Kurzweil tells about the evolution of the neocortex in mammals and how this part of the brain has helped to expand our way of thinking and reasoning beyond the point that our earlier ancestors would have been capable of. Now the neocortex is about to evolve again and he theorizes over what this new growth will bring about.
And so, over the next few decades, we’re going to do it again. We’re going to again expand our neocortex, only this time we won’t be limited by a fixed architecture of enclosure. It’ll be expanded without limit. That additional quantity will again be the enabling factor for another qualitative leap in culture and technology.
