Maybe we do. I think it's a human tendency at large to ascribe pattern or intelligence or spirit where there is only noise. If we can't even prove our own intelligence, doesn't that reinforce the idea that we're in no position to claim intelligence has emerged by running our own intellectual output through a fixed set of weights, the training of which we also designed? At best, any such intelligence would be entirely self-refential and exposed to the question of whether we ourselves are intelligent. If your position is that we are not, then there's no way an LLM could be.
