more Ray Kurzweil... MUST WATCH (all four parts).  from VBS (which is an incredible site of its own):

Ray Kurzweil tells us about his vision of the Singuarlity—a point around 2045 when computers will acquire full-blown artificial intelligence and technology will infuse itself with biology. His theories have all sorts of supporters, detractors, and critics, but do you even remember what life was like before three-year-olds had cell phones and you actually had to remember facts instead of relying on the internet? That was only 10 years ago. If Kurzweil is right, we'll have supercomputers more powerful than every human brain on the planet combined within a few decades.

Despite being perceived as an extreme optimist, Kurzweil is the first to admit that this technology could very quickly bring an end to the world as we know it. Stuff like gray goo is a concern, but a biological terrorist attack could happen tomorrow that is based on the very same type of technology he touts as the harbingers of the unimaginable future. He believes we'll exist in a permanent virtual/"real"-reality hybrid.
