Kurzweil later conceded that radically extending human life could lead to a "deep ennui" if nothing else changed, but he believes we will grow smarter and vastly improve our quality of life. Nanobots, if we let them swim around our brain capillaries, will boost our brainpower, he said, as they chatter with our biological neurons over a wireless local network and the Internet, creating a hybrid form of super-intelligence.
"This scenario will enable us to expand our mental faculties through these massively distributed neural implants with no surgery required," he added.
