> the same fallacy as claiming that crows can't be black because they have DNA of a bird.

What fallacy is that? I’m a fan of logical fallacies and never heard that claim before nor am I finding any reference with a quick search.

It doesn't have a name, but I have repeatedly noticed arguments of the form "X cannot have Y, because <explains in detail the mechanism that makes X have Y>". I wanna call it "fallacy of reduction" maybe: the idea that because a trait can be explained with a process, that this proves the trait absent.

(Ie. in this case, "LLMs cannot think, because they just predict tokens." Yes, inasmuch as they think, they do so by predicting tokens. You have to actually show why predicting tokens is insufficient to produce thought.)

It's much simpler than that. X is in B therefore X is not in A is what being said, and this statement simply doesn't make sense unless you have a separate proof that A and B don't intersect.

Good catch. No such fallacy exists. Contextually, the implied reasoning (though faulty) relies on the fallacy of denying the antecedent. The mons ponus - if A then B - does NOT imply not A then not B. So if you see B, that doesn't mean A any more than not seeing A means not B. It's the difference between a necessary and sufficient condition - A is a sufficient condition for B, but the mons ponus alone is not sufficient for determining whether either A or B is a necessary condition of the other.

I think s/he meant swans instead (in ref. to Popperian epistemology).

Not sure though, the point s/he is making isn't really clear to me as well

I was thinking of the black swan fallacy as well. But it doesn’t really support their argument, so I remained confused.
