Well it's clear to me that if we want to assert humans == intelligent in all cases, then the definition must be loose enough that no healthy human can fail it, even the dumbest ones. The fact that we are even talking about this means that there is clearly a large scale of inteligence, from mosquitos dodging a bug zapper to Von Neumann making the rest of us look like drooling idiots. It's pretty clear that the average LLM is lower than the average human on this scale, but it may also be above the dumbest one. And that scares people because we won't improve further and LLMs definitely will. Or LMMs will anyway, LLMs by themselves are a bit of a dead end with only text.
