Either the LLM is the most efficient way to generate text, or there's some magic algorithm out there that evolution stumbled upon a million years ago that we haven't even managed to see a hint that it exists. In which case, you'd be right, this is a fallacy.
Or, brainmeat can't do it better or more efficiently, and either uses the same techniques or something even worse. The latter seems unlikely, humans still do pretty well at generating text (gold standard, even).
> it's better to look at the way generative AI fails than the way it succeeds: when it makes mistakes in text or images, the mistakes are very much not the kind of mistakes that humans make, because the process behind the scenes is very different.
But are you looking at "mistakes" that are just little faux pas, or the ones where people with dementia, bizarre brain damage, or blipped out on hallucinogens incorrectly compute the next word? The former offer little insight. Poor taste in word choice, lack of eloquency, vulgar inclinations are what they amount to.
> but it seems unlikely we've learned to write by subconsciously arranging all the words we've encountered into multidimensional vector space and performing vector math operations to arrive at the next word
You think I meant that someone learns to do that at 2 years old, rather than that the brain has already evolved with the ability to do vector math operations or some true equivalent? I'm not talking about some pop psych level "subconscious" thing, but an actual honest to god neurological level faculty.
> but we reason about concepts and
Wander into Walmart next time, close your eyes briefly and extend your psychic powers out to the whole building, and tell me if you truly believe, deep down in your heart, that the humans in that store are reasoning about concepts even once a week. That many, if not most, reason about concepts even once a month. I dare you, just go some place like that, soak it all in.
Human reason exists, from time to time, here and there. But most human behavior can be adequately simulated without any reason at all.
