So Roger Penrose, not content with the now-seemingly-attainable quantum computing, speculates there is an even more magical quantum gravity computing, which brains just happen to use, that makes them special, that Turing machines can't compute?
The man just really hates the idea of AI, doesn't he?
That's nothing new for Penrose, he wrote about it in Emperor's New Mind. His whole argument is based on noncomputability, and he points out in the book that ordinary quantum computers can't do the noncomputable.
And of course if he were right and we did figure out the physics of it, there'd be nothing to prevent us from building hardware that uses the same physics.
