My wife Margaret and I sold our house to Sir Roger Penrose and his wife... Talking to Roger, I found we both agreed that AI, as they call it, is not going to be achieved by present-day machines."Artificial Intelligence" - that makes it sound simple, but what you're really talking about is artificial consciousness, AC. And I don't think there's any way we can achieve artificial consciousness, at least until we've understood the sources of our own consciousness. I believe consciousness is a mind/body creation, literally interwoven with the body and the body's support systems. Well, you don't get that sort of thing with a robot.
