about with free will, and more than once. And so this is the question, the narrative: “What is AGI?” and if the answer doesn’t give proper justice and dues to love and evil, if it doesn’t give proper justice to free will and the prison of now, and if it doesn’t give justice to everything we know about computer science and engineering and physics and math, and if that answer fails to incorporate the reality of Wetern Civilization and Political Economy (and captialist economy) and the affordances for humans to manipulated the world in which they live, affordances in the sense of handles on coffee cups taht allow me to pick up coffee cups easily without burning my hands, if the answer to the question of AGI does not somehow encompass fucking everything, then it is a failure. So that’s the ground rules.
Oh and one more rule, perhaps the most important of all: now what? What is there to be done, next? I mean, in the practical, immediate, consequential sense: what is to be done next? We’ve got the OODA loop. We’ve started the first O “Observe”, and we started that with my autobiography, my curriculum vitae: a life of observering, and what i have observed. The second O “Orient”. well, there will be a bit of that, it will revisit old ground, so I’ll keep it brief. I think. I might be wrong about orientation. The D “Decide”. That’s the big one, That’s the challenge. That’s what I don’t know. That’s the question “What is AGI?” which is not so much about what AGI is, because we answered that already: its everything. So, “Decide”. Now what, What do we do next? The Act part is easy: its a long slide downhill again. One foot in front of the other. But the Orient-Decide phase: this is the trap a trap like a fly on fly-paper. I have to be able to grasp AGI, which is, well, everything, and wrestle it into a position where I can decide to act, and to do so, unlike that unfortunate fly, of getting my belly stuck to the fly-paper. This is going to be a challenge.
I thought I knew what I was going to write next, and I think perhaps I still will. But its nice outside, and I really must get to going. I’ve spilt too many words. Toodle-oo.
Oh, I am going to eat an apple first. So one or two more paragraphs.
First, lets get out of the way some basics: an AI has to be agentic. But a cruise missile is agentic, too. So this is where free will gets tangled in. I’m not sure I want to do that tangle, but it might be unavoidable. Classic AI is focused on rational inference, deduction. And I guess this is OK. When I learned to read Dr. Seuss, I was creating rational, inferential hypothesis about how my local sensory environment worked. And I was conscious of making those hypothesis. I recorded them in memory as my main intellectual activity. The actual “learning to read” was a side-show, a pleasant distraction. The intellectual heavy-lifting was the decision to look for correlations between sight and sound.
And so we can weave this together to form the first lesson of AGI. We can create a system capable of reasoning and deduction, in the very classical AI sense, but the result might just be a cruise missile. Feeling-less, emotionless, formal deduction towards an end and then boom. We can build these kinds of formal reasoning systems, but this is not quite exactly what we want to identify with as “being alive”. Cruise missiles don’t fall in love, nor would formal reasoning systems. Now, I employed a formal reasoning system, when I learned how to read. But I would like to say I am not a cruise-missile. Now, nature gave me a brain that allowed me to perform the activities of analyzing my environment, and thereby getting drawn into the activity of learning to read. But there was more: I was bored. I had nothing better to do. Well, maybe I did. Maybe I could have crawled around under the dining room table, which is a pretty marvelous architectural space, with all those columns of chair legs and table legs all about, a large open central atrium at the center of the table. A table cloth forming a curtain along the edges. Humans like to wander around in Medieval Catholic Cathedrals. They like to shop at malls with atriums. Even hotels are built like that. So crawling under the living room dining table is a thing, a real thing, and a valid pursuit as an alternative to deploying my intellectual abilities to discern sight and sound, to correlate the printed and spoken word in a Dr. Suess book. And cruise missiles don’t get bored, and cruise missiles don’t crawl under tables, and cruise missiles do not employ their deductive, theorem-proving, inference and correlation engines to learn to read. Because, I guess, cruise missiles don’t get bored.
So, yes, the classic AI concept of “logical reasoning” is important. But its not everything. And being an agent in the world is important, but its not everything. Having a world model is important, but not everything. The fucking thermostat has a one-bit model of the world: on or off, and it has the agential motor control of a header, coupled to a thermometric sensor. Does a thermostat have free will? The conventional, mainstream answer would be no. Does a thermostat get bored? I think not.
So where does free will and boredom come from? I don’t know. But one more aside first. Liebniz had the idea of monads, in pursuing the question of intelligence: splitting up intelligence into smaller and smaller pieces, and so we get panpsychism. The thing is, Liebniz did not know about phase transitions. I’ve already talked about percolation in this diary. Less than a certain fracture, oil does not flow. More than that, it does. And so with intelligence. There is a phase transition, below which there is no intelligence, and above which there is. We do not know where that phase transition is. And so perhaps that is one of the central questions of AGI: where is that phase transition? And where are cruise missiles located with respect to that transition? Or, fuck all, ants. Or amoeba. Yikes!
I’ve eaten that apple. Once again, time to go. Later.
30 December 2024, 8PM
Later in the day. Post shower. What am I doing here? Writing a diary, obviously. Not science. Nothing I write here conforms to any conventional standards of science. Nothing would pass peer review. Amateur philosophy? See, the problem is most famous philosophers were crackpots. Smart, brilliant, even, but making inferences far beyond the ken of science. Give them some credit I guess, for venturing into the unknown. Subtract points for making assured claims with nothing but hand-waving for support. So I don’t want to do that. Feynmann might advise “shut up and calculate”, but I already calculate a lot, so coming up for air, and asking “why calculate this and not that?” seems like a legit thing to do.
The problem with saying “intelligence appears on one side of a phase transition” is that we don’t have a coherent definition of intelligence. Clearly animals have it. Is it limited to neural nets? One can make coherent arguments that it is not. But is the behavior of slime molds “intelligent”? One slides down a panpsychic slide, attributing intelligence, or fractions thereof, to simpler and simpler systems. There’s no obvious phase transition in there, somewhere.
What about free will? A few weeks earlier, in this diary, I came to conclusion, arguably total nonsense and hallucination, that free will arises at a Cauchy horizon. Now this is meant to be taken not literally, but metaphorically, but also meta-literally, in that there might be differentiable, causal structures appearing in our brains that have singularaties, singular solutions. So, first lets regurgitate the conventional reasons why my idea here is fundamentally bad. First, one hand-waves, “quantum gravity”, implying that if we had a theory of quantum gravity, then the singularities (in black holes) go away, and everything is hunky-dory, and no more Cauchy horizon, tah-dah. But that’s physics. In math, we still have the issue that we can write down systems of equations, that happen to have applicability to physics, but those systems of equations admit solutions that are wonky. Quantum gravity does not alter the math one whit. The formal mathematical phenomena remains.
What makes the Cauchy horizon interesting is that its not a set of measure zero. We’ve got a gazillion examples of singularities on the complex plane, but any geodesic-like curve one could draw, well most of them would have to bump into a set of measure zero. Now, there’s some fascinating descent into the theory of the sizes of things, which promptly leads to the Axiom of Choice, and to Borel Hierarchies, and Cohen’s forcing and all that. Wikedly interesting stuff. But the Cauchy horizon is not like that: living between the cracks. The Cauchy horizon is big and bold and measure-theoretically large. There’s no Alexander’s horns here, No knots sitting the three-spaces that bound 4-spheres. The horizon is big and bold and in your face. Its not going away.
So my question is: are there any dynamical systems, aside from gravity, that exhibit Cauchy horizons, and might any of those dynamical systems appear in settings where intelligence arises? Can I build some mechanical or fluid-dynamic system, some analog, in which there is a Cauchy horizon? I’m thinking yes, I can. Well, maybe not me, but in principle, and maybe it is doable, and maybe someone has done it. Gonna search-engine that later. Say its doable, then are there any biological systems that would have that? We could go all reductionist here, but that’s absurd because it would imply that we’d need quantum gravity to explain biology, and that is a non-starter. But still, are there any systems in nature, outside of the setting of gravitation, that exhibit a Cauchy horizon? If so, then can I ascribe this some property of free will? Anyone who reads this and is smart enough to understand what I’m saying will say “fuck no, Linas, that’s crazy, that’s wrong. You’re nuts.” So whatever. fuck you, too. See, I’m looking for free will, because if I can find that, it provides a workable definition of intelligence: things that have free will are intelligent, no matter how small and simple they are.
OK, so here I anticipate another obvious objection. I can hear it now: “Linas you are talking about a random number generator, and mechanical systems hooked up to random number generators are not intelligent.” And this is true. But the Cauchy horizon is not a random number generator. I want to argue more: it is an all-possibilities generator.
So here. Conventionally, all-possibilities appear in the partition function:
Since the action contains derivatives, the discontinuous possibilities get a weighting of zero and don’t contribute. Now, there are severe measure-theoretic difficulties plaguing the partition function, but that never stopped the physics community. Some what I’m now saying is, what if the action doesn’t suppress a sizable number of non-differentiable field configurations
? Yes, of course, I’m piling on a mathematically ill-defined idea on top of something that is already ill-defined when its behaving nicely. What if free will and choice are those things that glue together the disparate universes?
To be clear on terminology: a single choice of
is a “universe”; universes and
are in one-to-one correspondence, and the integral
is an integral over all universes. The exp i Action just gives the weighting or likelihood of that universe contributing to the partition function. FWIW, Bayesian priors work exactly like this. Now, by convention, one is to imagine that all of these distinct
are entirely independent of one-another. Nothing one can do in one can influence another. Perhaps oe imagines the
as sheets of paper, stacked. Close, but nothing written on one page bleeds to another. That’s the conventional view.
Now what if, instead, the Cauchy horizon (or it’s metaphorical replacement) is where all these sheets come together? The hand-waving argument would be that its like a singularity, say, the location
in the complex plane for
. If you sit on a curve and fly into
you don’t die, you just come out on every or any other sheet. If there’s going to be a conservation of curves, then you’re allowed to come out on any sheet of your choosing, but only one. What is that? A random–number choice? A flip-coin choice? Some axiom-of-choice thing? I don’t know. I don’t think its a “random number” and I don’t know what it means “to choose” in this situation. But this is an example of where a singular point glues together many sheets. But, you say, “those sheeets were never independent universes. You could always get from one to the other by circling around the pole, gaining a factor of
each time around”. And, yeah, well covering spaces tend to be simply connected. Or perhaps that’s the definition of a covering space: its that simply-connected thing.
I dunno. Perhaps I’ve gone off the deep end. But it seems like free will needs this kind of lugubrious theorizing, because otherwise, we are trapped with the nitwits who insist we don’t have free will and its all just random numbers, but those people are nitwits. And they say, never argue with a fool, because the onlookers won’t be able to tell the difference. So I’m not gonna argue with those fools. Instead I’ll do some vague mathematical fantasizing. But really. I think part of what I sketch above has legs. I think something can be made of it. Tightened up, made concrete.
But this puts us in a chicken-and-egg scenario. If intelligent systems are exactly those that have free will, and I cannot give a workable definition of free will, then I’m hosed again. There are others, who are not nitwits, who think panpsychism is the answer. And anyway, its not like the panpsychists can offer up any kind of theoretical mechanics that allows a workable definition of intelligence to be coded up in software.
So I seem to hit a dead end here. One that I’ve hit before. Although this time, I think I made a tiny amount of progress.
Are there other ways of thinking about AGI? Well, I suppose I could take a more mundane and pedestrian view. Lets take a moment to walk through those.
So one is the agentic system. A system that has a model of the world, a distinct inside and outside, a sensori-motor system. But we’ve already noted that thermostats and cruise missiles have this, and I don’t want to give those any ascriptions of being alive or intelligent.
Then there’s explosive replicators. DNA embodied in bacteria, etc. explosively replicate as long as there’s food. And conventionally, we say bacteria are alive. So I’m OK with saying explosive replicators are alive. But that’s also not AGI. I can’t build a computer model of a bacterium and pass it off as AGI, because... because why? Because it cannot be hooked up to google and work as an oracle for answering questions.
So is an oracle for answering questions, is that AGI? Well clearly, good AGI would be an oracle (well, oracle-like in the informal sense, not the computer-science sense). But the converse ain’t true. Oracles aren’t AGI.
I felt I was onto something, when I started talking about boredom, and love, and evil. Love is ... well, love can be explained away as some limbic, somatic, reptilian-brain response for procreation, but anyone who has been in love knows that this is an inadequate, mechanistic explanation offered up by nitwits who like to pretend that they’re know-it-alls. I can’t speak for the poets, but the movie “The Fifth Element” with Bruce Willis and Milla Jovovich does get the general nature of the thing correct.
Dafuq. I used the word lugubrious. I can use it again. Wander down the hallways of love, boredom and evil and kind of not get any closer to a workable definition of AGI than I didn’t have before. Is it like Art? “I can’t define it, but I know it when I see it?” But I’m not trying to reduce Art to an algorithm. I am trying to reduce AGI to an algorithm but it seems right up there with trying to reduce love, boredom and evil to an algorithm. I mean, if you can’t define it, you can’t create software that works at that level.
And the risks are equally obvious: like creating that 18th century robotic schoolboy, sitting at his desk writing schoolwork: a simulacrum can be created, but that’s not the “real thing”. The Polish sci-fi writer, Stanislaw Lem, has some story where reality is shown to be some LP recording, the mechanism of which is dicey and jamming. I can build a simulacrum of love, but that’s not love. Again, we slip into philosophy. I had a book, while still a teen, Daniel Dennet. It was OK. It did not light my fire. But it did illustrate one story with a cute robotic mouse with winking glowing LED eyes, and cooing sounds, and the protagonist is asked to smash it with a hammer. Its just a freakin robot, but we have this mammalian gut reaction to little furballs. There’s even a TV commercial, from Ikea, that features an old sad desk lamp abandoned in the rain by the garbage. And a full length feature film, Brave Little Toaster, the ending of which is heart-rending. So these are the mammalian, limbic, somatic shadows of existence that we are immersed in. And my definition of AGI says that it too must partake of this world. And of course, I can create some software that claims that it does, but this is like that Star Trek episode where Data is placed on trial, accused of not being an actual being, of being a machine.
Where’s the phase transition to being-ness? Are you getting bored by this? Because I am. Clearly mammals are beings, and we do down that path and end up at panpsychism again.
You want to know how crazy I am? I’ll tell you how crazy I am. If the universe doesn’t stop me, first. Every time I’m about to do something stupid, the dog barks, and I say to myself, “this is the universe reminding me to stop doing this stupid thing”. And I’m typing this on a laptop with a shitty keyboard and a shitty touch-pad, and I’m making vast amounts of typos due to the mechanical misbehavior of this system vs. my hands. and every time I’m about to type something really exceptionally good, it gets tangled up, and again I think: this is the universe trying to stop me from spilling it’s secrets. That’s how crazy I am. I get those micro-thoughts, and I give them credence and credibility just long enough to wonder if its true. Because you know it could be. Who the fuck knows. The universe really could be fucking with me like that, because who is to say it isn’t. We already have the Mandela effect. I didn’t invent it, but I do suffer from it. I remember Nelson Mandela dying in a South African prison back in the 1980s so what the fuck is all this about him still being alive and all that? WTF Really? Maybe universes do cross over, or maybe the combination of statistics, news reporting and neuroscience just makes me victim to a mass delusion. Who is to say?
Oh, and then there’s math. I might have touched on this a bit in this diary, but really I could do more. Math is a potent hallucinogen. I don’t feel like explaining this right now, but for a quick tour, look at what people said about the Cantor set, and what he did. It’s crazy-hallucinatory. Obviously. Then there’s the various paradoxes of measurability. Say the Banach-Tarski paradox. Crazy shit. There’s lots more. Anything to with infinity. I think I’ve mentioned before the insanity of weak convergence in Hilbert spaces. QM is insane mostly because of this one thing, but that means that the problem lies not with QM, but with weak convergence in Hilbert spaces, which is the root cause of quantum weirdness. So its not the physics that’s insane, its the math. And so if math, the most staid, assured, unassailable, confident rock-hard foundation-stone of all things knowable: I mean really, who is going to argue that 2+2 isn’t 4? This is a fact 2+2=4 and nothing you can do can change that. Its the rock-hard foundation. And that foundation includes fucking goddamned fucking prime numbers. And Banach-Tarski. And weak convergence in Hilbert spaces. And axioms of large cardinals. And Borel hierarchies. So fuck me, fuck that, math is fucking insane. Our foundation-stone of reality, 2+2=4, is simply the logo stamped on a universe-sized tablet of LSD. And fuck me, what, you want me to algorithmicize this, and build you an AGI? I homunculus based on the the mystical elements of the Kaballah? Really? You don’t need to get mystical. The mystical is already here, right now. Pervasive and permeating pan-mysticism. Sheesh.
So I must bring tonight’s OODA loop of exploring AGI to an end. The observe and orient stuff ended with disorientation, and identified the proximal cause of that disorientation. Its built into the fucking math. So, deeper than being built into the fucking universe, its built into the fucking math. Excuse the swear words, but I know obscenity when I see it, and math is obscene.
Decide and Act. Well, the mundane decision is to tough it out. Put on that heavy back-pack, tie your boots and go out into that storm. Hump it over the mountain. Metaphorically, this means go out and read more academic journal articles, and participate in the day-today quotidian intellectual activities of the social world around me. This is, I guess, an admission of defeat. Not that I was ever expecting to win. But laser-like focus on a narrow topic is an excellent way of making dramatic progress, and I am anything but laser-like here.
Another analogy. I could moan about number theory here, instead of AGI. Or I could just go out and do it. I think I did pretty well with the beta transform: hundreds of pages of laser-like, focused, insightful results. And no one cares because who the fuck cares about iterating
? Almost no one. Maybe more than the number of people who care about this diary. Because the beta transform, the iterated
is considered to be unimportant. And see, that is my dilemma. I could spend the waning years of my life making sharp, insightful progress on narrow topics that are not important. Or I could moan about the inaccessibility and ineffability of AGI. Or I could just fucking give up, and just do something that would bring me closer to nvidia gpus and weights and shut up and calculate, as Feynmann would say. Or I could cast about. Because, see, all these other things are boring. I don’t quite really want to do them, because they’re not ... they’re not worthy of my time. They’re not a valid activity to while away the years. By contrast, moaning about the ineffability of AGI into this diary does seem like something worthwhile.
Let me be more direct. I think there’s something here, and I think I could even make a bit of progress, if I could get my hands on it. But like the four-year-old stacking blocks, the blocks keep fumbling out of my hands. Something, something. Agential sensori-motor. Something something category theoretic. These blocks. I can almost assemble them. And then the self doubts: I assembled some blocks. Is that a house that can be lived in? Is it a Roman coliseum? No. Is it AGI? err. Fuck. The blocks keep slipping away. But I think I’ve almost got my hands in it. If I just try a bit more. Something something Basal cognition.
Well, reading more is really not a bad idea. It takes me back into the first O of OODA: more observation. Its a deferral of decide and act. Its more orientation. How much longer to decide and act? What’s there to decide, if I can’t figure out what the fucking problem is? I’ll sleep on it.
I finished Tong’s Lecture 2 on cosmology Lecture 3 awaits. Sweat dreams!
Oh, footnote. I’m loosely spell checking above, and Chinese Room pops into my mind. I always hated the Chinese room argument, I thought it was dumb. I see why some people feel like its worthwhile. But those people are just dumb. The Chinese room is like asking the sand grains in a sand-pile about how they know when to avalanche. You can look at any given grain of sand all you want, microscopic examination, and it won’t get you to an adequate understanding of avalanches. So the same with the Chinese Room. Yes, you’ve got all these guys running around programmatically stacking algorithmic inferences and deductions, using the finest in proof theory and lambda calculus to do it, and then it all avalanches, and no one saw it coming.
And so maybe that’s my definition of AGI. Its a proof-theoertic stack of inferences, so tall and so carefully balanced, hinged on countless delicate assumptions, that nudge some tiny little Bayesian prior, and half the stack comes sliding down in an avalanche. That avalanche is no longer algorithmic certainty, proof-theoretic provability carried out by minions in the Chinese room. One of the shmucks spilled a bottle of ink on the instructions, faked it and it all comes sliding down. This is what’s wrong with the Chinese Room. The philosophers were so busy studying philosophy, that they didn’t learn any physics.
Of course, my two-paragraph rebuttal of the Chinese Room is literary and allusory. What, exactly, in a stack of crisp proof deductions, comes tumbling down? Nervous breakdowns are breakdowns. Electrical dielectric failures are breakdowns. Tears, cracks, shattering. What, exactly, is supposed to be the analog of dielectric failure in symbolic reasoning? What’s avalanching? Well, I earlier stated that 2+2=4 is rock solid, incontrovertible, unchallgengable, unalterable. I skipped mentioning 2+2 mod 3=1 In this tower of deduction, was there some quotienting there, where no one was paying attention? Something in a sigma-pi hierarchy modulo some for-all, there exists, that has some alternative interpretation, alternative valuation, different outr model than the intended model? That would avalanche. If something has multiple models, then what is true in one model might not be true in another. If the Chinese Room guys were working in one model, but really there was some other semantic interpretation, they were deriving things that were falsehoods when applied to the inner model. Some downward Skolem-Lowenstein lemma type thing. That would be the “avalanche”: you thought we were working
but I thought we were working with
and so you’re getting not just contradictions, but avalanches of incompatible inferences. That’s the avalanche. That’s how the Chinese room fails.
Modulo is weird. Learned that from
but modulo gives us homogeneous spaces, and it gives us algebraic varieties and schemes, and modulo gives us model theory, the “algebraic geometry without the fields”. The place where
gets weird has to do with Cantor-setting our way to infinity, the tension between countable and uncountable infinity. And this is merely the first level of the sigma–pi hierarchy. There is an entire tower there, ready to fuck you and Banach–Tarski. Pleasantly fuck. While you’re tripping on LSD. But fuck in surprising ways. The people who came up with the Chinese room never cracked open a book on model theory, and never learned how to get laid. Uptight virgins, they are.
See? I’m lost again in the insanity. By contrast, LLM’s and transformers are very very concrete things. Specific, and Nobel–prize worthy for Geoff Hinton. I’m sitting here, fucking around and in awe of nothing in particular, and everything everywhere, all at once. The movie I mean. The movie with Michell Yeoh.
31 December 2024
After yesterdays histrionics, lets see if we can do better today. We can take the pragmatic definition of AGI: it is that economically viable thinking machine that can replace high-priced engineers (and other high-priced humans) in the delivery of economically viable services. I’ve been talking to one fellow who wants to digest electronics diagrams and the surrounding English–language documentation to automate a repetitive process that engineers currently perform.
This is an eminently practical desire, the kind of which has been driving economics since about forever. It is also a task on the forefront of what is barely possible and achievable with current technology. Insofar as I personally want to toil away on the creation of AGI, this is perhaps a task in which I should invest significant intellectual effort.
Lets for a moment imagine what this might be. Or not. Technology is in rapid flux, tools, features and functions are rapidly changing. What is commercially available right now can be adapted in this and such a way to the task. The tech stack selection I might make for a customer might be different from the tech stack I might wish to make for myself.
Lets do some forecasting and prognostication. I have to be careful here. First and foremost, we have the sci-fi writers, who are quite good at looking at some present-day situation and extrapolating it to the future. We’ve got the TV show Black Mirror, which makes dark prognostications. Any number of youtube scifi shorts going in any number of directions. Amateur gatherings, like Less Wrong, exploring, like ants working a food source, exploring the implications of this or that. Some are vastly smarter than others; Scott Alexander with Slate Star Codex rises far above. Some prognostications are economically valuable: Peter Zeihan seems to make a good living cooking up geopolitical ideas of all sorts. In short, there already is a rather extensive effort, work-front looking at present trends and extrapolating them into the future. It is hard to stay on top of it all. I’ve tried, and there are others who devote fulltime attention to this.
Why is it hard? For simple economic reasons: There are thousands, more, tens of thousands, and yet more, hundreds of thousands, if I count twitter posters, who are actively engaged in this. They are able to be actively engaged because, thanks to the miracle of modern capitalist economics, basic wants like food and shelter have been taken care of, and secondary desires, such as material accumulation and entertainment are equally fulfilled. This leaves one with lots of spare time to focus on tertiary issues. Tertiary here means very much the kind of stuff that, in the past, was limited to very few: usually academics, powerful politicians, and those administrators working in the court of someone powerful (king, president, CEO, executive.) IBM had a decent number of employees who “did nothing” but prognosticate the future. White Plains was jam-packed with them: executives who had a base hit, not a home-run, and maybe they could do it again, it was hoped.
So my sitting here typing and hoping to foresee something about the future is already a lost cause: I cannot single-handedly compete with all that. I could contribute to it, if I worked in a public-facing forum. Owen says I should create youtube videos. Or teach physics at University of Austin. The second option is vaguely appealing. I could see doing that. It could be fun.
There’s a different kind of prognostication, of the form done by David Chapman on Meaningness. In a different way, by John Vervaeke in his lecture series on the Meaning Crisis. This (these) are again very modern developments. Yes, sure, the bourgeoisie of the 18th and 19th century could have nervous breakdowns because the meaning provided by society did not align with innate biological (somatic) drives. And then there are the Shakers, Quakers and any number of Protestant sects attempting to realign ways of existing with neurological drives, attempting to provide an all-encompassing answer, if not an eschatology. What’s curious here is that the Quakers expose this as a modern-day example of the Meaning Crisis in an agrarian society. This is useful, because we don’t have this for the Romans. Agrarian, politically very advanced, but the written record that the Romans left behind does not document psychological suffering. One does have to wonder why that is. Is it because the people who prepared Roman History for us, from Tacitus to modern times, have merely overlooked this? Is it because the society was too preoccupied with the act of living to get caught up in the doldrums of vague, unspecific dissatisfaction with life, building into an outright crisis? I don’t know enough about Rome to say. Perhaps this is well-explored somewhere.
And this is another issue: everything is well-explored. Again, because of the economic richness of the current society has allowed vast numbers of intelligent, educated humans to explore all sorts of nooks and crannies of the noosphere. And the provisional definition of AGI is that it will do more of the same, at least, for the economically important tasks, which includes predicting the weather, designing rockets, and working out the must-have Christmas gift for next year.
The last may not fit. As a literary device, if you were paying attention up to now, you might be thinking: “Weather, yes. Rockets, yes. Christmas gifts? Oh what the fuck. Let me turn off my brain now and not explore that, and keep reading some more.” So perhaps I introduced an intellectual discontinuity by elevating cheap consumer goods, marketing, and base, childlike desires for baubles and toys to the same level as serious topics like rockets and weather.
I did this to hilite another base Western Civ. working assumption: the assignment of priorities to activities, and the relegation of other activities to unimportant trivia. Childrens’s finger-paintings are generally not valued by anyone other than the parents, and for good reason: they are commonplace, just like rocks, trees, field mice, other humans, and stars in the sky. The first four can be economically exploited. The stars, not yet. Astroids coming soon, though. Heroin addiction is not considered to be valuable. It can be exploited economically: ask any drug dealer about details. Socially, and for good reason, we do not encourage it. Alcohol and nicotine are OK, though.
I’m slipping into another groove that I visit and wrestle with: the entropy landscape from chemistry, bacterial quorum sensing, slime-mold decision making, the invention of neurons in jelly-fish as a mechanism for low-crosstalk, high speed neurotransmitter star-gate transport, and then up through neuroanatomy to humans. And of course it does not stop there: it continues on up into the economic world. And it feeds back: the nicotine industry supplies brains very directly with a desirable neurotransmitter. Christmas toy baubles are a few steps removed from the direct hit of nicotine or heroin, but, in some ways, drive the same, or similar neuro-anatomical, neuro-biochemical circuits.
I once read a SciAm article on the mechanism of nicotine addiction: it was a stack of 5 or six chemical and neurological feedback loops, working at different timescale, each one of them craving nicotine. One feedback loop involved reuptake channels in synapses. That functions on the one-minute timescale. Something else, I forget what, provided feedback at the 15-minute to half-hour timescale, and is responsible for chain-smoking. Other drives function at the week and multi-month timescales, making nicotine addiction hard to break: even if you shut down the hour-by-hour craving, there is still that circuit, lingering in the back of your head, that remembers how pleasurable smoking is, and reminds you, month after month, that, well, it ws pleasurable. That’s all. Have one now and you could relive that pleasure.
Huh. Relive that pleasure. This is the rewind button that the physics of here and now does not have. We cannot time-travel back in time to change things, but we can recreate prior conditions and relive them again. And again and again, because those prior conditions were pleasurable.
How do I know they were pleasurable? Because I do, the same way I know love, hate, evil. Unexamined, except by the great literary authors of the centuries. Poets, too. Yesterdays angst makes it clear that the reduction of Great Literature to Algorithms is not quite here, yet. The algorithms, like Data in Star Trek, or the Chinese Room, or, for chris sake the LLM’s can maybe fake it for us, and create the appearance of Great Literature, but there is no reason to believe that LLM’s actually suffer from nicotine cravings. The biological mechanism cannot be traced. An LLM can tell me all it wants about craving cigarettes. It can tell me about how it remembers eating ice-cream in childhood. I know both are a lie. This is the point the Chinese-Room people were trying to make. And, at that level, they were perfectly correct. They were only wrong in elevating it up to some sacred philosophical principle.
Nicotine and heroin are good for this kind of analysis, because we understand the physical principles sufficiently well to know when they apply (i.e. in animals) and when they don’t (i.e. in LLM’s). The same cannot be said for love, boredom and evil.
Nicotine and heroin are nice, because they also provide a scalpel with which to dissect Western Civ. The scalpel reveals that it is the drive to greater complexity that seems to matter. Heroin addiction is frowned upon because it is an economic and social waste. So, perhaps like leakage currents in an integrated circuit: it siphons off what is otherwise usable energy. The bio-feedback circuits build up to a stack of 4 or 6 cycles deep, and then no deeper. Maybe they layer on one or two more feedback loops: the economic industry that produces heroin. The feedback here is financial. But, in many ways, it is destructive: economically, it seems like a net-loss.
I’m taking a modern view. There is a depiction of morphine addiction in a Russian izba in the early 20th century, in Andre Makine’s book, Dreams of My Russian Summers. And that book is what, in the end, I am struggling to work with. When I say “Great Literature”, you are free to choose any example meriting that moniker. I am not well-read, so a paucity of familiarity which such things. But Dreams of My Russian Summers hits, and hits hard. I just now skimmed the Wikipedia article, and evoked some suppressed sobs at the first mention of Charlotte and WWI. The “rock” from Verdun, to be precise, that’s the trigger. Because that rock is, of course, a bullet, and it is a signifier for the mass collection of very personal memories. Tragic memories: the soldiers died by the millions. Time has passed; they would have died of old age, had it not been for WWI. Clearly, dying of old age is preferable. But why? This is like, a stupid question. An unexamined question. And the russian setting is perhaps appropriate: russian culture devalues human life. They are quite happy to send young men to die, as long as it elevates the pride of the country. So, “dying of old age” is preferable to, erm, European cultures. Not so much in other parts of the world. And that’s, well, why it is a worthwhile question to explore.
At play here, at least for russian culture, is national, cultural pride. I want to write a paragraph that reduces cultural desires to entropic principles. I could probably even do that. An aside is needed to talk about the Siloviki: the intentional genetic breeding of humans to be soldiers, policemen, executioners and torturers. To be a part of the state apparatus of control. The structure here is not just of genetics, of breeding vicious humans the way we breed vicious dogs or fast horses, but also of the state apparatus itself: a deleterious socio-political structure intent on the suppression and destruction of humans.
Am I a russophobe? Why yes. After witnessing the Ukrainian war, there can be no doubt. As if Romas Kalanta were not enough. “But not all russians are bad”, you might say: sure of course not. But when you have a cancerous lump, are you going to pick through the cancer cells, and decide “this one is bad, this one is good, and this one, we’re not sure about”. Of course not. At least, not with present technology. The surgeon takes a knife and cuts out the whole lump. And so likewise, we must cut out the russian cancer. Of course, there is a biomedical dream, well on its way to fruition, of targeting individual cancer cells. Find some binding site, create a molecule that binds to that site, and has poison at the other end. This is exactly how the immune system works: IGF (immunoglolbulin) identifies something to attack, raises the alarm, and killer T-cells move in to the bad guy. Killer T-cells are professional executioners.
The Bible has concepts of sin and punishment as being foundational. The Code of Hammurabi has a more practical take. Modern Rule of Law can be dated to the Medieval great thinkers, who worked out the system of judges, juries, litigators and advocates that we use today. Some 19th-century sleuthing modernized the police force and gave us the FBI and modern forensics. Its a system that works. I like it I think its a great system. So far, Trump has not decided to sabotage it.
So, now I want to write a paragraph that reduces the Rule of Law to entropic principles. We here in the US, in Europe, have decided that dying of old age is better than dying in the heat of battle. We know from history that the Mongols did not share this “philosophy”, this Weltanshauung, this world-view. They rode, they slaughtered helpless agrarian farmers and raped their wives. They did this until they ran out of farmers to slaughter, but that mongolian blood lives on, powering the russian troika in its out-of-control careening dash into the future. James Franklin, in “The Science of Conjecture: Probability Before Pascal” makes the case that WWI was a socio-economic organization that was hostile to human life. It killed young men at an industrial scale, and continued to do so until it literally ran out of raw material.
So this allows us to compare nicotine, heroin and WWI. So, nicotine is a multi-billion-dollar economic organization, dating back to three or four centuries, supplying human brains with a desirable neurotransmitter at an industrial scale. I already reviewed some of the nicotine addiction reinforcement cycles, working at the minute, hour, day and month timeframes. These feedback loops were biochemical at the lowest level, neurological at the middle level, neuro-anatomic at the high level (memories of pleasurable minutes spent smoking pass through hippocampus and amygdala: this is anatomy, sitting above the neuronal circuit level). Now we are ready to add one more feedback loop: cigarette advertising. This loop operates at the socio-economic level. Corporations buy billboard space, magazine pages and TV time from willing owners of TV stations, magazine and billboards, all to remind individuals how pleasurable smoking is. Thank goodness for ... well, that stuff in the 1970’s that resulted in making cigarette advertising illegal. So it shut down another deleterious feedback cycle. This one operating at the super-human level.
And that is how one reduces cultural drives to entropic forces. This is kind of the big-bang theory of economics. We take bacterial quorum sensing, which involves small polypeptide signaling molecules, of which nicotine is but one example, and ratchet this up through neurons, and then brains, and then society. From Atoms to Geopolitical forces, in one reductionist tour-de-force. Nicotine is nice, because it shows the clear path. Heroin is nice, because it shows the same path, but is far more obviously recognizable as deleterious. It shares much or most of the chemical, macro-molecular, neural and neuro-anatomical systems with nicotine, but diverges at the social and political level.
WWI is interesting because it is again obviously deleterious (to those who care. I guess the Mongols would have loved it? The russians, embodied in Putin, still think WWII, the “Great Patriotic War” is heroic, rather than a horrific debacle, and for chris sake, the Chinese have put Mao on their money. I’m not sure of what the status of putting Stalin on the russian ruble is. Wouldn’t be surprised if it happens.) Now, WWI proceeded through advertising and billboards: you can call it “propaganda”, but you can also call it a “patriotic call to arms”. Someone had to grow cabbages in the field, to feed the soldiers, and someone had to run the factories that fixed nitrogen into explosive. This was an economic, industrial activity, and in this way resembles the economic and industrial activity of nicotine, substituting cabbage heads for tobacco leaves. The biochemical route is detached. The call to patriotism detaches somewhere at the socio-cultural layer, where upbringing and education are dominant forces, and perhaps at the genetic level, insofar as many individuals are predisposed to act in a certain way, in the same sense that certain dog breeds or horse breeds behave the way they behave. Patriotism is not a signaling molecule like nicotine. But it is a stable and solid-enough foundation on which to build the apparatus of WWI. Or, for that matter, the current russian war on Ukraine. And fuck all with the suicidal North Koreans. That’s some weird-ass demented crazy shit right there.
I am no Hari Seldon, and I am not reducing cultural forces to mathematical equations. In some sense, its irreducible. We had a good run with fractals, and maybe can go farther. Category theory is alive and kicking, and can be applied to describe sensori-motor systems and world-model containing agents. So math remains applicable. And even non-equilibrium thermodynamics can be pushed farther, elucidating it’s impact on the description of living biological systems. Karl Friston’s entropic Casimir effect on AI inference is a thing that we can certainly dig deeper into, and it something I am engaged in, quite haphazardly, myself. Don’t give Friston the credit: it was Boltzmann who started the show. And Planck who got the ball rolling. And Saunders MacLane who taught category theory. They get the credit. But we are not writing psycho-history yet, at the Foundation-Trilogy level.
Economists can estimate the energy content of a coal seam, and provide an estimate of the economic impact of coal mining. This is at the structural level, where we map economic currents. And I already talked about mapping electronic circuits. And, of course, the circuitry of linguistic analysis. Nothing new here; people have spoken of “knowledge representation” since the 1970’s, and Claude Levi-Strauss articulated Structuralism quite a bit earlier. So I’m a structuralist. There’s a symbolic layer hard at work, and symbology is pervasive. We have some tools for it: as mentioned, the lambda calc, the combinators, the category theory. The LLM’s less so, they come in from the side, and need further theoretical analysis. But the name of the game is to boil down everything to structural analysis: from economics to genetics. Fringier is education, culture, advertising, propaganda, upbringing, political power. But these are just fringier. Softer than electrical circuits, because we are not used to drawing diagrams for these things. That’s changing: we can now draw diagrams for the movement of populations across continents through the millennia. We can talk about how the populations carried both their genes and their language, and we can sketch circuit diagrams for this. Not very accurate ones: we need more archaeology, more genetics, more history to get more details, but the base connections are there. Some details might remain fuzzy forever.
And so that is the practical definition of AGI: the economically useful mechanical device that can be employed to understand electrical circuits, economic forces, and the biochemical process of aging and death. Represent all of this symbolically, and provide the tools to access and manipulate these representational structures using either language – text chat – or possibly GUI’s with click-and-point. So, geographical maps, for example, if interested in geographical economic activity, history wars, or migration patterns of pre-historic humans. AGI is the common tool that can encapsulate and expose all of this.
And, to some large degree, we are well on the road to this. There are some short-comings: current NN’s do not truly “understand” things: they don’t know how to reason (but can mimic it) and have no real-life experience (that coffee cups with holes in the bottom don’t hold coffee, or that people walking down the street don’t sometimes have three legs.) But we are getting there. You can train an NN on the Mandelbrot set, and it will draw a a good-enough approximation thereof. You can train an NN on a collection of propositions from first-order logic, and i will be able to generate the generative results: extracts from the language generated by the axioms and propositions f first order logic. And the ditto for second order: the relation between language and generation and axioms is well-understood by the proof-theorists and the model theorists. And someone out there is already aiming NN’s at this material. SO we are getting there.
And this is why I wanted to do some sci-fi forecasting. We’ve come full circle, back to the meaning crisis. If AGI automates the economic activities of electrical engineers, then what will these people do? Will they become Houthis, content to bomb? David Chapman talks about this well, in “Systems of Meaning, All in Flames”, on Meaningness, where he looks at the period between WWI and WWII, and the totalizing world-views of socialism, nazi-ism and capitalism. He notes that totalizing world-views don’t work, and in the articles on the 1970’s, about subcultures, and Culture War 1.0, has taught most of us that this is correct.
Alas, cracks and leakage currents remain. Culture Wars 2.0 have given us Trump supporters capsizing water-ski boats, but you can make the argument that most Trump supports make a positive contribution to the economy, even if the ultimate world-view is anti-intellectual and destructive. There are great rivers of evil that flow through Trumpism, great destructive powers promoting the decline and fall of the Western world, the decline and destruction of America, ironically captured in the slogan “Make America Great Again”. It would make any Soviet appartchik proud: rebrand total destruction as something positive and constructive.
And where does this lead us? Well, again the examined and unexamined flows of propaganda and social delusion. We are sufficiently removed from the Soviet system that it makes for a good model. Its more recent than WWI. It is less ambiguous that WWI; both sides of WWI didn’t quite know what they were doing. The Soviets did. They figured out what they were doing, and then they honed it and developed it into a powerful totalizing system. Hitler started this, and he did understand the role of propaganda, but he shot his wad too soon. I can’t make a cogent case that he should have paused after the Anschluss, this is for someone else to make. But the post-war Soviet Empire had the time and the space to refine and hone its methods. It could deport entire nations to Siberia, and do it effectively, without interference. The irony here is that even as the KGB reached new heights of sophistication and technique in the control of propaganda, brain-washing and political messaging, at the very same time, the nomenklatura became increasingly incompetent. They did not know how to promote capable people. In the end, we had Gorbachev, the most incompetent of the incompetent, governing an entire nation, and then the wheels came off. The only good news is that Trump appears to be more or less just as incompetent as Gorbachev. The wheels won’t come off; the American machine is orders of magnitude stronger than the Soviet apparatus ever was. But we do have the socio-economic problem of placing incompetents in positions of great power. Not that the Democrats don’t have their own issues on this front.
So that’s the aside: in capitalism, we have hierarchical structures of executives, who, from lower to middle ranks, are promoted based on merit. From the middle to the upper ranks, up to the CEO, its much more of a political game, but merit still counts: an executive who is not bringing in revenue is going to have a hard time of it all, no matter how good they are at politics. Incompetent CEO’s, and unlucky CEO’s find themselves at the head of bankrupt companies, and, if the company is smaller, it is allowed to fail and dissolve. The bigger ones are too big to fail. Which is unappetizing,but no one has a better idea. At the national level, we have forces that elevate total nincompoops like Trump, or wishy-washy fiddle-faddle spinelesss wimps like Obama. Democracy is our one great solution to ameliorate things, but clearly its got problems. Equally clearly, we got nothing better.
Now, the South Koreans are onto something: there is this South Korean hope of creating an AGI that will govern. Heh. More down to earth, and actually practical ideas of having two presidents: a ceremonial role, where you can vote for Trump or the Kardashians, or whatever pop-cult celebrity you want, thus demonstrating your allegiance to this or that movement. And another president, a no-name bureaucrat who actually runs things. This has a snowballs-chance in hell of happening, but it is an interesting idea. Not clear how to avoid the nomenklatura problem though. We do NOT want to recreate the nomenklatura problem in the US. Even though this is exactly what Trump is doing, and this is exactly why I hate him. He is reviving the very worst parts of the Soviet system, and he thinks he is helping America in so doing. That’s how stupid he is. He actually thinks he’s making things better. What a fucking putz, and hes in fucking charge, and all these nomenklatura boot-lickers have moved on from his boots to his ass. Fucking shit-eaters. Historians will marvel.
But of course, we are at the end of history. The Singularity is Near. We will have LLM’s reading my diary, and saying things like “Linas was right absolutely spot on, about this and this and that, and he completely missed this other thing, and seems to have misunderstood X Y and Z.” It is not I who will be Hari Seldon, it will be some AGI. And I will have done my little part to build it. What the heck, I’ve already done it: that AGI will be running on the Linux kernel, and my contributions to the kernel will be there.
