when will the singularity occur?
There will be no distinction, post-Singularity, between human and machine or between physical and virtual. Kurzweil estimates that the Singularity will happen in the year 2045. But that's not all. The Singularity, which is to say a humanity which has merged with technology, will turn its own intelligence into pure energy and saturate the universe at, or beyond, the speed of light. In the aftermath of the Singularity, intelligence, derived from its biological origins in human brains an its technological origins in human ingenuity, will begin to saturate the matter and energy in its midst.
