I’m a bit of a latecomer to the Singularity concept. As I understand it, the singularity occurs when technological evolution is able to reproduce human intelligence, likely by simulating a human brain. It must happen, but when? Kurzweil gives a date of 2045 and gives a strong justification. My favorite part is right after that when he explains that, even if his estimate of the computing power required is off by a factor of a billion, that’s only 15 years in the exponential worlds of computation and storage. It’s coming, just wait.