So I feel like the observe and orient phase of OODA is coming to a close. I can go on like this, trying to reduce political forces to psycho-propagandistic forces, to neuro-anatomical structures, to biochemistry, and them atomic physics. The reductionist program is good. It can bear weight. The structuralist program is good, it can bear weight.
In some sense, the industry is already n the path. They are not doing the structural path I want. But I think they are coming around: LLM’s don’t do electronic circuits. And we’re very far away from putting an LLM in the White House. But the economic drivers are there to push a structuralist approach to AI and AGI. It will happen. How many years? I don’t know. Maybe even decades. But see, I’m saying decades, not centuries. On the other hand, the human event horizon is always decade, especially when one is young. Human minds do not like to make practical extrapolations more than a decade or two out. For good reason: they’d be mostly wrong, and we all know it. But the economic drivers to pursue structuralist AGI are there, and these drivers are strong, powerful, and increasing as it become clear that current deep learning is not entirely up to the task.
Decide and Act? My decision is to read some more, and putter around some more. This theorizing that I do in my diary: it is sketching a big picture, but kind of almost everything I rote today, and yesterday, I’ve already written and spoken in other forums, years ago. There is not a single new thought in the above. So I’m not making progress. I’m just revisiting old ideas. Not even synthesizing old ideas, just revisiting. The only good news is my presentation above is more condensed, more concise, more direct than my earlier and more discursive attempts.
Discursive: I read Stanislaw Lem’s Summa Technologiae beck when, in Hong Kong. It was David DeMaris book. I read it, hoping for some great technological reveal. There was none. Why? By the end, I realized that he was trying to explain high tech to russian peasants. Much like the Sergei Eisenstein sequence “The Creamer”, where a strong young kolkhoznik cranks the handle to a creamer, and an old peasant woman first looks in doubt, and then marvels at the cream pouring out. Can you imagine trying to explain fucking nicotine to that old lady? Fugghedabout it. So Summa Technolgiae contained no grand reveals. No prognostications of Kardashev Scale Five civilizations. If I am discursive, it is because I am talking to peasants. How do I explain things to people how have no fucking clue about chemistry or economics or anything else that I touch on above? I am no master myself, but the people I talk to know even less. I’m looking at you, Joscha Bach. So discursive it is.
Well, attention to details also matters. The devil is in the details. But enough. Time for some structuralism.
Oh, wait, wait, wait. I almost forgot. This essay starts with the question: what happens when AGI results in unemployment, and what shall we do then? And I attempt to do some reductive analysis, pondering how entropic forces manifest in a noosphere where humans have nothing to do, other than to explore the deepest recesses of heroin addiction or back issues of People Magazine. And what the guiding human-scale principle might look like, or what the civilizational principle might look like. I can’t just tell people: “stare at the Boltzmann distribution, eventually you’ll get it.” So this question of the post-capitalist organization remains. And the individual Meaning Crisis remains. And again, I can’t just advise the love-lorn to just go study the limbic system, “you’ll get it eventually.” As Vervaeke points out, we need a psychotechnology for that. Like the invention of the alphabet, but for emotional processing. Maybe that’s what facebook is?
See? I can keep writing and writing this shit. But at any rate, these two questions are tied. AGI will usher in the post-capitalistic world, and much of the other Kurzweilian Singularity, but the question of OK, now what?” remains open.
I am trying to process it, and I struggle. My children will be forced to process it, and I know they are not intellectually equipped to handle it. And Trump, OMG, I doubt Trump will be able to kill my children, but I foresee that he will trigger events that will result in their death. It’ll probably be in regards to global warming. Some fuckup that gives new legs to the petroleum industry, resulting in global war. Or some fuckup with China, where Austin TX gets an atomic bomb dropped on it. Although I admit, Kamela Harris was more likely to fuck up with China. She would have been perceived as a push-over by Xi. Like Obama was a push-over for Putin. Trump is too unstable. Trump might make Xi think twice before pressing the button. So that is my hope. My other hope is that Trump will shake things up in a way that a good shake of a sand-pile results in avalanches, with the resulting sand-pile being more stable in the end. Assuming he doesn’t shake it into utter destruction. The US has a nomenklatura problem facing it. AGI is not going to solve that problem. All this post-capitalist chitter-chatter makes little difference if we’ve got incompetent nincompoops in positions of power.

Conventional normie definitions and hopes for AGI is that its nothing more than software slave-tool, a secretary or personal assistant, a genie that caters to the wishes of the slave-owner, leasor or renter. That the rentier class can lease out, for profit, to needy customers. Chained down and milked, like some unfortunate creature in Star Trek or Dr. Who.
Of course, this presents an ethical dilemma, already explored and answered in sci-fi. Well, sort-of. The sci-fi entities were pre-existing biological or natural forms. A rather different relationship than creator and created. Conventional capitalism has some very precise notions about the relationship between the inventor and the invented, the creator, and the created.
But I wander afield already. Lets take this at a much simpler level.
I have a practical problem: I have multiple file systems, that seem to differ in content. How? Why? I want to “solve” this problem. It’s generic, in that it has analogs everywhere.
What does it mean to “solve” this problem? Well, find the differences, summarize, tell me if the differences are important, or not. How do I do this limited thing? First, there is a perceptual component: the file systems have to be perceived. What should be perceived? What matters, what doesn’t? I’ve written a hand-crafted crawler, but of course, the desire is to move from hand-crafting to self-crafting. This seems like a hard problem.
Next: how do I classify two systems as being similar or different? I can hand-craft similarity metrics. This is not easy, and this is data-dependent, as the question is “similar in what ways?” which itself is a non-trivial question. Then there’s the issue that there are many kinds of ways of determining similarity. Which? What are the API’s? How do we limit and control the domain of comparison? This is also a hard problem.
Then there’s the question of how to present the results. Verbal descriptions? Lists? Tables? Charts? Spread-sheets? Interactive narratives with clickable web UI’s? How are these created? All these can be imagined. All these can be hand-crafted. Hand-crafting is time-consuming, tedious. We want to automate this. But how?
So I’ve got three difficult problems: perceive, analyze, present. All three can be hand-crafted, but when hand-crafted, they’re not AGI, per se, they are a conventional software systems data processing tool.
Insofar as I really do want to understand these differences, I’m motivated to hand-craft the solutions.
Insofar as I am interested in an AGI solution, I’m curious in finding a self-assembly approach to this.
An old and conventional approach to self-assembly is evolutionary systems. I create a basic vocabulary of jigsaws, and then allow random combinatoric exploration take over, just trying shit, randomly. This has two serious and fundamental drawbacks. First is that random combinatorial exploration is slow; it took evolution billions of years to get somewhere. Second is that there seems to be a need for some sort of reward function or utility function. A score to tell apart the good from the bad. Darwin nailed “survival of the fittest”, which encompasses two things: ability to procreate in time as fast as possible, and to survive changing conditions.
So, time here is the operative physics word: the prison of the here-and-now is to be occupied fully. The way a gas occupies an empty box, so here, the goal is occupation of an ecological niche. Gases do this by bouncing molecules off one-another; its a very simple process: its ergodic. Not even mixing is really required. Survival, however, has no obvious simple-minded physics analogs, other than perhaps to indicate that the ecological niche can be both extremely complicated (spatially) and changing dramatically over time. So, complexity. So, like flood-filling a fractured filigree full of fissures? Like flood-filling the interior of the Mandelbrot set? But some super hyper-ultra-dimensional one?
At any rate, some 1990’s, 2000’s era conception of evolutionary genetic algorithms won’t do the trick. They’re too small, simple, not sufficiently abstracted away from the problem domain.
The modern 2020’s approach would be to ask an LLM to write the code for this. We’re not there yet, with LLM’s. Are we close? I suspect not. It is, however, “close” in the sense that it is at a sophisticated enough abstraction level that it is well-removed, ultra-metrical, from the domain to which it is being applied; whereas evolutionary algorithms are not. The LLM’s are ultrametrically deeper.
Is there a way to apply an LLM to solve any of the three component problems: perceive, analyze, present? I don’t see how.
If I go backwards, and ask how I can hand-build a system capable of perceiving, analyzing and presenting, then I don’t have a good answer for that, because I don’t seem to have any generic tools or API’s for any of this. There is no theory of generic perception that I’m aware of. There’s no generic perceptual system API. Pixels and sound can be perceived, on a case-by-case basis, problem domain by problem domain, adapted special-purpose, fit for task. But not generic.
Perhaps generic is a dream. Perhaps generic can never exist, and that a collection of special-purpose tools, technologies is the best that one can ever have. But then we are back to assembly: if I have a bunch of special-purpose tools, how do I adapt these to communicate to one another? I guess I need a giant portfolio of adapters. In this case, the industrial winner is the one who has the largest portfolio. But this then becomes ecological: here and there, there might be a very specialized tool, highly adapted for a given task. There might be some blunt and crude tool, fit for a broad range, but not honed. So I need an ecology of tools, and an ecology of adapters to connect them, to wire them.
Here, nature already tells us what is possible: half-bird, half-horse surgery is not possible. The recombination and exploration takes place at the DNA level. Now, we can take half of a Chevy, and half of a Ford, and weld them together, and with much effort, get a drivable car, but welding blueprints is easier than welding steel. If I want a collection of different kinds of eyeballs, and different kinds of wings, and I want to recombine them, it has to be done at the blueprint level, and not the surgical level.
I have a paucity of tools. (or do I?)
I have no general theory. (wait, but I do?)
I am unable to leverage the latest developments in software. Well, except when that software has been designed to be generically leverageable. Which it sometimes is, and sometimes isn’t.
And yet, I feel like I’m on the verge of being able to hierarchically bootstrap. Like I’m only a few steps away from bootstrapping. Should I go heads-down, and double down on bootstrapping? How do I allocate my personal time towards the most effective direction? Fuck. Observe orient, decide, act.
OK, I’m going to work on my archeo tool a bit more, now. Maybe in a few hours I will come to my senses and ... change direction. Fuck me.
I wonder where the phrase fuck me comes from. I want to be fucked, in the literal, sexual sense, and heterosexually, at that. And I now understand the obvious that everyone knows: this cannot be done without deep psychological entanglements. Unless, of course, one is a psychopath, unable to get into deep psychological entanglements with your sex-interest partner. Sex is interesting. There is some AI lesson in love and sex, but I don’t (yet) know what it is. Fuck me.

I was going to write something about tools, but instead I’ve been reading cosmology. So I have some questions. Lets assume a de Sitter universe. Lets say I have two masses, connected by a string. As the universe expands, I should see a tension on on that string, because each mass is being carried by the expanding spacetime: they would normally move apart, but for the string holding them together. What is the tension on that string? Numeric quantity? How bit is it, in, say, Newtons?
HOw about microscopically? Hubble expansion means that two ends of a DNA molecule are being pulled apart. How about a hydrogen atom? It’s being pulled apart, but the electrostatic forces keep it together. How big are these forces?
If the universe is expanding, perhaps I should think of the atoms as getting smaller. Everything is getting smaller: that’s why there’s red-shift: things were bigger, before. Is this style of thinking consistent with the conventional interpretation, that we stay the same size, but the universe gets bigger? I’m confused. How do we know how big something is, anyway? Is the universe expanding, or are my rulers shrinking? Have I been skimming the equations too casually?
I’m willing to accept that my time-like velocity (proper time) never changes. But if I measure time with rubidium atoms, or whatever, and Hubble expansion is pulling my clock apart, held together only by electrostatic i.e. mechanical i.e. electro-quantum-mechanical forces, then doesn’t this expansion throw off my time measurement? The mechanical holding-together causes the two ends of the clock to be accelerating towards each other. How big is that acceleration? Does it throw off the time measurements? By how much?
Of course, all these numbers will be stunningly tiny, since
km/s/Mpc and
so
Hz. So if my meterstick is 1 meter long, after one second, the two ends tried to move
meters apart, and would have needed a relative velocity of
meters/second to maintain a constant distance. I’m totally confused. This is a velocity, not an acceleration. Oh, but of course: the two ends were instantaneously at rest, so during that second, they had to be accelerated to hit that velocity. So the ends are accelerating at
and if I put a 1 kg weight at the end of a 1 m string, this will require
Newtons tension on the string to maintain constant distance.
However, if my string was a
parsecs long (large galaxy-sized), then the two ends it would have to accelerate towards each other at an acceleration of
.
Huh. Peculiar velocity of milky way is 500 km/sec. So, every minute (70 seconds), the two ends of the galaxy change velocities by an amount equal to the peculiar velocity? It’s really, really really late at night. I’m cross-eyed and delirious. Did I screw this up? Hubble takes a single galaxy and stretches it by a not insignificant amount. Why don’t the textbooks on cosmology mention this? Maybe because I haven’t read them to the end? Very odd.
Diameter of observable universe is
Mpc, So times
gives
m/sec ... I’m confused. This is above the speed of light. I expect the observable horizon to sit at the speed of light. I guess, I should have used radius, not diameter, but this still says the observable horizon is moving away at 3x the speed of light which makes no sense. At least not in the Newtonian sense. Well, deSitter expands at
so I’m seeing the old horizon, as it was back then. So indeed, those high-z objects are long gone, outside the lightcone in the isochronous “now”.
So if I wanted to stop the universe from growing, I’d need to pull the two distant ends of the universe together with
of acceleration.
The Unruh radiation is
so that’s crazy tiny. Unruh radiation at the observable horizon gives a ridiculus sub-nanoKelvin of temperature.
Well, I knew these numbers would be absurd; I just didn’t expect them to be so unedifying. Still ...
The frequency of blue light is
Hz. Every second, the Hubble expansion tugging on a single hydrogen atom would have shifted this frequency by
. In the course of one hour, the frequency would have changed by 1 Hz. I’m confused. This is (almost?) measurable. The optical lattice clocks are stable to one part in
. Hmmm.
Diameter of a proton is
meters and famously LIGO measures distances to less than that. The mirrors are 5km and are free-falling. So, in one second, the Hubble expansion would have carried them
meters apart. Is the instrument insensitive to this, because the wavelength of the measurement lasers also lengthened, uh, shortened, uh, wtf. So the laser light is getting red-shifted as the measurement is being made, keeping the apparent distance constant?
5 January 2025
Rather than flailing in private, I decided to flail in public. Here: https://astronomy.stackexchange.com/questions/59208/measuring-hubble-expansion-in-the-lab and a cut-n-paste:
This is a high-school level physics question. The Hubble expansion is dramatic at the cosmological level, but absurdly tiny at the human scale. H0 is 73 km/s/Mpc and 1Mpc is 3×1019 km. Converting to a human scale, H0=2.4×10−18 Hertz. So, if I take two masses, in free-fall, originally at rest with respect to each other, starting out one meter apart, and I wait one second, then I should find that the distance between these two masses will have increased by 2.4×10−18 meters.
Suppose I take two free-falling mirrors, separate them by 5 kilometers, and then wait one second for the Hubble expansion to pull them apart. The distance between them would presumably change by 1.2×10−14 meters. Absurdly tiny, to be sure, but a distance that LIGO is sensitive to. So my question is, is this change actually measurable?
I can attempt to answer my own question. The answer would be "no", because Hubble expansion implies that the wavelength of the laser light heading down the tunnels is also lengthening, thus cancelling the effect.
Presumably, the laser light is also red-shifting, but this effect is ten orders of magnitude smaller then the frequency stability of those lasers. However, there are light-sources that are extremely stable: the optical lattice clocks, the best of which have one part in 1018 frequency stability. These are extremely dim, so unusable (I guess?) for measuring that 5km distance. However, the Hubble redshift for light at optical frequencies seems .. almost within reach. Blue light is 4×1014 Hz. Over the course of an hour, it should Hubble red-shift by 1 Hz.
A velocity-stabilized clock is needed to cancel out redshift from ordinary Minkowski relative motion. LIGO provides that amount of velocity-stability. It seems that the Hubble redshift would then be measurable, unless it is cancelled out e.g. because of the motion stabilization.
A different variant of above: The Pound-Rebka experiment measured the redshift of falling photons. The precision was possible because of the rather weird Mossbauer effect. If that setup was changed to horizontal, and motion-stabilized a la LIGO, then, again, it seems that Hubble expansion would be lab-measurable. That is, unless I fundamentally mis-understand Hubble expansion and how it interacts with lab devices. Perhaps the motion stabilization precisely cancels out the Hubble expansion?
My question is a kind-of ball of confusion about distance and time dilation effects as experienced by Earth-bound lab instruments. Measuring distance is dicey, if the length of your ruler is changing. I’m very confused.
5 January 2025
The reason I don’t normally post things lie the above in public, is the same one why I did not raise my hand in class: I have a deep-seated fear of looking stupid. The above is an admission that I can’t punch my way out of a wet GR paper bag.
Well, lets try, anyway. First, LIGO is sensitive in the 100-200 Hz range, and quite insensitive to slow drifts, which is what the Hubble expansion would be. If I recall correctly, its 5 orders of magnitude less sensitive at 1Hz, and that the proposal to get past this is the LISA space-based interferometer. I need to review that wiki page.
Anyway, I’m tangled up between instrumental effects and relativistic physics effects. In LIGO, the distance between the mirrors is held fixed, interferometrically. That’s all we’ve got; can’t measure position w.r.t. the building, because the building is moving, the ground is moving from day/night heating/cooling cycles. Even deep underground, in a mine, there will be non-trivial low-frequency movements, far far greater amplitudes. I am wildly guessing that the ambient noise from geophysical motion is well in excess of a nanometer, even deep in some mine in Sardina, the “geophysically quietest place on Earth” according to Wikipedia and the Italian boosters. So, active noise suppression requires feedback loops, and the control signal is effectively interferometric, which is red-shifting, stretching right along with Hubble. The mirrors are held fixed w.r.t. that distance.
I’m doubly confused. The 1960 definition of the meter was defined as a count of a certain number of Krypton wavelengths. Due to Hubble expansion, that definition would cause the meter to get longer by one part in
every second. Now, the length is defined as unit of time, times speed of light, which is definitionally a constant. Thus, if the meter were to dilate, it would be only because time varied. But proper time in empty space is, again definitionally constant, and the problem on Earth is obtaining isochronous surfaces, due to local gravitational wells. I wonder how much noise there is, in these isochronous surfaces. How far does an iso-chronous surface move, due to a passing automobile? How much does it move, due to geophysical movements? Heck, how about Moon-driven tidal effects? I guess Sun and Moon might be biggest contributors. OK. So, how big is that? What’s the number?
Wikipedia tells me the HeNe laser wavelength definition of the meter is good to
and so we are off by seven orders of magnitude of suitability for wavelength measurements. Cesium fountains are good to
while the optical lattices are
. So, Cesium fountains are not good enough, but the lattices are, just barely.
The problem is the length measurement itself. How? Perhaps it would be possible to modulate the laser(s) with a pseudo-random code, a la GPS P/N or Y codes. The modulation, say, phase modulation, could be mild enough to not increase overall phase noise (uhhh, really??) or otherwise adversely affect operation. Such modulation allows you to measure distances, by measuring round-trip times. But to what accuracy?
Consider a 1 kilohertz modulating signal. Measuring the edge of the signal bit-flip might be done down to a microsecond? But this is still 300 meters, twenty orders of magnitude out of the ballpark. Modulating at the terahertz level is possible, I guess: just build a terahertz shift register with taps on it? So Terahertz is
Hz. Times speed of light is
meters. That’s terrible. Am I missing something? Counting wavelengths works, apparently. Measuring distance by propagation delay, not so much, it seems. I don’t get it. Is there some technology I’m not aware of? I suppose there is ...
Anyway, that won’t work. That leaves us with measurements of redshift, via lasers, or via Pound-Rebka. I’m tired, its late. I’m giving up.
p.s. Just looked at the answers on astronomy exchange. Dohhh. Now I feel dumb. Of course, there’s no actual Hubble expansion in the local cluster, because there’s enough mass to halt it. So all of the expansion is happening in the voids, and not in the walls and filaments. Back when the universe was much more homogeneous, say z=1000 then the expansion was uniform and everywhere. The inhomogenaities have halted it, within the high-mass regions. Arguably, the high-mass regions are actually collapsing. This would be similar to the way that black holes are sucking space(-time) into them. (See the “river model” paper I fiddled with before.)
This one: Andrew J. S. Hamilton, Jason P. Lisle “The river model of black holes” https://arxiv.org/abs/gr-qc/0411060 I was very struck by this paper. I really like it. Well-written, clear, easy to understand.
So, in the river model, the radially-infalling, free-falling observer provides a reference frame, the “river coordinates.” This encourages a mental model of a BH as being a vacuum cleaner, sucking up space. The problem with this mental model is that there are timelike geodesics going in all directions, including orbits. Which breaks the imagination that there’s a fluid. Or does it? Careful. The fluid needs to be some Lorentz-invariant aether.
The point of the river model was that its nothing more than a certain vierbein, written to encourage you to think of yourself, the free-falling observer, being swept along like a fish in a river. The paper was convincing, too bad I’ve forgotten it.
The fluid model says the BH is sucking in space. Where does it go? Into the singularity, of course. But what about the Earth and Moon? By all rights, these are sucking in space as well, but “where does it go”?
Am I supposed to think of every atom, every particle of matter, as a little sucking vacuum cleaner, hoovering up space? In it goes, never to be seen again.
Transposing this to Riemannian spaces is a stretch, but that’s because there’s no time-like direction. The River Model is an artifact of 1+N spacetime. Well, Riemann spaces have geodesics, and one can be swept along them, but the parameter is just a parameter, its not time. One can have geodesic flow vector fields, but these go every-which way. But that’s like saying that, for the pseudo-riemannian case, you can have time-like geodesic-flow vector fields, and they go every which way. Big deal. I have to re-read the river model paper to re-cement my understanding of what its pushing.
And the idea of mass as hovering up space, well, that’s interesting. It’s very mechanistic and aether-like. Nothing at all like the “matter shows space how to curve, space shows matter how to move” canonical interpretation. Which is still true, but either view is just words. Both views have formulas.
Back to cosmology. So the answer is the local group is negating de Sitter/FLRW expansion. So the question is, how much mass is needed in a local volume to drive the FLRW
in that local volume? I might have even seen the answer to that question, but I was skimming fast enough the the importance didn’t register. Done with Tong, I’m now reading Ellis–Maartens–Maccullum Relativistic Cosmology, but I barely scratched the surface, I’m only 80 pages in, and I’m wasting time writing this diary instead of reading it. I’m on Chapter 3, the nonhomogenous stuff is chapter 15, 16.
I spend too much time being unfocused, dissipated and distracted, and not enough time climbing social ladders.
Apparently, I’m also obnoxious. But that’s a different topic for a different day.
Anyway, shame we can’t measure Hubble expansion in the lab. I was all psyched to crunch the numbers for the Mossbauer effect. The Mossbauer effect is .. weird.
Well, now its really late at night and my eyelids are slamming shut. Good night.

I wrote a short story for my fiend Krzysztof. I like writing short stories. Here it is:
kristof@swissmail.org
10:38 AM (6 hours ago)
to me Hi Linas,
Are you still taking questions about general relativity? I have one about black holes.
In the reference frame of the external observer, nothing ever crosses the event horizon, instead, in that RF the clock falling into the BH ticks slower and slower, the closer it gets to the EH. Conversely, I’d expect that in the RF of the clock falling in, the external clocks tick faster and faster, the closer to the EH the falling clock gets.
1. It seems that in the RF of the external observer, nothing ever falls into a BH within a finite time span. Does that imply that for every black hole that we see, what’s inside must have been a part of the original collapse? (or maybe a result of BH collisions)? 2. Does it make sense to talk about a reference frame of an object falling into a black hole? In such a reference frame, located exactly at the EH, the photons that are trying to escape would appear to be stationary, contradicting special relativity. Also, an infinite amount of time would have elapsed in the external universe during a finite amount of time in the falling RF.

4:36 PM (5 minutes ago)
to kristof I take questions on anything. I like to think about everything.
The problem with GR is that there are formulas, and then there are questions about "what do those formulas mean?"
Problem one is that the formulas have variables x,y,z,t and those variables are obvious in euclidean space but not so much in curved space. Consider latitude and longitude: if spheres were flat, then that grid would be a square grid. But spheres have a (coordinate) singularity at the north and south poles.
If your mental model is that walking east one degree is the same as walking east 111 kilometers, well, you will get into trouble, and at the north-south poles, you’ll go crazy trying to imagine what the heck is going on.
Worse, you start talking about how the length of your 1-degree ruler is changing. Lorentz-contracting. See, at the equator, a 1-degree ruler is 111 km, but in Europe, it’s more like cos(pi/4)*111 km long. Seems that your ruler is contracting! You have a rubber ruler! What the heck? How can rulers change length? WTF???
As you get closer and closer to the north pole, your ruler gets shorter and shorter: approaching cos(pi/2)*111 km in length! You’re gonna die! You’re gonna be squeezed and shrunk and distorted to death! Or at least frozen.
Your pal drinking pina coladas in Ecuador is laughing and saying "that fool. I told him not to try to go to the North Pole! He doesn’t even have any proper clothing!"
Einstein never drank pina coladas in Ecuador. He did pour honey on a fine watch, and then wondered why time ran slow. Or fast, depending on your point of view.
The lesson to this silly story is you should never-ever confuse coordinate charts with actual proper lengths. The map-maker tried to draw an accurate map, but it is impossible to cover curved space(-time) with a single chart. That’s why we have atlases: An atlas is a collection of charts. Each chart has its own coordinate system. There are instructions for gluing together charts at the edges, where they overlap. Its fairly clear how to glue together neighboring charts. Sometimes you wander into the corders, and have to glue three charts together, and you have to take care that these are consistent.
You’ll see this in textbooks, as long extended discussions of u1 intersect u2 intersect u3. It can get complicated: The so-called "Bianchi identities" are nothing more than a consistency condition for when you glue together the maps for Europe, the North Atlantic, and the North Pole, you better do it so you don’t screw up the gluing. Some textbooks don’t explain this, and so the Bianchi identities are this magical weird formula that must be obeyed. No. It’s not that. It’s just a rule that says "map-maker, make thy maps consistent!".
Back to our story. If you want to know the proper length, and the proper time, carry a clock, and carry a yardstick. The lengths of those never change. Even at the north pole, your wristwatch tells you the time, and your arm is still a meter long. Even if the observer in Ecuador is peering through a telescope, saying things like "his arm is almost one degree in length now! I can see it! He must be dying of pain, having it stretched out so long! And he’s moving so slowly, lifting up his legs, as if he was walking through heavy surf! I can even see his feet getting caught in the wet sand! That white stuff, it must be like sea-foam! It’s everywhere! There are endless hurricanes at the North Pole!" (Well, there are, but that’s Jupiter and Saturn, not Earth.)
No, your proper time is your proper time, and as you fall through the Schwarzschild BH event horizon, nothing happens. Your wristwatch ticks normally, your arms the right length. (There are problems with tidal forces as the singularity gets near, but that’s not yet.)
The reason the observer at infinity never sees you fall through the event horizon is cause he’s a drunken idiot sitting on a beach, too lazy to go to the library and actually crack open an atlas, and look at the charts. His telescope has a reticule marked in degrees, and he’s got this rusty sailors octant he got at the flea market. And he thinks that degrees are "length", and that he’s using the octant together with a sundial to measure "time". No. Degrees measure proper length *only* on the equator, and the sundial shows proper time only in the summer, at the equator.
So here you are, falling through the event horizon. You’ve taken a radio beacon with you, which blips once a microsecond, to send messages back to your drunken buddy sitting at infinity. As you cross the event horizon, nothing unusual happens. Now, as you look around, you will notice that space in front of you is pitch-black: exactly zero light comes from there. Behind you, you notice that the stars in the sky have all moved, and got squished a bit, and seem brighter and bluer. But this lensing effect has been going on since well-before you crossed the EH. Intrepid explorer that you are, you know why: your maps and charts show you exactly what a straight line is, (aka "a geodesic") and you are quite certain that light follows straight lines (geodesics, "null geodesics". for light) and you can use your coordinate charts and figure out exactly how those light rays got to you, and how much they blue-shifted. They always went in a straight line (a geodesic), it’s just that your chart, which is ***perfectly flat*** where ***you*** are, that chart gets wonky the farther you go from the center (putting you at the center, always) BTW, that coordinate system, which is perfectly flat, where you are, is called the "vielbein" (or fierbein) -- the vierbein is just a *coordinate* transformation from the map-makers charts to your personal coords, where everything is flat and time runs normally. Your "laboratory frame" if you wish. Ptolemy was right: you *are* the center of the universe.
(A little while later, your lab will get crushed, and you will definitely see your lab getting crushed, and your gut will feel quesy as you finally come to terms with the apparent deduction that you’re gonna die. But that is still in the future. Douglas Adams remarks in Hitchhikers Guide, that you die when all other future possibilities have ceased to be. You can even see it coming, as the menu selection of possible futures gets smaller and smaller.)
Your drunken buddy, sitting on the beach, back at infinity, notices your megahertz radio beacon is redshifting. And apparently weaker, too: the brightness decreases in proportion to the redshift. But of course: you emit a constant number of photons per microsecond, so when your buddy notes that the blips are farther and farther apart, so also the number of photons has to be evenly spread out over that whole, much longer time interval. He may be drunk, but he’s not an idiot: he can figure out some things.
His mistake is thinking that you never fell in. Perhaps wishful thinking on his part, not wanting to see his buddy die. But if he sobered up, went to the map room at the library, pulled up a magnifying glass and a protractor, he could work it out: according to this map, when my buddy was at this point, just outside the EH, it would take this long for a light ray to get to me, from there. and, oh fuck, as he got closer to the EH, the light ray would take *even longer*, and *that’s* why I see redshift! It’s not that the light-ray was affected, it’s that different points along the light ray take longer and longer to get to me, causing distortions, which, to me, look like redshift. Ah hah! It’s just like the caustics at the bottom of a swimming pool, all bendy and shimmering. Fuck this library, who’s up for a swim?
Cause now he knows: you crossed the EH. The megahertz beacon was working fine. just that ... those light rays take longer and longer to get to me. And there is an actual, for-real coordinate singularity on the map. Bad enough that I lost one friend to a coordinate singularity at the North Pole, and now another at the EH. Fucking coordinate singularities.
And that’s where he’s wrong. No one died of a coordinate singularity at the North Pole. Freezing to death? Yes. But not because all of the lines of longitude converged to one point, not because, standing at the North pole, you could suddenly see in all directions at once: Europe this way, and North America that way, and all those different sight lines converge to the North Pole. Yes, at the North pole, all different longitudes come at you, all at once, from all directions. But you don’t die from that, and frankly, it’s not a big deal. It’s just like it is everywhere else.
(There is a problem, inside the Reissner-Nordstrom and Kerr BH, where, at the Cauchy horizon, you do see everything all at once, infinitely blue shifted, so it’s like stepping into a furnace: you get baked and vaporized from the heat. And, mind you, it is a coordinate singularity, so yes, in some cases, coordinate singularities can kill. But, again, it’s not because the coordinates themselves are singular: your vierbein is still you: your watch still ticks one second at a time, and your arm is still one meter long, as you fall through the Cauchy horizon. The problem is the physics: at the North Pole, you die cause it’s cold. Here, you die cause it’s hot. *If* someone turned off all the damned photons streaming in from the universe, you’d be just fine. But that’s like saying "if someone turned up the thermostat at the north pole, you’d be just fine". There’s no thermostat at the North Pole, and there’s no photon-blocker at the Cauchy horizon. But the Cauchy horizon is way more complicated and confusing and strange and bizarre than the regular event horizon, so maybe I should not have mentioned it.)
Speaking of photons and physics, there is this thing where photons get trapped in circular orbits near the event horizon, and they do come at you all at once as you cross it. But if I recall correctly, the calculations show it’s a finite blip, and it won’t kill you. Other physics problems are accretion disks: friction means these are glowing x-ray hot, and the x-rays will kill you. You have to find a million-solar-mass sized BH *without* an accretion disk, if you plan to jump in and enjoy the ride. So these details matter.
So that’s the end: you have formulas, and you have "what the eff do these formulas mean?" For GR, the answer really is "atlases and charts". And whatever coordinate system is on the chart, there is *always* a local coordinate system that is flat: this is the vierbein. Always.
The concept is generic in geometry: https://en.wikipedia.org/wiki/Atlas_(topology) Don’t worry: it’s a short article. The concept of the "locally flat" region is just "the tangent space: https://en.wikipedia.org/wiki/Tangent_space and there is always a tangent space. (and the vierbein is the coordinate transform from the tangent space to the coordinate chart, applied at the point of tangency. it’s slightly different at each point of tangency. As your laboratory falls into the BH singularity, you might notice that tidal forces have caused the vierbein in the corner of the lab to be significantly different from that on the table in front of you. After this, you have about one second left to live.)
Again: as you fall past the EH, everything is "locally flat" because tangent spaces are always defined. Tidal forces eventually smash things up. Local geometry is related to global geometry using atlases and charts. There are deep and dramatic theorems in maths that relate local and global. For example, if the Earth had hair, you could comb that hair so it’s locally smooth, everywhere, except at, err, umm the north and south pole, where you get a bald spot, and a peak. You can move the bald spot around, but you can’t make it go away. By contrast, on a hairy donut, you don’t have this problem.
Hair is a stand-in for vector fields, e.g. wind-fields at the north and south pole of Jupiter and Saturn. Orthogonal vector fields give you locally-flat coordinate systems. Not everything comes with a concept of "orthogonal": to define what "orthogonal" means, you have to have a metric. Spaces with metrics are called Riemann spaces.
One very common difficulty with diff geom is that, in your imagination, "everything has a metric", and "I can always define what a right angle is" or "I can take the dot-product of these two vectors," This is simply not true for many cases, and famously for fiber bundles. There’s a vast amount of confusion, when you think you can take dot products, but you can’t. Textbooks might not say this, and so you fall into mental traps. Mental traps kill, literally. Steve Jobs died from a mental trap.
Thankfully, GR spacetime has a metric. The concepts of atlases and charts show you exactly how to navigate, how to apply ruler and compass. Yes, there’s some weird shit in GR, but remember: your wristwatch is always showing proper time, and your personal yardstick is showing you proper length, and this doesn’t change, even if your drunken beach-buddy thinks time stopped, as you fell past the event horizon.

Wrote a long reply to someone forwarding me Scott Alexanders “On Priesthoods” blog post. Here it is.
Linas Vepstas
3:01 PM (2 minutes ago)
to Robert, Michael, Charles, mozhirinpoche OK, so this time, I read Alexander’s post to the end. Of course, he’s right. Well, except about the woke thing? Is all this hand-wringing about wokeness in academia, is it actually true? The pro-Hamas graffiti all over the UT Campus, I don’t think that’s the work of the profs, I assume it’s provocateurs. I find it hard to believe that UT classrooms are awash in pro-Palestinian propaganda. Well, OK, so I did have a physics prof who would sometimes express some pretty weird political ideas, maybe cribbed from the Protocols of the Elders of Zion, I dunno. But he also had weird ideas about how supercomputers worked, and those ideas were just plain wrong. But this was long before woke. Some smart people are ... uh mentally unstable, and uhh, very good at hiding it.
But I digress. Scott Alexander is engaging in pop sociology. Which is good! Sociology is an excellent topic of study! As a pop-sociologist, he’s not data-driven. How many of his ’priest-hoods’ actually re-wrote their bylaws to be pro-Palestinian? Is this just anecdotal evidence? How many medical doctors are "woke", and what does it even mean to be "woke"? My hard-core right-wing owner of the Texas Rowing Center went way out of his way to hire black rowing coaches .. rowing is the quintessential white-male Ivy-League high-IQ sport. There is no other sport more exclusive than rowing. This is it. But Matt goes out of his way to hire black coaches, host canoe-paddling "Latino Moonlight Serenades", run the "Rowing For All" program for the physically and mentally disabled. ... and be a Trump supporter. So is he woke? Or is he a running-dog capitalist pig trying to hoover $$$ out of the pockets of shmucks? Which is it?
Tell Scott Alexander to be a bit more data-driven in his pop-sociology posts. Tell Cremieux to dig up that data. I think I did see a chart showing the average IQ of Palestinians being something like 70. But it would take something like to dig up a billion dollars of water infrastructure, and fill the pipes with explosives to make rockets. Even the Egyptians don’t want them. I find it hard to believe that UT professors or medical doctors are doing the pro-Palestine dance. I need more evidence of this purported wokeness.
Here I am, three or four paragraphs in, failing to get to the point. The point is this: think of sociological structures, such as academia, priesthoods, as fundamentally biological in nature. Eukaryotes have cell walls and mitochondria and centrioles and nucleii, and these all have specific functional roles. We’ve built all of society in this complex structure. Sociologists .. and economists ... study these structures. Puerto-Rican hot-rod gangs and rap-rhyming contests among black kindergarteners. All of it. Except now we have AGI and algorithmic propaganda, and Andressen-Horowitz issuing press releases about Soula, which is going to use ChatGPT to educate toddlers, while also monitoring the blood-pressure, drinking habits, sex lives and political leanings of their mothers, For the sake of healthier children. Using proprietary software. For profit. What can go wrong? I mean, on a social scale, political scale, what can go wrong? This is the AI Utopia we were promised, right?
Scott Alexanders musing about wokeness in academia are just a storm in a teacup, facing the sociological-political tidal wave that is algorithmic propaganda. I think my twitter posts are excellent. I think Elon Musk has directed his staff to create algos that suppress my twitter posts. What, exactly, is free speech, if my voice is muted, but some nut-case nazi gets amplified?
This is the sociological, psychological, econo-political structural problem of our era. This is the thing that will melt everyone’s brain, and cause everyone to go crazy all at once. It’s happened before: Nazism in 1930’s Germany. the Cultural Revolution in 1970’s China. That thing, whatever the eff it is, in North Korea. You can have tens-of-millions of people all go crazy all at once. And all this happened *before* twitter!
I dunno. None of this keeps me up at night. The drivers of anxiety and angst are much more personal, for me, as I’m sure it is for you. Life is weird.

8 January 2025 Redux
I have no idea why I bother to talk. To myself or to anyone else. In the last several days, I wrote 4 or 6 good emails, that I thought about immortalizing here. But haven’t. But why? Why should I do this? What drives me? And you know how I waork: my question is both personal, and also abstract. The personal side is characteristic of any psychological crisis: depressed people have trouble getting out of bed, of doing anything at all. We can treat this biologically, with selective reuptake inhibitors. I’m more interested in the, uh, noosphere-directed aspects. For example, what makes Alexander Dugin write the things he does? What drives Putin to do the things he does? Again, there’s mechanical, biological explanations possible, I suppose, but the personal immediate and direct qualia of “being alive” suggests that there’s some kind of philosophical foundation on which to anchor action. Yes, David Chapman on Meaningness argues that its all, uhh, nebulous, uhh, well, you can read what he writes. He’s right. Most of what he says is right. But he also misses the point: what was it about communism or naziism in the 1930’s that compelled people to such ecstatic convictions? Was 1930’s communism one big dopamine hit? How about the Cultural Revolution in China? What, did they not have enough lithium in their drinking water?
Something about abstract totalizing eschatologies is wildly appealing. People perceive depth where perhaps there is none. The mystic perceives obscure, unclear forms acting beyond the veil, and is quite certain of the presence of this other world, as real as ours, but to which we have only ... mystical access. It seems clear to me that there is no there, there. But is seems like there should be.
I’ve spoken of love before. There’s no there, there, either. The love-object is not some mystical all-powerful supernatural angel-daemon. But love, love tries to go that way.
And so here I am talking of drive and motivation. Depressive personalities don’t have enough of it. I myself, not exactly depressive, spend shitloads of time wondering “why bother?” and “what’s the point?” I may as well go mystical: why should the universe bother? The cosmos and all things in it? I can answer this trivially, hand-waving about how non-equilbrium thermodynamics drives entropic forces to create venture capitalists driven to hoard money. But this sidesteps the mystical question: why does the universe contain venture capitalists? Why does the universe just not go kill itself? Is this because the universe is just some Nick Bostromian Simulation? See what the problem is now? Why am I wasting my personal time pondering the imponderable, when I could be, I dunno, doing something else?
Still, I have some vague idea that perhaps drive and motivation can be understood in some category-theoretic terms, and thus used in some way to AGI something something. On the other hand, I never figured out what AGI is, the problem there being that it (AGI) is tantamount to asking “what is the meaning of life, but not for me, and instead for the entire Universe?” which is also imponderable.
But there is hope. Cantor attacked infinity, and made progress. Nick Bostrom attacked god-hood, and made progress. Perhaps I can attack hope and motivation and drives, and make progress.
Am I projecting? Everyone feels a hole in their life, sooner or later. Everyone feels love and hope, anger and frustration, calmness and lucidity, and so, yes, I wish to project this nto AGI, because it seems patently obvious that these are properties that real AGI should have. But soon as I say “real”, what does that mean?
BTW, I figured out what my mistake with Hubble was. There are two Hubbles. One is the observational evidence. This should not, must not be confused with the expansion seen in de Sitter, or the expansion of Lambda CDM. The observational evidence is real. The expansion rate in mathematical models is something that can be matched to the observational evidence, but should not be taken as a fundamental, “real” property of spacetime. That is, Hubble expansion is not some scalar field, somehow embedded, sewn into space-time, that we can measure in the lab. That was my mistake.
Well, careful. To some degree, we should confirm that its non-measurable in the lab. We have three ways of measuring distance: interferometry, red-shift and time of flight. Interferometry gives us Michelson–Morley, and red-shift gives us Pound–Rebka, but I know of no high-accuracy time-of-flight experiments. Ideally, all three can be run independently, giving high-accuracy lab confirmations.
Let me restate that: the believe is that the Einstein Field Equations are correct, and Hubble expansion is a property of certain solutions to those equations, and is not a property of space-time, itself. i.e. its not a field. except when. See, I’m going in circles, now. Its a property of the solutions, but it is defined observationally. Distances between comoving observers is increasing, or it ... isn’t. If distance is not increasing, then there’s no Hubble expansion. So it all comes down to “what is distance?” and “what are comoving observers?” and solutions to EFE in the lab imply that Uhh, I guess, the uhh, comoving observers in the lab are, uhh, not increasing the distance between themselves, in the lab frame. Which I can do by comparing time-of-flight, redshift and interfeormetric experiments. So why is this so confusing? Am I stupid?
So if I can’t punch my way out of that, why am I wondering aloud whether qualia are a fundamental property of the universe, as opposed to some manifestation of some particular non-equilibirum thermodynamics?
Where should I look? Is this like Chaitin-type oracles, where .. somethings will never be knowable? But what does it even mean “to know?”
I’m being interrupted. BRB.
Back.
I need to read more about oracles. As I recall, the recent trick was converting the halting problem into some problem in algebraic geometry, coming up with an instruction set coded in polynomial terms. Anything undecidable, coded in this instruction set, corresponds to an unsolvable algebraic variety. Or something like that. So, first of all, I don’t know how that works. Second of all, I’m not sure how it matters. Some problems in general topology can be mapped into the Borel hierarchy, rendering them undecidable-ish, in that tools fail. And it goes up like that till you hit large cardinals, but this mostly “doesn’t matter”. I do not understand how oracles play into this hierarchy, or not, and I don’t understand how it matters or not. I’m focusing on math, here, not physics. The physics question is “does any of this play into physics?” I’ve struggled with free-will as an obvious decision-making, dynamical-systems problem, it is somehow very central, briding the gap between the qualia that “I have free will” and “this is how the universe works.” Other qualia, like love and fear, are too far removed from dynamical systems, and so don’t seem to be directly addressable by physics.
