If that’s true, mastering language is basically orthogonal to being conscious (as you’d maybe expect, GPT-2 was pretty good at language, but had a relatively tiny amount of “neurons”).
The same is arguably true for world modeling: a math textbook has a very complex and coherent model of a world, and is, probably, unconscious.
Then the question is: what reason do we have to assume that these models have some form of consciousness?
