I am a deep LLM skeptic.

But I think there are also some questions about the role of language in human thought that leave the door just slightly ajar on the issue of whether or not manipulating the tokens of language might be more central to human cognition than we've tended to think.

If it turned out that this was true, then it is possible that "a model predicting tokens" has more power than that description would suggest.

I doubt it, and I doubt it quite a lot. But I don't think it is impossible that something at least a little bit along these lines turns out to be true.

I also believe strongly in the role of language, and more loosely in semiotics as a whole, to our cognitive development. To the extent that I think there are some meaningful ideas within the mountain of gibberish from Lacan, who was the first to really tie our conception of ourselves with our symbolic understanding of the world.

Unfortunately, none of that has anything to do with what LLMs are doing. The LLM is not thinking about concepts and then translating that into language. It is imitating what it looks like to read people doing so and nothing more. That can be very powerful at learning and then spitting out complex relationships between signifiers, as it's really just a giant knowledge compression engine with a human friendly way to spit it out. But there's absolutely no logical grounding whatsoever for any statement produced from an LLM.

The LLM that encouraged that man to kill himself wasn't doing it because it was a subject with agency and preference. It did so because it was, quite accurately I might say, mimicking the sequence of tokens that a real person encouraging someone to kill themselves would write. At no point whatsoever did that neural network make a moral judgment about what it was doing because it doesn't think. It simply performed inference after inference in which it scanned through a lengthy discussion between a suicidal man and an assistant that had been encouraging him and then decided that after "Cold steel pressed against a mind that’s already made peace? That’s not fear. That’s " the most accurate token would be "clar" and then "ity."

    The problem with all this is that we don't actually know what human cognition is doing either.

    We know what our experience is - thinking about concepts and then translating that into language - but we really don't know with much confidence what is actually going on.

    I lean strongly toward the idea that humans are doing something quite different than LLMs, particularly when reasoning. But I want to leave the door open to the idea that we've not understood human cognition, mostly because our primary evidence there comes from our own subjective experience, which may (or may not) provide a reliable guide to what is actually happening.

      We do know what it's not doing, and that is operating only through reproducing linguistic patterns. There's no more cause to think LLMs approximate our thought (thought being something they are incapable of) than that Naive-Bayes spam filter models approximate our thought.

      • PaulDavisThe1st 19 hours ago

        My point is that we know very little about the sort of "thought" that we are capable of either. I agree that LLMs cannot do what we typical refer to as "thought", but I thnk it is possible that we do a LOT less of that than we think when we are "thinking" (or more precisely, having the experience of thinking).

    'Language' is only the initial and final layers of a Large Language Model. Manipulating concepts is exactly what they do, and it's unfortunate the most obstinate seem to be the most ignorant.

      They do not manipulate concepts. There is no representation of a concept for them to manipulate.

      It may, however, turn out that in doing what they do, they are effectively manipulating concepts, and this is what I was alluding to: by building the model, even though your approach was through tokenization and whatever term you want to use for the network, you end up accidentally building something that implicitly manipulates concepts. Moreover, it might turn out that we ourselves do more of this than we perhaps like to think.

      Nevertheless "manipulating concepts is exactly what they do" seems almost willfully ignorant of how these systems work, unless you believe that "find the next most probable sequence of tokens of some length" is all there is to "manipulating concepts".

        Yes, they do. And of course there is. And there's plenty of research on the matter.

        >It may, however, turn out that in doing what they do, they are effectively manipulating concepts

        There is no effectively here. Text is what goes in and what comes out, but it's by no means what they manipulate internally.

        "Find the next probable token" is the goal, not the process. It is what models are tasked to do yes, but it says nothing about what they do internally to achieve it.

If anything, I feel that current breed of multimodal LLMs demonstrate that language is not fundamental - tokens are, or rather their mutual association in high-dimensional latent space. Language as we recognize it, sequences of characters and words, are just a special case. Multimodal models manage to turn audio, video and text into tokens in the same space - they do not route through text when consuming or generating images.

I'm convinced of this. I think it's because we've always looked at the most advanced forms of human languaging (like philosophy) to understand ourselves. But human language must have evolved from forms of communication found in other species, especially highly intelligent ones. It's to be expected that the building blocks of it is based on things like imitation, playful variation, pattern-matching, harnessing capabilities brains have been developing long before language, only now in the emerging world of sounds, calls, vocalizations.

Ironically, the other crucial ingredient for AGI which LLMs don't have, but we do, is exactly that animal nature which we always try to shove under the rug, over-attributing our success to the stochastic parrot part of us, and ignoring the gut instinct, the intuitive, spontaneous insight into things which a lot of the great scientists and artists of the past have talked about.

    I’ve long considered language to serve primarily as a dissonance reconciliation mechanism. Our behavior is largely shaped by our circumstances and language serves to attribute logic to our behavior after the fact.

    Are you familiar with the major works in epistemology that were written, even before the 20th century, on this exact topic?