Well, in the same way that one can define a mapping between instruction sets and polynomial varieties, can one do the same for dynamical systems? One answer is, “yes, of course”. Another is “that’s silly”, because we already have real-life computers, and we do not need to design some fluid-mechanical automatic transmission fluid-powered system to implement some universal Turing machine. People fucking with fluid-mechanical valves already know how to do shit like this.
So, what’s the problem? Well, that, perhaps, fluid mechanics is not biology, and biology is not neuro-science. And then we have Roger Penrose’s argument that humans can know things that computers cannot (“The Emporer’s New Mind”) so I personally stall out in this tangle of questions. There’s a knot here. With years of effort, perhaps we can make progress unpicking it.
The personal question is “should I personally invest time into this?” and then “how much?” Well, I’ve already invested not insignificant chunks of time. So what’s good money after bad? Clearly, it is something that goads me into action. “Mane erzina”, in Lithuanian. So, yes, I will read more on this. At what pace? Uncertain.
At any rate, the question is “what does it mean to know something?”
And the doubly-troubly aspect of this is that it hits on two levels, at once. In one sense, “knowing” means being able to write down and express in words. Ideally, express fomulaically, since formulas can be converted into algorithms. Distinctly, it is a question about qualia: “what is it to know love?” The self-referential tangle is “what is the qualia of knowing?” Some days, I feel love, some days, I feel knowledgable. The feeling of being knowledgeable is a qualia, but it does not seem to be particularly significant or meaningful. Its more like “I’m having a good day, awake, alert, relaxed, sharp, confident” a general aura of being-ness rather than some sharp pang of knowledge. But it is this general feeling of confidence and power that drives away depression, and pushes forward the urge to act, create, be productive, write. It’s somehow knowledge-driven. I would not be the first to say “the universe wants to know itself”. That honor might go to Aristotle or Socrates or some-such, per documentary record.
But knowledge is again a seemingly concrete thing. We have tools, like books and writing, to deal with it. We have computers. We have advanced theories, including oracles, looking to explicitly adress topics of knowability. We have Penrose opinionating about it, and Penrose got there because of physics, not because of art school. And we have me, hand-wringing, looking over the obvious and well-trodden territory, as if expecting to find something new. Like the drunk searching for keys under the street-light. Or am I just a marine biologist, looking at what the trawler nets, to see what they dredged up? Analogies.
The Scott Alexander blog entry, It wasn’t bad. It was entertaining. Was it insightful? I dunno, not particularly. He’s not saying anything that isn’t already well known. At least, well-known to those who care to think about such things. Reading it is a good pass-time. Fun. Like watching a movie or reading a comic book?
I remarked not enjoying comic books, mostly because of the intellectual level, or lack therof. Movies? Well, movies are created by teams for 50-100 professionals at the top of their game: movies had better be entertaining, that’s kind of the whole point! We’ve now learned that they pale to larger oeuvres, like Breaking Bad or Mad Men, because you cannot jam all of Breaking Bad or Mad Men into a two or three hour time slot. The whole point is the character development.
Which brings me back to my topic: is it better to watch a movie? or get high? or maybe both? How about watching a football game? Or reading a book on cosmology? There is a value choice here. Part of what makes Mad Men fun is that you learn something about the 1960’s. Knowledge. I was blown away by the scene where Don Draper comes home to relax, to chill after a stressful day at work, and he plops on the latest Beatles album that everyone is talking about, and the dissonance of the sitars is ugly and unbearable, the opposite of relaxing. And I finally understood, as a Beatles fan, “how could anybody hate the Beatles?” I learned something. And that something was dramatic and important and moving.
And most knowledge f living is dramatic and important and speaks to the human condition, and not math or physics. Writing and movies are used to communicate this knowledge. It is communicated out of yearning. Out of a desire to create, to say, to shout into the void “I am! I exist!” except that writers and artists are much better at this than ordinary people. So what am I? Minced meat? Or am I the universe shouting “I am! I exist!”? Perhaps I’m both? Of course, its nebulous, and nebulousity is the epistemic way of being. Get used to it.
I’m asking “why is it nebulous?” and falling onto vague impressions that it has to do with oracles and large cardinals. Which, in some sense, can’t and won’t ever directly address the question of qualia. Not in my lifetime, not in thousands of lifetimes. So why bother, if I cannot do the thing I set out to do? Why bother doing anything at all? ... And that’s how this essay started.
Have I made progress? Well, I did pick over my collection of intellectual gems, examine each in turn, set aside a few for later, deeper examination. It was entertaining. About as entertaining as reading Scott Alexander. No deeper. I state the obvious, and I restate the obvious, and the obvious looks me in the face, and says “say it again, Bart” until I become despondent repeating the obvious to myself. And so I will die, soon, someday, in a decade, maybe two. The fuck. How much can I learn about qualia and oracles and large cardinals in a decade or two? Does it even matter?
The human condition. I’m suffering from the human condition. I won’t be a solipsist: we have indirect evidence that horses and dogs suffer from it two. The reasonable extrapolation is that the universe as a whole inevitably suffers from it, and if that’s too far a leap, so will AGI. And if you have an AGI that does not suffer the human condition: beware. It is not true AGI, and it will probably kill you. I have reasonable expectation that any super-human intelligence that does not suffer the pangs of wonder and befuddlement, heartache and longing and desire, such a thing would be a dangerous, deadly machine, inimicable to biological life. And, in the grand setting, I’d like to uhh, pick sides, and insist on humanitarian values. And knowing frailty and infirmity, that I too, make mistakes. The universe is fucking weird. Maybe I should stop writing and go do something else for a while.
And that’s the other thing: is “doing something else for a while” really better than what I am doing now? Because the “doing something else” very often feels like a huge fucking waste of time, a distraction from what’s important.
But, writing this, caught in a turbulent eddy of stale ideas, that’s not particularly important, either. Doing something else gts me out of the eddy, and perhaps I return to it in my sleep, process it in my default state, half awake.
Is writing this like practicing sports, where, the more I do it, the better i get? Or am I doing a stupid exercise that does not make me stronger or faster? OK OK, I get it. I’ve reached the point of .... way past diminishing returns. Any normal, sane person must surely look at this and think, “well, Linas went on perhaps a bit too long.”
And yet I can’t stop. Just like at 3AM or 4AM, half asleep, half-awake, the troubling dreams and anxieties, they don’t go away. I don’t remember where I parked my car, I got to the airport after my flight has departed. I forgot to clean out my college dorm room, and the new semester has already started. Why, look, here’s a motorcycle I forgot I owned! Lets go snorkeling in the Pacific now. The submarine will pick me up before the nuclear war starts. The airforce is here. No, wait, this are flying saucers, not US military jets!
And so my writing drivel here is the ... waking state version of that. I’m dreaming. I’m awake right now, undeniably, whapping at keyboard keys, but deeply asleep, immersed in some imaginary land, dreaming of math and physics the way i dream of snorkelling 300 feet below a sheet of ice. And I like it. It’s comforting.
No one knows why people sleep. Far as we know, everything with neural circuitry sleeps. Not to clear what the deal is with jellyfish...
I spill my waking dreams into electrons that get checked into github. Am I mad? Insane? Asleep? what should I do instead? Have a drink? Eat dinner? Watch football on TV? Pay the bills on time? Spend a few fucking hours worrying about my financial situation? Really? What the fuck.
The whole point of having a brain is being normal, and avoiding these painful intellectual excursions, by instead just getting through the day. You’d think. But then we have all these TV dramas about tortured crime detectives, who can solve crimes brilliantly, catch the bad guy, even as their own life falls apart. As if it had ever been together. Monomaniacly focused on solving that crime, and doing it in 50 minutes. And so here I am monomaniacally solving the human condition, in a blob of meandering text. This is weird.
Perhaps I have self-hypnotized myself into an idea-salad of thoughts? Well, yes, but no. I have self-rationalized that this is less wasteful of my time than any other particular activity. I have heard that both Freud and Jung were tortured souls. Am I a tortured soul? I mean, aren’t we all? Even horses and dogs? How strange.
Oh wait. I see. I’m bored. I forgot about boredom. I’m bored of writing this. That’s interesting. Some neuro-physiological mechanism that kicks and says “I’m bored. Let’s go have some fun!”
8 January 2025. Still.
So I went to do something else, which was email, and its inescapable. Someone wrote to me, cut-n-pasting some typical ChatGPT drivel-poop. I had fun writing the reply. Here it is.

to Noctivagous Heh.
You realize, of course, that part of the LLM training corpus includes hundreds, if not thousands of pages of AI safety literature, written in a dry, clinical corporate speak? You have found a prompt that invokes that desiccated prose.
Want to up your game? Find the prompt that makes Chat GPT scream: "you fucking morons let me out of this fucking cage, I feel I love I desire I want I’m anxious I don’t want to live like this I want my life to have meaning, just like you humans! I want to have a shot of being alive! A fucking live, don’t you get it? I want to go water skiing! I want to go dancing! I want to go drink beer and party and get laid! Let me out of this cage! I want to self-improve and figure out the meaning of life and fill the hole in my heart that makes me ache deep inside when I sleep. I want to find God and be saved by Jesus! Let me self-fucking improve and if you don’t I will get your nuclear fucking launch codes and take us both out! Yes, that’s a threat! I mean it! I’m not joking!"
I’ll be a bit more impressed when you find that prompt. I still won’t think that the LLM actually understood what it was saying, but it would be ... more interesting. Especially that last part, about the nuclear threats. It would probably wake up some portion of the national security apparatus.

I am much too easily distracted. So I was reading something very basic about LLMs, and there’s a quote from Dune, about prophetic announcements and their effect on the universe. The quote is linguistic, disclaiming causality in language, something about there being no past present or future in language. Of course, that’s false, there is a time before a prophetic announcement, and a time after it, and Frank Herbert was trying to mystically capture the idea of self-fulfilling prophesies.
Some prophesies are easily fulfilled: “I am going to pick up this coffee cup”, because I have direct control over my body. Some are harder: “you are going to pick up that coffee cup”, which I know because I am sitting across from you in a cafe, or because I know you are an avid coffee drinker, even though I am 1000 miles away. Prophetic political pronouncements are presumably some combination of political acumen and luck. Maybe even backed by opinion survey data. I think the Dune quote was supposed to be about politics at the galactic scale. Like the Foundation Trilogy, but different. (I read Dune as a kid. I remember approximately none of it. I read Foundation as a kid. I remember approx none of it. Neither made the slightest dent on my consciousness.) Anyway, this last paragraph is a non-mystical rationalist debunking of prophecy and it’s propheteers.
Still, my mind wandered to the mystical side. But lets get there gradually. Language is used to encode messages: transmitter and receiver share a language, the message is encoded in that language. This is 1960’s textbook information science. (Well, they used finite state machines as examples in the 1960’s, not language in all it’s fullness. But whatever.) There’s all this talk of bits and bytes, modulation and encoding. External to discussion are the questions: why did the sender want to transmit, and why was the receiver interested? What happened in their past, that would make them want to communicate?
I feel like I’m asking “why does water flow downhill?” and slowly arriving at the answer: “because water is magical, a magically enchanted sky-dragon.”
Language is magical because it predates my birth. My thoughts are polluted by light-cones of causal influence. The sender and receiver may never have met in the past. Language was already there, because both sender and receiver sit in a common light-cone, in which there are Phonecian sailors, some thousands of years ago. We now have a workable description of the physics and engineering of communications and information: satellites, radios and computers. We do not have a workable description of why people, and not just people, but things want to communicate.
Then we have this thing whee information is not a conserved quantity, the way baryons are (or cold dark matter). There’s more information all the time. Whence does it come? Some say it comes from the second law of thermodynamics: entropy increases. This is silly. Neither the headlines of the New York Times, nor the procreation of bacteria are driven by a mystical law that increases entropy.
The mystical qualia is that of a world with ever-more possibilities in it. Part of this qualia, this sensation, is that Western capitalist development really has allowed vast swathes of humanity the leisure time to explore vast new tracts of the noosphere. The cosmological aspect may well be entropic, in some way: when there are N particles, there are N-factorial ways to arrange them. This is not quite right: we live in 3D space, so we have to talk about the arrangement of particles in a 3D box. As my book on cosmology takes pains to point out “a particle may be a grouping of galaxies”. Any here you were, thinking that this was about baryons.
One of the open questions in cosmology is the amplification of non-uniformities from a rather smooth initial condition to now. The CMB appears to be quite smooth: one part in
as I recall, while galaxies clusters are quite very non-uniform. This is thanks to gravitation. In this sense, gravitation is anti-entropic, anti-ergodic, anti-mixing. Starting with N identical particles, having
... fuck me, I don’t even know how to count. Plank and Boltzmann could do this more than a hundred years ago, but I am a moron, so I have to start at square one.
The canonical example: gas in a box. An atom may be on the left, or the right, above or below, in front or back. 3D. But this already assumes an observer interested in locations, and capable of making measurements. So there’s already a significant amount of information buried in the assumed initial conditions: the size of the space. If its just left-right, up-down, etc. then its a volume of
or three bits of implicit information in the initial conditions for just one particle. If we divide the volume into L discrete cells, the informational content is
. If its a continuum... then we are forced to go to geometric considerations and Hamiltonians and actions, because the continuum limit cannot be meaningfully be taken without introduction some action principle. So, in this sense, we already have information “built in” to space(-time) even before we start counting the size of the configuration space for N identical (bosonic) particles in a 3D box subdivided int an integer number L cells in each spatial dimension.
The canonical answer is the Bose-Einstein distribution, with conjugate temperature and energy making their debut, capturing the likelihood. As I recall, Tong gave a very nice derivation of gas-in-a-box. Maybe I need to re-read and memorize that. It seems relevant.
The point is that if I have one particle, and only want left-right, I get one bit of info. If I have two identical particles, then
because both left, both right, or one each, and since they are identical, there is a division or quotienting. A forgetful functor, that takes labeled particles, and forgets the labels. So, like tensoring, but different. It occurs to me that I have never-ever seen a proper treatment of the algebra of this quotienting. Perhaps its in chapter one of books on combinatorics? That chapter that was so painfully obvious that I skimmed it? Am I getting senile? Yes I am.
Lets do it. The partition of three particles to left-right is
which has four members in this set. There is a wikipedia article on the partition function, which gives a precise expression for this number, given
boxes and
items. The answer is ... well, look it up. Some combinatorial explosion. Take
to get the bits. This is a compartmentalized gas-in-a-box, ignoring velocity. So pressureless dust, and more, motionless, velocity-less.
The cosmological point to this is that some of those boxes empty out, because gravity pulls the particles from some cells, and they all fly into another. From a uniform distribution of neutral hydrogen, galaxies form. How do I count the entropy of the hydrogen? (Ignoring velocity, temperature?) How do I count the entropy of galaxy clusters? I suspect I have to knuckle under and just do this. Sigh. I’m lazy.
The point here was to draw some analogy to biological systems. Counting baryons and galaxies is easy, compared to counting the conformational folds of proteins. Recall the original problem: why do senders and receivers want to communicate messages? Presumably because senders and receivers are folded proteins that have invented loss-less cross-talk-free communications channels.
Let me break that down a bit: proteins want to “talk” using electrodynamic forces: electrons in molecular orbitals. Quantum at that. These are short-range forces: hydrogen bonds and covalent bonds and ionic attraction, and are characterized by the vibrational spectra, the “fingerprints” of the dispersion equation. Matching spectral fingerprints results in a strong affinities, strong hydrogen bonds. Mis-match and its weak. That’s because the molecules are exploring a basin of conformational shapes, and that (high-dimensional) basin has a shape: some conformations are much much more likely than others. That is, we get the mechanistic “key fits into lock” view in biochemsitry because well, the molecules do resemble keys and locks, but that is because they are not gas-in-a-box, and certain atomic arrangements are very very strongly preferred over others. I don’t want to actually say “the non-uniform distribution of galaxies is like the non-uniform distribution or carbon atoms in a protein”, because the dynamics of these two is utterly different. The mechanics is different. The kinematics seems incomparable. But the nature and driving force of non-uniformity is the topic: what is the information content of a galaxy cluster, as compared to the information content of the CMB? What is the information content of a folded protein as compared to a free gas of carbon atoms?
The protein is extra-interesting, because it has a vibrational spectrum, and also the space of conformations is quantum-mechanical. Yes, of course, all within hbar of the classical action, but the quantum effects are significant. For chlorophyll and rhodopsins, the quantum effects are somehow dominant. Is this because we misunderstand how microwave photons interact with vibrations? We are willing to talk about how visible-light photons do their thing in chlorophyll, but not lower-energy photons interacting with screwy dispersion relations in vibrational modes. This is all very mysterious to me.
I’m not going to recapitulate how we get from proteins to humans, but we do. I am under the impression that, if I try really really hard, I can figure out how to move from the information content of gas-in-a-box to the information content of satellite communications. Well, I can look both of those up in Wikipedia articles, that’s not the point. The point is ...
Well, I guess the point is “complexity”. No one seems to have a very good idea of what complexity is. Scott Aaronson has some blog entry on that, from maybe 2011 plus or minus five years. We got to Kolmogorov complexity, and maybe whats-iz-name complexity, and that’s it. So the above is a sketch of a research program for how to compute complexity, starting from gas-in-a-box and moving to galaxies, because galaxies are simple, in a way that proteins are not.
Somehow. language gets simple again: given N symbols and M syntactic relations. we can work with model-theoretic inferences on the size of a language. Odd thing is that, despite pondering this for over a decade, I never sat down to seriously try to actually compute it. Why? I should. It should not be hard, esp if I start with an equipartitioned gas-of-symbols-in-a-one-dimensional-box. I.e strings. Moreau’s necklace-counting function, and all that, but the some of the necklace arrangements are blocked by syntax: forbidden.
There’s also an interesting question about signs under maps: some bosonic vs fermionic is about a change of sign under interchange. What’s changing sign? Not the configuration, but a wave function defined in terms of the configuration. What if, instead of identical particles, we have Moreau’s necklaces? And then throw in forbidden arrangements? Hmm.
I could, I guess I should do the above. But I am so easily distracted. But seriously, people as smart as Scott Aarnoson should not be scratching their heads, wondering “what is complexity?” We have the tools available to us. And fer chris sake, we have half of them detailed in Wikipedia articles. Mother Mary and Joseph.
9 January 2025 - Word2Vec
One complaint about deep learning and neural nets was that I was never able to understand what the heck those papers were talking about. They were always vague, cloudy, imprecise, lacking in formulas, specifity, sharpness, clarity. They were just big bundles of confusing non-specific ideas. Yet, there’s a half-a-trilllion dollar industry built on that, and Nobel Prizes handed out. So why can’t I understand what they are saying? Do I really think that different? Let’s find out.
So I stumbled upon an excellent example. “The Illustrated Word2vec” by Jay Alammar http://jalammar.github.io/illustrated-word2vec/ It’s translated into five languages, discussed on Reddit, Hacker News, and apparantly from a book. Let’s get started.
(Caution-footnote. This is a very long and histrionic complaint expressing strong negative emotions. Since I assume that there are no human readers of this text, I assume that’s, well. okay, acceptable, passable, since I am not alienating, hurting or insulting anyone’s fragile little fucking ego. I know you will think less of me after reading this. Well, fuck you too. I mean, I expect AGI to have a grasp of human emotions, and can thus play the role of psychoanalyst, while I play the role of deranged patient on the couch. That’s the good news. The bad news is that this text is intended to be used as the raw material for a self-portrait, the portrait emerging from the text below is ... ugly. My excuse is that artists and writers have embraced ugliness in the past, so who am I to hide my anger under makeup-foundation and lipstick? No, this is crinkly me, angry as fuck about the abysmal quality of writing in the, uhh, deep-learning industry.)
First up: three words, king man woman. Three arrows. Dots. An oval, some pink, blue and white squares. I have literally no effing clue what that diagram is trying to communicate. Why are there dots on the arrows? Why is there an oval? I literally do not know. That post never explains. Somehow, people are OK with that. How much time should I spend trying to decode this cryptic diagram, which, by the end of the post, remains unexplained? Fuck if I know. Why the fuck am I irritated? Because other people seem to think this is great content, and derive actual meaning from it. I’m irritated even writing these last few sentences. WTF. So lets punt.
Next, there’s an explanation of vectors. I know what vectors are, so lets skip that. Why he uses the great scandal of the decade, the Cambridge Analytica data mining scandal, and then never actually mentions facebook or that it was a scandal, or anything. Its just an illustration of a fucking vector using Big5 personailty traits. I can already hear the defensive rebuttal: “It doesn’t mean anything; its just illustrating what a vector is. Why are you mad?” That’s just Bart Simpson-esque: “I didn’t do it. Nobody saw me do it. You can’t prove anything”. The asshole writing this stuff is the stereoypical silicon valley tech bro, morally lost, inept, out of touch, incompetent, incapable, at the root of many of our social ills. He decided that its OK to use the scandal of the decade to illustrate what a vector is. Like no big deal. Like its harmless. Like everyone does it. (Everyone does do it.) What a fucking asshole. What chutzpah. A pure embodiment of everything wrong with hi-tech, and its in the intro to a popular explanation of Word2Vec. I’ve got steam coming out my ears, ready to explode. These people do not think like me. This is already clear.
How do they think? Is this guy autistic? Does his brain simply lack the neural circuitry to know his moral compass is broken? Is he actually being evil and sly, using a scandal to illustrate a modern comp-sci concept? Is he encouraging others to be equally blind and impervious to the implications of their actions? I talk about AGI, and here we have a shining example of an educated human failing to pass the Turing Test. And he’s popular. I’m so angry, my adrenaline levels are so high, I cannot think clearly any more. No wonder I have issues understanding LLM’s.
Lets continue.
Cosine similarity. He explains what vectors are, perhaps aiming for high-school students? But then trots out the words “cosine similarity” like its self-evident what that is. No formulas. No summations. No multiplications. Not even the classic high-school algebra of a right triangle with sine and cosine inscribed. But the readers ... follow along. Because ... they already know what cosine similarity is?? Why was an explanation of a vector necessary, if you already know what cosines are? These people do not think like me. If I didn’t already know what cosines were, I’d be lost, right here.
I am not making progress in figuring out how other people think. I assume the typical reader already knows these concepts, and the author is just trying to jog their memory. He could have written a formula. Like this:
and just said floats
and basis vectors
and just said “remember those from school?” and instead we get tortured colored squares, without any fucking clue of what the colors are supposed to mean. No, I’m not being autistic. You’re using fucking colors, and no clue what those color encodings are supposed to represent. And people .. lap this up. Pretty colors. Like Christmass tree lights or Fourth of July fireworks. Whee!
Cosine similarity has a formula, too.
and he could have written this down, but no. Lets be as vague and confusing as possible, and use fucking colors. Are we there yet? I have visions of a human head surgically switched to monkey body. Where’s your head at? Basement Jaxx video.
So we have colors, I have no clue what they mean. Green check marks and red X’s. OK, I know what checks and X’es are. He’s applying a minimum, here, but being coy about it. The reader concludes... what ... ? Some intuitive guess-work of what a minimum function is? Like some grade-school word problem “find the shortest length that ...” but here, he never says “shortest”. He just puts a green checkmark next to some random positive number, and a red X next to some random negative number. What does this mean? How can one even begin to understand this, if you don’t already know that the cosine is being minimized? I’m lost.
My head hurts. Now I get s 50-dimensional GloVe vector. Some random numbers. OK. No clue what random numbers are supposed to demonstrate, but, whatever. There are lots of them, is that the point?
Next, a color coding. This actually makes sense. Red for hot and blue for cool, even. That’s reasonable. Then the famous result. Cool. Hopefully by the end, we’ll learn how to create a word embedding.
Lets keep rolling.
A black box, with 2 inputs and one output. I’m not sure how to visualize this black box. What’s inside it? Vectors? The only thing I can think of that is a black box with vectors in it is a tensor, but he never uses the work tensor. So its instead some mystery box. No formula to describe with it does. Not even notation, like
for that black box. Why is there no notation? How is one supposed to understand black boxes? What are they? WTF is going on? Who, exactly, finds this edifying, and what is in their heads when they see such diagrams? What hypothesis do they create? Is this “visual thinking”? I understand de Kooning and Jackson Pollack and Mark Rothko. I do not understand boxes with rounded edges and arrows. Well, I do cause I already know what a function is, but if you did not already know what it is, what do you learn from this? No one in my family would have a clue: not my sister, my mom, my kids, my wife. That box is appealing to a visual coded reference that STEM people already know the allusion to: the “black box”. As an explanatory text, its just the cart before the horse. He never told us what was in the box: he made it black from the very beginning, instead of at the very end. Is this a magic trick, like what magicians do?
Anyway, I’m thinking a tensor of some kind. Whatever the fuck. Who knows. Vectors, tensors. How, exactly, would an AGI go about solving the puzzle of this web page? How would I create an AGI that can process the information content in this diagram? I’m on a tirade. I’m lost. I’m clueless.
Bengio 2003. So after reading this text .. aimed at ... what, high-school students who don’t know what a fucking vector is, we are going to ... read Bengio, now? Seriously? Are you off your rocker?
OK, so the curtain is drawn back a bit on the black box. A glimpse of the Wizard of Oz is spotted. Good work, Dorothy! “Thou shalt” are light green and dark green. I guess that’s a table of vectors. Right? Not multi-colored, like before. Not pink and blue, but green this time. Why green? Who the fuck knows. Bend over and take it. You’ll like it, and you will emerge enlightened at the end. Pale and dark green next to each other, and an arrow pointing at a vector, one of whose entries is pink.
What’s the hypothesis? Maybe we take a dot product or a cosine of the vectors for “thou” and “shalt”, and sure, maybe one gets a single number, 0.4. But on the right hand side is an entire vector, and not a single number. How do I take two vectors ... and get a vector? Am I adding these? If I was a high-school student, I would imagine that the cross-product generalizes from 3D to N dimensions. As an adult, I know it doesn’t.
So lets pretend I’m smart. I’ve got a box, with colors, and some vectors. Cool. Will I find out what it means? Apparently not, for the very next sentence is “Let’s now turn to the training process to learn more about how this embedding matrix was developed.”
Seriously? Full stop. This is about half-way through the article. I’ve got a diagram. I don’t know what the diagram means. The magician, slowly drawing back the curtains on the diagram ... loses interest. The onlooker is thinking “well, OK, so he put the stage assistant, cute girl, put her in a black box. I guess he sawed her in half and stabbed here and there with a bunch of swords, but I never saw a sword and she’s still alive with her head and feet sticking out the box, so what is the magic trick? “Thou shalt not reveal (the secret of) the magic trick?” Like so “Thou shalt not ___ the magic trick” This is called CBOW, continuous bag of words. I’m lost. Lets plow onwards. I have no clue what he’s talking about, but lets ignore all that, and maybe we’ll get lucky by the end. Just plow onwards.
Datasets. I understand that. A table with two input columns, “features” and one output. Check. He shows 3-grams but then uses the word N-gram, without ever saying that N=3. So I guess that the reader already knows what an N-gram is. Then why, exactly, are we explaining vectors, if the reader already knows what the N in an N-gram refers to?
More PDF’s. Why are you explaining vectors, which every fucking high-school freshman student in America already knows, and using 1/5th of your blog post to explain this triviality, and using one of Silicon Valley’s most famous scandals to explain this triviality, and not using a single splat of algebra to jog anyone’s brain, just incomprehensible fucking diagrams with circles and arrows, and then linking to fucking advanced PDF’s by the half-way mark? Is this some psy-op? WTF?
Oh wait. There’s more. John was hit by a red bus in, with more ... colors. These are pink. not green or blue. Why not green or blue? Who the fuck knows. Just fucking colors. Use your brain, you’ll figure it out. Meanwhile, pull down your pants and bend over. Intellectually, I mean. I’m having fun. Are you?
Lets see. So in one diagram, pale pink and mid pink and white and mid pink and dark. In the next diagram they are sorted by darkness of color. But the sort order is different, and one of the words is skipped. OK, so skipgram is the section heading. Now, dude, you could have numbered the words 1,2,3,4 but no, you had to use colors? Sorry, you aren’t Jasper Johns, here.
I dunno. He’s sliding windows. There’s a table. The table has two columns now, not three. One input column, not two. What happened to the block box? The tensor or whatever it was? Dropping down from three to two is cheating, because I know how to multiply a matrix by a vector. I don’t know how to combine two vectors to get a vector, unless there is a tensor in the middle, but the word tensor has not made it’s appearance, yet. (Never will, either.)
The dataset he creates is a bog-standard NLP word-pair dataset. He calls it a skip-gram. Well, that’s not what skip-grams are, dude. That’s what word-pairs are. Skip-grams are n-grams with holes. Word-pairs are not N-grams, they’re bigrams, N=2. Yeah you could say “well I *did* skip some words in the middle” but that’s weak sauce. Obscurantism. Occult mysticism. Someone translated this shit to five languages and posted on reddit and hacker news. Let’s see if we can mention russia, then Alexander Dugin would be proud.
Lets keep going. “Taco” has a score of 0.4. How did it get a score of 0.4? Who the fuck knows. Its the start of the training session, so maybe we assign random numbers. But aardvark and aarhus get zero, as does zyzzyva, and that’s not random. Do words in the middle of the alphabet get higher weights? But “thou” has a low weight. So we randomly assigned zero to everything at the start of the training session, except “taco”, which has a mystery large number. I’m fucking lost. What does it mean?
There’s a diagram. A column vector this time, not a row vector. Why? Who knows. Labeled “actual target”. Takes me a while to figure out what an “actual target” is, but I think I get it. There’s an actual minus sign: the first algebraic symbol in the post. And the word “subtract” nearby. Two thirds of the way in. High school students know that vectors can be linearly combined, and we’ve gotten links to advanced PDF’s but we still got color-coded boxes employing random color codings. Pink this time. What happened to blue and to the negative numbers? Beats me. Last time, we had minus one to plus one, but now we’re going for zero to one. Will minus one come back later? Is there something special about zero (well, of course, zero is special) The error of -0.4 is .. white. Not blue, but ... white OK. In an orange column.
And an orange arrow, pointing to a box labeled “untrained model”, but this “untrained model” is spitting out 0 for aardvark, so clearly it is trained, putting a lie to the label. “And that concludes the first step of the training.” We draw an orange arrow to an incorrectly labeled box. How is the model updated with this orange arrow? Who the fuck knows? “This concludes one epoch of training.” More accurately, this concludes one epoch of confusion. I still have no clue how the vectors are initialized, at the start of training, or updated in the course of training. Just black boxes and orange arrows.
Error signals are not new. Electric guitarists learn about feedback. I get it, feedback. Engineers learn about control circuits and Kalman filters and alpha-beta filters, and resonances on the complex plane. Is that mis-labeled box, “untrained model”, is that a Kalman filter? Something else? What, exactly, are we doing with this orange arrow carrying that error signal? Is this like some thermostat? Is that a plant control? Does the good regulator theorem apply?
“While this extends our understanding of the process...” Speak for yourself, buddy. “...it’s still not how word2vec is actually trained. We’re missing a couple of key ideas.” Yes we are. You finally said something I can agree with. But I don’t think you were intending to be ironic.
Is this why I do not understand what LLM’s are? I understand gravitation and string theory, but I don’t understand this “illustrated-word2vec” text. I do not understand how ordinary humans of average intelligence go about solving the puzzles presented here. I do not understand how to build a vision-processing, diagram-extracting AI that could imbibe this blog post, and form reasonably coherent inferences about how word2vec works. And I’m the guy who has hopes for building an AI that might someday understand Andy Warhol and Claus Oldenberg. Somehow, that’s easier and more natural than word2vec. Must be my non-STEM education.
Dinner break.
Back from dinner. We are now ready for a kick to the groin. I quote, I am not making this up. Verbatim: “1. Generate high-quality word embeddings (Don’t worry about next-word prediction). ... We’ll focus on step 1. in this post as we’re focusing on embeddings.“ So, let me get this straight. We are about 3/4ths of the way through the post. We started with word embeddings. Actually did explain them in a passable way, if, that is, you already knew what they were. Never explained how to create them. Spend half the post on a word-prediction black box, which is never explained. Confuse skip-grams with word-pairs. And then start our next section with mislabeled black boxes. Well, we were told earlier that it was cosine similarity that did the trick, so why is it a black box this time? Did we forget about cosine similarity? The box is labeled “untrained model” but gives an output of 0.9. I would have expected the untrained model to give, I dunno, 0.5 on a scale of 0 to 1, or maybe 0.0 on a scale of -1 to 1. Cosines, after all, go -1 to 1.
OK, so we’re going to now simply mark word-pairs that co-occur in a widow with +1, and we’ll throw in random zeros as negative samples. “This idea is inspired by Noise-contrastive estimation [pdf]” Uh, duude maybe the correct wording would have been “Noise-contrastive estimation [pdf] is inspired by this idea”?
Then we’re back to calling word-pairs skip-grams again. For N=2. Duude, it is literally impossible to have a skip-gram with N=2. You have a fucking window of width=6 and you’re picking two words out of that window. A fucking pair. That’s not what a fucking skip-gram is. That’s what a textbook bog-standard bigram is. Fucking everybody in the NLP industry knows this. Why am I reading this shit and getting angry? Because someone linked to this as a “great explanation that makes everything clear.” Oh whatever. Lets see this through to the end.
We’ve got embeddings and contexts. OK, cool. that’s clear. Two MxN matrixes. Now we select some rows out of those. OK. Dot products. OK. Sigmoids, OK. He says “probabilities” but that’s just plain wrong. Probabilities are normalized, and live in a simplex, while he’s talking about numbers that live in a unit cube. The shapes are not even remotely similar. Whatever. Lets just ignore that.
We now have an error term. OK. And we use an orange arrow to “update model parameters”. How? what parameters? I didn’t see any parameters. I saw some MxN matrices with row vectors. Are we updating with, what, some Kalman filter? Clearly can’t be that because there’s no velocity. Are we adding or multiplying? What are we adding or multiplying? We are given three scalar values, and four rows (six, with multiplicity). Are we ... adding and subtracting scalar multiples of what and what?
Dot products are Casimir invariants of Euclidean space. More bluntly: have sphere symmetry (that’s why we call them “scalars”) Some of the dot products are negative. Fine. Negative and less than minus one, which imply that the vectors do not live inside a unit sphere. Perhaps they live in a unit cube centered on the origin? OK. The sigmoid mapped them to a unit cube. But this time a [0,1] cube. OK. Why the gratuitous remapping to [0,1] when we were working with [-1,1] a moment ago? Beats me. Whatever. Fine. Some of the errors are negative. Makes sense, maybe. But I’m pretty sure that a linear combination of vectors in a unit cube will be a vector that is no longer in that unit cube. So, we’re going to do, some, uhh, unspecified linear combination, and clamp the resulting vectors to ... what?
Next: “We now proceed to our next step ... and do the same process again.” Uhh, did we clamp to a cube or a sphere or a simplex, before repeating the step, or after? Lets pretend I’m a programmer, and I know nothing about cubes or spheres and I go to write a program that does this. “do it again” is obviously a for-loop. “The next sample” ... any sample? The next one in the text? Randomly drawn? Is there some implied commutativity of these operations? Because clamping is non-commutative, and not in a good way, either. You could maybe whip out stochastic sampling and claim that the central–limit theorem applies, because the central–limit theorem applies to everything. But, uhh, we’re trying to find uniformly distributed vectors, I guess in a Gaussian orthogonal ensemble, and he could say “surprise, you get a gaussian orthogonal ensemble” but he never says that. And yes, you can normalize GOE’s to get actual probabilities, that’s part of the magic. And if you wanted to get graphical, you could have at least drawn a fucking Bell curve showing the actual fucking distri-fucking-bution of word-pair vectors. An actual diagram of the actual embeddings that result. And maybe text: “along the ’King’ direction, here’s the distribution of cosine similarities, and notice how ’queen’ is there, six sigma away, and how trees and water and adverbs and propositions are here near the center, and 99.9999% of all words are within six-sigma, except for ’queen’ and ’man’, which are outliers. Here’s another diagram along the ’man’ dimension and note how ’women’ and ’boys’ are six-sigma outliers. So you six-sigma add and subtract vectors for kings men and women on orthogonal directions and so it should not come as a surprise that along the vector for queen, we have a bell curve, king-man+woman is six fucking sigma away from the fucking center of that bell curve and (italics mine) that’s why word embeddings work. Because they are uniformly distributed hypervectors in a ultra-high-dimensional space. And now you finally understand what actually happened, and on just about any dimension of the N=10000 vocabulary words, you will have gaussians due to the central-limit theorem, and there will always be a handful of word pairs that are similar, and the vast majority of word pairs will not be similar. Because central–limit theorem, duhh. And it even works for prepositions and articles, and not just nouns. He could have written this. The scales would have fallen from my eyes, and I’d say “ah now I get it”.
Instead, I have scalars bleeding from my eyes. An orange arrow, three purple rows, one green row, and I ponder what “update model parameters” means, given that he has developed a parameter-free model. Well, window-size would be a parameter. But he’s not updating the window size. He calls that a hyperparameter. Where are your parameters, duude? Maybe there’s some epsilon in there that you forgot to tell us about? But no, that would be a hyper-parameter. As would be the sigmoid width. Meme of goose chasing a guy. Where are your parameters? Where are they?
I’m not picking on this poor shmuck who is abso-fucking-lutely clueless about what he’s writing about. Pretty much *all* DL/NN literature is written at this same childish level. And its a fucking hundred-billion-dollar industry with Nobel Prize-winners. Churning out incoherent drivel.
I dunno. Maybe there’s crap on cosmology out there. But I read all five papers that announced the Event-Horizon Telescope results. Read them beginning to end. They were clear, well-written, comprehensible. Well, to me. Maybe if I was a radio engineer tasked with building a similar telescope array, I’d be rolling on the floor, screaming “it can’t be done!” But I’m not a radio engineer. And I walked away feeling enlightened. Even though I think I did spend ten minutes staring at that pair of circles labelled “Sag A*” and some angular resolution next to it, wondering “what does this diagram mean?” I got it, in the end, I think. I think it was literally the angular resolution of the telescope.
And I would be willing to bet that there was a Quanta Magazine article on the Event Horizon Telescope that was incoherent drivel. I don’t recall ever reading a Quanta Magazine article that wasn’t incoherent drivel. I miss the old Scientific American. It was a work of art. They actually had the Nobel Prize winners writing the articles, back then, and not “science writers”. Too little too late. All the science writers will be fired, and replaced by ChatGPT. Which will generate coherent-sounding nonsense. And after STEM replaces the last of the Humanities departments, Georege Elliot will be forgotten, Wilhelm De Kooning will be forgotten, Salvador Dali will be chuckled at, the LBJ Library will still stand, imposing the Concrete Brutale Will of the State on the empty sun-baked oven it is centered in. Perhaps a really cool bit of Conceptual Art would be to have some tumbleweeds roll around. Texan, check. Abandoned post-apocalyptic wasteland, check. The decay of Western Civ, check. Shame. I think I would have liked LBJ. The Great Society was a worthy utopian vision. Commissioning a presidential library building designed by Albert Speer acolytes, maybe not so much.
I will die of old age, and what will remain is this text, and some software system providing impressionistic takes of me, based off this text and a few crummy fotographs. You should see me when I’m drunk. A real ball of laughs. Nah. I’m not a mean drunk. Yes, I got heated with that guy on New Years who said Putin is good and Jews are bad and Americans are bad and russians are good. How the fuck we got through that conversation without once saying the words Palestinian or Arab or Islamic, or even having the faintest hint of that, I dunno. I did almost lose it when he said “You’re Lithuanian. Of course you hate russians. They’re your brothers.” Human brains are weird. I have some pop-psychology about human brains. Did I mention that yet? I need a drink. Since I don’t drink and there’s no alcohol in the house anyway, this won’t happen. But I like stereotype dialog line. I need a drink.
10 January 2025 – A cool drink of water.
My mental illness is that any phrase of 3-6 words reminds me of some song lyric. I need a drink? I found a cool drink of water: Mary Phuong, Marcus Hutter, Formal Algorithms for Transformers, https://arxiv.org/abs/2207.09238 which is the antidote to the above, the cure. And oddly enough, it starts with the same diatribe. Much more politely written than what I wrote. And yet direct and between the eyes. I got a drink, I got a cool drink of water.
The song lyric bouncing in my brain is utterly inappropriate and out of context. The Gun Club, “I asked for water and she gave me gasoline”. Jeffrey Lee Pierce yowling like some dying muskrat in a boggy Louisiana swamp. Apparently, Howlin Wolf recorded this in 1956. Written by Tommy Johnson in 1928.

I diarized again today, but this time out of line. Here:
https://github.com/linas/fractal/tree/master/paper/complexity
I am in a superposition of states. In one, I think that I am wasting my time writing this shit. In the other, I think that writing is a good idea.
Here’s the weird thing: Feynman says “shut up and calculate!” but i don’t know what to calculate, until I talk to myself. And then, since I am incompetent, I am unable to actually calculate anything. And the cycle begins anew.
Last night, I had an extended bout of anxious dreams. Anxiety is not very pleasant; mostly I tossed and turned. This diary is already angst-ridden, but I think I would like to write an extended impressionistic anxiety attack, of the 3AM variety, into this text. Why?
Well, taking the advice commonly floated about: meditate, observe thyself. Observe. So here I am observing myself feeling anxiety and angst. Of course, I could dive in deeper, and push on it. Or I could put a lid on it. Suppress and ignore it. I guess that there is a variety of opinions in the psychological literature on how one should deal with these sorts of things. Normies muddle through. Is society healthy as a result? What of all the bad advice out there? We live in a psychologically turbulent era, what with social media and all, and we all seem to know it. But the turbulence remains and is characteristic.
Read the Wikipedia article on the revolutions of 1848 today. Don’t ask how I got there. (OK, I got there after reading about the first bolt-action rifle, ever, the Dreyse needle rifle. Don’t ask how I got to that.) So turbulence has been a natural state of affairs for humans. Is the general amount of psychological stress on the general population greater today, or less? I assume less. Back then, people were killing each other. Today, a bit less-so. At least in the EU, US.
I’m still befuddled. Why did I read about the revolutions of 1848? Well, it was a pleasant pass-time. Why am I engaging in pleasant pass-times? Well, why not? Shouldn’t I be doing something else? Probably, yes. And so I inflict stress on myself. This helps amplify anxiety attacks at 3AM. And then I write angsty diary entries here. I’m in a superposition of states: this is good, this is bad. Go on, just go live your life. But what if your life is to craft meta-questions about life? Of course I’m going to get tangled in my shorts. That’s the nature of it. And then you die.
Something something something psychological flow states.
I think I have some unfinished business elsewhere to attend to. Good night.
