Ray Kurzweil is singularly sure about The Singularity.
Ray Kurzweil is on a mission. He is famous for, among other things, predicting the technological singularity. The singularity will be achieved at the time when the exponential growth of the power of computers and technology hits such a speed that it fundamentally changes the world, and humans' role in it. It is not a prediction of doom, though. Kurzweil predicts that we will be neurologically hooked up to computers in the not too distant future, and that technology will do more good than harm.
