While Americans debate human evolution, the pace of evolution itself is about to explode, says acientist and futurist Ray Kurzweil. In this century, he and others say, humans will reach what they call "the Singularity": the moment when man and machine, humans and their technology, become one.
Kurzweil foresees human intelligence vastly outstripped by computer intelligence and then wholly merged with that intelligence in this century, within a few decades. And then: profound, revolutionary upheaval on this planet and far beyond. Kurzweil welcomes the onslaught. Skeptics look on in doubt and dread.
Hear a conversation with Ray Kruzweil on evolution's big bang, the merger of humans and machines.