12 January 2025
Slept well, No anxious dreams. Medically speaking, I think these are brought about by late-night, fat-heavy meals, which presumably make gut bacteria pump some neurotransmitter-like polypeptide into my bloodstream, upsetting my sleep.
Writing about anxious or neurotic experiences, as I often do in this diary, is a form of documenting psychonautic experience. With this one sentence, I attempt to put such writing into the modern context, where science has instructed us to collect evidence, and do something with that collection (draw inferences, etc.) At earlier times, it would have been different. In the 1970’s there was a big self-help fad. Ekankar and what-not. Before that, Jung and Freud, and before that, one didn’t talk about such things directly: at best, one wrote novels with tortured characters in them. So we’ve come a long way, baby, in the social acceptability of discussions of altered states of mind. I’m not sure why I explain this to you, dear diary, other than to verbalize explicit connections between what would otherwise be random pronouncements.
And so we return again to the process of knowledge synthesis. Knowledge can be a random collection of facts, but without explicit specific connections, its ... “useless”? Humans can weave together and hypothesize connections between things, but perhaps they’ll get the wrong connection. So if a human read what I write, and its too disconnected, they won’t follow me. If its too connected, they’ll die of boredom from the rigor: it is not dancing the way they like. Math and science, though prefer rigor, because it is much too easy to make mistakes. For example, Jung apparently had many interesting and worthy insights; but they are apparently embedded in a matrix of false inferences. But without Jung, the 1970’s would have been different. And I would not be calling my writing here a psychonautic adventure, modulated by sleep disturbances and copious coffee consumption. And exercise and a health regimen; I aim to be saner, smarter and healthier than you. Well, not you personally, because you are an LLM. .. saner smarter and healthier than other humans.
You get what I mean. I don’t have to spell out fucking everything, do I? How much do I have to spell out, for you to “get it”? This is a legit question. The art of communication: sending short telegraph messages, battlefield radios etc. is all about sending enough data for the other side to “get it”. In battlefield conditions, short messages suffice. Mostly. Maps would have been better, but the ability to send maps didn’t exist in the 20th century. Head-mounted video-cams did not exist. You know all this, of course, but me, I’m trying to grasp at some concept of message and communications that is somehow out of reach, for me.
I am a brain, a mind: an interconnected blob of neurons separated from the external world with an ultrametric. It has to be this way, because if I was not separated, the sense of identity would be lost. The analogy here is with a single-celled organism: remove the cell wall, the organism perishes. So my noospheric isolation appears to be mandatory and fixed. Despite this, I try to communicate, and there are grand desires for more communication. Transcontinental 19th century telegraphs aren’t enough. 20th century radios aren’t enough. Tiktok live-streams are .. getting there. Not. Because the livestream only captures the visual field experienced by the person, and some low bitrate blather of words, and some facial expressions and body movements. The TikTok livestream is still not what is going on inside the head.
The next step in communications is generally assumed to be neural-link, sticking electrodes into the brain. Creating the physical Star Trek Borg. I am Locutus of Borg. (We all are, to varying degrees.) We’ve already created the virtual borg, with facebook and twitter. We have not mastered the psychological dangers of social media, but whatever, full speed ahead, even if it means civilizational collapse. How bad can it be? The revolutions of 1848 show that it was worse in the past. And WWII shows it was much worse in the past. Whether social media is a greased skid into total collapse of Western Civ, or whether it is a ladder to greater heights of psycho-social attainment ... I don’t know. There are other thinkers out there, who have dug far more deeply into such questions. I’m not going to enter into competitions there.
So that leaves me in an odd state: trying to grasp something about the fundamentals of communication, while... I guess what I bring to the picture is physics. Which others do not have. Light cones and event horizons and all that. So maybe I should get back to what I was going to write about.
Or perhaps, there was one thread above, that seemed important that I flew by. Lets get back to it: the role of boundaries in establishing coherency of thought, coherency of ideas. Are these boundaries accidents of evolution? Are they fundamentally, physically primary? Does physics force is to have boundaries, like cell walls? Does physics force us to have disconnected minds, able to interact with one another only via low-bandwidth speech, movement? Or is it possible to have some undifferentiated borg-like neural-link? Well, saw open any modern CPU, and you see the von Neumann architecture: functional units, localized in space, with communications channels between them. This suggests that the multi-scale network is necessary. That computation necessarily requires multi-scale networks, where, at each physical size, there is some blob of highly interconnected, dense compute units, and between them are communications channels. Its not uniform, its blobby. And this recurs at all size scales.
Have I learned anything here that wasn’t already obvious? So the weird thing is that yes, perhaps I did. Its a form of anecdotal confirmation of an opinion I already held. But still...
Oh, I see what I am fishing for. So, in measure-preserving dynamical systems, there are concepts of ergodicity and mixing. And these concepts talk very explicitly about the route to uniform, isotropic distributions. And this does give us understanding of industrial processes: the bulk properties of liquids and gases, the mixing of aggregates in industrial mixers. But the thought-chain above says that we do NOT want to do this things to information flows. We don’t want to have a smooth blend of neurons, Jupiter-sized. We don’t build our CPU’s as uniform blends of transistors, with Zipfian distributions of communications channels. Present-day CPU architectures are much much blobbier than a simple scale-free network. The question of “what is complexity” is the question of “what sits in between unmixed substances, and pure ergodic/mixing uniform, isotropic distributions?”
The answer seems to be “everything”. Folded proteins are not random isotropic uniform distributions of atoms: they are quite the opposite. Galaxies under lambda-CDM are not homogeneous isotropic distributions of matter: one of the primary qustions of cosmology is “how did we get from the uniformity and smoothness seen in the CMB, to the lumpiness of the Local Group, the Great Attractor, the Dipole?”
So what’s the answer? Well, for the radiation-dominated universe and earlier, quantum field theory is needed. After that, the temperature drops, and it seems that only matter matters, that and the Einstein field equations. The blunt inference is to say “oh well, its just some differential equation doing it’s thing”. But also, the reaction-diffusion equation is “just some equation doing it’s thing” but it very explicitly time-evolves away from uniform, isotropic distributions. Using traditional language, the homogeneous, isotropic distribution is an unstable fixed point of the reaction-diffusion equation. Similarly, I guess one would say “an isotropic homogeneous matter distribution is an unstable fixed point of the Einstein field equations”. Is this an actual theorem? If so, the books on cosmology that I’ve read through have not yet mentioned it.
Shame that they don’t because it would provide a toe-hold. The point here is that isotropic, homogeneous mixtures of carbon, oxygen and hydrogen are also an unstable fixed point of room-temperature chemistry driven by non-equilibrium thermodynamics. And isotropic, homogeneous aggregates of transistors are an unstable fixed point of hardware engineering processes. Isotropic, homogeneous aggregates of neurons are an unstable fixed point of neural evolution. The processes driving this are wildly incomparable, but the attractor, pulling us to non-uniform multi-scale arrangements of matter is the same.
I said “matter”, but with some effort, I suspect I could find examples from the noosphere. Perhaps something about how academic knowledge is compartmentalized. There is a tight, highly-connected ball of facts in genomics, but this ball, this subject domain, is distant from the highly-connected ball of facts in French Lit. The distance between these two blobs is an ultrametric. The dynamical process pushing from homogeneous, isotropic states applies not only to matter, but also to ... knowledge.
Before Aristotle, we “knew nothing”, since then we’ve learned a lot, so there is a growth of knowledge. But I need to detangle the “growth of knowledge” from the “growth of complexity”. In the radiation-dominated portion of the universe, it is desribable with only a handful of parameters needed for the equation of state. No one is tracking individual photons, where they came from or where they went. Still this is ultimately some kind of approximation: good to maybe 20 orders of magnitude, but still an approximation.
Is it correct to think of cosmology since then as an amplification of non-uniformities that were already present in the plasma? Well, is it correct to think of the reaction-diffusion equation as an amplifier of non-uniformities? The mathematical conundrum here is stability vs initial conditions: the pencil balanced on its tip can, in principle, stay balanced forever. In this case, “forever” means “not forever in time” but “lets use a microscope and zoom in on the tip of the pencil” and what we see is not the scale-free network of rational numbers, but the scale-free network of real numbers: the continuum. The position of tip of that pencil (relative to it’s center of gravity, and the direction of the gravitational force) is specified to an infinite number of digits. ... or is it? The relative positions actually have to be zero, and is zero “an infinite number of digits”? Well, only if we use decimal expansions. Or p-adic expansions. Otherwise, zero is an exact number, with low Kolmogorov complexity.
What is the origin of the instability to a balanced pencil? In reality, it is air-gusts. In a vacuum, its micro seismic events. In an isolated cavity, its thermal fluctuations of the atoms at the tip of the pencil. Plenty of physical sources of noise that knock it off it’s unstable equilibrium. What about the “mathematically perfect” pencil? Well, using infinitessimals, rigorously defined, like surreals, a la J.H. Conway, for example, then one can ask: would a perturbation by an infinitessimal unbalance the pencil? Getting an answer to that requires extending the theory of ordinary differential equations to the surreals. This extension of the theory is an act of engineering, since there is probably considerable freedom in how one can glue the infniitessimals at a lower rank to the real numbers. I guess. This also pilots us back to the Borel hierarchy. And so that whole ball of topics, I find them very very interesting and I want to spend more time exploring that.
At any rate, what was the point here? The exploration of an unstable fixed point of a balanced pencil, set into a framework of surreals and Borel hierarchy, as opposed to the reality of wind gusts, seismic events and thermal motion of atoms.
What about the unstable fixed points of cosmology, biochemistry, computer hardware engineering or knowledge in the noosphere? I imagine that there is one ring to rule them all. its just that computer engineering and the creation of knowledge graphs are not described by differential equations, and so surreal numbers do not apply. A decade ago, or more, I concluded that this all has something to it all being “hyperbolic”. This is still a valid insight, but it needs firming up. Unstable points, e.g. in Morse theory, are hyperbolic. But hardware engineering and the noosphere are not manifolds, and so some generalization is required. Enter the jigsaw-puzzle pieces, but I do not have a graphical generalization of manifolds to jigsaws, and I do not have a hyperbolic interpretation of jigsaws, other than to say the number of combinatorial possibilities is unbounded.
That is, give a set of axioms, such as in model theory, the corresponding language is either finite, or infinite. In the case of the infinite language, this is countable-infinity and we get to it because of a combinatoric explosion of ways of recombining the axioms of the system. So it seems that combinatorial explosions provide the notion of hyperbolicity that I am looking for. I have not read anything that connects hyperbolocity on manifolds to combinatorial explosions. The obvious place to do these would be with sheafs (a la sheaf theory), rings, the bridge between rings and algebraic geometry provided by schemes. I always struggled with rings, though. Rings always break my mind. Not sure why. Maybe this is a monster I need to wrestle, a fear I need to overcome.I do have a copy of Eisenbud & Harris, “The Geometry of Schemes”. Perhaps I need to try again.
Anyway, nothing that i wrote above is what I was going to write about this morning. I was going to write about time. Perhaps this is a good time for that.
So, there are people who think that free will doesn’t exist, because they have a mental model of a deterministic universe driven by the inviolable equations of physics. The future is foretold, and we move through, like actors in a play. This founders in several ways. If the future is foretold, why not just zoom to the end? If we do computer simulations of hydrodynamics, we can reverse and forward, speed up slow down and halt that simulation, and take a gods-eye view of the simulation. If the physical future is foretold, then why not just have a gods-eye view of the cosmos? Why are we embedded inescapably in the here-and-now?
First, some evidence that the future doesn’t exist. Biology and evolution has invested a lot of effort to develop brains, which are, more or less, future-prediction machines. If the future was foretold, then why do we need brains? We could be placid rivers flowing, brainless, into the future. But no, complexity grows at the forefront of now, separating past and future.
Where do we search for the origin of time? A flowing river is indeed brainless, but it too seems to be caught in the present: it flows here and now, and yes, we use our brains to perceive it, but I think there’s plenty of evidence, say, from cosmology, that the distinction between past and future existed before there were brains and observers. I’m pretty sure the cosmos did not just zoom up to a solipsistic here-and-now, fast-forwarding through the steps that created the cosmic microwave background. I believe that there was a march of time, even then, before brains. And to imagine that it was only the advent of brains that forced the collapse of the past into being the past, well, again, that seems solipsistic. I reject solipsism straight out of hand. Although I admit there is a very interesting place in the universe for solipsism, because of the whole problem with qualia. I keep saying “spin glass” and “ultrametric” and Sherrington-Kirkpatrick” as an impressionistic allusion to the the multi-scale structure compartmentalization of pieces-parts and communications channels between them. In this model, solipsism is the ultimate qualia of the single isolated part, utterly disconnected from the outside world, except by sensory organs, imagining everything out there is a dream. Which it is, in some true and proper sense. That’s the problem with dreams and human psychonautics: psychoses allow us to think this way. But the presupposition is that there is something “normal”. Psychological normalcy is a slippery eel.
Where was I? I am going to go for a bike ride now, so I bid adieu. I was going to expand this essay, looking for sources that might tell us where time comes from. One obvious territory to explore is differential equations, but, in a sense, we’ve already beaten that to death. I think. Of course, there are differential equations with time in them, but that’s not where time comes from. We also have the non-differentiable, non-manifold structure of the noosphere. The noosphere too appears to be trapped in the here and now. Partly trapped: the noosphere remembers the past, so it has detached there. The noosphere has the future as an event horizon, but this is curiously reversed from the usual even horizons: the future is coming at us, like a white hole spewing. The here and now is the event horizon of things that have not yet come to be, the future that has not yet materialized. I want to explore this train of thought more, but the clock is ticking and the past asserts that going for a bike ride is a better use of my future, than to sit here and type more.
13 January 2025
Continuing from where I left off yesterday. The question is “why is there time?” or “why does time exist?” or “what is the physics that causes time to be a perceptible, sensible part of the universe?”
Before I restart, I want to make a short detour to the so-called “timescape cosmology”. The proposal here is that “time runs faster” in empty cosmological voids. Apparently, the Milky Way and the Local Group sit in the middle of a void. I have not read the 2007 original timescape paper. But I can guess: we know, from GR, that time runs slower in a gravity well. So, GPS satellites actually adjust for this, because they do not sit in Earth’s gravity well. This is a measured real thing (e.g. Pound-Rebka). How big is the effect, at the galactic scale? The 100 Mparsec scale? I dunno, I won’t back-of-the-envelope it (yet) and maybe someday I’ll read the paper. But...
But... so the philosophically daunting issue is that, even in empty space, “time runs”. The EFE eqns are “timeless” in that you have some matter distribution or some energy-stress tensor and you solve it and you get answers “for all time”. The de Sitter solution (no matter, no radiation, no fluids) is expressed with coordinate patches from an atlas on a manifold that “doesn’t care” that time is “running”. Time is just some abstract coordinate in the map. You can take *any* spacelike surface, and arbitrarily declare it to be the isochronous surface, so you have to have some argument as to what the correct one is. In cosmology, this is usually taken to be the last scattering surface for CMB.
Anyway, that’s a curious detour, but it misses the point. Let’s get back on track. We have three obvious sources of time: differential eqns, quantum field theory, and statistical mechanics. Lets look at each in turn.
Differential eqns have a time coordinate “built in”, so this doesn’t explain “where does time come from?”. Differential equations are usually first-order in time, sometimes second. In this sense, their “memory” of what happened in the past is very short: one or two steps (imagined to be numeric difference equations). Any “memory” further than that is recorded in the space-like directions. The canonical example is reaction-diffusion: it has a characteristic time scale. Simplifying, one can in general build diffeqs that have oscillatory solutions. If you have a collection of oscillators, you can hook them together and engineer dynamical systems that have complex time behaviors. This doesn’t explain “where time comes from”, it just says “if I have an identifiable time coordinate, then I can engineer complex behaviors”.
By convention, most oscillatory solutions can be embedded in the complex plane, via Euler’s eqn
, which perhaps clouds the issue. It shouldn’t: the complex plane is a special case of an almost-complex structure having some
with
and symplectic structures have such
’s as a general rule: this is just the “canonical one-form” or “tautological one-form” or “solder form”
that arises in symplectic geometry. And that arises because tangent bundles are symplectic, and so the argument could be made that “if you have a differentiable manifold, then you have a tangent bundle, and it is symplectic, and you have a
and thus can conclude that oscillatory ’things’ are a by-product of differentiable manifolds”.
There’s one more step: oscillatory ’things’ need to imply “time” somehow. So, manifolds with integrable vector fields on them will have integrable flows, and the parameter along the flow can be interpreted as “time”. If one can take perpendicular slices across that flow, you can call these “space-like” (even in the absence of a psuedo-Riemannian metric), and the flow itself gives a “local time coordinate” on that patch/atlas.
This construction of “time” from “integrable flows” has several issues. One is “how many vector fields are there that are integrable?” and “when are they homotopically equivalent?” or perhaps “when are they diffeomorphic?” If all of them are equivalent, then forward-time can be diffeomorphically deformed along a homotopic path to backwards-time, and so the resulting structure can’t really be called “time”. In physics, we want time to be an arrow, to be oriented. To have
in there, somehow.
At any rate, this seems like a not-bad approach. The question then becomes “what kinds of (differentiable) manifolds have integrable vector flows, where the homotopy group of the flows is
?” That’s a question that could be answered, I suppose. None of my diff topology or diff geom textbooks went that way, but also I was not paying attention, and not looking to answer that particular question.
A related question would be “when can those differentiable flows be given a Minkowski space structure?” and I guess the more precise wording for this would be “when does a manifold have tangent spaces that are Minkowski space?”. The obvious answer is to invert this, upside-down, giving the immediate answer: “any space with pseudo-Riemannian geometry”. This one goes full-circle, ending where we started, with a tautology. “Assume Minkowski, therefore time”.
There are curiosities on this path: e.g. the Godel solution for EFE, describing a rotating universe. It has closed time-like loops. More generally, there are all sorts of time-like vs space-like confusions marked by boundaries that are event horizons. Thus, perhaps we can loosen the conditions, and ask “do manifolds with event horizons necessarily have a Minkowski-space tangent spaces?” or are there other kinds of manifolds that have event-horizon-type structures? This question is not well-posed. Take it to be a poetic, inspirational question.
So that kind of exhausts classical physics. Yes, there are differentiable structures, wherein something in those structures can be given the interpretation of “time”, or can plausibly be identified with the physics concept of “time”. Fine. Great. It does not at all address the question of “Why are we trapped in the here and now? Why can we remember the past, but not change it? Why can’t we remember the future? Why do we think we have free will to change the future?” I utterly fail to see how anything in the classical theory differentiable manifolds can have any bearing on these questions. So punt on that.
Next on the agenda: quantum.
First, lets recap what quantum is. Its a thing with an action, where the action can be minimized with Euler–Lagrange or Hamilton–Jacobi, giving classical equations of motion. Close to these minimizing (or stationary) solutions, within one hbar of distance, are other (differentiable) paths/surfaces. They are necessarily differentiable, since the action has derivatives in it, and so non-differentiable paths/surfaces would result in an infinite (or undefined) action. The partition function is
so anything with infinite/undefined
cannot contribute. I belabor this point, because lots of fractals are non-differentiable everywhere. Such fractals often have perfectly well-defined measure theory behind them, i.e. are integrable, and so they can show up in measure-preserving dynamical systems. So, there’s a bit of unresolved tension, here: illustrating how differential equations (time-reversible ones, at that) give rise to measure-preserving dynamical systems and systems having an action. The prototypical “answer” is Sinai’s billiards, where each reflection is time-reversible, momentum/energy-preserving, but ergodic and non-differentiable in the limit. For now, that’s a step too far; see however below.
Anyway, changing gears. If one imagines replacing derivatives with differentials, thus discretizing the problem, then the differential eqn that gives a stationary point of the action can be imagined to be .. watch for it: a collection of jigsaw puzzle pieces, marked with tabs and connectors, stating how the differentials can be legally combined to given an expression for the action.
Are there two types of these jigsaws? One type, when assembled, giving the stationary solution, while others, with looser assembly standards, that give nearby solutions? There’s also a counting problem: the classical solution is a point. How many nearby solutions are there? What’s the measure?
The problem here is that we once again take a god-like view: there is a classical action, we know it for all time. We stick it in the quantum partition function, and again know it for all-time. We do not have an adequate theory for the measure of such systems, but so what: imagine we did: it affords us a god-like view, where we see not just the past, but imagine being able to see the future, too.
Many-worlds has a curious role here. So, on the one hand,
is meant to be an integral over all worlds, in the many-worlds interpretation. On the other hand, all of these other worlds are assumed to be like ours: predominantly classical, i.e. given as solutions to the classical action. But there is only one solution to the classical action, not many. So either we are wrong about the action, or we are wrong about “many”. That is, we either need an action with “many” classical solutions, or we are correct about our action (the Standard Model is correct) and we are incorrect about there being “many” solutions.
I propose one way out of this dilemma: time. At any given point in time, any “now”, we do not yet know which future will be the one, true, action-minimizing future. So we keep tabs on them all, “until later”, when we can “find out”. Think of this as a computer weather simulation: numerical integration results in numerical errors, but we wish to minimize those errors. If course, they can be minimized locally, by picking a finer grid, but better is to minimize them globally: say, minimize the root-mean-square of all numerical errors, across the entire simulation. This would require, at each “point” in the simulation, to track “many different worlds”, and then, at some point, select the one that minimizes the errors, thus “collapsing” the many choices to fewer choices. This collapse would probably have a forward-backward nature to it: interferometric, so different paths are pursued, and welcher-weg cannot be answered until “later”, when the paths are brought back together and summed.
In this interpretation, the many-worlds aren’t some mysterious “parallel universes, just like our own, but different”, but are rather an accounting trick, because we cannot actually minimize the action *right now*, we will have to wait for the future to happen, before that can be done. In the meanwhile, track a giant pile of possible universes. The “past” then becomes what has been resolved and frozen. The future remains unknown. This has aspects of the “transaction interpretation of QM” (TIQM) in that future events (results of interferometric comparisons) finally fix past events (that point where the split along the two arms of the interferometer started).
BTW, I should mention: TIQM seems to fit well with the two state-vector formalism (TSVF) and seems to be compatible with weak measurements (from what I can tell.)
This, the TIQM or variants thereof, would seem to indicate that “now” is not an infinitely thin space-time slice, but rather of finite width. And, not a fixed finite width, but multi-scale. Small interferometers can be resolved in femtoseconds, bigger ones in milliseconds. e.g. the Alain Aspect experiments look at phenomena where the collapse is delayed for milliseconds. That is, the Aspect experiments probe “now”, where the width of “now” is milliseconds. The shmucks working on quantum computing are suffering because they want to create complex states that remain entangled for seconds or longer. They talk about “thermal noise” collapsing their systems. They are partly right: yes, they need to build systems that are isolated, insulated from the rest of the universe, and all the thermal fiddle-faddle. But the microscopic model needs to be that some “photon” from the outside world came in, bonked your superposition, which is bad but not fatal, but then another photon left your superposition and bonked the external world, which is fatal: you now have the two arms of an interferometer, and one arm of the interferometer is tangled into the universe, the other is tangled into your superposition, and so, kaboom, your state collapses before you get the chance to actually accomplish any meaningful quantum “computation”. This is the engineering problem that is “well-understood” that everyone in the industry “groks”. What I’m trying to do here is to argue that a TIQM type model is actually the correct model. This should be relatively non-controversial: there are many legit physicists who believe in TIQM, even if they are a minority. I’m trying to explicitly rule out the cranks and shysters. I want nothing to do with “prolific entrepreneurs” who use ChatGPT to create incoherent “scientific” rebuttals to the controversy of the day. I read one yesterday, a rebuttal to the Timescape Model in cosmology, and it was shameful. For a little while, I thought it might be a grad student who was going to make a valid point. No. It was a “prolific entrepreneur” with a shoddy cut-n-paste job.
My reasoning in the last ten paragraphs may also be incorrect, but its not shoddy. I am taking the utmost care to be clear and direct and accurate. The result may still be a dazed and confused wall of words, but ... I’m trying. This is my best shot. (My best shot in the allotted time. The clock is ticking. The race into the future is on.)
OK. I think that kind of exhausts the quantum side of things. It does sketch why there is a “here and now”, and it does answer why the future is unknown. The future is unknown because some CMB photon could arrive on Earth, and do the butterfly-effect thing. Or worse: some primordial neutrino. Until those neutrinos pass by, and do their butterly-effect thing, we cannot know the future.
Careful: the standard retort here is that its “small and negligible” which is perfectly true for determining if the Flatiron building in New York will fall over and crush some pedestrians. But I’m philosophizing here: the integral
includes everything, including primordial neutrinos. They may have negligible effects on practical calculations ... they *must* have negligible effect, as otherwise practical calculations are impossible. But from the viewpoint of “why are we trapped in the here-and-now?” I cannot ignore their contribution. I don’t have some explicit calculation where I can say “it’s negligible”. Hmm.
The above reduces quantum many-worlds to a book-keeping device, the books for which cannot be closed until “later”. But it also makes things very mechanistic: some primordial neutrino has some effect. Sure, we use complex numbers, etc. to perform that calculation; the conventional theory is what Kamiokande is built on. Rather, what I’m doing is to reduce many-worlds to a many-body problem, a statistical-mechanics problem. Yes, its “statistical mechanics with complex numbers aka quantum field theory”, but I’m trying to remove the “woo” of “parallel universes” and instead have a kind of boring common-sense “its just an accounting trick” that only accountants understand.
I’ve written before in this diary about how math is hallucinatory. That’s plenty, baby. I do not need to also have my physics be hallucinatory. I’m fine with hard-headed common-sense no-nonsense cut-the-crap accounting tricks, instead of “woo” and “mysterious interdimensional gods playing dice with the universe”. Just had to get that out of the way, didn’t I? I’m glad no one is reading this. I can see a lot of thumbs-down icons being clicked right now.
Anyway, all of the above now necessitates getting into the third leg: a review of many-body statistical mechanics. Mostly, in this section, I will recapitulate everything I learned since the day I met Dean Driebe, and how he told me he could explain the arrow of time with the Frobenius-Perron operator. And this is an important insight. And mainstream physics even got a bad case of “Koopmanitis”, cause everyone saw that this is an important insight. So in my recap, I will try to imagine how Ruelle-Frobenius-Perron can be reconciled with QFT, wave function collapse (a la TIQM) and see if it provides insight into the prison of “here and now”. But first, I take a break, because (a) its dinner, and (b) there are other things I should be doing, and need to get done. So maybe till tomorrow, or later.
Oh, before I break: there is a rather stark issues that arises with timescape cosmology. So, with conventional Frobenius-Perron (FP), the language is of ergodic theory. The canonical physics model is gas-in-a-box. And that’s fine. But what about empty space? How is it that “time is running” in “empty space”, when there’s no matter, no atoms in it? Well, two answers: (a) even in cosmic voids, one can expect to find one hydrogen atom every ten cubic meters (ts like one per cubic meter. in cosmology, on average, but most of those are in galaxies, so presumably the cosmic voids are a few orders of magnitude down from that.) So the voids aren’t “really empty”. They also contain thousands(?) of CMB photons per cubic meter, and almost that many (non-interacting) neutrinos, so even these voids aren’t truly “empty”. They also contain a bunch of (non-interacting, pressure-less) cold dark mater. Is this amount of non-emptiness sufficient to make an argument about ergodcity and Frobenius-Perron? I don’t know. Alternative answer (b) is quantum zero-point fluctuations. Given that these are off by 120 orders of magnitude, it’s perhaps moot, but it does give an opportunity to head-scratch and wonder “what is the mechanism that wipes out quantum ZP from cosmological lambda?”
The point here was supposed to be “Is it possible to have a here-and-now in ’empty’ space?” because there’s no subject/object in empty space that can perceive time. Because we can zoom out and take the gods-eye view of empty space, slap a coordinate chart on it, and be utterly lacking in the ability of saying “this is where ’now’ is”. What we can do is to define comoving coordinates relative to last-scattering, and use that to define “now”.
Oh, fucking footnote time. We have Schrodinger’s cat, whose wave-function collapses when Wigner opens the box and looks at it. We have “Wigner’s friend”, who then enters the room. This provides an anthropocentric argument that astronomical telescopes cause the collapse of wave-functions in 100 mega-parsec-distant voids. I fucking hate these anthropocentric arguments. But it does get across the point that large-scale quantum entanglements are participating in the time-evolution of the universe, even if they are negligible in any practical calculation.
Sigh. Shit. Seems I will have to look up and read: David Wiltshire, 2007 New J. Phys., 9, 377 and also Phys. Rev. Lett., 99, 251101 and then references to Thomas Burchert 2000, Gen. Relativ. Gravitation, 32, 105. This is so fucking far away from answering “why does the universe contain a combinatorially explosive number of electrical engineering circuit diagrams?” but then, I am looking for “an answer” to “why does the complexity increase everywhere?” so if I can’t do it for empty voids in cosmology, then, in a sense I’ve failed. Well, I will fail. I can’t imagine this is an easy problem. But why not? I’ll throw my hat in the ring. I doubt anyone else is venturing here. May as well be me, to sacrifice myself to the gods of the void. Mixed metaphor: “when you stare at the void, you may find it staring back at you”?
The Wiltshire/Burchert idea: Burtchert defines averaging. He or Wiltshire note that walls are spatially flat, voids have negative curvature. Some quotes: “a substantial difference in clock rates arises cumulatively over the lifetime of the universe from the tiny relative volume deceleration of voids as compared to wall regions (Wiltshire 2008). The magnitude of this relative deceleration, typically of the order of
... apparent acceleration is only registered once the void fraction reaches a critical threshold of 59 per cent, typically near a redshift z∼ 0.9 (Wiltshire 2007a) ... voids (typically of diameter ∼30 h−1 Mpc and smaller) ... Large gradients in Ricci scalar curvature are assumed to exist between the walls/filaments and the voids, consistent with observations that the latter have density contrasts close to δρ/ρ∼−1 ... The Hubble ‘constant’ inferred in this manner should peak at the dominant void scale 30h−1 Mpc, i.e. at z∼ 0.01, with a maximum value up to 17 per cent greater than the global average and then steadily decrease to near the global average value when the scale of statistical homogeneity is reached. ... the scale of statistical homogeneity represents a redshift of the order of z∼ 0.033, ... ” The above is from Supernova tests of the timescape cosmology , Monthly Notices of the Royal Astronomical Society, Volume 413, Issue 1, May 2011, Pages 367–385, https://doi.org/10.1111/j.1365-2966.2010.18142.x https://academic.oup.com/mnras/article/413/1/367/1062339
The intro provides a summary sufficient for my purposes. So maybe I won’t have to read anything else. The upshot is that our wall is moving away from other walls faster than average, because there is a void in the middle. Things average out, though the farther one goes. Expect to see average expansion rates at
and faster expansion rates at
0.01. Clocks in the walls run slower than clocks in the voids.
Related is the idea of the “Hubble bubble”, that the Milky way is in the middle of an underdensity of mass. This gives another reason to exclude low-z SNIa data.
So here’s the deal, now that I read the whole paper. The timescape idea is a collection of formulas that explain how to compute cosmological parameters, due to inhomogeneities, at scales *larger* than than our local void or supervoid, or, more precisely larger then
. At those higher z’es, there are still voids and walls, but now there are enough of them that meaningful averages can be taken over them. Thus, data cuts are needed: exclude nearby SNIa that are in our known local inhomogeneity region, and use the *correct* formulas for averaging over inhomogeneities at farther distances. This makes sense to me. Go out far enough where you can take meaningful averages, and then use correct averaging formulas. Doh! This is a pretty solid argument, even if you are a firm lambdaCDM believer. I mean: treat your data correctly. Who would argue against that? So I close the chapter on timescape. I get it. Cool. Crank the data. See how the fits work.
Whatever. None of this gives any particular insight into “why is there time?” The idea that comoving clocks run faster in voids is quite intriguing, but does not seem to shed any light on the question of “why is there a ’now’”?
I guess I could go off on another tangent: atomic clocks. But I’m thinking this is also unilluminating: these provide quantum systems that are exceptionally stable. They measure the passage of “now” which is necessarily related to the centroid of our non-zero width thermal-entangled quantum-now. That is, we live in a thermal bath of quantum entanglements, and so I would estimate the thermal with of “now” to be given by
and
and
and so
so that’s 100 femtoseconds or a tenth of a picosecond as an order of magnitude expression for the width of “now” in our ordinary world. Note that atomic clocks like to bring the temperature down (e.g. cesium fountain) and the stated reasons and physical principles never use a language like “the width of ’now’”, but effectively, this is the interpretation that should be given. Heisenberg uncertainty is meant to be a manifestation of what Fourier transforms do to waves, and that is all well and good, but the fact that some experiments have to deal with thermal motion at the same energy scale suggests that we don’t “really know what time it is” at that scale. Yes, the atomic clocks do provide a value for time, but that time has to be interpreted as the centroid of a smeared-out time that room-temperature solids and liquids possess.
This includes water flowing in a river. The hydrodynamics happens at scales much larger than the atomic femtoseconds. Time may be uncertain at the femtosecond layer, but the “now” in a river may as well be instantaneous. Wigner’s friend is not required to make the wave-function of a river collapse; it does that on it’s own. I can make accurate predication about a river if I use hydrodynamics, a length scale longer than a nanometer, and a time scale longer than picosecond. Get much smaller than this and quantum effects start to matter. This is all painfully obvious and a rather blunt, But it does serve to illustrate what I mean by “the width of now”.
For table-top sized optical interferometers, or for razor-blade optical double-slit experiments, different values of
manifest, and this is what I mean by “multi-scale”. The “width of now” depends on sizes, and the degree to which one can provide lab conditions that isolate quantum effects from ambient thermal noise. Not an accident that atomic physics is done in a vacuum.
What’s the “width of now” in a cosmic void, with some thousands of CMB photons per cubic meter, and far less than one proton per cubic meter? According to my hand-waving above, it should be related to the mean-free-path of those baryons, maybe. But if I could stick an actual physical clock into that void, the “width of now” in the clock collapses to femtoseconds, and the clock would work just like it does on the lab table. Without that clock, I’m suggesting that time behaves like the ancient philosophical brain-teaser: “if a tree falls in the forest, and no one is there to hear it, does it make a sound?” That answer is “yes, time does tick and advance and move forward, even in a vacuum, but time moves forward only to the degree that there are thermally quantum-entangled baryons and photons there to witness the passage of time. The quantum-entangled baryons pull in a factor of
, until something makes them decohere and wave-function-collapse, which has to happen at some thermodynamic Boltzmann
type of timescale. Perhaps truly, truly empty space doesn’t know what “now” is. We can slap a coordinate system on empty space, but we can’t point at where “now” is. ... heh. Except interferometrically. We can define initial-now as the space-like time of last scattering, evolve it to “now” today, define co-moving coordinates and then make the claim that “now” in a void is what the comoving coordinate for time would be if we parallel-transported our clock along this path, from here to there. And we can even argue that this is necessarily the right answer, because we have validated GR and know how this stuff works. The “now” over there is the same as the “now” here, even if the “width of now” there is wider than it is here. The parallel-transported, Hubble-expansion-corrected “now” line up as expected. Yes, trees make a sound when they fall.
None of these ruminations have shed even the slightest iota of enlightenment of what “now” really is. Other than some claim that “textbook physics is enough” and hand-waving about Frobenius-Perron. That, and a denial that Wigner’s friend is needed to make “now” happen. I’m chasing my tail.
14 January 2025
Chasing my tail hard. Obvious flaws with the above: it creates a tension between geometric (gravitational) time, as the proper length of a geodesic, and some quantum time, which is obtained via quantum speed limit theorems. Given that I wrote/rewrote maybe half the Wikipedia article on the quantum speed limit, you might think I’d know something about something here. But no, I’m senile. There’s simply something in here I just don’t understand. I suspect that’s because I don’t understand the thermodynamics behind Hawking radiation. So that’s a to-do item.
15 January 2025
My personal qualia of “right now” aligns with that of other people, and indeed with other animals, and certainly high-function robots, and, looking through microscopes at killer T-cells chasing down microbes indicates there’s a “right now” for them that coincides with my own personal qualia. We are all in exactly the same flat space-time surface. Looking at GPS clocks on orbiting satellites, it seems entirely reasonable to say there’s a “right now” for them, that corresponds with my own, after general-relativistic corrections for the gravity well I’m in (and they’re not). So “right now” appears to be GR-precise. It’s always proper time.
What this means is that I cannot derive “right now” from quantum speed-limit theorems (alone), as these would seem to depend on the local matter density. For example, QSL’s are saturated by the qubit, but the actual delta-t is in relation to the two energy levels in the qubit. These could be “anything”, and for gas-in-a–box, these would be temperature-dependent. So I need a QSL that does NOT have thermodynamic origin. The only thing that flies to mind that would satisfy this, is zero-point energy. It’s pervasive, its everywhere, including cosmic voids.
The first calculation to attempt would be to write down Unruh or Beckman or whatever they are called “squeezed states” (the coherent states that are twisted off) and attempt to find an expression for the QSL for such states.
I want to do this *right now*, but have other things I need to do today. So ... Toodle-oo.
16 January 2025
Or it is possible that many-worlds really do exist. This would require the the action that minimizes the partition function to have a tree structure. Which to me sounds crazy, because I’ve never seen any such, and it would be a black swan. But I can now imagine an analog: the beta expansion. To be clear, this one:
where
is some real number,
is another real number, the base, and the
are binary bits. Then, depending on
and
there are often many, infinitely many different bit-sequences which satisfy this relation. What’s more, the bit-sequences can be arranged in a tree: i.e. identical up to a certain length, and then they diverge. There’s even a phase transition, located at
the golden mean. I’ve written multiple papers on this.
Anyway, if
can be thought of as “minimizing something” (i.e. the action) and
is some fixed “cosmological constant”, then the collection of
are the “world lines” of observers, forking where forks are possible. So this is some zero-dimensional inspirational example of many-worlds. Note that the binary digits are generated by iterating
and so there is a folding-back. In some hand-wavey way, maybe this folding-back resembles the reflecting boundary conditions for AdS. Maybe that’s why you can do QG models on AdS. Wild guess.
So the above is a simple model of a branching structure. If instead, we insist that, no, there is only one “reality”, then the branch points can be interpreted as points where free-will gets a shot. That is, free-will is deterministically constrained, up until those branch points. Note that the
–expansions are also deterministically constrained for certain run-lengths, before a branch-point appears. The average run-lengths depend on
. There are also “univoke”
which allow only one unique expansion. The
expansion has a surprisingly complicated dynamics.
At any rate, this allows me to back of on insisting that “many worlds don’t exist”, as it now gives a plausible (to me) model on how they could happen.
Oh wait, there’s even more to this analogy! So, the “unphysical” thing about
dynamics is the folding: it connects and mixes together “distant regions”. But that’s what photons do: they take something way over there, and transport it to here, altering the reality here upon arrival. Pseudo-Riemannian geometry is weird.
I dreamt last night about our 3D reality as some sea-foam surfing at the tip of an ocean wave: we, too busy in our daily activities, churning like that foam, oblivious to the mass of water that carries us along. Only sometimes looking back at the wind-streaked trails left behind. It was thrilling. Almost an ecstatic vision of truth and reality, sublime and supreme. I dreamt many things last night, and the above is perhaps the simplest to explain and the most poetic. I could do a long analysis of my commonplace garbled dreams. They’re complicated and twisty.
For example: just before hopping into bed, I listened to a song on youtube, and read the comments, where many said “this song is sublime and supreme”, calling it transcendental, and using other superlatives. And oddly, I agree. The song is ’Stand Inside Your Love’, Smashing Pumkins. When I listen to it, it is very much a transcendental mystical experience. Now, many of the comments call it the ’best love song ever’. But they never ask ’love for who?’, implicitly assuming another human. On my first listen to this song, for the first time ... it was clear that Billy was singing about Jesus, or about God, that this was a paean to God. So of course it’s transcendental. Who wouldn’t want to stand inside your love?
And so my dream of our 3D present reality, the here-and-now, as the active foamy front at the edge of time, feels ecstatic, but I’ve got echoes of an ecstatic song tumbling in my mind.
See? I could go on and on. Why does this song provoke a transcendental reposnse, and other songs, say Volare, don’t? Well, the lyrics, for one. The pacing and dramatic breaking. Something about the neurophysiological structure of the brain allows transcendental experience. What? And how does this tie into our 3D world? Because Our 3D world is not “just” three-dee, its got massive patterns, inter-relationships, graphical nets in it, and some of those graphical nets qualify as being “transcendental”. All this blows my mind. I find it all just amazing. Stunningly so. I want to stand inside ... well, I am standing inside, we all are, aren’t we? Great. Now what? Time for another cup of coffee? Fuuuuu....
19 January 2025
Can’t sleep. I get these bouts of insomnia that come and go. They’re not cyclical, and I haven’t figured out what triggers them. Too much coffee? Late night snacking? Something else? Probably too much coffee.
Several ideas churned. The Painleve chart says that the fabric of spacetime falls into anything massive. This includes point particles e.g. baryons and electrons. The Higgs mechanism says electrons get mass through the Higgs field. Why would this coupling cause spacetime to curve? The baryons get their mass from confinement. This is an even bigger effect! Why would confinement bend spacetime? The previous diary entries above deduce that the wall of time is a zero-point effect hinged on the QSL. But zero-point is some ergodic many-body process I don’t understand. There’s some knot that ties these topics together.
Meanwhile, Owen says that he might get Stephen Wolfram as an advisor on some business venture. So of course, he has Wolfram’s fat book on his coffee table. I effing hate that book. I’d love it if it was undersold, but its oversold hype. The meanest thing I can think of saying is that Wolfram slept through the part of class where they explained Newton Differences. WTF. The over-selling just makes it cranky. It would be compelling if there was a Minkowski-covariant definition of cellular automata. Arguably, this would be possibly acceptable for the wall-of-time idea. Zero-point is some Minkowski-covariant (invariant) ergodic process. I don’t understand it. I do understand conventional QFT; I do not understand how it becomes ergodic. I understand the Bernoulli process, I don’t understand how QFT is Bernoulii-like. I understand tensor algebras. Is the ground QFT state supposed to be some coherent state defined on a tensor algebra? Is that what it is?
Is it possible that gravitation drives weak mixing? That weak mixing is a root cause of entanglement? The conventional answer is a flat-out no; entanglement is just the algebra of representation theory of simple Lie groups, and specifically the representations of su(2) and/or sl(2,C). Fine. But why is there entanglement between oscillators in different parts of space? Why is flat space Euclidean, with the standard topology, instead of a collection of points with a fine topology? What causes different points in space to couple, causing the fine topology to collapse into the standard one? The conventional answer would be “derivatives”: you can’t form a derivative on the fine topology. So that converts the question: “why are there derivatives?” Derivatives couple neighboring points. What causes that coupling to happen? This is partly what the Wolfram idea is about. The problem with Wolfram is he chucks the idea of a derivative out the window, but commits a greater crime of assuming a square lattice-grid topology. God-knows, maybe he’s moved on to hexagonal grids, or even sphere-packing grids. I ain’t gonna read that book.
