This serene confidence is not shared by neuroscientists like Vilayanur S. Ramachandran, who discussed future brains with Dr. Kurzweil at the festival. It might be possible to create a thinking, empathetic machine, Dr. Ramachandran said, but it might prove too difficult to reverse-engineer the brain's circuitry because it evolved so haphazardly. 'My colleague Francis Crick used to say that God is a hacker, not an engineer,' Dr. Ramachandran said. 'You can do reverse engineering, but you can't do reverse hacking.'"
