Sure, that's totally reasonable! It all depends on context - I think I'm safe to assume another human is more similar to me than an ant, but that doesn't mean all humans are roughly equivalent in experience. Even more important, then, that we can't assume a machine or an algorithm has developed similar experiences to us simply because they seem to act similarly on the surface.

I'm on the opposite side of the fence as you, I don't think or suspect that any LLMs or ML in general have developed self-awareness. That comes with the same big caveat that its just what I suspect though, and could be totally wrong.