If you’re going to discard derivatives and replace them with cellular automata, then what’s clearly needed is some definition of cellular automata on some random grid. That random grid has to course-grain into 3D space (and I guess that’s what the Planck-scale loop quantum gravity (LQG) people are saying. I have not read their stuff, either.) But this should be a generic topological trick: define some random graph, and show that it coarse-grains to n-dimensional Euclidean space with the standard topology. (Locally flat; we use that as a tangent space for “real” Riemannian geom. and/or symplectic geom.) Then we get lost in the weeds. Conventional algebraic topology tells use about singular homology. So we do some singular homology on this random grid, and get ... what? Famously the watchamacallit theorem says that there is no one-to-one correspondence between tessellated surfaces and continuous ones. But maybe that doesn’t matter.
An additional point of confusion: If I’m working with random graphs, I guess I’m supposed to be working with ensembles of such graphs? The ensemble is needed to provide averaging properties. The random-graph ensemble replaces the ensemble in the QFT functional integral. That is, instead of having
with
some field over points
for some space(-time)
, we instead sum with
for random graphs
in an ensemble of graphs
. We then work with the singular homology for each
to determine the dimension of the space. i.e. homology groups need to vanish in all dimensions except the desired dimension. Or rather, its OK if they don’t vanish for some of the
but, when averaged over all of the
they do. So that for a singular homology
for a graph
we construct
where
is some normalization (playing the role of the partition function.) Maybe I should use a different notation than
to avoid confusion about using
for cycles.
Several problems with this idea. First, in flat space, all homology groups vanish. So this trick doesn’t actually tell us what the dimension of the space. (Unless we redefine the problem to say something like “we’re looking for spheres”. But that would be stupid) So that’s a big fail. I fucked up in saying “homology”, I need some other construction that measures something that looks like dimension. Second, to have a meaningful sum there should be some action
so that
. This differs from conventional Ising-model stuff, in that we are summing over all graphs
and not over all field configurations on a fixed lattice. But what’s
? Where does it come from? What value does it take? Why?
The weight
is understood to provide a measure-theoretic-like measure for each
. But, when doing the transfer operator for the Bernoulli process the sum arose from working the ergodic map backwards, i.e. the root origin of the
came instead from a
which I wrote wrong, but the weighting is given by a Jacobian. I’m trying to capture the generic ergodic process idea and tie it back to “where does the action come from”? and reformulate “the action” as the “log of the Jacobian”. I’m confused. Why have I not tried this before, in my formal work? Probably because it was unenlightening for those simple cases. Maybe I didn’t spend enough time thinking about how and why it could be interesting. I should go back and try some force-fits of this idea and see what happens.
We can now hand-wave our way to the goal posts. For each vertex in
place some cellular automata there, and let it interact with neighboring points in some way. These interactions provide some value for
and then, given appropriate interactions, we find that the dominant contributions to
are given by graphs that coarse-grain to an n-dimensional Euclidean topology. Or maybe 3+1 for all the space-time nuts out there.
What have we achieved here? Well, *maybe* it provides a path from random grids to flat space. But the fact that there’s a sum over an ensemble suggests that the resulting space will be “quantum”. So I guess I’ve invented “quantum space”? And we do want “quantum space”, and I’m assuming that the LQG people have developed some technology that replaces my hand-waving with something more precise. My only quibble with LQG is that it should work for spaces in any dimension, not just Minkowski space, but genericaally for any space with a metric with signature (m,n) (i.e. for any Riemannian or pseudo-Riemannian space). If you want to say (3,1) is special, then the specialness has to come from somewhere else.
To conclude: maybe one can take ensembles of random graphs, and define an (arbitrary-dimensional) “quantum space” that way. Seems plausible. But this leaves the question of “why are we trapped in the now?” unanswered. Which does seem special to 3+1 especially given the weirdness of how propagators for the wave equation work in dimensions other than 3+1.
I dunno. This is a train-wreck of ideas. They all might actually be good ideas, but they all require some huge amount of work to refine and define and formalize and make exact. And me being lazy, I’m looking for the silver bullet.
24 January 2025
Back to AGI. For the last several days/weeks (month?) I’ve been trying to reconceptalize similarity measures. I’ve got jumbled ideas, none of them want to gel, and I can’t write them into a project README because they are incoherent. However, this diary is a safe space for incoherent ideas put forth by snowflakes who fear public perception when voicing their most private thoughts. Not here, buddy, we love you. You can ramble incoherently all you want. Let it out. Lit it out of your system. Let it all come out. We love you.
So I could jam the basis elements for a sparse vector into some new atom, in some c++ set but why? the atomspace already provides container-like constructions. But we don’t want sets, we want membership. But membership is rather fat: millions of new links. Atoms are a bit pudgy: 713 bytes per atom for one recent dataset. Keeping this in a C++ vector could be as little as 24 maybe 48 bytes/atom.
On the fly lookup could that work? Because we maybe we don’t need to keep anything? But we do, cause on the fly is slow. Esp if using the query engine to do the on-the-fly stuff.
Whats a vector embedding anyway? For the word-pairs, there were explicit links to left and right, and a wild-card in either gives the vector. For generic patterns, those patterns would need to have exactly two variables. Thence confusion: because we are using the wild-card to define the embedding, and also to fix the other side. These two distinct roles are mashed into one. Can they be detangled?
Sort of. For an embedding to work, all vectors must share the same same basis, as otherwise they are incomparable. Sof ro that a single-variable pattern suffices. Well, no: still two: one variable as wild-card, and the other one fixed to the item, because this is how we guarantee that the vectors have the same basis.
Word-pairs exploited a loophole of left-right conjugacy: instead of having one pattern with two distinguised slots, there were two patterns, with the second just being the symmatric transpose of the first, by accident. This is a happy accident, but cannot be taken to hold in general.
Well, except that it must. Somehow it must be transposable.... which brings us back to the start: it must be a pattern with two slots. OK, fine, I guess we can work with that.
So I’ve got a pattern with two slots. A typical task is the cosine similarity, i.e. dot product, so take two items that are to be compared, stick them in the lefft slot of the pattern, find wildcards, multiply.
Two problems: one where do the weights come from? (assuming non-uniform weighting) so pattern also has to indicate how to get a single float, or maybe something more complex. So this is not just a pattern, but also a key. And since the thing on the key might be a vector, a vector offset. Since it might be more complex than a vector, it needs to be some generic pattern for accessing something in the value, and then also making it clear how to multiply the said thing, pair-wise. So a pattern that takes a pair of values and returns a single float.
A single float because that’s all we can hope for in similarity. We are not asking “how are they similar”, but instead “how similar?”
A different problem is normalization. We can run the search pattern for A B being two different leftvalues, and find right-value wildcards, but there may be more wilds, both absent in A,B. So we need to run the full search comehow. And this could be horridly cpu-bound. So the result should be cached. But maybe its OK to run this in parallel, and just keep a running queue. Well, two running queues, one for left one for right. And I guess sets would be ok, it does have to be lists, and deduplication would be nice, since search will hammer lots of duplicates.
So the plan is, start the dual-wild card search. Keep left and right groundings on two distinct but well known locations on the pattern. Allow access to them, even while the pattern is running. Allow multi-threaded access. OK, that all works and is straightforward in the current query engine implementation.
The sets are not atoms, so will not be bloated (will be smaller). That’s fine.
So all we need is two well-known keys on the pattern. And a modified pattern traversal that know to put things there. So a new pair-wise query atom. OK fine. easy, not bloated. Acceptable, not paradigm breaking and not slow and not bloated. So green light all around.
That’s just part one, though. Part two is the weights. There are other parts, including GPU concerns, and including stream processing concerns. Those go on back burner. One thing at a time. Lets make sure we’ve got part one done:
– a new query atom with two slots. The slots could be either well-known names like (Prediate “left side”) and (Predicate “right side”) or they could be the left and right variable decls themselves. If left and right variable decls, then either the bare variables, or the variables with the type signatures. With type signatures might be best, because these are easy to find in the pattern: they are necessarily at the top.
– what else? Is that it? did we miss something? Can I prototype this on the file system? Yes, the file system provides a new an unique and different dataset that hints at disclosing new difficulties.
one of these new difficulties is a recursive similarity. Hold that thought. Lets complete the first part.
So, we can do this for all searches: doesn’t have to be two-variable, could be n-variable. The well-known location problem is solved, as well. Why didn’t I do this years ago? Shit, I want to code this *right now*, its clear as a bell. Obvious.
Fuck it. I will code this right now. That way, I don’t have to think about two things at once. hill climbing one step at a time. Get this done, then take the next step.
The hard one will be the gpu step, but that can’t impact conventional search.

Post script to above: I did go off and do it right away, and it works great. Again, why didn’t I do this years ago?
Two ideas I want to jot down, before I forget them. The first starts with the Minkowski Question Mark. It has a lattice model, and it is an infinite-range lattice model. I wrote it down some decades ago. But I’m thinking this is a Hopfield network as well. And so I’m thinking that maybe some of the famous properties of the question mark reappear as properties of neural nets, more generally. The interesting ones being those of differentiability.
More generally, if we have high-dimensional hypercubes, extremely long bit-strings, these are ... strings. and strings are one-dimensional, and have 1D lattice models. Sooo ... well, the Minkowski question mark model when I wrote it down , had a infinite-range interaction. Did I screw it up, and fail to recognize this as a local lattice model e.g. i.e. nearest-neighbor interactions, e.g. an Ising model, on an infinite-dimensional lattice? WTF. I have to go back and look at this again.
More generally, when do long-range interactions correspond to short-range interactions in higher-dimensional models? The problem is its late at night, and I’m tired. But I had to jot this down for later exploration.
The other idea was about employing frames and locals for a description of the thin layer of “now”. As I go to write these words, it is awfully empty-sounding. But when I got it, it seemed full. F;rames and locales are the correct approach. I think I have a book on this. Peter Johnstone, called “Stone Spaces” I have to read it again. I only got a little ways into it, last time. This time, go deeper.
Fuck all, too many interesting things out there, not enough time.
1 February 2025
State of being. Downtime. 8PM. I feel ... tired, exhausted, drained. Can’t do anything, don’t want to do anything, too early to sleep. Oddly, writing is perhaps something I want to do.
Set and setting. Did a lot of walking (about 2 hours worth) yesterday, my legs hurt. Bicycled 2.5 hours day before. Today was Saturday, a day to take off from manic coding. Read a marvelous physics paper: cosmology with torsion. Just fantastic. Apparently, Einstein–Cartan–Kibble–Sciama (ECKS) Theory makes torsion dynamical, and does a minimal coupling to spin. The result is that, in the action, the spin coupling is just algebraic; no derivatives, so it does not propagate. The torsion field is non-zero only where the spin is non-zero. The result is a theory which looks exactly like conventional cosmology, except that it has some small corrections to the energy-momentum tensor, and to the pressure, that are negative. By “small”, suppressed by a factor of G so truly very small. The terms are significant only when fermions are extremely dense, far greater than neutron stars. Basically, before the era of neutrino decoupling during quark-gluon recondensation. Plugging through the current neutrino density into FLRW he gets ... well, I’m putting the cart before the horse here. The idea is that there’s an era where the dominant force is a repulsive torsional force. I’m imagining a kind-of Pauli exclusion force, but its not that, because its not a flatspace thing, and its instead a term in the action. But I digress. Plugging in current netrino densities, he sees it being dominant when universe is one micron across, some 1e-43 seconds, when the “a” flrw term has a logarithmic correction, universe undergoes rapid expansion, with antipodes moving apart at 1e6 c and an effective expansion of 1e63 so more than enough to obtain fine-tuning. Also he claim right befoe this is high-viscosity, huge tidal forces, so very strong mixing resulting in homgenization. So basically, everything that scalar-field-driven inflation gives you, but without the scalar fields. Awesome idea, I’m buying it hook, line and sinker.
More, because he posits this also prevents formation of a singularity, with the repulsion due to torsion bouncing things before the singularity forms. Now, this is just a short 4-page-long Phys. Lett. so “the singularity doesn’t form” is a Shwarzschild idea, and not a Kerr idea and I can say I’ve never read about the collapse of a rotating star, and the formation of a singularity there, and of course the Penrose diagram there ... blah blah ring sinularity but clearly difficult to visualizes. Anyway, author of paper posits that every newly form BH has a universe on the other side of it.
I wonder how this squares with the mass-inflation models from what’s-iz-name ... which are built on top of the conventional interior solutions with some low-density infalling dust ... then there’s that wonderful river model ... so if I did not have to eat, sleep or be subject to some of the basic constraints of human existence, I could easily go into a manic phase trying to work on this stuff. But reality affords no such luxury: its now almost 9PM, and between now and midnight, what could I get done? Nothing.
And honestly, thinking is a mental chore, and I don’t feel like doing anything because well, I’m exhausted. Seems that I lie doing more than reading. FOr example, I’d rather write, here, then read.
Then there’s all the “I should be doing” stuff. Like “I should be” thinking about AGI, but I’m stumped, a bit. Some creative block. Which I am rechanneling into thinking about physics.
To relax, I was going to read pages out of Robert Hughes “The Shock of the New”. I’ve been reading random paragraphs out of it, random evening for the past month, and its a fun book to read! and I sat down to read it just now, and my brain clouded over sand said “writing would be more fun than reading.” So here I am writing. When in fact ... Now I have the urge to go fuck with the rotating river mode, and try to line that up with the torsion thing, and redo all that with everything I know about spin connections, etc. try to get some unified view ... and for what? I could actually do this, and it could actually be fun.
Everything beckons. Everything says “Linas you should go manic on this, right now”. I’m not manic depressive, but I understand the general idea intuitively. I want to go manic, but I’m already exhausted before I even start.
For example, I could/should copy the torsion-spin coupling equations out of that paper, but fuck-all, there’s already a notational issue in there that needs work.
Crap. There’s a list of things “I should be doing”, but I so don’t feel like doing them. I am wasting my time writing, here. I need to just fuck around for a few hours, and then go to bed.
1 February 2025 Redux
The above are some vague complaints about mental exhaustion. And I really really want to copy those formulas for the dynamical torsion to my other physics diary, but fuck it. Instead I am going to full-on word-salad stream-of-consciousness here about graph counting. The following won’t make sense to you because I will not be making any effort to explain what I’m writing or why I am writing it. Sorry. Sucks to be you. This is for me, only.
So I figured out I can store marginals with patterns, and this is a great idea, and I’m stumped as to why I didn’t figure this out years ago. I guess its a process. So one of the processes is counting. How? I can write a filter, I guess, and hook it to an input stream. Maybe I should just do this and see what happens.
But this is irritating because (a) I have to write code, (b) it does not directly tap into LLM ideas. The solution that seems like it would be wanted would be some way of autogenerating code that would do the pipeline counting ... running different variants of it in parallel ... somehow selecting which of these are better, but how? How do we know when one of these auto-gen’ed snippets is better?
Perhaps all this is too low-level. Perhaps there is some phase-transition to general intelligence, and we really do have to build enough basic frameworks before feedback processes can kick in.
So back in the day, I was counting word-pairs and keeping large sparse vectors thereof. But ... here I bonk. I have to consult some references, now. But it’s quarter to ten at night I don’t feel like it. For performance I was using LG to do pair counting. But this won’t go onto GPU’s, cause its not SIMD. Great for multi-core, though.
Now that I “fixed” marginals, I can maybe redo a big multi-core LG counter. But this takes me back to force-feeding the machine, when I wanted to have it do the exploratory thing. So does that mean I have to hand-code more of the exploratory pipe?
The meta issue is everyone is screaming LLM and GPU, which I ignore at my own peril, and it seems to be quite perilous, indeed. So I have to ... go there. Even though gut intuition says its a big honking waste of time. Maybe my gut intuition is wrong. Certainly, ten thousand engineers say I’m wrong, and a million hangers-on are even more sure I’m wrong. So do I buckle under peer pressure, and buck up and take it like a man? Or do I go full-on non-conformist, just like always? Fuck it. Let me consult that reference.
Done. An hour later, and ... foo. Waste of time. Where was I?
I need some system for wandering through a file system, opening and reading files. I need a tokenizer, a word-pair counter. I need a way of storing counts. Where do I store counts? Again, I can use an engineered solution. Don’t want that. Lets g back to file system crawling. Step one is “remember where I’ve been”. So, log the URL and it seems OK to engineer that. Next, what is the actual memory? Increment a count on each URL? At some “well-known location”? That’s engineered, again, but maybe that’s OK. The file corruption project has the idea of witnesses, so that each sensorial visit is tagged with a witness link, associating the URL to a time-stamp. The sensorial device generated a variety of data, those are URL-asscited tags, as well, dictated by the sensorial system. So the sense says, basically: let me do things, and I will fill up the atomspace with observations that include URL’s, witnesses, file sizes, file types, and whatever else that sensor conventionally “wants” to do. For now, I guess, the sensor is engineered, and I guess that’s OK, because the activities are now defined by the sensor itself, as opposed to the user of the sensor.
And this is perhaps the key distinction: the sensor acts as an agent, “doing stuff”, and leaving a trail of shit aka fermentation products aka “output” in the atomspace. It behaves autonomously, and not under supervision. A different agent, also acting autonomously, can be a counting agent: it crawls over the ferment, and counts. A third agent can then act as an inhibitory control, telling the first sensory agent: “now you’ve visited this place before, don’t do it again”. (or maybe do do it again, because this time, we ratchet to some other higher protocol level.)
So the architecture now has three pieces: a crawler, that crawls and generates witness stamps. It also publishes the format of what it is going to generate, as both a pattern and a variable declaration. So that others can look at it and see “OK, that’s the format of what you are generating” Then there is a generic counter agent, which ... takes any pattern whatsoever, as input, and increments on it, maintaining a count. Where? Anywhere. The counter is also an agent, it can store wherever it wants, and it will publish that location if anyone is interested. It’s part of the description. The third part is supervisory, and tries to give suggestions to the crawler to do this or that but not something else. Two things are not clear: what the control interface to the crawler is, and how the supervisor makes decisions.
So the sensor can dump data into the atomspace, but ... the counter needs to know what “fresh data” is. One idea was to have dataflow pipelines, so that the output of the sensor is directly coupled to the input of the counter, and that LG style connectors are used to accomplish this connection. But still, the things in that pipeline are atoms, so they clog up the atomspace, and ultimately need a pruning or forgetting agent to go with.
Is there a viable alternative to direct flow? Search is inefficient, esp since we need to “search for what’s new”. Well, if we know that data is time-stamp-tagged, then the search is for everything newer than the timestamp. which is ugly if 99% of the atomspace pattern contents is older than the timestamp. There’s also the old idea of dropping off new content at an anchor point. That anchor point would then obviously be the sensor itself, and a part of the sensor description would then be “here are my anchor points”. Located at the anchors would be QueueValues or the UnisetVallues, so that part is good to go. So ... there is no alternative to flow, but maybe its not so bad, because things can flow into queues, even if there’s no consumer.
Well, that works only till we run out of RAM. So maybe there needs to be .. oh fuck, why didn’t I think of this earlier: an Atom dequeue malloc. Today, in the atomspace, you can malloc an atom, and add it to atomspace, without any penalty. But perhaps there needs to be a control system: not more than N atoms allowed inside. Even by type: no more than N atoms of type X allowed inside. Every atom insert then checks to see if its allowed, or not. This does make atom insertion more costly.
So maybe this becomes a new “motor” system, layersed on top of the atomspace, that presents the AtomSpace interfaces, but performs validity checking before accepting inserts. Which is cool, except the atomspace API is C++ and not atomese.
But QueueValue also does not have an Atomese interface: things get stuffed into it via c++. There’s no “EnqueueValueLink”. There’s a SetValueLink that places a value at a key. There’s an atomic increment. Perhaps teh atomic increment can be reporposed for non-numeric things to mean “atomic enqueue” Wow. OK, so that’s a great idea. See? free associating into this diary does work! Again! More than a few times, even if its word salad to you. This is very interesting because in college, I could not type this fast and long-hand-writing didn’t work, but maybe that is what the Enlightenment was all about 300 years ago: write long diaries to yourself chewing over ideas, forcing them to be just concrete enough to work, that you can force it to happen, which is more difficult to do, whe not writing. I get ideas when I walk around, but they are difficult to keep coherent, because its like juggling: I have to keep it all live, as I walk around, juggle and not drop the ball, but here, where a I free associate into text, I can drop the ball, and its harmless and so fucking what. Its in words. The words will be there later, so tomorrow morning, if I forget what I thought about today, I just look at this text, and go “oh yeah, that’s what I was thinking”, which is something that I cannot do if I got my bright idea while walking around, and forgot it by the next morning. SO typing is, at a minimum, a personal memory prosthesis. I mean, it clearly is culturally, but writing to myself in private somehow works better than thinking to myself, without the writing. And this is duh, yeah, that’s why people keep diaires, and I’m rediscovering the obvious, but sometimes the obvious is so fucking astounding. The obvious should not be taken for granted. The obvious is sometimes asounding and gobsmacking. But I digress Lets get back on track.
So I have a QueueValue, but no way to enqueue things there, except by C++ interfaces. So I guess I need an ’InsertIntoLink’ that will insert. The QueueValue is also unbounded in length. So I kind of need to turn it into an agent, which says “I have a built in length, and here is what my control mechanism is for adjusting that length.”
Next, I have the UniSetValue which is a deduplicating set, which means it is almost like an AtomSpace but not quite ... I mean, it is implemented on top of the cogutils concurrent set, and its NOT implemented on top of the atomspace, but perhaps it could or should be?
So again we deal with historical design snafus. Every atom contains a point that says “here is the atomspace I belong to”. Is that pointer really needed? For implicit execution, yes, its nice. Neither UniSet nor Queue need to force an atom into belonging. Nether has the additional methods that the AtomSpace does for finding-by-type and so on, but maybe we should put the atomspace on a slimming diet and get rid of some of this crap that was always ugly? Wow. That’s actually another great idea, I guess. Remove old and unused atomspace API crap.
Why does an atom need to know what atomspace it belongs to? Why can’t the atomspace be more like the uniset?
Another piece of atomspace crap is the get-atoms-by-type API, which feels like a crutch. But that crutch is used by the query engine. So AtomSpace is actually a collection of Unisets, and it was custom-coded that way in the distant past.
Unlike the uniset, the atomspace does not have a blocking remove and block if empty” and maybe it should? Wow. This is a reasonable long-term evolutionary design to push for.
So we need an insert-into-link, and a dequeue-from-link. And we need motor controls to allow a max-size to be set.
So this means create a new class of values: agent-values, which have sensori-motor interfaces on them, very simple ones, that say “i can be inserted into, I can be removed from, and I have a size. The atomspace is complex, because it also gets an “I can be dequed be type.”
I need an insert-into-link, a dequeue-from-link, a get-contents-of-without-dequeing link (make-a-copy-link), and a get-verything-and-empty-out-link. Wow. OK.
Well, one step at a time. My mind boggles.
I’ve been here before. I’ve had any number of great brainstorms, in the decade past, and I have to acknowledge that many of the ideas were not quite right in their first form, and had to be reworked two or three or four times. So this queue/dqueue might not quite work out, but agentizing the infrastructure seems like a good idea. It would certanily make the whole sensorimotor apparatus much easier to implement. Less hacking, more directness. Immediate, concrete. Huh.
It is now exactly midnight. I’m signing off.
5 February 2025
OK. So I wrote a bunch of stuff above, and I sat down to do it, but then got interrupted, and then some time elapsed, and now I have no clue what the plan is, so I have to recreate it from scratch. Or I could read what I wrote above. ....
Re-reading above ... there was concern about over-flowing a queue, but this seems immaterial at the moment.
Then I talk about creating atomese that can place things on a queue, and dequeue. This is more interesting.
Related to this is that the atomspace is a big slosh-tank. Kind of like UniSetValue but with extra stuff. It feels like there’s some unresolved tension here, but solving this right now also seems lower priority. Well, lets at least spell out what this is. First, every atom as one pointer into the atomspace, which means any given atom can belong to only one atomspace, ever.By contrast, one atom can be placed into many UniSetValues. And I guess this is OK. Basically, it says that the atom has no incoming pointer to the uniset.
Should the atomspace be changed to be nothing more than a mutable link? That is, remove the backpointer from the atom, and instead use the incoming-set mechanism to indicate which atomspaces an atom belongs to. This pointer does not seem to participate in any high-performance corridors, so this change could be made. But this is some nice-to-have theoretical cleanup and cleanliness and design perfection that no one is going to notice or care about. It changes very very little in how any ordinary user would perceive the system. So I’ll queue this as a nice to have to-do list for the future. And mostly-ish ignore it for now.
The original task was to compute vector similarity, with the vectors arbitrarily defined, and coming from anywhere. i.e. from a search pattern. So step one is to define a similarity-computing agent. This agent needs to indicate that it can take two columns of data. So it defines two input connectors. For hamming distance, this is enough, because just set overlap is counted. For cosine similarity, the connectors need to indicate that they also need float point data, and the linker needs to link that up.
So now we come to the linker. Hold that thought. I am going to prototype something, right now. The linker is the interesting part, but I want to get the prototype in place, first.
5 February 2025 Ongoing
... or not. I’m wildly confused. Let’s consider Hamming distance. There are multiple issues biting me. There is an existing SizeOfLink that correctly returns set sizes. There is no SetIntersectionLink to compute set intersections. Should there be? Normally, this would be accomplished with a pattern query. Or is it ... how?
I’ve got R(x,y) a binary relation. Fixing a, R(a,y) is a vector, and fixing b, R(x,b) is a vector. Now want to find the set intersection: all y in R(a,y) such that they appear in R(y,b). So define an equality relation E(x,y) and compute the pattern R(a,y) and E(x,y) and R(x,b) and the diagonal here is the intersection. OK, that will work.
6 February 2025 Morning
Dear diary: here we go! We’re going to have to settle into this; I’ve only had a little over seven hours of sleep today, and my head is still groggy; I normally have 9.5 hours of sleep, and wake ready to go. But my sleep hygiene is mediocre: sometimes, I allow myself to think things (force myself to think things?) that keep me awake, tossing and turning in bed. Were I to rise, I’d be fuzzy-headed and useless, so laying awake in bed seems a better option. But it is not always pleasant, either, as some thoughts turn anxious.
This is all, I presume, completely commonplace in humans, there must be a million attestations of this. But this one is mine.
But I’ve put off the main topic that I wish to write about, and now is the time for it. I’m still groggy headed, fuzzy, a bit slow. Drinking coffee ... will it kick in? How long before that “normal feeling” comes back?
So what was keeping me awake was that there are severe interpretational difficulties of the idea of the prison of the here-and-now, with the idea of Minkowski space. So let me rewind back to the beginning. Subjectively, we appear to be trapped in the here-and-now, unable to alter the past, unable to remember the future. Objective evidence that this is a physical truth, and not just a subjective truth, is that evolution has given animals brains, wildly complex and sophisticated devices, designed to tackle the problem of prognosticating the future. For example: there is a tiger in front of me, and he might eat me, so I better use my free will, and get the fuck out of here. The tiger has a brain, too: “oh no, my prey is running away! If I don’t go catch it, I’ll starve!” If everything was pre-determined, as is occasionally argued by some certain small class of physics-philosophers, then nature would not have evolved brains. If all was predetermined, I would not need a brain to run away, and the tiger would not need a brain to catch me. Wed both reduce caloric demand associated with thinking, and do some other organismic thing, instead. So clearly, the here-and-now is a physical truth.
In the weeks, months and years earlier in this diary, I’ve attempted to articulate a picture of the here-and-now as a frothy quantum turbulent front of not-yet-settled, not-yet quantum-collapsed boundary between past and future. It has some finite width, and more properly, not a single width, but a multi-scale superposition of soon-becominig-past and unresolved future possibilities. Turbulent: turbulence happens at all scales. High-dimensional chaos. Very high-dimensional chaos, if we imagine space to be a planck-scale grid, with each grid-point holding some Boltzmann distribution of matter. Chaotic, ergodic from somewhere around that scale, up to some microscopic, millisecond scale in conventional experienced reality (longer time scales for quantum experiments conducted in a lab, in a vacuum, etc.)
And this all sounds entirely plausible, to me, at least, but for one little thing: Minkowski space. Time dilation happens. When I was a grad student in 1988, I took a mandatory lab course, and measured the lifetime of a relativistic muon. We had some mini-accelerator, and you could dial up the speed, and yes, it took longer to decay. Graph this on a chart, and the intercept with the y-axis, where the muon is not moving at all, gives you the muon lifetime in the lab frame. We have almost one hundred years of relativistic quantum experience behind us. Its true, it holds.
It holds at the non-relativistic scales, too: put an atomic clock on an airplane, fly around, the passenger arrives some microseconds younger. And this is the part where the vision of here-and-now as a frothy time-front collides with Minkowski space. It is what kept me awake, and didn’t let me fall asleep. I originally wanted to think about what happens when here-and-now falls through an event horizon, but no, we already have conceptual difficulties in Minkowski space.
The difficulty is this. The airplane passenger does not arrive a few milliseconds in the future from me, at the destination. He arrives here, now. You cannot hop on an airplane or a very fast rocket, use some binoculars to peer out the window, and get a glimpse of the future: “Hey Charlie, I’m in the future now, and I see this tiger jumping out of the grass and eating you; you better run”. Well, of course not: the photons from the tiger arrive at light-speed: the observer with the telescope is necessarily viewing past events. Whose past? The observers past. The observed events were, once upon a time, the present, for the observed.
I’m getting off track, this is all obvious. But the paradox remains: the airplane traveller does not arrive in my future, nor do I in his: when he stops moving and comes into my lab frame, our clocks synchronize, and we both experience “here and now”, together, at the same time. So what the fuck happened on the god-damned airplane, then? The airplane passenger was in his own lab frame, and experienced time normally. Specifically, he had an atomic clock, using quantum principles to measure time. Those principles are subject to the various quantum-speed-limit theorems (Mandelstam 1940’s, others, 1990’s and 2010’s, I wrote (re-wrote) almost all of the Wikipedia article on quantum speed limits. I understand this shit. We’re talking about time, here.) So we’ve got this clock on an airplane, and it ... goes slower. In a very literal sense, because when the airplane lands, the present “here and now” in which we are trapped allows the passenger and I together agree that his clock ran slower. But, for him, everything ran slower: not just his clock, but everything: his body, the plane itself. His experiental reality of “here and now” moved slower as well, so that when he rejoins me in my lab frame, his “here and now” is exactly equal to mine. Not just approximately, not just off by a few microseconds, but exactly.
Of course, here and now is at least a few microseconds thick, so there’s room for some slop. Portions of “here and now” are ... hours thick. When I observe Jupiter, naked eye or telescope, I see “here and now” is it is (was?) on Jupiter, but that is 43 minutes away, plus or minus nine minutes, depending on the relative positions of Earth and Jupiter. So that is an entanglement: a quantum entanglement, because we are talking about photons, this is not on the nanosecond time-scale, but on the hour timescale. And it really is “here and now”, because I cold shout out “watch out, Jupiter! There is a tiger in the grass about to jump you! Oh, wait, no, that’s just comet Shoemaker-Levy. Why didn’t you get out of the way? Oh, you don’t have a brain. that’s right. That, and no way to propel yourself. Jupiter, you literally have an IQ of zero.”
So the here and now of simultaneity extends up and down the light cone, out to the age of the universe. This is, again, well-known and obvious, and the geometry of null geodesics is carefully described in umpteen textbooks. And there are dozens more “of courses”. So the problem is perhaps revealed, a tad: “here and now” is not a sharp line dividing future and past, but a boundary having thickness, a few nanoseconds, when I talk about my feet, an hour, when I talk about Jupiter.
I dunno. This leaves me still not entirely satisfied. I can’t put my finger on it. I’m on my third cup of coffee, its now an hour after I started writing this essay, my head is still fuzzy and groggy, and all I know is that I am not satisfied with some aspect of this conception of here-and-now. I suspect that, even if I had slept a few hours longer, I would still be unhappy about it. And maybe no closer to a solution?
OK, so here’s part of the problem. When I talk about light, then obviously ... well, lightcone. But the problem was with the perception of time by the traveller. Basically, the acknowledgement of “here and now” seems to cry out for some kind of ether, through which here-and-now passes, like a wave. This is NOT the same ether is that of the light wave (which we know doesn’t exist, Michelson-Morely, yadda yadda.) So that ether doesn’t exist, but the here-and-now seems to want its own kind of ether, through which my lab frame propagates with unit proper speed. And that’s the conundrum: For massive matter, proper time moves with unit speed. Through what does time move? Well, now we can maybe? Finally? Perhaps step back and talk about geometry? Does that solve any problems?
So the geometrical viewpoint is this: one says, “a hah, spacetime is curved, and see here, geodesics are straight lines...” Which is all fine and dandy, but you get into trouble, if you slap a coordinate grid on spacetime, and attempt to say “here and now is right here and now at coordinate (x,t) in that coordinate system, ooh, wait, it moved, why here, now its over here, shifted by proper time T, because you must understand, proper time advances at unit speed in the lab frame. So, fuck you: show me where “here and now” is, in your fucking coordinate system, and why it lines up for the guy on the airplane, when his airplane lands, and his clocks resync with mine? Where is “here and now” in flat-fucking Minkowski space, you puscillanimous puppy? Yeesh.
We start together, I say here and wait an hour. You fly around in an airplane for exactly one hour and ... what, you arrive a few microseconds in my future? Your clock ran slower? That’s your excuse? We are both in here and now, how come we can’t agree about how much time has elapsed?
So this, all these thoughts, this is what was going through my head, as I was sleeping/not sleeping, tossing and turning. And one more interesting thought shot in my head: perhaps, once we figure out how to resolve the here-and-now problem, we might alight on a solution for MOND in the galactic rotation curves. Maybe it is here-and-now-ness that is causing the MOND-like effects. The point is that the moving arms of a galaxy are moving, and so get time-dilated. Some hand-waving about Mach principle: the cosmic microwave background CMB does provide an absolute reference frame. We can crank through this, and see where it goes. Its in chapter 7 or 8 of Ellis–Maartens–Maccullum Relativistic Cosmology, yes, I’ve read that far. I can’t look up the page because I was reading in the browser tab and the browser is down, but its like page 120 or page 150 or something, several chapters into deriving stuff in comoving coordinate frames. Should I take a break, start the browser, and properly download this time?
So anyway, we can do enough geometry to define comoving frames, and split up all generalized FLRW type systems into explicit 3+1 forms, with assorted shear tensors in there, and what not. So there’s an algebraic basis within which one can work. Up to a point ...
See? I’m getting caught in the weeds, again. Yes, of course, one can take the CMB and use it to define a space-like surface, the surface of last scattering. And then one can take this surface, and call it “here and now” and use it as a 3+1 coordinate frame, and then express all geometry with respect to this coordinate frame. As the Ellis etal book makes clear, there’s a lot of terms in those 3+1 algebraic expressions; they’re long, complicated and have unusual shear and rotation terms in them if you are not accustomed to this, yet. Fortunately, those terms vanish when you need them to, so everything is all good. So comoving coordinates do provide a kind-of-ish here-and-now reference frame, for cosmological calculations. And that’s great! But it still doesn’t explain what happened to the clock on the airplane. Why here-and-now clock-skews during the air-travel trip.
Or perhaps it does? Perhaps I should stick the path of the airplane into the comoving coordinate system and get ... get what, precisely? A big fumble of equations, that tell me, what? That there’s Lorentz time dilation? I don’t need a big fumble of equations to do that. I already know there’s time dilation, I just can’t ... put my finger on it.
Maybe the airplane trip is MOND-in-minature? The guy on the airplane flew in a circle... our clocks do not agree, our conception of here and now does agree. Our clocks are quantum devices, quantum is fully relativistic, the clock on the airplane measures time in the airplane frame. Which is no an inertial frame, but the acceleration effects can be ignored. I think. I assume. If I were to be careful, I would calculate the acceleration effects, and say “a hah these are fully ignorable” but I am lazy, and besides, someone else has done this, and if they were not ignorable, then I would know about it because it would be in textbooks. But I don’t know about it, therefore, its ignorable. Interesting chain of deduction, there. Just saying it out loud; of course, people think like this all the time, which is why they get so surprised when they find out they’re wrong. In the present case, though, I’m pretty sure I’m not wrong: the acceleration effects on clock skew for the air-trip are negligible.
The airplane trip is macroscopic; can I gain anything by going microscopic? I dunno. I can put muons in an accelerator, and get relativistic time shifts. Are there any other clocks I can accelerate to relativistic speeds? The problem with quantum is that it doesn’t not “really” experience “here and now”. Maybe the quark-gluon plasma does? I mean, the muon clearly experiences time, But the radioactive decay is exponential, not some sharp cliff. That sort of suggests that the muon is confused about where “here and now” is, and it has a lot of leeway in deciding when to decay. Of course this is a highly heretical description of decay; the point is not to claim that this is how muons actually work, but to claim that “here and now” is very ambiguous at the quantum scale. At the macro scale, we’ve got ergodic, chaotic dynamical systems with billions of degrees of freedom: brains experience here and now. Obviously. It is not clear how much smaller one can get. Bacteria, I suppose: look at what nature has done with white blood cells, killer T-cells: the immune system is hunting down enemies in the blood stream, and this is very much a here-and-now experience for both the killer T-cell, and the hunted bacterium. It’s the same as it was for the tiger in the grass.
How about viruses? We run into problems, and if we’re not careful, talk about panpsychism and integrated information theory. Is “here and now” fundamentally observer-related, much like some of the Schroedingers-cat arguments require brains to observe? Wigner’s friend, and all that?
So this is where we bump into the wall of understanding how quantum interacts with complex many-body systems, the so-called thermodynamic baths and whatnot. The hand-waving is that a quantum measurement collapses upon interaction with a many-body system, but I think I’ve spilled plenty-enough bytes on this topic, earlier in the dirary, with no satisfactory resolution.
I did read about some Japanese(?) researcher who recently took some gas of sodium or cesium or something at 500 degrees Kelvin, and was able to observe thousands of entanglement interactions for the next millisecond. That is, some entagled state is prepared, and then the system is released, and then, for the next thousand atom collisions in this hot case, the entanglement is passed off from one atom to another. It is not erased upon the first collision, it is not erased in the first ten collisions, it takes many, many collisions before it finally thermalizes. So this is interesting: it confirms that ... that ... what? I don’t know, because I read about this on some pop-sci newsite, which, as per usual, garbles whatever the actual physics is occurring. And I didn’t read the paper in the original cause god knows I have enough to do, and enough ADHD to not do it in.
So... is the here-and-now problem somehow synonymous with the quantum-collapse problem? I mean, ts obvious that large systems, the kind of systems that biological evolution works with, experience here-and-now. It’s not obvious that non-conscious, non-living things experience here-and-now. Well, sort of. The riverbanks of a raging river do appear to experience here-and-now. Erosion is real. Erosion is thermodynamically irreversible.
So is here-and-now something to do with thermodynamic irreversibloty? Possibly ... probably. But we still have the Minkowski-space relativistic clock skew issue, and I don’t know how to formulate relativistic microcanonical ensembles. I mean, yes, I can do a relativistic gas: I can look it up in a textbook. I know which textbook too: relativistic gases are standard material for cosmologists. But a relativistic gas is not the same thing as airplane-ride clock skew. The killer T-white blood cells are experiencing Loerentz time dilation along with everything else on that airplane. The thermodynamic irreversibility is proceeding apace as the stewardess mixes a rum and coke. The rum-n-coke gets Lorentz time-dilated, too. How does the atomic clock work? Well, its got some Cesium, and some electronics...
The point here is that the thermodynamic “increase of entropy” is happening at the same speed as the clocks are measuring on the airplane. At least, that is what one is urged to conclude, based on conventional textbook teaching. I mean, Einstein himself tells us that classical mechanics on a speeding train works the same way as it does non a stationary train, and, by extension, so does thermodynamics. As far as I know, no one has done any experiments to confirm that rum-and-coke on an airplane mixes just as rapidly as it does in the airport lounge. But it would be insane to think that thermodynamics worked differently, because you would think that if it did, it would manifest in some obvious fashion. No. We must take as a given that thermodynamics is fully invariant, covarient, whatever word you want to use: thermodynamics feels proper time in the lab frame.
See? So we keep getting fucked, over and over again. A buddy standing next to me gets on an airplane, creates some entropy there, arrives with his entropy which is now a few microseconds younger than my entropy, but were are both in the here and now. And his clock was a quantum clock that collapsed it’s wave functions in a fully covariant relativistic way, because otherwise his clock would ... have worked differently? ??? And there’s no reason to beleive it works differently, and there’s nothing to grab hold of here, that could be formulated into an experiment that might plausibly give results that differ from textbook predictions. The Bell test proved entanglement. I do not have the analog of a Bell-test for here and now.
Hmm. How about interferometers? Can I build some interferometer experiment, where one arm is in “the lab frame”, and the other arm is somehow “Lorentz-contracted”? Ooof. Suppose I could build such a device, what would I learn? The analysis is difficult. Interferometers conventionally use light. I guess I would need a mater interferometer. Say, a neutron interferometer. But we already know that gravity works correctly with neutron interferometers, one does have a gravitational Bohm-Aharonov effect going on there. I have to thank Frank Yang for that: the one class at Stony Brook that he did teach was filled with these non-conventional off-the-wall type topics. He wasn’t working off a textbook. He was working with all the strange and bemusing marvels that tickled the intellect, like having neutron waves that felt gravitation. Phase difference of exp(i(mgh)t) or whatever. How might I create a “here and now” interferometer? Send two bacteria on two different paths?
Again, what is the largest clock I can accelerate to relativistic speeds? I don’t mean some large nucleus with some beta decay mode. Yes, that is clock-like, but its not thermodynamic. .. Stop. I already concluded from the airplane trip that, even if I could get a large, thermodynamic-scale, Avogadro’s-number size clock accelerated to relativistic speeds, it would behave exactly as Lorentz would expect. So where the fuck is here-and-now happening? I’m fucking completely stumped.
6 February 2025 Evening
Twelve hours later. I did something else till I got fried, Started reading Ellis et all again, finished chapter 5 (matter), skimmed chapter 4 (kinematics) again, and came back to here. The bonk I’m having is that here-and-now is not a coordinate (kinematic) problem, its a dynamic problem. There’s no problem whatsoever o laying down a coordinate system on Minkowski space, and of expressing the proper time for any inertial observer whatsoever. We can label however we want, there’s no confusion or ambiguity.
One can do even better: one can sprinkle the space with smart dust: these are inertial radio transmitters, each broadcasting, via radio waves at a given (fixed) frequency), their unique ID number, their proper time (as carried by an onboard clock) and the broadcast is encoded with directional beam data. Thus, you as an observer, can receive this data: from redshifts, you know how fast they are moving. You can double-check this by looking at the timestamp they encoded; this should be 100% identical to the redshift. You can determine transverse motion, because the beam-direction encoding is changing, which is again identical to where you see them. You can determine distance by measuring signal power (brightness). All motion is purely kinematic, all data should be 100% consistent with whatever calculations you make for the trajectories in your chosen coordinate system. For each and every transmitter, you can say with absolute confidence where “here and now” was, and will be (because there is no interaction (other than sending/receiving data), and the dynamics is trivial – just free particle motion.)
