<p>Apart from the exhaustion of context switching, I believe there is a internal signal that gauges how "fast" things are happening in your life. Stress responses are triggered whenever things are going too fast (as if you were driving in a narrow road at too much speed) and it feels like there is danger since you intuit that a small mistake is gonna have big consequences.<p>Some people thrive in more stressful situations, because they don't get as aroused in calmness, but everybody has a threshold velocity at which discomfort starts, higher or lower. AI puts us closer to that threshold, for sure.</p>

<p>Agree. But sometimes there is no "root cause", the brain is still a mystery. If you had been depressed even when you knew there was nothing to worry about, you would see it differently, because then you deduce that the black cloud is produced within.<p>Chemistry trumps psychology. Good enough chemistry enables cognitive treatments. But to fix the wrong chemistry you need chemistry.</p>

<p>Yeah, but the xz algorithm is also not counted in the bytes... Here the "program" is the LLM, much like your brain remembers things by coding them compressed and then reconstructs them. It is a different type of compression: compression by "understanding", which requires the whole corpus of possible inputs in some representation. The comparison is not fair to classical algorithms yet that's how you can compress a lot more (given a particular language): by having a model of it.</p>

<p>In my case I fully grasp what such a future could be, but I don't think we are on the path to that, I believe people are too optimistic, i.e. they just believe instead of being truly skeptical.<p>From where I look at it, LLMs are flawed in many ways, and people who see progress as inevitable do not have a mental model of the foundation of those systems to be able to extrapolate. Also, people do not know any other forms of AI or have though hard about this stuff on their own.<p>The most problematic things are:<p>1) LLMs are probabilistic and a continuous function, forced by gradient descent. (Just having a "temperature" seems so crazy to me.) We need to merge symbolic and discrete forms of AI. Hallucinations are the elephant in the room. They should not be put under the rug. They should just not be there in the first place! If we try to cover them with a layer of varnish, the cost will be very large in the long run (it already is: step-by-step reasoning, mixture of experts, RAG, etc. are all varnish, in my opinion)<p>2) Even if generalization seems ok, I think it is still really far from where it should be, since humans need exponentially less data and generalize to concepts way more abstract than AI systems. This is related to HASA and ISA relations. Current AI systems do not have any of that. Hierarchy is supposed to be the depth of the network, but it is a guess at best.<p>3) We are just putting layer upon layer of complexity instead of simplifying. It is the victory of the complexifiers and it is motivated by the rush to win the race. However, I am not so sure that, even if the goal seems so close now, we are going to reach it. What are we gonna do? Keep adding another order of magnitude of compute on top of the last one to move forward? That's the bubble that I see. I think that that is not solving AI at all. And I'm almost sure that a much better way of doing AI is possible, but we have fallen into a bad attractor just because Ilya was very determined.<p>We need new models, way simpler, symbolic and continuous at the same time (i.e. symbolic that simulate continuous), non-gradient descent learning (just store stuff like a database), HAS-A hierarchies to attend to different levels of structure, IS-A taxonomies as a way to generalize deeply, etc, etc, etc.<p>Even if we make progress by brute forcing it with resources, there is so much work to simplify and find new ideas that I still don't understand why people are so optimistic.</p>

<p>Very snappy, I like the animations very much (they keep changing, you had fun!). I tried signing in with Google and it didn't work (blank screen). But I've played a lot with these games and I've made my own, and yours is very addictive because feels quick and the feedback is clear. Also I found the jump from the first wave (short words) to the second (very long words), a little too big. I would put an intermediate one in between.</p>

<p>You hit a very important point, the discomfort that orderly people experience (I am that kind of person). I believe that to be innate.<p>At the same time, a disorganized person is still more effective in an organized environment, but probably he hasn't realized this by himself because he doesn't have the internal drive to be organized in the first place.<p>You could say being organized is Nature's way of setting us up for success in complex and very demanding situations.</p>
