...where do I think this guy looses it?
Well when he departs from the computational argument and gets into mind debating and qualia.
I mean is not that we don't have to assume mind plays a part which we do. But is that his kind of argument starts pushing into dualism when he goes "qualia"... or worse, monism idealism and solipsism...minds do not create themselves nor do they have free will. I rather speak of 2 computational systems minds and world interacting whith each other but without special mind properties. I stick with abstract computational approach and leave it at that. Hope that clarifies my pov to you guys. Have a nice day ya all! (Mobile phone)