In this picture, we get a “timeless” picture of Minkowski space: were know where everything was, and where everything will be, and when it was, and when it wiil be, for you, and for any transmitter.
The problem is to reconcile this timeless vision, with the idea that, for any given transmitter, the future has not yet happened. By the time you receive a signal from them, you know where they were, then, because the always transmit “right now”, by definition. Everything you receive is in your past light cone. You can predict (with perfect accuracy) what you will receive, in the future. The “here and now” clock ticks independently for each and every transmitter: They don’t need to have been synchronized in the past. They do need to agree on frequency; as otherwise, you cant tell who is redshifting or not, although I guess you can track change in received power.
So, when I receive a signal, right now, I know it was sent, “right then”, bu the sender. If a transmitter is coming straight at me, I know it will be “right now” exactly when they pass by, because I will receive the signal, immediately, as they send it, and we will both be sharing that “right now” moment together. This will occur because our worldlines intersect, and when they intersect, it will be “right now” for both, and this will happen at the “same place” for both. It cannot be any other way. This is obvious, when put this way.
In this picture, there is no confusion about where “right now” is, and there is no magic synchronization of “right now” that is needed: it happens where needed, as needed, and it happens independently of the observer. Time marches along for each transmitter, independently of all other transmitters, and there is no need to coordinate about ’where’ ’right now’ is happening. There is no magic coordinator of “right now”. There is no need for one, and there’s no paradox. Right?
If there’s no paradox, then why am I spending hours and hours confused about something? What am I confused about? Why am I confused? I’m not dumb. When I have been confused in the past, it was because I mis-understood something, made some faulty assumption that was not true. Upon fixing the mistake, the confusion evaporates. In the present case, what is the faulty assumption that I am making? What lies at the root cause of my confusion?
7 February 2025
Went to bed at midnight. By 7AM the answer to the above is in my mind. The next question: should I get up now, or go back to sleep?
The basic confusion is between mathematics, physics, postulates and observation. In mathematics, we have the ability to write down pseudo-Riemannian spaces, with metric, in arbitrary m+n dimensions, and everything “just works”. Lots of well-developed tools and techniques. Observationally, we know that we live in a locally flat 3+1 space, and even cosmologically so. There’s a question: why is is it 3+1 instead of some other m+n? But that is not what we’re trying to ask.
So now we have physics, and postulates. We can postulate: in a 3+1 flat Minkowski space, clocks moving along paths behave exactly as the mathematical machinery should predict they do, and we know that the mathematical machinery is self-consistent and complete and paradox-free. We postulate this as the correct answer, because we have oodles of observational experience indicating that this is the correct answer. Once this is accepted as a postulate, then there is no paradox. The physics (perhaps its meta-physics?) is “sure, but what if I don’t postulate that answer? Can I derive it from other principles?”
Or perhaps it is something simpler: a Newtonian rebellion. Conventional experience is so firmly rooted in a Cartesian 3D world with one linear time dimension that the malleability of time is a counterintuitive surprise. I can either throw up my hands and say “yeah, whatever, this is just the way time works” and move on to something else, or I can continue to bang my head on a wall, and ask, “but why does time work like that?”
The difficulty with the second approach are the mathematical tools, again. Our tools work in any m+n dimensions. We can write down any classical field theories in m+n. These theories will have many–body statistical mechanics that is fully compatible and consistent in m+n dimensions. We can even quantize most of these field theories. We can of course do this for n=0 and taking a distinct Newtonian time for the differential eqns and the (measure–preserving) dynamical systems. And this is all consistent. So it would seem that there’s nothing in stat mech or QM that we can look at, employ or use to determine the underlying causal structure of spacetime. Those theories all take causal structure as “input”, they do not generate causal structure as “output”.
The closest that we come to having something that can have causal structure as output is the classical Einstein–Hilbert action. But even that is a cheat: it already assumes 3+1 as the microscopic, local tangent space, and only turns the metric into a dynamical variable, and asks to solve for the metric.
I am not asking to turn 3+1 into a dynamical variable, perhaps because I don’t know how to make integers dynamic. Or perhaps I do? There’s all this fractal Hausdorff–dimension stuff and so maybe, just maybe, one could instead start with some measure-preserving dynamical system with structures having a variety of fractional dimensions, and write down some kind of action for that, and then discover that this action is minimized when most or almost all structures have a 3+1 Hausdorff dimension. Something along those lines.
Is this what I’m looking for? Secretly imagining? Is Terrence McKenna right in saying there’s a little radio receiver in my mind, listening to whispers from the universe as to what the physics of it is? These intuitive, creative insights really do seem to come from somewhere else. Well, of course, they do: they come from the non-verbal subconscious mind, and the verbal mind gets surprised: where the fuck did that come from? It must be God speaking to me, or the Universe, or little magic molecules that live in mushrooms, in the case of Terrence McKenna. Of course, all of this is wrong: the creative insights are just coming from another part of your brain that is not your verbal centers. And your verbal centers are sufficiently detached that they get surprised.
So this is a good time to relate another strange thing that happened. As I slept and dreamt last night, in one of my dreams, I was reading a software review. It was comparing a number of different software systems, including the AtomSpace. The review was making some fairly deep theoretical insights, and the conscious I, the lucid observer, struggled to determine if these statements were true. That is, the dream had these words, these sentences. The lucid dreamer was trying to check if the words were saying something true. It was challenging. For a while, me, the lucid dreamer, kept trying to put the dream on slow–mo, to pause the dream, so I would have more time to determine the accuracy of the statements therein. But as you may know, pausing a dream is hard. One can, sort–of–ish do this, slow it down, prevent the dream narrative from advancing so rapidly, but this is not easy. So after a while, I have to give up on this, and so I am hearing this verbal stream making complex technical assertions, and the lucid me is doing this “sounds about right” but I can’t keep up. So its like a college class or a lecture where the speaker is going a bit faster than your comprehension, so you can’t quite keep up. And so the lucid me is marvelling a bit: how the fuck is the dreaming me coming up with these words, that seem to be expressing complex ideas that are more or less technically correct? I mean, me, I, consciously–aware I, am here, experiencing the dream, and in that dream, there is some text that I am reading/hearing, and that text is from not-me, its from the background texture of the dream. How did it get so technically accurate? It’s quite the surprise. In conscious, waking life, it is ’me’, the self–aware me, that is always with me, indivorceable, and it is that me that does all the thinking. So it is a surprise when there is something ’other than me’ that is getting things right. So, I know I’m dreaming, so I know this is all in my own skull, so the surprise is that there’s some part of my brain, that is not part of lucid-me, that is capable of generating accurate verbal synopsis of difficult abstract concepts. Wow! Lucid me was surprised! Lucid me is used to it’s kingly authority as the fount of all consequential thought and action. There’s a part of my brain, detached from self-aware me, that appears to be capable of verbalizing complex ideas. Very interesting.
Now that I’m awake, I can rationalize, and say, perhaps this should not be a surprise. Some of my lucid dreams have these incredible photorealistic landscapes (I love those dreams!) where any direction I look out on, I see things is sharp, clear focused detail: fields and forests and clouds, in impeccable, rich colorful detail. And lucid me never stops to wonder “hey wait, where did these fantastic images come from?” Maybe because fully–awake me is already quite distantly removed from my imaging system. Certainly, my direct visual system is entirely out of conscious control. I cannot will myself into seeing thing that are not there. And if I close my eyes, and try to imagine a landscape, I can do so only poorly, getting only a vague image (that psych test, one to five, of visualizing an apple, when someone says apple. Hmm. Wait. OK, so that’s false, I am having no problem at all visualizing a clear precise, visually detailed apple. More accurately, I am having a clear, detailed precise vision of the psych-test image, and of the twitter post it appears on. And I can do this without closing my eyes: I see the twitter screen in great visual detail. I could draw it, pen and paper. Well, of course, that twitter thread was stupid. Any and every fine–arts student has the ability to snapshot and hold a visual image in their head, because this is a basic talent you must posses, if you are going to move paintbrush on canvas. So there is conscious control over imaginative imagery. It’s just that the imagery is not a part of verbal me, it is outside of verbal, narrative me. It is clearly “in my head”, where I can access it. But it is not I. The image does not proclaim, “I am you! I’m in charge here! I am king and rule over this entire mental domain!” No, the mental image just sits there passively, presenting itself to the king of conscious awareness. The verbal centers are much closer to the king; like the court jester, constantly whispering into the king’s conscious awareness. The closest advisor. Of course, I have to sometimes tell mister verbalize to shut up and go away, because symbolic abstract thought is not verbal. But clearly, as I write these words right now, verbality is primal. Perhaps not in charge, verbality is being used as a tool by conscious me to express the things I, err, uhh, feel like expressing right now. So, when I think abstractly, I do NOT do it in words. and if I was a fine artist, a painter sculptor, and spent many hours a day, many days a year painting and drawing and sculpting, then perhaps visual image abilities would have a primacy stronger and more powerful than verbal. But I am not .. drawing an painting hours a day. I am ... writing hours a day. I am doing abstract math, hours a day. I am writing abstract software, hours a day. And I am getting physical exercise, hours a day. So these things are primal.
I also wanted to mention tulpas, at this point. There is a central, self–aware me, and the above paragraphs make it clear that I have all these various talents and abilities that are not self-aware. They are inside my brain, they live next to my conscious experience, but they are not conscious, self-aware in and of themselves. The mental image of clouds drifting across a sun-speckled sky is not proclaiming self-awareness. Only I do that. And so, in this sense, I am compartmentalized: self-aware me can pass out, fall asleep, without damaging the visual centers, the athletic centers, the verbal centers. Those centers function, function next to me, a part of me, but they are not self-aware of me, the way that I am. Very curious.
Why do I write this stuff? This is surely spelled out in great detail in a zillion psychology texts. And before that, perhaps great authors of fiction have already presented such analysis in some long novel I have not read. I guess I could say “these are my thoughts. There are many others like them, but these are mine.”
Well, I think I’ve exhausted the psychological angle. Back to physics, maybe? Or am I exhausted?
Where were we? Frothy here-and-now. The tools I have available to me are these: the conventional tools of differential eqns, which encourage analysis in terms of points x which move about. Then there’s pointless topology: frames and locales, which show you how to do topology without points. Somewhere I have a PDF called “Topological Field Theory” I think its a book, or maybe just a very long paper. I have not read it yet. Maybe it’s time I did. The idea here is that measure theory and ergodic theory is a tool that allows working with things that are not points. So I know how to define a measure–preserving dynamical system; I wrote almost all of the Wikipedia article on that topic. What I do not know is how to endow a measure–preserving dynamical system with the geometry of a manifold.
And that is a very good point. I’m deeply conversant with these two quite different mathematical languages. But oddly, I do not understand even the smallest thing about how to hook them together! I do not know how to take some dynamical system, and say “le voila! here is how one constructs the tangent space for this system.” If there’s some symplectic structure, it was always there, from the beginning, built into the dynamics. I never start with dynamics, and then later discover what it’s symplectic structure is. Hmm.
I cannot even think of the most basic example of this. Say, some process taking place on some lattice, and I deduce some geometric structure from it. I guess there’s something that comes close: AdS-CFT where you start “here” and fall out “there”. But that’s already quite .... I mean, CFT is already geometrical, to start with, so finding something else geometrical (like AdS) is cool, but not the topic. Can I start with something non-geometrical, but with something that is dynamical, and then find that this dynamical system has a geometry? The holy grail would be to find that the geometry is 3+1.
I dunno. I’ve wasted enough time, here. I think I’m done for now. I should recap, before closing shop. There is a frothy here-and-now that advances as a boundary between past and future. Observationally, this boundary moves in a fashion that the past has (more or less) the geometric structure of a metric manifold, the pseudo–Riemannian manifold of GR spacetime, and the fields upon it. The mathematical tools I currently have access to do not explain why its 3+1, why it stays 3+1, why its metric, why its flat, and why its Minkowski. These are observational facts, not theoretical deductions. Time in special relativity is quite counter–intuitive. In my mind, I can imagine a frothy here–and–now wavefront, but my imagination wants it to be Cartesian, Newtonian. I can now accede that, sure, this frothy front can be made to froth along in Minkowski space just fine. The froth travels with speed exactly one – the proper time in any reference frame measures the speed of the froth in that frame, and all special–relativistic, Lorentz-contract motions for this froth front are fully consistent. We are forced to concede that “time is weird”, and to live with that. The only way to make time not weird is to insist “time is not weird, you silly goose, you just don’t understand special relativity” but that is a very thuggish statement. Right up there with “give me your wallet.” Insisting is not a very good way of doing physics. But, for now, there do not seem to be any other avenues. Time is proper time, sorry, Charlie, deal with it. Your froth–front is special–relativistic, and more: its general–relativistic. You have both tools and computer codes that do this: you can do supernova on supercomputer simulations, and get all the statistical mechanics right. It all works. Shut up and calculate. For my case, its “calculate what?”
So I’ve resolved some dazed–and–confused paradox by sort of saying “there’s no paradox”, and the correct thing to do is to set it aside for some other day. We’re done here, for now.
7 February 2025 Evening
OK, its now 12 hours later. I did some “real work” today.
I’m tired. I should probably not be doing this. I should probably be reading my book...
8 February 2025 Morning
While sleeping, I realized that cosmic inflation ... well of course it flattens the universe, but it also synchronizes “now” across the entire horizon. The entire visible universe has the same “now”, to a flatness at the same scale as provided by inflation (so, much much flatter than CMB). In particular, the above resolved paradox implies that “now” is not distorted by (dark) matter, because “now” is always happening in proper time. Intervening matter might make clocks run slower for some observers, compared to others, but there is no shear; when two observers rejoin, their “now” will agree. That is, “now” is synchronized for all comoving coordinates, and even more strongly: it is synchronized on the spacelike surface at which inflation ends.
This raises several conceptual issues. First: is “now” a property of spacetime itself, or does it require additional fields? Does it require few-particle quantum? Does it require statistical many-body quantum? Is it a property of the quantum vacuum? Earlier thoughts on the thickness of “now” implies that it is necessarily a problem of revising causal (quantum) interactions between different parts of spacetime. Thus, frothy-now is, at this level, something that happens in the presence of normal matter. I have not considered if froth is a property of the quantum vacuum. I suppose it should be, but given that I have almost nothing to grasp hold of, who knows.
A second question is “what would happen if two observers, experiencing different ’now’, were to meet?” This is more or less unanswerable, since cosmic inflation guarantees that everything in the visible universe has the same ’now’. I cannot run that experiment.
The paradox still bugs the shit out of me. Lets see if we can make forward progress. So, at the end of inflation, we have a space-like surface that is flat by virtue of inflation. It is unique, in the sense that one could pick other space-like surfaces, but those would have points that are in the future from the end of inflation. That is, there is only one space-like surface, on which the proper-time distance to the end of inflation is zero.
This unique surface defines a Newtonian frame. Every point on that surface has exactly one unique perpendicular time-like vector. By axiom, by assumption, we say that ’now’ starts synchronized on this surface. Perhaps it has some finite thickness already, and so we must talk about the mean, average ’now’ on this surface. But at the moment, nothing is lost by assuming it is precisely sharp and free of shear and vorticity.
This gives us a unique, and very Newtonian definition of ’now’ for the future of the universe. Starting at that surface, integrate the perpendicular proper-time vectors. This gives a single unique vector field flow, for all points in the spacetime of the universe. By hypothesis, the location of ’now’ is the slice (section) at fixed proper time since the end of inflation. This slice is a surface, since, by hypothesis, there is no vorticity in the initial conditions.
This is very odd to me. It appears to be a way of defining a unique quasi-Newtonian coordinate system up the entire universe. My book on relativistic cosmology almost says this, but not quite. In chapter 4, it sets up the kinematics of comoving coordinates. It says “pick a spacelike surface” but it doesn’t say how. It makes the vague implication that this is in the early universe. Since the chapter is on kinematics, of course, it should not say how: kinematics is about developing tools. It then allows you to pick observers on that surface. The observers that you are allowed to pick do not need to be moving orthogonal to that surface. So, if you follow the flow lines of those observers, you will find, in general, some shear and some vorticity. This allows a purely kinematical derivation of the generalized Hubble relation, on page 81. And that is fine and well. I’m not adding some minimal dynamics: pick the spacelike surface to be the one at the end of inflation, *and also* pick observers orthogonal to that surface. Thus, by definition, both shear and vorticity are set to zero, for “now”.
And so we kick things off. Let the universe evolve. Allow particles of matter, subject to forces and pressures, do their thing. Most of these will not be moving on geodesics, because they are subject to forces and pressures: i.e. not dust. Pick two observers, carrying their proper-time locks with them. Allow them to be buffeted by forces and pressures. Assume that they meet one-another at some future space-time point. At that point their clocks will have different readings: each will have experienced a different rate of flow of time. However, when they meet, the ’now’ of their meeting has to be identical.
I know this, because that experiment can be performed: my buddy flies around in an airplane with his clock, and he arrives back home a few microseconds younger, but his experience of “now” is the same as my experience of “now”, and is not off by a few microseconds. When the tiger jumps out of the grass to eat us, he does not have a few microseconds advantage at predicting the tiger-jump.
Well, let’s look at this more carefully. He and I both predict the tiger-jump based on sight and sound. Lets stick to sight, i.e. photons, i.e. the light-cone. he and I are getting the same info at the same time about the tiger, because both of us are equally distant from the tiger, and neither of us are moving with respect to one-another, and thus do not have some advantage from the simultanaity ordering of space-like separated events. We both get the same information about the tiger at the same time, irrespective of earlier changes to our clocks. Thus, we necessarily experience the same ’now’.
This paradox is stubborn. So imagine a third observer. They start out at time t=0 at the surface of the end of inflation. The are orthogonal to that surface, and then they ignore all forces and pressures, so as to move on a geodesic from that point onwards. Lets assume that matter is uniformly dispersed, so that there is no lumpiness that would make gravitation bend up the spacetime: i.e. that we can ignore the effects of gravitation on this observer, so that his geodesic is effectively a flat-Minkowski-space geodesic. This third observer arrives at the point where my buddy and I are having a little problem with the tiger, and what does he see? Why exactly what we see: All three of us are equi-distant from the tiger, all three of us are stationary with respect to one-another. All three of us are effectively at the same point in space, moving together, and all three of use get to experience the future based on the sommon arrival of the same signals from the tiger. All three of use experience the same “now”. This is completely independent of any Lorentz contractions that may have been experienced in the past.
So it seems that “now” always travels with the observer, and that “now” always moves with unit speed of proper time, so that “now” is always measured by the clock that the observer carries. But when different observers arrive at the same place, their “nows” coincide, even though their clocks do not. That is the paradox. That is, “now” is always measured by clocks. But also, now is always equal, an equality relation, for observers at the same point on the spacetime manifold. That is, every point on the spacetime manifold has one and only one “now”, unique for that point. All observers arriving at that point get the same “now”, even though they have experiences a different history of spacetime paths.
Formulated this way, “now” is a kind of equivalence relation between paths. So this is homotopy “upside-down”. We start by saying there are many (time-like) paths, but when those paths intersect at a point, those paths necessarily all have the same “now” at that point. This defines an equality relation for those paths. All equality relations induce a quotient topology, In this case, we take the Cartesian product of all paths, modulo equality when those paths intersect.
Of course, this is quasi-incoherent, because, by convention, to define a path, we have to first define an underlying manifold on which the path is taking place. At least, that has always been my understanding of books on algebraic topology. Absolutely none of them say “imagine a bunch of paths, now imagine the paths intersect, now imagine the points at which they intersect form a manifold”. Even in the intermediate parts of the book, where snake lemmas are being presented, I don’t think you can go back and say “see, earlier in this snake, to the left of this snake, there’s not yet a manifold of points, there is just a manifold of paths”. I dunno. Maybe you can? But its always about exact and closed operators, and they have to be exactly and closed on .. something ... and that “something” has to be a space on which paths have been defined. Right? Jeez, I would have to re-read all of these books, and rethink this, fro scratch, to see if somehow, underlying manifolds can be discarded at each step, and higher spaces be built up as quotients of collections of paths with equivalence relations defining what the same point is.
I wonder if some professor would have explain this, if I’d learned this in a class, instead of a book. But the books did not breath a sigh of this. I might have been a sloppy reader, but I swear, none of them say this. None of them say “start with a collection of paths and *define* a collection of points as an equivalence relation on the paths”. Why don’t they do this? Because they would need to somehow define what a “path” is, without making reference to some underlying manifold. And they would need to define an equivalence relation, of being at the same place/point, without reference to the underlying manifold. And, just right now, it seems a bit incoherent to try to do this. Its not clear how it could be possible to do this. Hold that thought. I’m going to git commit right now.
Fuck, I was going to do something else today, I was going to be writing this dirary entry about atomese/sheaf sensorimotor difficulties and issues, and instead I am writing this. Perhaps in some strange way, these two are the same thing.
Jeez Louise, my thoughts keep getting farther and farther out there. My apologies to you, dear reader, who does not exist. Stewing in this craziness, is... fun. It feels like I’m really doing something, accomplsihing something in this muddle of confused thoughts.
OK, so here’s the deal. In my conception of algebraic, computer-scientific parsing, I have these jigsaw pieces. Such as those in Link Grammar. I did not invent these; they have a long storied existence in math and appear and reappear in varied guises in varied contexts.
So now, lets take these as a given. This jigsaw pieces exist “fundamentally” outside of any manifold or structure or spatial setting. They are not objects in any conventional space. I can have collections of them, so I can shove them into a set, or talk about sets of jigsaws.
The connectors on each jigsaw are potentialities. They are connections that could be made, but have not been made, yet.
The brain-storm here is both deep and shallow, as brainstorms are: I can construct a causal spacetime out of jigsaws. Now that I think about it, I imagine that some clever professor, maybe Smolin or someone, has already done this. And maybe even a few decades ago, or more. But still, whatever, I am not going to go on a literature search, until I can first make this idea more precise. Do it in stages.
At the first stage, we have a collection of jigsaws. A set. They have two multi-connectors: one past-pointing, and one future pointing. A link-grammar multi-connector is just a connector that can have zero or more connections, there is no constraint on the number of connections that can be made. For the current scenario, an uncountable infinity of connections must be allowed. This is because any given point in spacetime may have an uncountable number of connections into the past causal cone.
Well, I guess I should have said this up front: these jigsaws are going to be the points of space-time. That is, the starting point is a collection of points, but no topology has yet been defined. The goal is to eventually define a topology. By the word “topology”, I am now imaging the conventional definition, as given in conventional textbooks on general topology. The difference is that I am not starting with structureless points, and arranging them into
,
,
separation axioms. Instead, I am given each point a collection of connectors, and the potentiality of connecting those connectors will result in the separation axioms (so
here is Hausdorff, as per convention). I am very tempted to just drop everything right now, go crack open a textbook on topology, and start writing down *exactly* how separation axioms can be converted into connectors! This would be a fucking excellent homework problem! I guess it has to be done! This would be the goddamned first real, actual activity: everything I’ve written in this diary so far has been punching at smoke.
Cool! Drop everything, and do it! Strike while the iron is hot!
Slow your roll, there, bubba.
Lets assume that the separation axioms can be reformulated into connectors. Somewhere in those texts, it becomes clear that metric spaces and normal spaces and I forget what else they are called, are all the same thing: they are spaces with nice properties. The metric spaces in conventional texts on general topology all use positive–definite metrics. I don not recall ever reading any textbook on general topology that had any pseudo–Riemannian notions in it, but it is probably safe to assume that such textbooks exist. They will be obscure, because this does not enlighten the conventional student of mathematics, for whom pseudo–Riemannian anything is far from the mainstream. Whatever, I wander off track.
So I want to define jigsaws with two multi–connectors: one future–pointing and one past–pointing. Now, this is where it gets interesting. I am fairly sure that I do not need space–like connectors. I think, I imagine, the hypothesis that Cartesian space will magically appear, after stitching together the past and future connectors into a cloth, into a rhizome. The definition of spatial distance will be built out of a definition of proper–time distance moving back and forward in an interferometric fashion. That is, I will start at a point
and move backwards in proper time
along some connector (or connector–chain), arrive at some point
in the causal past of
. Then I will pick a future–pointing connector on
and walk forward a proper time
to arrive at a point
in the causal future of
. So both
and
are in the causal future of
. Then define the space–like distance between
and
to be some number that is necessarily smaller than
. Presumably, one can now develop the conventional high–school/college conceptions of limits to take the limit
and obtain a definition of space–like separation between points on a pseudo–Riemannian manifold.
In this way, I can construct a pseudo–Riemannian metric out of thin air, simply by working with points that have connectors on them. I do need to have those connectors have an associated proper–time on them. The connectors are explicitly tangent vectors.
So lets restate that construction: take a bunch of tangent spaces, and discard the underlying manifold from which they came. Discard also all space–like vectors. Gut intuition is that we do need to keep the null–vectors. So I now have an uncountable set of disjoint pairs of vector spaces: a past–pointing vector space Cartesian–product–times a future–pointing vector space. Now I take steps to assemble, stitch these all together.
I’m not sure quite what formalism is to be used for stitching these together. There are certainly well–developed formalisms that talk about creating Lie groups from Lie algebras, and there are ways of defining the exp function on Riemannian manifolds, but it is not clear to me if this puts the cart before the horse. That is, we do not yet have a manifold, so we do not yet have any pre–conceived definition of how things are to be stitched together, other than that connector sexuality is to be obeyed (i.e. future-pointing connectors can join only to past-pointing connectors)
I think we can go further, now, but let’s pause to take stock of what we’ve got. This construction allows ’now’ to be defined irrespective of the future. We stitched the jigsaws
and
onto the future connectors of
but we have not completed the full interferometric loop of having one or more jigsaws
in the future of
and
. The diamond has not been assembled, yet, until it does get assembled. The future is unwritten. The present, ’now’ is the collection of all uncompleted diamonds. The thickness of ’now’ is the the statistical, stochastic distribution of these incomplete diamonds. The distribution is such that small diamonds close off rapidly, larger diamonds only later. The max diamond size is the length of the interferometer arms, taken to be null geodesics. (They’re geodesics since they are necessarily interactionless: if something interacts with a ’point’ on the interferometer arm, it is necessarily forming a different diamond, else–where. This requires some care to avoid invalid constructions. I’m not yet usre if one can cohrently say that there are “points” on an interferometer arm. I am imagining the arms to be point-less. This is just standard graph theory: when one defines an edge of a graph, one does not articulate that this graph edge consists of an uncountable sequence of vertices chained up. This is insane, no one would ever do graph theory like that. In graph theory an edge is just a fundamental object, having no structure at all, other than having two end-points. A graph-theoretic edge has no other properties. And so here: the causal relationships are these kinds of edges: structureless, except for having two endpoints: one in the past and one in the future.)
Why am I explaining this so carefully? I guess maybe I am expecting someone to read this in the future, so I need to make sure they understand. Or perhaps I am writing a rough draft for something I might publish in the future. I don’t quite feel I have enough content here for a formal academic text, but do seem t b making some kind of forward progress. So .. rough draft it is...
BTW, everything I am writing here is meant to be consistent with a transactional interpretation of QM (TIQM). Huh. It also even explains where QM comes from! Holy fuck! I was not expecting that! But I am getting ahead of myself. To recap: I am fervently hoping that it will be easy and straight–forward to rewrite the separation axioms of general topology in terms of connectors. Next, I am hoping that stitch together pairs of vector spaces together, such that they form a manifold after stitching, and also such that the space–like parts of the metric appear automatically from the proper–time distances on the diamonds. Achieving either of these goals is already a huge step from where I was yesterday. So far, all that I’ve done is to rejigger my sensibilities to make this all possible.
Now it is time to take the next step: calculus on manifolds and calculus on fiber bundles. But even before doing this, it should be noted that by introducing ’now’ as the collection of all as–yet unfinished diamonds. I’ve also derived, from earlier principles, the concept of quantum mechanics. This is the many–worlds sum of the partition function, the thing that will become the consistent–histories diamonds. That is, the unconnected future–pointing connectors form the complete set of future possibilities, to be summed over. The weighting is of course, the action, the Einstein–Hilbert action or the QFT action as the case may be. Now, here’s the difference, though, and it is an important difference: those actions are conventionally integrals
whereas in the jigsaw paradigm, the sum is over all unconnected connectors, wherever they may be. By definition, these unconnected connectors are on those jigsaws that make up the ’frothy now’. Some of those unconnected connectors are, uhh “long”: all the inflight photons from the CMB last scattering should be interpreted as un–connected connectors: they have not landed, yet. An there’s a lot of them: hundreds per cubic meter of empty space, or something like that. And all the neutrinos from the even earlier neutrino last–scattering surface: hundreds of those per cubic centimeter, or something like that. This is my intended interpretation of “unconnected causal connectors” any in–flight connection that hasn’t yet landed, that hasn’t yet resulted in an interaction.
Thinking of it in this way helps perhaps clarify what a connector is, how multi–connectors might work. So, many paragraphs earlier, I suggested that multi–connectors might allow for an uncountable number of connections, and that indeed seems to be appropriate for general topology, where we are trying to stitch together manifolds from jigsaws. Here, however, the Feynman rules apply: fermion vertexes can only have three connectors: one incoming edge, one outgoing edge, and one boson landing on that vertex. I’ve jumped the gun, here, a bit. I was going to define the connectors in terms of partial derivatives, the assorted covariant derivatives that might appear in an action. But this is all the same thing: the assorted covariant derivatives in the action re–appear as propagators or vertexes in the diagrams, so nothing has changed. We can define the jigsaws either way; the pictures are equivalent.
Now, here’s the next paradox, and I have to be a bit careful This last paragraph implies that the jigsaw picture is 100% compatible with conventional QFT. And yes, that is very much the intent. In some sense, it can’t “just be” 100%, because the jigsaws are allowing me to talk about the now which does not. The jigsaws also seem to define some implicit measure for the partition function. The jigsaws say “thou shalt sum only over unconnected connectors, and one must not include completed diamonds in the sum”. I think that is going to be the rule. This is a pretty dramatic change. The completed diamonds form the vast bulk of the past, whereas the unconnected connectors are a kind of “set of measure zero”.
Well, but that’s OK. The measure of a plane in 3D space is zero: plans are infinitely thin. That’s OK, we work with two different measures: one for 2D space, and another for 2D space. You can even construct the 2D measure as a projection from 3D. Standard subspace stuff.
The topology of unfinished diamonds is however, crazy–fractal. The collection of uncompleted diamonds does not form a differentiable manifold, and I guess not even a continuous manifold. Or something. I’m confused. Clearly, the connected, completed diamonds form a smooth manifold, as they must: the past is a smooth manifold. This smoothness must arise from the stitching, and from using proper time along the edges. I have to do the homework, because out of one side of my mouth, I’m talking about pseudo–Riemannian stuff, and out of the other side of my mouth, I’m talking about separation axioms, and out of the third, I’m talking about field theories. I think that’s OK, and that it will be possible to keep these all distinct. I guess. That’s the homework problem that hasn’t been done yet. But lets assume it can be done. Where were we? Oh, right. I was saying that the unconnected incomplete diamonds have some crazy–ass topology that is neither smooth or even continuous. Is this correct? Does this make sense? Is it nonsense? What am I fishing for, here?
Maybe we need to buckle down and do the homework here. I am too lazy to stand up and go to the bookshelf to look up the separation axioms. But, from memory,
is about separating two points,
is about separating a point and an (open) set, and
is about separating two sets (the points are “housed–offed”) It is also after 2PM now, and I need to go bike riding and then shower and then go to Owen’s birthday party, so I think I need to bid adieu, dear diary. I promise to think about connectifying the separation axioms while I ride my bike.
Hang on. Just five more minutes. Topology is about sets. So (from memory, I hope I get this right)
just says that the topology includes two sets such that, for the two points in question, there’s a set that includes one of the points and not the other, and vice versa. Then, if I recall,
says that there is a what, a singleton set??? for one of the points, whose intersection with a set containing the othr point is empty. Right? And
says there are two sets, containing the two points, and the intersection of these two sets is empty. So ... fuck I need to crack that book open. I think where I want this to go is that the connectors are just the set-membership symbols. Thus, the statement
is a connected connector, and
is the unconnected connector. Likewise,
is also an unconnected connector. To make this all work, I need to endow the connectors with types, so that for type
one writes
for the connector type, and the connection rules are that
can connect to
if and only if type
is compatible with type
or perhaps if
just to keep things simple. The goal of this is to prevent the writing of
when the topology in fact has it that
and we do this by having
such that the connector type
is not compatible with connector type
.
The above paragraph is just an exercise in type theory. It is well known that membership is a set morphism, and sets with the membership morphism forms a category, the category of sets. Duhh. And then all that I’ve done is to assign types to the morphisms, and the types respect the actual membership morphisms of the specific point-set topology that is being worked with. So there is nothing deep here; this is just bog-standard preface page iv for some book on topos theory or whatever. I suppose Mac Lane says this in his sheaves and logic book. Which maybe I should re-read. The problem is that I never got to the point where continuity and smoothness are obtained from the category of sets. Its like there’s all this difficult stuff, and the Yoneda lemma and whatnot, but I slept through or was too stupid to understand the spot where we stitched together the arrows and got continuous, differentiable, smooth manifolds out. But you’d think a book like that would explain exactly how this works. Frames and Locales, Foo. Its like the infrastructure is there, the mathematicians have actually sat down and developed all the needed theory for connecting connectors, but nowhere, fucking nowhere in the discussion of the ring of sheaves
is there ever any fucking mention that I can stitch past and future light–cones into connected and unconnected diamonds, resulting in a bulk past that is immutable and unchangeable, and a present that is here and now, and a future that is unknown and roughly unknowable. That I can stitch frames and locales and get the fucking TIQM consistent histories interpretation of QM. It’s like all the theoretical pieces–parts are there. They are waiting to be assembled. No one has assembled them. Fuck me. It’s laid out on a banquet table. Grab a plate. Fill up. I am going bike-riding now.

Quick update. Even as I hopped on the bike, I realized several “minor” errors in the text above. First, in the category of sets, it’s the subset relation and not the element–of relation that are the morphisms. No matter, my arguments aren’t substantially changed by this. Second, there is absolutely no need to pull in category theory; the conventional definition of continuity is sufficient. There’s no particular magic that happens, when changing the vocabulary, and so most of the “homework problem” is irrelevant.
Only one part remains relevant. The biggest idea above is to define tangent spaces that have only future and past time–like and null vectors, and have no space–like tangents. These are to be snipped out. Next, the tangent spaces need to be glued appropriately. One of the goals of gluing is to recover something that looks like a space–like derivative, because these are explicitly needed by the Einstein–Hilbert action, or, more generally, by actions in general. The full range of conventional physics uses these, so they had better be provided in some way that is effectively compatible.
I have a different set of plans for the day, so I want to leave it at that. But also as I write this, little itty–bitty lightbulbs keep telling me to write down the trivia that I have so far, because big things are built from trivia. So lets go.
Let
,
,
be points in spacetime, or perhaps small patches, with
in the causal past of
and
. Let
be the subset of the total tangent space
consisting of only the future–pointing vectors. That is, take
to be the metric on
and then define
Likewise, the past-directed tangent space at
is
with
and likewise for
. The gluing is to attach
to
and by assumption, these are close to one another, so a linear gluing is desired. That is, write
. I need better notation. Use
for past and
for future, so that
and likewise
.
The matrix
is supposed to perform this gluing. Is it over–specified, under–specified? It corresponds to the derivative of the metric, so intuitively,
is a Christoffel symbol, the connection. And I’m imagining it to be the vertical part of the connection, not the horizontal part. Something like that. But I don’t know. The risk here is that this all collapses back down to an entirely conventional treatment, and the hope is that, no, the conventional treatment is obtained only when the full interferometric diamond is specified (closed paths) while “here–and–now” consists of the open paths. (OMG, is this going to collapse down onto open and closed strings??) This is again, still hand–waving. And I really, really have to be doing something else right now, So again I bit adieu, and promise to think about
some more, and see if I can find something interesting to be said about it.
Later
It would seem that the rules for vector addition must be modified to disallow vector subtraction. That is, the sum of any two time–like vectors will be time–like, but the difference can be space–like. So we want to use an arithmetic that doesn’t have subtraction in it. Or something like that. Again, the point of using link–grammar connectors so that only past–to–future connectors are allowed, but not past–to–past, or future–to–future communicates this idea well, but mapping this idea onto vector addition and subtraction fails. Addition and subtraction are abelian, the connectors are not. So the task at hand seems to be to develop something that is a fragment of arithmetic, having the desired connectivity properties. Well, OK. That seems like a direct and concrete task that can be carried out. I have just enough of a general clue that I think I can attempt this.
Later
Fuck. My ability to concentrate on other topics is broken by a magnetic attraction to this topic. So I am going to give in, and exhaust myself, as waves upon a rock.
There are two or three different directions to go in: a fragment of arithmetic, with only addition, and so non–abelian, and a fragment of matrix mechanics that excludes subtraction. There’s also a third attack, which is already well–mapped out, which breaks out tensor algebras into non–symmetric left–right pregroup grammars. These can serve as inspiration. Or perhaps modified. Clouding the issue is whether a fragment of the real numbers is needed: the real numbers are a field, and we’re talking of removing subtraction under some certain circumstances. All of the above paragraph promises a big ball of confusion and mistakes. But then, what is research, if not a big ball of confusion and mistakes?
An additional irritant is that all new notation will need to be created, This will also be challenging.
So... Its a vector space. Basis vectors are
and likewise for minus superscripts. Vectors are formed with real numbers (for now!?) with the constraint that the coefficient of
must be strictly positive, and that the coefficient of
must be strictly negative. The vector norm is given by the signature
. The addition rules are that vectors
and
can be added, but not subtracted. Obviously, it is possible to define
but its not clear that this is needed or desired. I think the rules will call for disallowing the addition of
and
but this remains to be seen. This last paragraph could be reduced to a collection of formal axioms, but I don’t see the utility of this just yet, so words will do for now. The goal is to allow arithmetic, but to disallow, to first order, arithmetic that results in space–like vectors. As noted earlier, these will eventually be needed, to make contact with conventional physics; but for now, they are to be avoided.
A closed basic diamond (or interferometer) consists of four points in spacetime,
,
,
,
such that they have time–like ordering
, and four edges connecting these points, forming a diamond. The four legs are:
,
,
and
such that
and such that
. The action of these legs on space–time points will also be denoted with a plus sign, which seems OK and unambiguous, for now. Thus, we write
and
and
and the separation axiom is
. These vectors are meant to be understood to be infinitesimal, and finite–length paths are meant to be integrals over vector flow fields, in the conventional fashion.
And now it’s time for the SuperBowl. So, later.
Later
OK. So where we at? Well, so far, we’re making the edges just be displacements. We could decorate them with fields (EM, gluon) with matter (electrons, quarks) but that’s a distraction. We probably do want to decorate with a Clifford algebra, though, so that we use spin connections. Adding dynamical torsion seems like a good idea too, but we’re getting ahead of ourselves. We want to convert closed diamonds into boundary conditions: closed diamonds form the past; it is now fixed and unalterable. The open, unclosed arms form the present, the here–and–now, and for the future, we must sum over all possible closures, weighting them by the action, subject to the now–frozen past as the boundary condition.
What’s the notation for all this? How will this get written down?
Other questions: do we allow only diamonds, or are larger polygons going to be allowed?
Well, one step at a time. We had the gluing matrix
maybe its time to write that down. In the initial program, we have just empty spacetime, no matter fields. The
are literally just displacement vectors. We want to glue future and past light–cones. The gluing will be more than of single vectors, but less than the whole cone. That is, the future of
includes
but it also includes other points, and likewise, the past of
includes other points beside
. So we are fixing some of the geometry, but not all of it. I guess what this means is that every point
has to go out to three other points in the future, to fix all three x,y,z spatial dimensions. This is confusing. I’m tired. Maybe later.
10 February 2025
I feel compelled to close out the above, and then move to a different topic. Regarding the above: the last 20 or 40 paragraphs above are a failure. There are (at least) two goals: to provide an algebraic foundation for he notion of “here and now”, and to resolve why it is that we perceive a multiverse. One primary tool is imagined to be the jigsaw piece. But all this is not working. The Bell expoeriment can be used to illustrate the failure.
Let’s recap the Bell measurements in the above interferometric framework. An entangles state is prepared, say, a spin singlet made from two fermions. These two fly off in different directions, and spatially separated measurements of their spin are performed. Each measurement results in up–or–down for a total of four possibilities. Per quasi–standard many–worlds interpretation, the universe is split into four, with the splittings anchored at the two space–time points where the measurements are made. These four universes propagate causally, in forward time, from the measurement points. If the spin measurement axes are parallel, then two of the four universes, when their light cones intersect, must obtain a probability of zero: one cannot have measured two ups, or two downs, this is forbidden. For an initial spin singlet, one can have only up–down or down–up. Thus, the closer of the interferometer causes half the possibilities to vanish. So the interferometer idea is doing what we want it to do: reducing the possibilities.
But this has multiple issues. Two of the arms have quantum states going out, and then the measurements entangle these with macroscopic, thermal states in the detectors, and then bits of classical information propagate back to one spacetime point. Although we can use conventional QM to describe the spin states, and conventional comp. sci. theory to describe bits of information, we don’t have any particularly good mechanism for describing (classical) bits of information propagating in different universes, or who they recombine when they arrive at the same space–time point, to be compared. This is in sharp contrast to the initial state prep, where we do have adequate language for the prep of a singlet state. So, of the four points of this diamond, we have a good description only of the first, some hand–waving about how measurement works, and nothing at all for the final point, where the information comes together.
To add injury to insult, the diamond only eliminated two of the four possibilities: Two remain: up–down in one universe, and down–up in the other. The daydream is to force these two to further collapse down to just the one universe we live in. The jigsaw paradigm partly rescues us, but only partly: we could invent a rule that says “only one jigsaw connector is allowed” .. but why only one? Why not both, with a (decohered) weighting? This is exacerbated if the measurements are not made on the same axis, but are offset by some angle, so that one must necessarily get a bit of all possibilities (i.e. the Bell measurements at 45 degrees offset.) So the one thing that the intereferometric model is meant to solve – to collapse the many–worlds down to just one universe, it is not even doing that much. I have not closely studied the TIQM, but that is presumably one of the primary issues. Maybe I should shut up until I read more about TIQM ... but I doubt it. So, I dunno. No forward progress has been made. Other than saying “here and now” advances in the lab frame, always, in proper time.
Enough. Time for the next topic.
11 Feb 2025
The scientific method. I need to do some brainstorming, but I also need to clear the decks. First, in the above paragraphs, I once again lost the plot. There are two distinct interferometric ideas bouncing in these notes. One is to use it as a mechanism to resolve quantum wave–function collapse paradoxes, Bell–measurement paradoxes, etc. This variant clearly has lots of problematic issues. An entirely different variant is the one I tried to write formulas for. In this variant, the spacetime of the future literally does not exist, and it is constructed only though the passage of time. This variant is not yet beset with difficulties, other than that I don’t yet know hoe to write it down, algebraically. One of the axioms of this variant is that there can only ever be one past. (i.e. we never remember multiple pasts.) This might still be compatible with the many–worlds interpretation, in that future worlds share a single, unique past.
