I think Turing was wrong because he was uncomfortable with ambiguity, and the Turing Test basically is a way to avoid philosophical argument, but it is ultimately a philosophical argument anyway. Plenty of computer scientists have followed in Turing's footsteps, terrified of ambiguity, relying on a kind of cheap functionalism as a salve. You can claim to just be doing science, but inevitably you dip into metaphysics and deny you are doing so. That's this thread in a nutshell. "I only believe what I can prove, but I suspect that if I can't prove it then I don't have to worry about it." My argument, is that you have to worry about it anyway.
