Yeah I'm just not convinced the ones in the movie are any more complex than our current ones, just more well harnessed, pun intended, as the harness and tooling around the LLM dictates a lot of its abilities, for example [0]. I don't believe the ones in the movie have any actual form of consciousness as humans would understand it. And as far as (simulacra of) internal models, seems like LLMs have that today too, as an emergent property [1].