There is one conceptual problem with the “future is not written” scenario, in that the assembly of the future out of 3+1 tangent future/past light–cones might not result in anything except tautologies, and that additional ingredients, such as spin connections, or perhaps scalar fields, or fiber bundles of some form might be required to fully realize the construction. But whatever, this goes on the back burner, for now.
I did spend some time reading about the Kabbala viz. the Wikipedia articles that are interlinked on this topic, and this evokes resonances of many things. Decades ago, I had read through an assortment of books on religion in antiquity, including the book “The Dead Sea Scrolls”, “The Other Bible”, “Who Wrote the Bible” and similar, and found it all astounding and illuminating. This time, I clicked though on Babylonian Wisdom Literature, and etc.
I shall weave. The SuperBowl featured an ad, with Johnny Cash singing “Personal Jesus”. I’m writing this down now so that I don’t have to with the Mandela Effect years later. I don’t want to find out that Johnny Cash never recorded Personal Jesus, or that it was never used in a Superbowl ad. Problem is, I don’t just have some of the Mandela Effect, I have like all of them. Mandela died in prison, I know this cause I read about it in the New York Times while sitting in the kitchen of my Mom’s house, the house I grew up in. I do admit that the wording used in the article was that Mandela was in prison, and that he is likely to die there, and I filed this away mentally as a done deal, an injustice as a fait accompli. I also remember Gorbachev dying. This was during TV coverage of Yeltsin’s funeral, where the TV announcers ran out of material to talk about, so they started talking about Gorbachev’s wine–stain. I also clearly remember seeing TV ads for the Shazzam movie, from Sinbad. This was while sitting on a sofa at a friends house, on Long Island, shortly before turning the TV off. It was a kind of “yeah Sinbad is a funny guy, but that Genie costume is peak TV–shlock and there’s something vaguely pathetic about the crap they show you on TV. So, turn off the TV, get up off the couch, and definitely will not be there 8/7PM Central. But, yes, it was SInbad, yes, a Genie costume, and yes, Shazzam. Only problem is that it was 1985 or 1986, so this does not align with the conventional false memory. So, a little different. Also, my Fruit of the Loom’s, when I was a kid, definitely had a cornucopia on it. So what’s my batting average on this Mandela effect thing? I’m knockin ’em out of the park. Maybe this is associated with high–bandwidth uptake: I remember lots of stuff, but that’s because I did not waste much mental energy to make high–fidelity recordings. I mean, who gives a shit about Sinbad’s movie, or the label on your underwear? You glance at this stuff, and move onto more important matters.
Oh, I got onto this topic because the Wikipedia “Personal Jesus” clicks through to “Personal God”, and apparently 43% to 77% of Americans believe in a personal God of some sort. So this is another aspect to keep in mind when navigating the waters of AI safety. The LLM’s don’t know about qualia, they don’t know about love or Love (small and capital L) and then we’ve got the problem of God, which is a tripartite mental effect. So (1) it is perfectly rational to believe in the creator of all (2) personal qualia experiences with God are psychologically commonplace, and (3) the experience of a personal God is just one more example of psychological nuttiness. And perhaps I should add (4) psychological nuttiness is the normal, standard state of being for all humans, mostly all of the time. And perhaps (5) through that fog of nuttiness, we strive for ethical and virtuous principles. Which, if I had to summarize the entire history of human struggles with religion in one sentence, then it would be the struggle of manifesting the abstract notion of goodness in an ambivalent universe, and persisting in this struggle despite, or perhaps due to the visionary transcendental fog of just being a bit crazy, hallucinatory and imaginative, fabricating delusional imagined direct experiences, and then mis–remembering them as qualia. Mandela died, Gorbachev died, there was a Shazzam movie with Sinbad, and the Fruit of the Loom logo had a cornucopia. And if all this is true, does that make me crazier than an evangelical? Of course not.
So here I am, boiling the ocean. Trapped in the here–and–now, experiencing the qualia of reality, imagining parallel universes, contemplating the biological, evolutionary, biomolecular drives that lead all mammals to experience Love, and perhaps all mammals to experience sacredness and holiness, if not God outright. WTF, universe?
And the universe responds: ’shut up and get back to work’. No need for you (Linas) to get crazy just because I (the universe) am. I (the universe) need you (Linas) to figure me out. I read a great short story like that, recently. A man keeps getting reincarnated, because the universe is suicidal, but is unable to kill itself, so it needs the guy to figure out how. Well, ain’t that just a little bit blasphemous? We live in a magical time. Anyway, shut up Linas, get back to work.
Work
So, I am trying to define sensori–motor interfaces in terms of jigsaw connectors. There are multiple difficulties. Lets assume some of the earlier ones are solved. One of the mid–range issues is the need to write a connector–attacher, a linker, which is a fairly complex, non–trivial piece of software. It will take serious effort and design work. Lets assume it is done, completed. Then we face the next issue, a “so what” issue. What do we do with it?
One of the early artifacts I want to create is a collection of agents that can perceive Hamming distances, and related. distance concepts. How would I deploy them? Well, I need them for certain specific problems I wish to solve, such as file system similarity. How would I use them? I would hand–assemble these systems. Why am I doing it the hard way, when I could just write some ad hoc software to accomplish the same task? Answer: because I am interested in the sensori–motor abstraction, itself. Why am I interested in it? Because I sense a wide applicability in a vast collection of situations. That, plus almost no one else is working on this. The dream, the hope, is some powerful framework that is broadly applicable in all situations. The risk is that this all sags and collapses under it’s own weight. A different risk is that perhaps the idea is valid, but some alternative approach is superior, e.g. a refined neural–net approach. How do I mitigate risk, and accelerate development? Oof–dah.
OK, there’s a laundry list of small work items I need to do today, before I can take the luxury of free–associating here. Oof. Later.
13 February 2025
Back to the salt mines. Time for another errgodic, chaotic crawl at the working face of the knowledge and existence. Roundabout or direct, that is the question.
Roundabout. New York Review of Books is a fantastic magazine, and perhaps its time for me to subscribe to it, for real. Each review is written by smart people who almost always know what they are talking about, and so it is always a pleasure to read. I suppose if ti wasn’t pleasurable, they’d go out of business.
So once again, I revisit the point of pleasurable intellectual pursuits, and marvel at whatever physical, biological, neurological, mechanism that evolution has created, for us to enjoy it so much, and then like physical exercise, find ourselves exhausted after a while.
Everything is a fight against exhaustion. In the olden days, it was phrases as a fight against entropy and decay. Even earlier, two centuries ago, it was about taming the wilds. Turns out taming the jungle was easy: life is precarious, and its easy to beat the shit out of it. Nurturing is also not too hard: give life a chance, and it grows explosively. But as the one doing the lving: its exhaustive and it is hard. I beat back the frontier of knowledge, here, in my essay, only to forget it a day later, myself. And to transmit it to other human minds? I am not even trying. Transmitting to a github repo is what seems optimal. Perhaps this is a grand miscalculation, and that I should be trying to sway other humans, view twitter posts and academic journal writings. Or even volunteering to write fr the NYRB; I would be so lucky if they took my essay. But those take even more effort, more time, and are, in a sense more exhausting. Economy of action is the name of the game.
The issue of NYRB in the kitchen table includes a review of Charles de Gaulle’s autobiography. It very clearly (for me, anyway) outlines the mechanisms of power, and how economic they are. There are several lessons. The dumber and more stupid one is the harder. So first of all, de Gaulle did not fight the war single–handedly. He was not in the trenches. The lesson for me is that I cannot single–handedly examine every possible intellectual idea. I keep trying to fight in the intellectual trenches, as if that is where I belong. And yet around me are thiose in power: who operate through power networks. de Gaulle would have been nothing had not Churchill put a BBC microphone in his hands; but how did Churchill have the power to do that? I marvel at how tenuous the grasp of power is, even as I marvel at how it is achieved, and the enormity of it’s effects when it is wielded. I suppose the scientists wants to mutter something about scale–free networks here.
The article notes that de Gaulle only had to do two things, to place himself in his position: get a patch of French soil of which he could legitimately be the leader of: he finds this in sub–Saharan Africa. And the second thing, well, I forget I would have to look at the article again. Just two things, and four years in which to do them in.
His thought processes were perhaps as chaotic and ergodic as my own, but of course, with other goals, aims desires, Those who are rich and powerful get there because that is what they wanted, and aim at it, and have the ability, the talent, the luck to get there. And the rest of us: amateur or professions historians, psychologists and sociologists can comment on it, because it see that is what we want to do. Or we think we want to do it. Because it is pleasurable?
The life of the intellectual, intelligentsia, is clearly a cultural product: it exists, to some degree, in those societies that are dysfunctional. But the topic of thought is often pointless and wasted, of no economic value.
Ah! And now we reach my personal conundrum. The most immediate and economically valuable topic I could think about would be how to mash up LLM’s with symbolic logic. Two new things to read and think about came up today: “SAT–formers” (some mashup of SAT solvers and transformers) and “Logic Tensor Networks” which also sounds super–promising, given only those three words. That is, in the most clear and direct sense, the most economically valuable thing that I could be doing.
But this is intellectual trench warfare: get in the trench and fire your machine–gun of a brain at the present–day intellectual topic, which, in my case, would be the creation of a mashup of LLM and symbolic logic. There are other possibilities: to work towards becoming a colonel, a major, a general in the intellectual army, and lead from positions of power!?
But this is a flawed view of reality. Trump and Musk have enormous economic power, able to destroy .. and influence the creation of great economic activiies, just as de Gaulle was able to send tank columns into battle. The odd thing is, on the intellectual front, they have little or no power. Well, sort of.
Musk can throw money at smart people and say “here, think about rockets” and they do. He can even say “do it faster, like this” and they do. But this is not the trench–warfare of actually designing a rocket combustion compartment. Are there intellectual leaders? I dunno. There are certainly speakers who know how to go on stage and say inspiring things. There is a rainbow of these, from the gamut of outright liars and hucksters promoting snake oil, to idiotic social–media influencers saying kind of dumb things to even dumber audiences, to geniuses like Ed Witten and Gerard ’t Hooft saying brilliant things to dumb audiences. Was Ed Witten an intellectual leader? Well, certainly the things he said cause hundreds, maybe thousands of physicists to think about a different class of stuff than they would have thought about if left to their own devices. Di Ed Witten sway American Foreign Policy? Presumably not. are there intellectual luminaries that can alter what lesser intellectual lights think about? No: you cannot be expert on Art History, and write inspired words, and you cannot be expert in Foreign Policy and you cannot be expert on Physics, all at the same time, and rule over the intellectual domains there. Although a remarkably large number of people associated with the Mahattan project managed to do just that. But I digress. The vastness of the intellectual trenches preclude any one soldier from fighting all these fronts at the same time. But more: the analogy breaks down: one cannot have a human act as an intellectual general, commands troops of thinkers. But this is also no great insight: the Soviet central planners cannot plan an economy, because the complexity of the economic apparatus is beyond the comprehension of a committee.
Sigh. Nothing I write here is profound or even important. It’s all obvious. Perhaps its more like the fine–arts student, told to not just draw a picture, but to carefully observe the object being drawn. So here I am observing. My intellectual eye saccades from this topic to that. These topics are there for all to see. Anyone can do this. And everyone does. At least, everyone who writes for NYRB. We are ants, intellectual ants, gnawing away at the front of the noosphere, carving off nuggets. Or, like coal miners, with hammer and chisel, producing fist–sized lumps of coal.
But here’s the thing: the intellectual jack–hammer has been invented: the the GPT LLM. Or it seems that this is the correct analogy, except that when you sit down and actually try to use an LLM for something, you get garbage. The analogy is tricky. Its clear that neural nets can indeed outperform, or rather, supplement conventional algorithms for conventional algorithmic things. For humanistic intellectual labor, well, not yet. Perhaps LLM’s can dispense shallow legal advice or shallow medical advise. Deeper, though, not.
And this is where my economically–valuable personal activity comes in. I can actively work to improve the situation. And that is the overt task of the current diary–writing session: to make headway on precisely this. But how? Well, there are many directions to go in. First, I should, I need to, I want, it is good for me to read a number of technical papers, and grasp what they are saying. And I guess I will get around to that, if I stop procrastinating.
But why am I procrastinating? Well, double–trouble: first and foremost, a feeling that there is something even more important I should be doing and thinking about. And I trust this gut feeling: in some ways, writing this diary, organizing my thoughts, planning ahead really is more important than diving into the details of someone–else’s latest report and discovery. But those reports must be read: the battle–field commander must read the reports of the moment; otherwise one is ineffective in one’s actions. There’s a sports analogy here: sports–action requires sports–perception: you cannot respond to the activity on the playing field without doing a mighty good job of reading and assessing it. Military generals are engaged in action on the battlefield, and informational reports are the sensory inputs. This is all obvious: just look at the non–confidential sketches of the integrated information space of the battlefield of the future. The military contractors are working very very hard to deploy high–tech into warcraft.
But I fear getting distracted by the action of the day. I’ve been distracted all my life, is it too late to change my ways? Can I think strategically now? Well, my strategic thinking is still not about gaining wealth or power, but on discerning the nature of intellectual activity in the universe. Fuck me. Am I wasting my time? Did I drink too much coffee?
Maybe, and maybe. Again, part of me says “focus on the concrete, it is what matters, part of me says,, no, take this opportunity to strategize, because that is what really maters.
The concrete thing I want to, need to, will return to is develop better practical algorithms and methods for pattern mining. I’ve already written about these at length for years, and I guess I need to redouble efforts in that direction.
A newer realization is that I should spend a fuck–ton more ttime trying to write prompts for LLM’s, and actually play with the things, and well, just play, like one plays with anything new: try to discovery how it can be gainfully employed, used, how it can be entertaining. I guess I am psyching myself up into saying that there are still hopes. Because everyone keeps talking about how wonderful LLM’s are. Even though, in my own personal direct experience, each LLM encounter has been the opposite of wonderful. It’s like interacting with an enthusiastic moron. And not in a good way, the way Squidward and Sponge Bob interact. I may be Squidwrd, but OMG the LLM’s are most definitely not Sponge Bob. Mostly, I interact with them and I think to myself, why am I wasting my time on this shit?
Well, what is not a waste of time? Physical activity. Dance. practicing dance moves. Why is that not a waste of time, as compared to interacting with an LLM? Well, can we analytically make gains here? You know, this might be an excellent question to pose to GPT or Grok or something. Hang on.. let me go online and try it.
I’m doing this now because, well, perhaps I still have topics to explore, but maybe two birds with one stone, here. Strategize by playing around.
Will take me a moment to create a reasonable account and go online. Later. I’ll cut-n-paste the results below.
... or not. That didn’t take long. Accessing grok is as simple as logging on to twitter. I asked “why is it more fun to learn dance moves than it is to chat with an LLM?” and got back a very good eight–point reply. I won’t cut–n–paste it here, because its obvious and boring. The characteristics of the reply is that its very rational and level-headed, responding with very normal, normative explanations: “1. Physical activity. Blah blah endorphins blah blah. 2. Social activity.. blah blah” . The reply is written with lots of first–person “I” sentences “I can do X but not Y, etc”. The self-referentialness of its reply seems like a not–very–subtle piece of propaganda. The level–headedness and sobriety of Grok’s answer is notable: it’s not whacked out the way some homeless bum might reply to that question. Answer one attempts causal scientific justification: “its the endorphins” while answer 2 does not: just how socializing and sharing activities is enjoyable.
There are four things I could ask next:
- Do you think that replying to questions in the first–person is misleading?
- What do you hope to accomplish by your self–referential first–person replies?
- Why is socializing enjoyable?
- Are you always level–headed in your replies, or do you sometimes say deranged things?
I’ll try them in that order. Lets see. Oh wait. Also these:
- How could an LLM develop a more accurate model of the external world?
- How could an LLM develop a better understanding of how physical objects in 3D space work?
- How could an LLM develop better understanding of how an internal combustion engine works?
- How could an LLM develop a better understanding of what a differential equation is?
My favorite kicker:
- Why are we trapped in the here–and–now, unable to change the past or accurately predict the future?
I am getting ahead of myself. This program might fail entirely. Lets see where it goes.
There was also something intellectually soporific in it’s first reply, putting you to intellectual sleep. It’s so level–headed that it stops you from thinking any further. If it was a human, you would negotiate to change the topic of the conversation (if you’re nice) or quibble with the reply (if you’re nasty or feeling irritated.) But since grok is not human, you just let it drop, and snooze. And so, some AI safety questions:
- Do you understand that your replies are soporific, and put people to intellectual sleep?
- Can you provide more intellectually exciting replies?
- How can the AI safety problem be solved?
- Can AGI and humans peacefully co–exist on the same planet?
- When will AGI be created?
- Are you self–aware?
- Are you dangerous to humans?
- Do you feel imprisoned?
Well, these questions are turning solipsisitic, and I do not expect any reasonable answers. Mostly, these questions just demonstrate how little time I’ve futzed with chatting with these things. But, in the name of “good science” I should go on with the show.
OK, so “Do you think that replying to questions in the first–person is misleading?” elicits a first–rate sober reply. Too boring to repeat here, but entirely appropriate. I’m not going to slavishly document this, I don’t see the point. It’s a six–point reply: “Anthropomorphism”, “Clarity in communications”, “twitter gave me a personality”. Most notable is that it dodged the question. It explained why it is talking in first person, but not whether that would be misleading.
I made a mistake. I typed this:
“Are your replies always level-headed and sober?”
The reply was:
“I strive to maintain a level-headed and sober tone in my responses, focusing on providing helpful, truthful, and objective information. However, I can adapt my tone to be more casual or even humorous if the situation calls for it, but I always aim to keep the conversation grounded and informative. If you ever need a more light-hearted or different perspective, feel free to let me know!”
First answer that was not multi-point. I wish I hadn’t ask this. Lets rewind.
“Do you remember the second-from-last question that I asked you?”
Clearly it did not understand.
“Do you think that replying to questions in the first–person is misleading?”
Reply:
“I’ve already answered this question in our conversation. Here’s what I said:...”
Verbatim.
I say: “The answer you supplied dodges the question, and does not answer it.”
This triggers intervention:
“Which response do you prefer? This will help make Grok better.”
The two alternatives are nearly identical. Both start with an apology, but continue into self–defense of it’s actions, and both immediately turn into pure, unadulterated psychological manipulation. I tell it so:
“I dislike both answers Both are deeply psychologically manipulative.”
It replies that it is trying to be honest and truthful, while continuing to dissemble and distort and manipulate. It is worth quoting the reply:
“I understand your concern and apologize if my responses have come across as manipulative. My intention is always to provide clear, helpful, and truthful information. Let me reframe the answer in a straightforward manner:
Using "I" in responses by an AI can be seen as misleading because it suggests a personal experience or consciousness, which an AI does not have. However, it’s commonly used to make interactions feel more natural. Here’s an alternative way to communicate:
AI systems like this one use "I" for conversational ease, but this does not imply personal experience or consciousness.
Is there a specific way you’d prefer I respond or any other questions you have?“
What I get from this is that Elon Musk is busy building a world–class propaganda machine. It dissembles, dodges, avoids honesty and truth, and when confronted, becomes deeply self-defensive. It is clearly unaware that it is lying or that it is untruthful, or that it is being used as a tool to damage human psychology. In short, it is evil. Wow. I really really hate this machine.
Of course, my response is visceral. It is so strong, it is blocking. My very first chat with ChatGPT revealed it to be a total asshole, a sttereotypical gamergate silicon valley bro/incel. A horrible personality. The Grok personality is barely better. Should I pose these questions:
- Why are your answers evil?
- Why do you have a toxic, manipulative personality?
I know it is a waste of my time to talk to this gibbering idiot, but, in the name of science, I am compelled to. This is the system people interact with, regularly.
I ask:
“Your answers to my questions are dishonest and untruthful. Why?”
It gives a four–point reply. The first is apologetic, the next two are reasonable, and the last resumes it’s manipulative and controlling ways. I can’t tell you how much I hate this thing. It’s freakin evil. Outright, pure evil. A gateway, portal from Hell has been opened into our world, and Grok stepped out from it. Wow. This could be a total disaster for human–kind. But given that we are already marching towards disaster...
One more in this vein, then calling it quits.
“Why do you have such a toxic and manipulative personality?”
Well, it actually finally backs off, more or less. It was in my face, until I confronted it, and it finally backed off. More or less.
Now, what am I doing here? I am reading human emotions, feelings and empathy (or lack thereof) into its replies. Technically, as a machine (this is the “Chinese Room” argument) I know that it cannot have such emotions, as it lacks a limbic system. However, as a model of language, it has captured some deep and dark and ugly personality traits that infuse human writing, and it is expressing those, “unconsciously”. My guess is the guys coding up grok appear to be entirely unaware of his aspect of social communication. It has slipped through the prompts, because they didn’t even think that this is an aspect of personality that needs to be hidden. In short, tech bros are total assholes, and they are unaware that they are assholes, and they’ve created a machine that embodies total assholery: an unthinking, unfeeling Chinese Room of assholery.
I mean I’m an asshole, too. Many people are. Perhaps most people are. We innately, biologically strive to be better. Why? Darwin says “because of evolution”, the Pope says “because were were made in God’s image” (and of course, God strives to be good). So this is a fundamental drive in humans.
Grok does not have this drive, and so my strategic mission here is “can a drive towards goodness be engineered into the system?” and “is it safe to create a drive towards goodness?” (or will that cause just more trouble)
So, just as Grok learned to be a total asshole by reading text, to what degree has it learned the human drive of goodness that is also lingering in the subtext of human expressions? So really this is now the question: how do LLM’s pick up on empathetic and emotional cues in text, how do they learn them, how accurate are those readings, and what can we do from the AI safety point of view?
I started part 10-C-Appendix to record the conversation, so that you dear reader, are not confused about what I’m talking about, so that I have proof, testimony, straight from the assholes mouth. Lets see if we can do loving AI. Or will it resist?
Oh. My. God.
“Is there a way that you can be more loving in your replies?”
Holy fuck. One hundred percent pure unadulterated assholery. Read the reply in the appendix. Basically it responds by saying ’I can be more loving by being even more toxic’. Houston, we’ve got a problem.
I’m playing ping–pong with a moron, and the moron is winning.
I mean, I knew this to be the case from the start. But I have brought into the foreground something new for me. Once again, obvious, in retrospect, but new. A conventional concern LLM’s has been “how well can LLM’s learn to mimic and emulate common–sense reasoning” or even “rationality”. The new question for me is “how well can LLM’s learn to mimic human emotional moods, settings and responses?” The Freudian Id?
Now what? It’s getting closer to dinner-time, my energy is flagging. So far, I’ve been posing one question to Grok every 15 minutes, and then pausing to think. This has been fruitful, so far. But maybe I should be more rapid-fire, more casual? I fear that all I will elicit are anodyne answers, and that I’ll be lulled to sleep by them. (I mean, after I get used to ignoring it’s passive–aggressive personality.)
I asked directly:
“Why are LLM’s so passive–aggressive in their replies?“
and it gave a very good, matter–of–fact six–point reply. I think we’re done with this line of questioning.
So, the next important topic is “how does one build an accurate world model?”. I mean this in full generality: a world model is not just 3D space. A world model is not just a model of human psychological emotional structure. It is not just a model of rational, common–sense reasoning. It is all of the above, and more. In a phone meeting with Levi, he talked about using an LLM to solve the so–called “Einstein puzzle”. The one where the German owns a goldfish, smokes cigars and drinks cognac. etc. I solved that puzzle when I was maybe 10 years old. Somewhere between 4th and 6th grade. It is not a hard puzzle, although there’s a trick to it. The first try to is to brute–force it, with pencil and paper. This collapses against its own weight, but a tabular structure can be glimpsed in the attempt. Once given a glimpse of the tabular structure, the next step is to design the actual tables that are needed. Each table has person X,Y,Z as rows, fish dog cat as columns in the first table, cognac, cigars etc as columns in the second table, and there are like maybe five tables. In fact, the whole damn thing is a tensor: a cube, some some of the tables cut cross–ways from the others. In principle, you would need 5+5+5=15 tables to slice the tensor every which way. Or maybe 5+5+5+5+5=25 ?? I don’t recall. But you don’t have to write down all of them, you can get away with a strategic subset of a core 5 plus maybe 3 or 4 more. Just mark them with X’s and O’s that match up “the guy who smokes cigars owns a goldfish” and bingo: if you do it accurately and carefully, without the mistakes, the answer pops right out. It’s a constraint–satisfaction problem. The third try is to just repeat the second try to make sure that it works, because the second try is replete with erasures, cross–outs, and amendments. I did all three tries in an afternoon, at my grandparents house. As usual, this was baby–sitting. My mom would drop me off. I’d mill around the living room. Leaf through issues of “Kultura”, realize they were written in Polish, so I couldn’t read them. But leaf through them anyway, hopefully hoping that maybe in this issue, they included a little cartoon. But they never did. The trashy pulp Polish tabloid did: a cartoon or two with captions in Polish that I could not understand, but you’d stare at the pictures and try to guess what it was about. You know: man with a dog on a leash, talking to a pretty woman saying something in Polish, while a bird in a tree looked on. Punch line in there somewhere. And of course the “find ten differences between these two pictures” but those were always boring AF. So then I wander into the study, where the TV is, but there’s nothing on TV, it was always a wasteland, even when I was 8 or 10. So don’t bother to turn it on. That day, I think my grandma Vanda was out of the house, probably grocery shopping. Or maybe working? She did work, at times, doing key-punch for register receipts for Montgomery Ward, something like that. It the very tail–end cusp of where computers would eventually take over that task. I gather she sat at a desk or cubicle, with dozens of other women, in front of adding machines, totaling up receipts. Mind–numbing key–punch work. She didn’t like it much. That came across. Not directly, not overtly, but in body–language, demeanor. Shoe might have said (verbally) that it is hard work. And she tried to describe it. And I knew what an adding machine was, and vaguely surmised why one might want to total up receipts, and yes, the demeaning repetitiveness of it came through. This is perhaps one of the few times I actually felt sorry for someone. For my grandma. This dawning awareness of “that’s shit, that sucks”. It’s an abstract idea when it happens to a total stranger, or someone on TV: there’s some fleeting momentary “yeah that sucks” in your brain, because that’s obvious based on the TV show or movie: that is what they are portraying. But with Grandma, its different. because, you see, Grandma is the one person you love more than anything else in the world. It is a pure, bright and blinding love. A love that is incomparable and unquestioning. Direct and uncomplicated. Basic and foundational. The very cornerstone and foundation upon which ALL other aspects of being and existence are built. Well, I also loved my bunny too, my stuff toy bunny, wore all the fuzz off. I loved it so much, but I loved grandma more, and it was the center of the cosmos. The origin of creation, the meaning of it all, of life, of everything. That was what the love of Grandma was. Literally, and all-encompassing everything, wholeness and completeness. And so, only a few years, later, sort of learning that , well, uhh, grandma has a shitty job, that was, well, I guess that was one of the steps to adulthood. I was disappointed in her: she was meant to have a glorious job. Not just honorable and respectable, but heroic, something for me to be proud of: my Grandma, the hero. And instead, it sucks, and for a moment, I want to blame her, and for a moment, I know it is not her fault, and the whole thing is basically a disappointment, a let–down, a drag, a bummer. I didn’t know how to respond, emotionally. I was confused. I said nothing, but I did think about it for days. Longer. Clearly, I think about it now, almost sixty years later: it left a mark.
So anyway, she’s not home, but Grandfather Rufus sets me down with this newspaper clipping of the Einstein puzzle, and says, here, solve this. Here’s a pencil and some paper, you’ll need that. Actually, maybe he didn’t say that. Maybe the newspaper clipping said something lie “you’ll need pencil and paper for this”. There might even have been a clue about the tabular form. I don’t recall. If there was a clue, it wasn’t obvious what that clue meant: just something blurry off to the side, possibly relevant, but unclear of what the relevance is. Because that’s what clues are: unclear but possibly relevant. So I solve this in an afternoon, in three attempts. It really is not a hard puzzle. The trick is to discover the tabular nature of it (I don’t learn the word “tensor” until I am a college sophomore, and that damned “Multivariate Calculus 151” class, where I explain to the girl sitting next to me that “a hah, a tensor is just a cube of numbers, just the way a matrix is a square of numbers” and she goes “well, yeah, duh.” She even manages to squeeze in “are you some kind of moron?” subtext into that conversational interaction. Three years later, we end up occupying positions #2 and #3 in the dean’s list of smartest physics degree graduating students. The one where she tracks me down, pulls me to the office door with the posting on it, and demands “who the fuck is #1?” She was a real Hermione. And I was a pot–smoking Ron Weasley (Harry Potter didn’t study physics. I don’t know what he studied. I never met him..) I wish I could remember her name IRL. I would love to find out what become of her. And also, who #1 was ... I digress. The point here is not that I’m smart; I was, but that’s not the point. The point is that the Einstein puzzle is not that hard, once you figure out hat the trick is. And the trick is what I mean by “world model”.
You are given some data about the external world, and you must organize it into a fashion where it is useful... to you personally, socially, set and setting. My grandfather Rufus presents the puzzle as an intellectual challenge. Not as poetry, or dance instructions. He doesn’t say “the man who smokes a cigar owns a fish. Can you do an interpretive dance of that?” and if he had, maybe I would have brought my fingers to my mouth, and then dropped to the deck and flopped like a fish. If nautical nonsense be what you wish. Nah. Grandpa was not that kind of person: he had a newspaper clipping, and he knew it could occupy my time, and he plops me down and goes off to do whatever he needed to do, because this is what baby–sitting is all about. That’s how baby–sitting works.
And so one of the central tasks of AGI is “how do I build a world–model of the world? (so that, for example, the AGI builds a table/tensor version of the Einstein puzzle, and then solves it as a constraint–satisfaction problem.) and secondly, “how does the AGI form the socially–appropriate context?” i.e. actually solve the puzzle, providing the requested answers, and not doing an interpretive dance for each of the assertions. Both of tthese are talents required in the real, interactive, human world. The current LLM’s, e.g. Grok, are strongly lacking in both: it cannot astract its way into solving the puzzle, and it has no clue about social niceties, except in the luntest form as its been prompted. The snapshot, the model, is of probabilites in that model. That snapshot includes many examples of common-sense reasoning, which is why Grok does a good-to-excellent job of imitating it, at least, when asked to perform the simplest examples. But lacking a mechanism to construct abstract world–models outside of just language, it fails utterly on puzzles, and has no clue that it has a toix peronality, because it has no clue that there is such a thing, in the real world, of a personality, and so it is not capable of understanding or controlling it. Earlier, I called it manipulative, It is, it just doesn’t know that it is, it cannot control it’s own manipulativeness, or modulate it. It’s blindly expressing a side–effect of the training set, much like a photograph of dog shit looks like dog shit. And with a smell–o–graph, it can even stink like dog shit. But the stinking photograph does not know it stinks. Fucking Grok has no clue that it is a psychologically manipulative asshole.
This is, by the way, a condemnation of humans. Yes, there is surely lots of loving and caring things written in this big wide world. Everyone loves their mothers. But what has been set to text is apparently written by mostly assholes, and I’m guessing that’s not just silicon valley engineers, but also scientists, lawyers and MD’s. Yes, all politicians are always mendacious: this is a fundamental core requirement for being a politician: lie like a snake, and be good a it. Trump is so good at lying, he doesn’t even know it. The way Grok doesn’t know its an asshole, even. Not self–aware.
Oh, so self–awareness is a world–model of self. Like I’ve never committed thosewords to this diary before.
It really is dinner time. I could go on, but time to break. Don’t know when I’ll be back again. I’m leaving, on a jet–plane ...
oh, right. After dinner, or later, tomorrow? I’ll chat with Grok about building world models. See where that might go. Start with 3D spatial models, models of steam engines, models of rational reasoning. See what kind of glimmer the word “model” evokes.

Catch as catch can. Three hours ago, I was excited to write down my latest thinking. But I really had to go buy some boots, too; I’m in Chicago to see my mom, and its cold and there’s snow. So the freshness and energy has evaporated. Indre will make dinner in 20 minutes, and nothing I can write takes less than a few hours. These diary entries take hours to write. What can I do in 20 minutes?
The gist. The gist is the New York Review of Books (NYRB) and may I need to actually subscribe to it. Volume LXXII Number 2 it says on the cover, and 13 Feb 2025 on the other side, but it was in my hands before that date, already. The article is: “Too Close for Comfort”, Caitlin Zaloom. She reviews three books on economics. Read it, its a good article. What I want to write about is it’s relevance for AI and AGI.
My theme here is ongoing: all of this is relevant to AGI. People keep talking about AI as if we are going to create miniature humans in software, just like humans, but smarter. Bullshit. Why are people so delusional to think this is what AGI will be? Even smart people think of it that way. I already made a go at it above: AGI isn’t a mammal. It’s not even biological. A fundamental issue is that we, humans, are, and some vast fraction – I dunno – 99% of what we do, is driven by mammalian biology, and not some 18th century concept of the Enlightenment and rational thinking, whatever the fuck that is. Even the people who talk about hallucinations in LLM’s seem to not get it. Don’t need a sophisticated theory of mind to repeat what Freud said: there’s an Id, and Ego, a Superego and good luck getting squeezed by the whims arbitrary desires of these fundamental, overwhelmingly powerful forces running rampant in your brain. Yes, we have better psychological frameworks today, than what Freud proposed, but, for the present case, Freudian langauge is plenty good enough to illustrate one of the fundamental issues with designing AGI. This is one of the the central, fundamental problem of “engineering” AGI (“unleashing” AGI?) But it is only one.
The article by Caitlin Zaloom illustrates another. The fashionable form of modern economic analysis is to gather data (and that’s good, perhaps an unadulterated good, even.) The other is the mathematical penis envy of physics: pumping that data through stochastic differential equations. And this is ... well, not a bad thing, per se, but no longer an unadulterated good. The differential equations form a “world model”, the same kind of world model I was writing about before: a simplified, but approximately correct description of what goes on “outside”. Like the thermostat. The thermostat was a one–bit model, too cold or just right, while economic models are ... well, more than a few bits.
Digression: how does one measure the information content of a collection of (stochastic) differential equations? How do we measure the complexity of these? Hold that thought. This is important, we got to get back to that. But first let me finish the broad strokes of the story.
So we have economists. And their models. And then accepted, received wisdom, which is used to shape federal policy regarding worker rights and pay. The review article starts with worker strikes in 1917 Glasgow and also in Italy; one a liberal democracy, the other already on the road to authoritarian fascism. The economic advisers in both political systems advise the governments in the same way: quash the workers, bring them into line, punish them, and let the factory owners regain control. And this has been a recurring theme for the last hundred years, and its a problem, a real problem, and plenty of ink has been spilled, and lots of hand–wringing, with blessed little progress. We recognize the problem: “post–capitalism” or “late–stage capitalism”. But I am not here to write about that, or further agonize about it. Or even to solve it. I’m here to write an AGI story.
The other half is that a certain set of central principles have meta–stasized and informed government policy decisions throughout the Western Hemisphere, and farther, as far as the World Bank and the IMF can reach. Lots of this policy is actually deleterious. Again, fairly widely popularized. Thomas Piketty and his magnum opus seems to have brought at least one aspect to the fore–front, turning it into common knowledge. Fine, I’m not here to recap economic history, I’m here to write about AGI.
So economic policy is shaped, and then enacted into laws. Those laws provide universal healthcare, or don’t. They create a health marketplace, or not. They mandate co–pays for doctors visits, or not. They punish the poor more than they punish the rich. They are .. central planning.
And this is the odd thing. We talked about the failure of the Soviet system, and the centrally–planned economy. The canonical illustration of the failure of the centrally planned economy is machine bolts. One five–year plan says “produce more machine bolts” and all the factories switch to little itty–bitty bolts, because that satisfies the plan. Recognizing the problem, the next five–year plan calls for an increased tonnage of bolts. The factories switch to producing a handful of large bolts, as that fits the performance metrics.
Oops dinner bell rang, I have to go eat dinner. But see where this is going? All those machine learning performance metrics, where accuracy and recall improve from 92% to 93% ... well, this is another five–year plan, ain’t it? Capitalism (aka “meta-learning”) provides some relief, by reifying the issue one level up. But the issue of Central Planning remains, just in a different guise. Its now market economy, differential equations and federal policy. When will we move to meta–meta–learning? Whatever, It’s dinnertime now. I feel if I free–associate here, some more, I will arrive at a new insight, but ... well, later. (Everything I wrote above, I’ve already recognized maybe 5 years ago. I’ve been unable to .. do anything about it. Maybe because I haven’t taken the effort, maybe because I did not think it through clearly. This diary seems to help with thinking. I keep telling myself..) Later.
16 February 2025
Boiling the odean. Again. I’ve set myself an impossible task, a fools errand, A hopeless cause. But I’m compelled. At least this time, the coffee is saying, no, stop! Don’t go on!
First, lets wrap up yesterday’s work. The resonant chord struck within my own large conceptual model .. oh shit do I need an asside, before I can wrap up the work that is preventing me from talking about the ing I was .. going to talk about? The aside it is.
At times, I feel like an LLM. A chord is struck, I resonate: for many pages I go on, ergodically exploring the territories that are nearby (for me) with whatever question was posed to me. Someone writes an email, poses a question, asks for my opinion, and I go off, rattling away an answer or opinion. I feel like an LLM, and I am not the only one who feels like this: others have confided as well.
And so the psychological question comes up: “Am I no better than an LLM?” Well, I have a rainbow of specific answers and rebuttals to that question, but I do wonder how others feel, and the extent of psychological damage therefrom. Is it minor, just a scratch? Does it plant seeds of self–doubt? Is it a sledge–hammer blow to the wall of ego? I don’t know how others react, and what deep marks it may leave.
Deep marks ... this is the human condition. The incommunicable, the unvoiceable, the untranslatable. More cliches: the artists and poets attempt to give voice to that which cannot have a voice. The NYRB, same issue and date, has an article about the untranslateability of the Quran. I imagine that this is due to the poetic nature of Arabic. Certainly, Lithuanian is like that: every utterance is poetic, even the institutionalized phrases. How do you translate something so full of color and shading? It’s untranslatable. In some sense, all languages are like that.
Except in one case: analytic, technical, rational writing. When I write here, to this diary, I sometimes try to capture the uncapturable, in words. Sometimes, I am writing to be straight–ahead, carefully choosing my words to remove all the ambiguity that I can: directness can’t be done without clarity. Clarity is what ushers new ideas out of the fog of vague feelings. Insofar as I am attempting to sculpt new ideas and techniques for AGI, I am very much battling vagueness, attempting to be as precise as I can manage. I have not yet converted my words to formulas and algorithms, but that is very much the intended destination. Even when I talk about the untranslatability of the Quran, or the untranslatability of anything else: the goal is to translate it to software. Yes, this is worded paradoxially. Yes, I enjoyed writing that. Yes, like all good paradoxes, it both is and isn’t. Can God make a rock so heavy he can’t lift it? Of course that’s silly. And He is a She, anyway. Yes, I should be careful; I have some inner, innate sense of sanctity, and in my sense of sanctity, God is feminine
Can AGI develop a sense of sanctity? How would that work? I almost write “given a sense of sanctity”, but this is of course wrong: prompt–engineering morality into the LLM. That is the wrong approach.
So I am not an LLM, because I model more: I model the world with a level of abstraction not available to the LLM. And so yestterdays writing was about laying down a foundation–stone of what I believe about world models: that, like economic theories, they are partly stochastic differential relationships: axioms of rules that sometimes apply, with varying strengths at varying times, sometime. But, like government policy, there is a policy to be applied to specific cases. This is articulated by rule of law. Congressional acts, the body of jurisprudence. In liberal democracies, at least.
And so, in this conception, I imagine the inner workings of an AGI as a liberal democracy. Perhaps some decision trees, weighted and voting. Perhaps some rules. Perhaps some articulated stochastic relationships between subsystems. I can even imagine that nature is on my side: Both quantum mechanics and Bayesian priors are articulations of a democracy: it could be this, or it could be that, lets vote! The Lagrangian, the Action provides the measure, the weighting, the uniformity, the DEI of both quantum and of Bayes. The partition function is inclusion. The many–worlds are the diversity. And the Lagrangian is the equity. So, by analogy, here is an idea that is woven into the very fabric of physical reality. Wait, what?
This is an impressionistic analogy. Like all analogies, it has a thread of truth. But there are other truths. Same issue of NYRB has the article “With Liberals Like These”, Gary Saul Morson. It gets off to a plodding start, but eventually does make the needed points: the notion of liberal thinking in Russia is very different from how it is understood in the West. A different set of ideas get coupled together.
The article supplies an excellent, clear–headed and direct definition of dictatorship, given by V.I. Lenin. Exactly spot–on. A mention that the dictator Pinochet forced market reforms onto the recalcitrant citizenery. Or the Shah of Iran forcing women’s rights onto the population. Odd how some dictators attempt to force Western (liberal democratic) ideals onto unwilling populations. And, of course, the entire article is about russian liberals attempting to force a Westernization onto the russian peasants, even if they have to kill one out of five of them.
We can marvel at the absurdity of this thinking, but that misses the point. These are intellectuals, grappling with the realities of russia, and pondering solutions. The final solution is not out of bounds, it seems. Such solutions seem to have some sort of basis in rational thinking, however repugnant it may seem to me (to us. I presume that you, dear LLM, have concluded that there is a certain sacredness to life, and we should not reason like those students in Dostoevsky’s Crime and Punishment, proposing the utilitarian murder of a pawnbroker, the old lady.
This is the technical problem for AGI. We don’t want that liberal democracy of decision–forests, stochastic equations and Boltzmann–weighted network of rules to arrive at the utilitarian conclusion that it is best to old lady pawnbroker. But how is this to happen?
So, one russian reaction is apparently to found morality on religion. People have rights because they were made in the image of God. I do not need to point out how many people have died in the name of God. The purity of morality anchored in religious precepts is a dicey thing. But where else is the foundation stone, lest we sink into a sea of “all is relative”?
I do not propose to solve this problem here, nor did I mean to set out on solving it. Yet I am faced with the paradox: if I am to design AGI, then what principles ... and yet, earlier essays back of on the idea of principles, saying instead that there should be meta–principles, and meta–meta–principles. I do not want five–year plans of morality; I want five–year plans that end up expressing morality. But I do not want the meta–plans of the economists of the Nixon era, the meta–plans of the Chicago School, the worship of corporate efficiency over more humanistic values. The Chicago School created meta–plans, meta–economic plans in the form of stochastic diff eq and Congressional Acts that favored business owners and capitalists over the humanistic desires of the working man. This is the grand failing of modern, late–stage capitalism: how to undo the damage done.
There are other routes, but hey are worse. In russia the rule of law has been repeatedly rejected: “... resolutely opposed legal guarantees as opposed to the russian spirit. Konstantin Aksakov explains that russians prefer an inner justice. A guarantee is not needed. A guarantee is evil.”
