Their view seems to me 'computational.' They are associating thinking with computation and think if you just get nanotechnological about it, you can achieve consciousness and thinking. Seems to me, this is similar to thinking that the universe is just a computer simulation of 'physics' equations on the some gigantic computer somewhere higher than 'us(the anthropic principle).' I personally don't believe that the universe is governed by physics equations churning at every infinitesemal point of the universe. And, because the brain is part of the universe, I don't see how the brain can just be a computational device. I bring these ideas up for criticism and comments.
