gollark: Would you accept something as "truly thinking" if it appeared entirely identical to a human over a text chat?
gollark: That seems somewhat silly. It takes humans a lot of training to control complex real-world machinery, and that's with lots of intuition about the physical world in general already extant.
gollark: Interesting.
gollark: I know roughly how the training process works. I just dispute that it can't lead to "intelligence" of some kind.
gollark: And possibly about uses for it.