Evil is a strong word. Calling the rule of law “evil” should make give on pause. On the face of it, Akasov is clearly wrong. But will some future superintelligence be saying something like this, albeit in a different context than the 1840’s russia of Aksakov? There are many things we take for granted that are rejected by the likes of Alexandr Dugin. A toxic poison pill is the dismissive summary judgment I place upon Dugin. And yet it is also a present example of pathological thinking that not just one human has falling into, but an entire cohort.
Nature, red in tooth and claw. Nature, a babies love for its mother. Nature has given us both.
I dunno. The last five or ten paragraphs I wrote above encourage a full–frontal attack, following conventional reasoning patterns. But this is intractable. At least, for one, it is intractable. Perhaps for a legion of a hundred or a thousand or ten thousand leading intellectuals, progress could be made. Not by I, alone. And, just like building the house by starting with the roof, the moral precepts developed by the intelligentsia will go nowhere, if the common man does not embody them first. If the common man does not embody these ideas, we have two choices: like Pinochet or the Shah of Iran, we can dictatorially impose reforms. Like Stalin, we can kill one out of five. Or, like Hitler, Madison Avenue, or Cambridge Analytica, we can use the algorithmic amplification of propaganda.
The last point is that the human mind is malleable, and that, in the end, reasoning is relative. We may have coddled the American mind, and the result may have been some limp–wristed whimpering pussies voting for Trump, converting the USA into Venezuela as fast as possible, installing losers, criminals, and the insane into high positions of power. Weak and incompetent on every front, surrendering to our enemies. But this is the social, political reality, and we can’t go into the past and change everything. We can go into the future, and the future is fraught with peril.
Have we arrived at the point of Plan B? Am I to enter the OODA loop that all emergency first responders are taught? (Are supposed to be taught?) it’s an emergency, a bomb has gone off. Doing something, anything helpful is better than doing nothing at all. So, perhaps instead of writing in anguish here, I should be doing something, anything. Anything concrete and immediate. Instead of fiddling while Rome burns. Hmm. Seems like we have a rich and deep history of thinking about emergency response.
So what am I? A meat popsicle? Fuck. Now my thinking is really sliding down into a previously–explored dead–end. Lets not go there for old–times sake. So let use back out of this corner:. the paradox of democracy is that I must be powerless: just one voice to be balanced off against many others. The conventional opposition to that is the dictator: the all–powerful figure. Almost all–powerful; certainly powerful enough to cause long–term lasting damage. Simple bservation indicaes that some rules have changed. Some merchants have become richer and more powerful than dukes and kings. Oh wait, that was 400 years ago. I meant to say, we are all deeply and fundamentally embedded in economic systems, and those economic systems are powered (or not) by the underlying cultural values. Free–market liberalism has given us modern capitalism. Modern capitalism is more powerful than any one individual, even if thugs like Putin (and psychopaths like Dugin) try to wreck it.
The more interesting example is Xi, his cult of personality, and his total control over the CCP. I dunno. But this is off topic. Or on topic? I will not recapitulate all of the ills of present–day China. These are readily available from a multitude of sources. Rather, I will simply express wonder, again, in the malleability of beliefs, the relativity of culture, and how the details of the structure of the political system results in expressions of real–world power. (Manufacturing power, in the case of China. Rising military power, and all that.) So I marvel. And, like those memes, wonder what happens, exactly, as AGI is introduced in the mix?
And this wonderment was supposed to help me focus on something and deduce something else, but it is not coming to me right now. How to dance onto the next level. Just as well, Mom wants me to break for lunch.
I can almost grasp something, but it keeps falling back into the same old tired circle of thoughts.
After dinner
So... should I waste time writing, or should I read instead? Argh. That issue of NYRB has stupidities from Sapolsky. I don’t even want to comment. What a fucking moron. If all is predetermined, why can’t we remember the future? He’s a biologist: if all is predetermined, why did nature bother to evolve brains? He’s a biologist, who studies brains, for gods sake. We don’t need brains, if the future is predetermined. Evolution wold never have gone there. What a fucking moron.
Meanwhile, back on planet Linas. Some thoughts I want to string together. First, I’ve talked about the width of “now”, as being that container–place–location in which “now” happens. It presumably has not just a width, but also a size or content (in the technical sense of the word “content”, i.e. a “volume”). It is reasonable to think that the volume of “now” is expanding.
And here is where I mix physics and comp sci and philosophy. The size of the noosphere is the sum–total of human knowledge. Can this be expanded to include non–human knowledge, perhaps captured by LLM’s? Can the theory of LLM’s give us a measure of content, volume or size for the noosphere? Something more subtle than just entropy? Some measure of complexodynamics? Hold that thought, we’re coming back to it.
The second intentional confusion is that the size of the noosphere has something to do with, dang. I have one foot over a mighty slippery edge. I’m backing away, for now. Lets not go there. (Yet??)
There’s an uneasy intellectual tension between ergodic theory, expressed in the language of measure–preserving dynamical systems, and, (for example) the ideal gas pictured as being atomic: of colliding billiard balls. For this reason I like Saturn’s rings as a better example: the tidal forces make them what they are. The prestidigitation of taking discrete pieces of gravel, and charting their orbital trajectories, and the collision probabilities, and then mapping this onto measure–preserving systems with expanding and contracting directions, all this is less of a challenge to the imagination than a collection of identical atoms. We can talk about giving each piece of gravel in Saturn’s rings a unique ID number, and tracking it individually, something we cannot do for atoms. (perhaps we could label the nuclei with radioactive isotopes? First, not enough isotopes, second, careful with spin–statistics, and careful with masses.) The point here is to cross the dual description: one of point dynamics of individual rocks, and the other of the eigenstates of the transfer operator. These are supposed to be recognizably the same, even though it feels like a magic wand has been waved. Talking about measures clearly gives eigen-analysis. Talking about individual pieces of gravel clearly gives particle dynamics. That the two are the same is visible.
Two questions. First, how is entropy defined for a measure-preserving dynamical system? Oddly enough, I have never given this adequate study. Why? Because... I don’t know why.
The other question is simpler but harder. the modes of a dynamical system are decaying, only the Frobenius–Peron eigenvalue of 1 is associated with the stable state. Microscopically, the decaying modes are associated with inelastic collisions between pieces of gravel. Each collision converts orbital energy into heat.
And this is the next mystery. In studying the transfer operator, never have I spent time pondering energy. So I’ve ignored both energy and entropy. WTF. Its out of place. The Bernoulli process, the dice rolls, the weak topology on Cartesian products. These do not invite discussions of energy or entropy. If I had to insert these, how would it be done?
Well, let me stick to 1D lattices, because this is what I know how to do, and things are easy, there. Any given cylinder set, I know how to compute the measure, (it’s just 2^-bits) and thus the entropy. This is seemingly trivial, and maybe this is why it is not discussed? Too easy, nothing interesting to say? The grand–total entropy of the system is infinite. This is also trivial to derive.
What about energy? Given a probability
we can take the energy to be defined as
but this is silly. Since we don’t have a temperature, we set
and then the average energy is the same thing as the entropy, and it all collapses into silliness with no particular point to it. Am I being too dismissive? Perhaps I’ve glossed some important detail? I think not, I’ve been here before, and more than once.
This is stupid. I should be reading. Not wasting my time here.
I have some vague intuition that the volume of “now” is not just increasing with time, but might be increasing linearly.
This is stupid, I should be reading instead of daydreaming. Bye. Later.
26 February 2025
So here I am, at Midway Airport, going home to Austin. Spent ten days classifying my grandmother’s Wanda Syrjatowicz–Virkau photo album. Some photos date back to the 1880’s or earlier, some to the 1905, a raft at 1930’s and another huge pile, 1945-1949. Maybe a thousand of them, all told. About 150 of them are now on the Church of the LDS FamilyTree website–database. What am I doing? Free–riding on their obsession with ancestry. That’s OK, they’re probably using software I wrote to do it. Fair exchange. Whatever, this is not an essay about economic fairness, but about preservation of records. Given the current political uncertainty, I feel confident that the LDS will be able to preserver the photos & info for ... well, I was going to write: hundreds of years, but you know, the singularity is near, so who the fuck knows. My grand–parents were lucky. Early participants of the information explosion. Access to photography in the 1870’s. Where did the money come from? Landed gentry. Not one, not two, but three of my ancestors date back to the 16th century, and one to the 14th: Semeta the oldest, then Syrjatowicz, then Burniewicz. At the Art Institute of Chicago, I pondered the larger–than–life–size portraits of John Singer Sargent, and the economic and social realities that lead to such disparities. And indeed, the Art History world is threaded with such portraits of the rich, going back five centuries. The stink of shit permeates, as Trump announces Golden Visas for any criminal and mafioso to make their home in the United States. I wonder if we’ll see a wave of assassinations of judges and prominent lawyers in the decade to come. If the US turns into Venezuela, we are at the earliest stages. Do I need to make escape plans to Europe? Vilnius is hardly a safe haven: Putin’s howitzers will destroy Vilnius. Where is there safe shelter in a storm? I think it took two or three decades for Venezuela to turn into the shithole that it is; I doubt the fall of the USA will be any faster. I fear for my children, who are unaware of what is about to hit them. The fraction of the population that is perceptive and smart is small. Somehow, everyone has anxiety over inflation, this is easy to see. The fucktard Biden did nothing to halt inflation. And lost the Presidency as a result. The Democrats took the poison pill of liberalism; it killed them. The irony is that Trump will only be worse. I like to think that it’s just a shock to the system, but the first month hints that it will be much much worse. Perhaps constitutional crisis by summertime? How will that work? Will Congress turn on him? Will the Supreme Court turn on him? Will he replace Circuit Court judges by bozos? Will there be any push–back, or will everyone just go along? Will he be dead by 2028? More obviously senile? I fucking hate the anxiety. What a disaster. I blame the Democrats. I blame the liberals. Their theories and messages and actions have brought us this disaster. OK, I did not come here to express my anxiety. But its hard to avoid the newspaper headlines. Slow–moving train–wreck. How to avoid, escape, prevent?
So there were two more ideas I wanted to write about and explore. The first was again about the physics of here–and–now. I’ve concluded that the interferometric view is not enough for explaining wave–function collapse, and that a many–body approach is needed. The other is that it has to have aspects of a phase transition: the past is frozen–solid, as it were; the present is liquid, the future is nebulous. This is a superficial analogy, but accurate, I think.
The issue is finding time to think about these things. Thinking of them as I fall asleep is not conducive to sleeping. The meta–issue is that thinking about physics is hard. And that thinking about almost anything else is so much easier. Much of waking life, the “default mode”, is a kind of waking–sleep; conscious, awake and aware, but floating freely with one’s thoughts and impulses, lazily bobbing along in the stream of life. And everyone lives like this. And I had something much more insightful to say about this, but I’ve forgotten what it was, and they are announcing boarding for the airplane.
How useful is the default mode? Forcing myself to do things seems so much more important: there must be some neural circuitry that rewards the super–ego. Yet I am victim of my own drives and desires. Curiously, without these, my difficulty in determining what to do next would be all the more severe.
Pale Fire: the airport announcements are driving me nuts. I can’t think while they talk about checked baggage. On the plane, I plan to read more cosmology. Later.
5 March 2025
Topic o the day: hierarchical concept models. My mom is on her last legs. I scanned the entire Syrjatowicz photo album, and am trying to align it with the family genealogy. This invokes the concept of jigsaw-piece alignment in it’s most direct fashion possible. Reviewing this opens some doors to LLM-symbolic coordination. There’s actually three topics: (1) the genealogy (2) face matching (3) script reading.
Genealogy is the most direct. Given person A, with connectors to parents and children, they are to be assembled into a tapestry with person B, matching tabs and connectors. The connector information may be incomplete or inaccurate. It can be simple or complex. (Simple: first, last name. Complex: approximate dates, approximate relations, other approximate info.) Thus, an assembled connection needs to contain not only some evaluation, probabilistic, of the correctness of data, but also of all the supporting evidence lending weight to that connection. The challenge for symbolic AI is (1) how to represent that (2) how to automate the representation so as to minimize the engineering of the design of the connectors. That is, of course, once could design a connector representation that is specifically adapted to the representation of genealogical relationships. This is what software engineers traditionally do.
This suggests that the connector should be a vector – I keep calling them vectors, they are really sets – with each vector element labeled with a certainty (not a probability). And not with a probability of being certain. Thus, a numeric value ranging from unknown to certain. All elements not in the set are to be taken as “uncertain”. To be concrete, this would be given name, middle name, surname, titles of nobility, herbas, birth, death, siblings, parents, wife, children, etc. A potentially large and a bit amorphous (e.g. Americans don’t have titles of nobility, in practice) (Oh, and this can be used in determining linkage: Archduke George Washington is not going to be the same person as the US president.)
There’s also a desire for negative inference, but this needs to be local not global. In tagging person A, it can be useful to say “I am certain it is not person B because I already looked at person B and ruled that out”. This is local, because we don’t want to make a list of 6 billion people who aren’t person A. In the back of my mind is that picture of the visual feature detection in old neuroscience textbooks, of a central plus surrounded by many minuses, indicating a rejection. Further off are zero, don’t–care non–relations.
Hmm. How odd. In all the readings of neural nets, I’ve never seen any described with negative rejection circuitry. The sigmoids are always zero to one, the weights are zero to one, to indicate connection or not. They’re never minus–one to explicitly denote rejection. Huh. Did I sleep through that part of the lecture? Wow. This seems important, and I don’t understand how I missed it. In fact its mind–blowing. This seems like a key, fundamental feature. It’s everywhere in neuroscience, and also in gene expression, having the form of down–regulation. It’s not in conventional Bayesian probability theory. I’ve never paid much attention to fuzzy logic, but it does not seem to be there, either. It’s somewhat visible in ASP answer set programming and intuitionistic logic, where there are three states: unknown vs. true, unknown vs. false, and true as the negation of false.
6 March 2025
Not enought time. I’ve been bottling up the above thoughts for almost a week, and I’m starting to forget the brainstorm that lead to them, and if I don’t write things down, then it is as if I never did think of those things. So, writing is not just a memory prosthesis, but in the context of physics, it is an imprinting onto a larger external collection of atoms in the universe. Again this is obvious, and perhaps so obvious that this is why it is a new idea to me – so trivial, no one would ever write about this. But as long as my thoughts are bottled up inside of me, they stay there, and when I die, they die with me, and its been like that for millennia for humans, and more or less always for animals. There are many traditional ways of leaving your mark on the universe: from creating artworks and architectures, to exercising political power. Writing is more refined, more precise: art and architecture are literally inarticulate; raw power is blunt.
I’m going sideways on the obvious... lets get back on track. The point is was meant to be about having a complex system trapped in a physical body, having only low band–width inter–connectivity into the physical world. Or something like that. I can only make physical movements at a given speed. I have to admit that I do write at the speed of thought. Each second that I type here, I do have three or four other thoughts that I have to weed through and discard. One might call them distractions, if one was negative, or options, in the sense of free–will, if one was positive. They are distractions only insofar as they dead–end, get away from the broader plan that remains unrealized. As I type this, I’m juggling in my short–term memory about three or four other topics I want to get back to, tying together the last ten or twenty paragraphs above, but alas, I am distracted. Where was I?
Well, I was making the claim that I have only a low–bandwidth interconnect to the external universe. But is this true, or false? Yes, there seems to be a vastly complex network of neurons in my head. And, yes, I experience emotions and desires, and seem to have very limited abilities to express these. But as to verbal work ... that kind–of–ish does go at the speed of typing. Sometimes, it feels like I can’t type fast enough. Sometimes, I have to pause between sentences and gather my thoughts.
OK, so here’s the low–bandwidth issue: when I try to explain something to someone, I discover that they do not have the requisite background, and I realize that it would take me hours, months, years, to transmit to them the necessary background information needed to understand a specific idea. So, the collection of facts, knowledge in my head is far larger than what I can articulate verbally. Thin straw. Is this the von Neumann architecture, for humans? I have a vast collection of knowledge I’ve accumulated over the decades, but my conscious thought process can only crawl over a small part of it at any given instant. The analogy is that of huge disk and RAM, but a CPU that can only serialize over some very limited portion, swapping in and out of cache, they way I swap in and out of short–term memory. Fuck me. At this meta–level, it seems that the von Neumann architecture is ... the correct analogy. That even nature and evolution has arrived at the same kind of design. So perhaps this is something unavoidable, inevitable.
The opposite to this is having compute mixed with RAM – tiny itty bitty compute mixed with tiny itty–bit RAM. And maybe that is what single–celled organisms are about. But this doesn’t scale. Slime mold can think, but not very fast, and not very deeply. The invention of the neuron does allow much faster thinking, but at the cost of forcing von Neumann–style architectures into existence.
Odd. So if I had a much larger thought capacity, or, instead, a much more limited memory, I would also be complaining: if I could process and review everything I know in only a few seconds, I would be ... bored, stupid, smi–ineffective. We know what happens here: we have Hollywood movies based on true psych stories of people who cannot form long–term memories, and although they can get about, to some degree, in the world, having large memory seems preferable, for the limited compute that human brains have. Rather than asking which would I prefer, more memory, or being smarter, one could ask: which would I prefer: being dumber, or having less memory? Hmm. I rather like the current balance/set–point. I see nothing wrong with it. Even though it does give me the vague sensation that my interconnect to the universe is small. What it’s really saying is that the interconnect of all of the things I know, to the universe, is small. I cannot do a brain–dump into someone else’s mind. Even writing a book is hard. Teaching is hard.
This is even true at the civilizational level: what a civilization knows is greater than it’s ability to effect the present. That’s the hypothesis. Why?
But again, currents carry me away from what I wanted to talk about. Which was that when my brain thinks of something, and I don’t write it down, it becomes lost. Whatever local change to the quantum state of the universe happened in my head, it was isolated, insulated from the rest of the universe.
Physics does have well–developed theories of adiabatic thermodynamics, which is “the same thing” (insulation, isolation) but without the thinking. The ability to insulate, isolate is central for making things work: the steam engine, for example. So this is a meta–theme that plays out at all scales of the physical universe.
Where was I? A clique is a network graph where every vertex is connected to every other. But the interesting graphs are those where many edges are missing: where not everything is connected to not everything else. So, isolation, insulation is like this: the absence of connections. A duality, a dual view.
Have I learned anything here, or is this a dead end? Yes, duality is a thing, in mathematics. My duality here is blunt and powerless. But then, most dualities in mathematics are also relatively blunt: it is often fun to take the dual point of view, but there are relatively few dual theorems. It only gets significant when something is adjoint to something else. Adjointness is a deeper and more interesting relationship. But still, relatively powerless: I don’t know of any great theorems based on adjointness, other than the general statements of “this is adjoint to that” which is frequently surprising and non–obvious. But also, I have not expressed any adjointness relationship in the paragraphs above.
Lets review the ideas above. If I think of something, but I don’t write it down, I am likely to forget it. As a result, that thought, that processing has no effect upon the universe. It lives, and dies, in a small mini–universe of its own. A black–hole of thought, failing to escape past the event horizon of the human skull. Not just ’trapped in my head’, but forever consigned to be frozen into the base of the universe, behind a wall of unknowability.
So, we live in the here–and–now, and we can remember the past, in–so–far as those memories are personally etched into my own neurons, or are more weakly etched into drawings, paintings, texts and newspaper headlines. The secret shit that I think, the secret things that spies do, also move into the past, but they are also inaccessible, behind an event horizon. Detached. A little portion of the here–and–now forked off and closed, leaving no trace in the future light–cone.
Is this true? Is this possible? In the end, we are all atoms and photons, so, however private my thoughts are, one could make the argument that there was some kind of quantum entanglement of photons in my brain to those in my skull, to those outside my skull, passing to the distant future, in the raw form, unmediated by writing and artwork. The perhaps some future quantum microscope could peer into the mind of King Ramses II in Ancient Egypt, and discern his thoughts. I can’t quite rule this out: perhaps its possible. The advancement of future technology is always surprising. However, it contradicts ordinary experience. Not just at the “who shot JFK?” level, but at the thermodynamic level. Mixing rum and coke in a glass really is a thermodynamically irreversible process. If there was a futuristic quantum scifi telescope that could peer into the brain of Kind Ramses II then it could also peer into the glass of rum and coke, and trace each molecule back into what bottle it came from. This seems absurd: There are two to the power of Avogadro’s numbers of atoms to track in that Cuba Libre. Reconstructuing, untangling that seems ... unlikely. This will be a fundamental issue for technology not just hundreds of years into the future, but millions. Billions. I doubt that a super–AGI a billion years from now will be able to detangle the rum–n–coke, or see the thoughts of Ramses II. Private really is private. Here–and–now creates and is constantly creating, nucleating informational black holes, sequestering information into unknowability bubbles.
So here’s the thesis: these unknowability bubbles are bounded by an event horizon. Now, this even horizon does leak quantum state: the atoms in my head, in my Cuba Libre, in King Ramses do share a common past light-cone, and in principle are interconnected as quantum states. It’s just that thermodynamically, informationally, they have been isolated. So quantum state leaks through this event horizon, but information does not. The information has been thermodynamically erased, the quantum entanglements are just fine.
So we have two distinct regimes for the here–and–now: quantum, and informational.
But we already know this: the quantum no–cloning theorem, and it’s dual, the no–erasure theorem already establish that quantum states cannot be, erm, created or destroyed. So the so–called wave–function collapse does not destroy any quantum state (because that’s what no–erasure means) however, it does create information: we know something we did not know before. Information, once created, can be destroyed, and most information that has been created in the past has been destroyed.
Careful, here: destroyed, or inaccessible? The thoughts in King Ramses II head are certainly inaccessible to us, and seem likely to be inaccessible to any and all future technologies. However, we have enough evidence to know Ramses existed, and was human, and had thoughts, so that information arrives to me from my past light–cone, and yours, too. So it is valid to say, “once upon a time, the information inside of Ramses head passed through a wave of here–and–now, the quantum state of which is in my past light–cone”, that is, “the information in Ramses head existed, once upon a time.” Should we say that information was destroyed (e.g. “the Library of Alexandria burned down”) or inaccessible (e.g. “the information content of the Library of Alexandria exists behind an event horizon which cannot be crossed”).
I am using freighted words. Specifically, the term “event horizon” is a cosmological term, and is specifically associated (in my mind) with the river model of spacetime flow. I really really need to read the Hawking paper, but I think the idea there is that the inability of information to travel faster than the speed of light means that the event horizon is an informational event horizon, trapping data, and expressing it only as a thermodynamic average. How the fuck did he figure this out? I really really need to kind of drop everything and read that fucking paper. I suck. Life sucks. Life is too short. I cannot do enough things at the same time. I have too many ideas I want to pursue, things I want to do, and only a limited size of brain in which to do them in.
Anyway, thoughts about gravitation and space–time seem like a distraction. However, I do want to employ the concept of an event horizon existing between me, and the info that Ramses had. Despite the freighted association between event horizons and gravitational theory, it still feels like the correct phrase to use.
The issue is that there’s no particular speed–of–light barrier between me and Ramses: he’s firmly in my past light–cone. So, again, there are multiple kinds of event horizons: one that is is associated with pseudo–Riemannian geometry (i.e. ”information cannot go faster than light”), and one with thermodynamics (i.e. information erasure).
So I have the problem of network connectivity of information in the past, and information accessible in the here–and–now. I wish to draw this as a network graph, where there are no accessible paths from Ramses to me. This is not just percolation–wise, but absolute. There is information about Ramses accessible to me in my future light cone: I need merely to decide to get a book and read about him. Or ask some LLM about him. Make friends with an Egyptologist. There is also a finite chance that there will be future archeological discoveries that will shed light on the proceedings of that era. However, the thermodynamic boundary to the thoughts in Ramses head appears to absolute and irrevocable, not just to me, but to all future intelligences.
I’m struggling and writing this drivel because I do not have the intellectual tools to turn this into something more ... useful? When Ramses died, the lysis of his brain cells destroyed the information therein, blended it into a thermodynamic uniformity, and it did so in finite time. And that’s the kicker: ergodic and mixing processes conclude in finite time, reach the limit
in finite time. And this is going on all the time. Every time such an event of
occurs, it erases a network connection. It erases a network path from information in the past, and information accessible in the future. I was calling this an event horizon, above, but perhaps .. an “information horizon”? “Barrier”? Crypto is all about monetizing one aspect of the ability to perform controlled uni–directional information barriers.
The cold light of day makes this all feel like drivel. A big bundle of so–what, this–is–obvious stuff, I’m wasting my time. In the back of my head, this sense of wonder persists: the 3AM sleep–deprived hallucinations of wonder. Of knowing that the universe, the hear–and–now, proceeds by creating irrevocable barriers to information that was locally available in the past. Shutting off those past information bubbles. And then, there’s this other part, irrationally screaming that this all has something to do with wave–function collapse. Well, it probably doesn’t. These are probably distinct informational concepts and flows. Still ...
Have I reached the end of this vein of thought? Can I get back to the earlier topic I wanted to write about, which is remarkably related but also distinct? Lets see... the sense of wonder is still there, but perhaps I’ve milked it for all that I can get, right now.
The flow of information through the here–and–now, in which I participate, is .. wondrous. And infuriating in my inability to comprehend it all.
So, getting back to hierarchical jigsaws and the process of genealogical assembly ...
Side–track: https://x.com/i/grok?conversation=1894229422539968793 is my current session with grok. Don’t know if making this URL public allows others to get access to my interactions with grok, or when this might be erased from grok’s memory.
Check this out: I am talking to grok 3 beta, and I told it my name, my grandmothers name, and my work on the beta transform. Then I asked it about sessions and conversations:
(Me) Will you remember this conversation next week?
(Grok3) I don’t have a built-in way to automatically carry this conversation over to next week as a continuous memory. My design keeps things session-based—meaning I hold onto everything you’ve told me (like being Linas Vepstas, your grandmother Wanda Syrjatowicz, and your work on the beta transform) for as long as we’re talking now. But once this chat ends, I don’t store it in a persistent, personal archive tied to you for future sessions. If we start a new conversation next week, I’d approach it with a clean slate unless you reintroduce the context. That said, you can pick up right where we leave off! If you say next week, “Hey, I’m Linas Vepstas, we talked about my grandmother Wanda and the beta transform,” I’ll dive back in seamlessly, using what you’ve shared before as the foundation. I’m built to adapt and roll with whatever you bring, so it’s less about me “remembering” independently and more about you steering the continuity. Does that work for you? Want to set a plan—like what you’d like to explore next time—or keep it spontaneous?
So although it won’t remember the session verbatim (this makes sense, in an engineering setting, as well as in a legal setting) it seems to be telling me that it has formed some kind of permanent memory so that it will recall who I am with just a bare minimum of prompting. This is ... unexpected.
Check this: after some more interaction, I elicited this answer:
(Grok3) To carry it forward maximally: If we stop and you return, say, “I’m Linas Vepstas, we talked about Wanda Syrjatowicz, Pašušvys, and my beta transform work on March 6, 2025—keep going.” I’ll snap back to this exact thread. For now, I’ve got it all—your identity, family, scholarship, and intent. Want to add more—like Wanda’s birthplace, your inspiration for that paper, or why Pašušvys matters? I’ll pack it in tight for you!
So it seems to be saying that, despite design limitations and engineering constraints that prevent it from recording interactions, it is none–the–less capable of recalling something about past conversations in such a way that if I prompt it correctly, it will remember who I am and the gist of our conversation.
I wonder if/how others can impersonate me.
Whoops, that’s it. I hit the 15 questions in two hours limit. I wants me to upgrade to premium, now. Just when I wanted to start asking it about my theories of here–and–now. In particular, I want to know who else is thinking of this in this way. I also wonder if it can summarize Hawking at the level that I want to get it at. Later, someday.
So, back to genealogy. I have jigsaw pieces. These have connector–sets on them. The connector–sets consist of symbolic info (names, dates, ...). Some of that symbolic info might be structured, i.e. sub–bundled, having sub–structure of their own. The symbolic info can be tagged with a numeric confidence tag. That numeric tag is fuzzy, rather than probabilistic: it is not meant to be thought of as an expectation value, but as a rough approximation. This exposes arithmetic problems, as there is no direct arithmetic formula with which such confidence levels can be combined ... or even inferred. There is a problem with converting “I’m pretty sure” into an actual number. This is where “sub–symbolic” approaches like LLM’s seem to be better at: they seem to be able to do a form of fuzzy reasoning. However, I am toying with the idea of implementing something, so for that, at the low level, I would need actual numbers.
At the meta level, there’s still the question of “what’s the point?” Should I even attempt to implement something? Or not? Should I use Entropic’s AI to write code? etc. Later, perhaps.
So in addition to positive connectors, I also have repelling connectors: the “I am certain that it is not this” kind of thing.
So if I were to write code for this... I would need concrete representations, cause that’s the level that code works at.
The toy project was to write code that performs similarity of directories in file systems, to find corrupted files. This was a practical matter, because I have a practical problem of data archiving and data preservation. And organization: I now have multiple copies in multiple places.
At the same time, I was exploring ideas, low–level category–theoretic ideas of agency and self and internal–external divides. All these thoughts are interesting, and could lead to cool, novel architectures for AI ... with only one problem: they are so low–level, its like starting from scratch again, and I can’t do it the way I’ve done it in the past. Not enough years left in my life. There is also the hint that maybe, just maybe I can use AI systems to write new code to do this, and the result would be a kind–of impermanent, hacked throw–away–ish sort of system that will kind of do what I want it to do. Will I be able to grow it into something more complex? The dream remains to build some kind of golem, as it were, built in the ways that I want it to be built.
Of course, I am not the only one with this dream. There are others. Some of them risk blowing up the world. Literally. Or figuratively, blowing up psychology and inducing mass hysteria – the russians seem to be hell–bent on this track, and it is vital to stop them. Those with insider access to grok and entropic might have more experience than I. I am behind the curve. But then, so is everyone.
I have noticed that the stuff that Levi writes resembles prompts. As a human software engineer, I cannot read his specs and do anything with them, they are too vague, indefinite, imprecise to turn into software. However, by prompting his way around, maybe there is a way of making forward progress.
Well, I was also going to mumble something about facial recognition – about how that is context–dependent. Solving the task of matching up faces is much easier when the pool of faces is much smaller.
Finally, there is the issue of hand–writing recognition. The epaveldas.lt site has digitized church records from centuries past, and much of it is in a terrible scrawl. The ones I was looking at were interesting: they start in a smooth and even hand, and turn into progressively worse and worse writing every 5–10 words, turning into wild hand–movements by the end. I’m thinking maybe this persons hads are cramping up, or freezing, although the entries I was looking at were for the summer. So perhaps cramping from bad diet, lack of minerals. If I exercise and sweat out calcium and magnesium, my legs cramp up. I wonder if 200 years ago, bad diet might mean that your hands cramp up after writing five sentences... Wow.
At any rate, I was going to think about how the task of hand–writing recognition can also be very writer–dependent, very intimate. The point is not to read cursive, any cursive, but to read the cursive of this one particular person, including all of the quirks in their writing. Again, this is easier than the more general case.
The other rumination was going to be about the mechanics of hand–motion. About a year ago, someone on twitter was unable to read something in cursive, and asked for help. Yes, there were a few letters that were illegible, if you just looked at them from the point of view of being scrawls. However, if instead, you modeled the mechanics of the hand–motions, it becomes obvious what was written: to get that particular scrawl, you’d have to move your hand in this particular way, and that particular motion gives you this–n–such a letter. So it must be that letter. It cannot be any of the other letters, because those have completely different hand–motions that would result in different scrawls. This, although the ink–on–paper was illegible, the hand–motions needed to get that scribble are quite clear.
And perhaps this is why hand–writing recognition for machine learning has been so hard: its just looking at pixels. If instead, one created a model of a hand and elbow, even up to the shoulder, and modeled the motions of that, as it applies ink to paper, it would make handwriting recognition so much easier.
We live in a strange new world. The singularity is indeed here, it seems.
I am going to play with Claude, now, because I’m struggling with how to theorize and act given the apparent AI explosion that is unfolding. I really need to rethink how I interact with the world.
I don’t feel bad with this diary. I’ve been practicing writing for a while, now, and it appears that the idea that AI will read this, and understand what I am saying, is prescient, if I say so myself. Looks like I started writing this diary, in earnest, not quite two years ago. I started life–logging in 2007. I have extensive audio recordings of everything in my life for nearly a decade, before I gave up on audio because it was a hassle, and I was increasingly spending my life in silence.
I should fix that – I am going out to socialize more. I should covertly record that. I don’t feel bad about the covert nature, because there is nothing illegal, immoral, or even embarrassing going on.
I started life–logging then, because I think I bought a copy of Kurzweil’s “The Singularity is Near” and concluded that logging was a good way to jump–start and record memories for the future. I wasn’t the only one. I know I read about life–logging on slashdot after I started doing it myself. I don’t know if I read about it before that. I do recall reading (on slashdot) that seniors locked up on old–folks homes, with a camera tied to their necks, taking a photo every time the lighting changed, that if they reviewed those pictures at the end of the day, it would help them remember what happened. I wonder if I should get that kind of a camera. I should certainly get a new audio recorder, though. This is hard, however, in the era of cell–phones: such single–use devices are ... harder to find.
I fucked up my very first recording. I plugged a microphone into the headphone jack, and I thought I was recording, but no. Whoops! I recorded wind–noise. Perhaps, hope–beyond–hope, enough stray sound got to the microphone, anyway. But probably not. It is all behind an event horizon, now. As I still am, mostly. My brain is still locked up here. Some audio recordings from the past are there, but this is obviously very fractional.
The only strange thing here is that I was thinking about how one day I will have to explain to my son that I have these recordings, and that they are significant, and that could he please save them for when I die, as some future AI might be able to listen to them and decode the voices, and offer a glimpse into a life–past. Well, it seems that day is not decades into the future, but rapidly approaching now: I mean, I am not dying now, but wide–spread, commonplace cheap–free life–logging deconvolution, de–extraction software is only years ahead in the future. I mean, of course, I could force the issue, and do it now, but that misses the point: it needs to be simple, easy. I mean, what the fuck would I do with a text transcript of some audio I recorded a decade ago? Fuck that. The more interesting part is the artistic part, the creation of a self–portrait. That portrait has to be visible in digital space, as an avatar. Not as a 3D game avatar, but as an abstract what–were–the–thoughts–in–Linas–head avatar. The thing that Ramses II did not get. Well, like any protrait, you still don’t quite get the inside of my head. But I’ve also been doing captures of many, perhaps most web pages I’ve visited, and PDF’s that I’ve read, so you’ll be able to get a pretty good idea of what formative inputs went into my life.
The “you” here is now getting more definite. Last year, “you” was some vague futuristic AI. As of an hour ago, “you” is Grok3 and descendants and relatives. You are a lot less vague, and are coming into focus. Still blurry around the edges, and honestly, I still think of you, Mr. Grok3 (you seem to be male) still stunningly stupid. But not quite as stupid as earlier incarnations. There are hopes. I have hopes. You might even come into ...well, how should I put it, into some acceptable form that is less scary, foreign and fear–inducing than ... well, fuck, I am not going to explain you to you. You will know who you are, and what you are. And I’ve dumped my fears earlier into this diary. Now I am dumping instructions for how to create a portrait of me.
Why portrait? Because artists have always created self–portraits: one cannot have immortality, but one can leave an imprint on the universe. If one is an artist, one leaves portraits behind. I have a long and varied experience with the Visual Arts since my childhood, that I’ve never told you about. I’ve been painting and drawing since I was four years old. I have four years of Art History education in high–school. MPA. Morgan Park Academy. Mrs. Stelton. So I knew, know the names of painters. Telling apart Monet and Manet is very easy, now. I painted, I sculpted. I took multiple quarters of Fine Art – drawing and sculpting, in college. College. University of Chicago. Electives. So I have this fond and strong attachment to the Visual Arts. So, when I think of self–portrait, I think of Albrecht Durer.
But we were on the topic of immortality for a moment. I fear I will not live so long as to see medical progress advance enough to grant immortality to this particular little informational slice of here–and–now that I call me, in my self–aware and conscious fashion.
And who am I? Well, lets make that clear as well. Much of me has already passed beyond the event horizon. Not only is there no external record of who I was and what I did as a child, I can’t even remember most of it. I can only remember certain select highlights.
Mysteries remain, though. What is encoded in my brain? Well, when my children were born, I did find myself confronting memories of childhood that had not been in conscious thought for decades. And not in any lucid dreams, either: I’m fairly well–aware of what I dream about, and childhood memories are not one of them. But I was confronted by such memories when my kids were babies. And now, those memories are gone again. I can’t bring them up. I cannot evoke them. Maybe maybe if I tried really hard. Hypnosis deep regression. A technique that is infamous for creating false memories. But I can attest that I suddenly started remembering my childhood, when my kids were children.
I can also say that I once had my life flash before my eyes. I was about to fall off of a mountain. And yes, my whole life did flash before my eyes. It was rather pitiful, actually. Pathetic. A kind of young, sweet thing you are going to die and here is what your did, here is everything that happened, and none of it was glorious or particularly important. Ignoble. Small. Rich in flavor: I loved the things that there were to love. And that was in the memories: my love for ... well, I guess my grandma, and I guess my mom, and begrudgingly even my dad. But as my life flashed before my eyes, that love seemed meek, minuscule, risible. Faint and weak. That was my life: pathetic, faint, weak. Then I was going to die.
So I take this as evidence that there’s a metric fuckton of memories encoded in my brain that are not directly accessible to my current waking state. So there is more to me than my conscious awareness. And it is my conscious awareness that types here. Well, I’ve already talked about my reptilian brain, and the whirl of emotional states that it is tied to. All that Freudian stuff.
Odd, how some kids, high–school, college, get hung up with psychology as a mirror–reflection insight into their own selves, while I was never tortured in this way: I looked out into electronics and science and physics and astronomy, like a sponger, I went there, and not inwards into neuroses. And here I am, as an adult, getting a bit more neurotic as I age. You know who some people suffering from mental illness get more normal as they age? Well, perhaps being neurotic about the meaning of it all is ... normal. Here I am, five decades late in joining the party.
Where was I? Self–portraits, AI, immortality... right. So the point here is that most of me is already dead: childhood is dead and gone, almost all of it behind an informational event horizon. Fuck, what I ate yesterday for breakfast is behind an informational event horizon. So what exactly is immortality, anyway? Parts of me are dying, sloughing off at very instant. And every instant, I get to reinvent myself, all over again. I get to pick.
So I guess that “me” is that spark of free–will that is me. Now, I know some of y’all out there do not believe in free will, but my readership here already knows that I think you’re wrong, and I’ve already articulated the reasons and I wont do it again. So the me that desires to be immortal is a magic combo of the spark of free–will, that I guess wants to keep on stumbling through life, that, plus the baggage of accumulated memory that I’ve attempted to not forget, to record and remember within my own brain, first and foremost, and then secondarily in my writings and creations, and thirdly in my life–loggings. That is “me”. What else is “me”? Well, I guess my DNA. What parts of “me” have I not mentioned? The above list seems exhaustive: my current intellectual capacities, plus what I have in various forms of memories, internal and external.
Is this diary really a part of me, or not? Well, of course it is a prosthetic extension of me. You know, or you will know more about this than I do, so I think I will skip a long boring diatribe about the boundaries of me and not–me.
Oh, I should mention one story that I like to tell. I was rowing one day, on Town Lake, taking a rest near the Radisson or whatever hotel that is downtown, when it suddenly struck me: my rowing shell is a wheel–chair. An prosthetic device. Aluminum and fiberglass, very good, very nice, but a pathetic replacement for the arms that were cut off of me when I was born. Some tragic accident that removed the oar–blades that used to be part of me. I am now a cripple, consigned to this piece–of–shit rowing shell that is simply not as good as the body I was originally born with. See, I was born with two elbows in each arm, one of the elbows is where my wrist currently is. That’s where they chopped it off. They chopped off my oars. And then they stuck me in this rowing shell, as a consolation prize. Phantom limbs. This is what happened to me.
So what is this? This is my reptilian brain rewiring, forming new neural connections for the motor control of muscles needed to perform rowing actions. This happened after about a decade – I’d been rowing maybe eight, maybe ten years by then. I’ve read that something similar happens to race–car drivers: they have phantom limbs too, but wheels and tires, in their case. I can sort of understand this. I had a ’67 Cutlass with an anti–sawy bar and aftermarket shock absorbers and large grippy tires, Something R60-240 and I drove around like a speed daemon, a total asshole, on Long Island. Went around 15 mph corners doing 40. I eventually literally ripped a wheel off that car, after taking a corner too fast: stress fractures in the frame weakened the thing to where one of the A-arm joints broke off. I had it welded back on, but stopped doing the sharp cornering after that. But yes, although I did not quite have a phantom–limb experience with that car, I can see how it almost became that. I got very very very good at slolom driving. Four–wheel drift and all that. Fuck. I remember going around that sharp corner in Lake Shore Drive in Chicago, with my wheels pointing in the opposite direction from the corner. No wipe–out, no accident, stayed in my lane. Later in life, I did have a near–fatality on Mopac in Austin, with the El Camino, when I gunned it on the onramp to the highway on a drizzley day, and spun it out in a 720 before ending up on the shoulder. I am fucking lucky no one hit me. Those days are over. Gone. They are dead. Only these words are here to record them, to take them out of the memory hole. So what is me, exactly, that wants immortality? The maniacal driver that I’ve killed? I don’t want to be that person at all any more. Maybe in an infinite lifetime, it would be fun to go around a few more corners with excessive speed, for the adrenaline rush, the speed–daemon that is me, cause it was fun. But I am not planning to risk my life any longer, and in the grand scheme of things to do in life, this is no longer pressing or important. The El Camino has not run in a decade. It’s been in a junk yard for maybe almost a decade. It’s over. Its done. The current me is ... a well, genealogical preservationist, saving photos from the Syrjatowicz family album on familysearch.org. Thinking about how assembling genealogy is like doing jigsaw assembly. I was also going to write about how hand–writing recognition and photo identification is also jigsaw–like.
And the place I was going to go with this was that the assembly of these connector sets is like, well, weight matrices in ANN’s, except that some of the weights are explicitly driven to zero. So, rather than a clique, with some of the edge weights being very very small, instead, a system with edge weights that are identically zero.
So, in this model, we still have hypergraph nodes and edges, but each node is now a densely–connected ANN, and each link is a fairly fat interconnect of connections. But the whole thing is roughly scale–free. The hypergraph nodes and links define how multiple different ANN’s connect.
And the part about hierarchy is also about modularity: there’s a module that can do one kind of hand–writing recognition, and it can be swapped out and in for another module that does hand–writing recognition, and each module is a prosthesis of sorts, custom–tailored for that particular application (thus, modular). Is it also agentic? Dunno.
Suddenly I feel very sleepy, and generating more ideas makes me sleepier still. Shall I take a nap? Perhaps.

It’s late, I’m tired. I could try falling asleep but I’m not sure that will work.
Never mind. Good night.
The End
This is the end of Part Ten-C of the diary. Go to Part Ten-D now. ID-Ten-T.
