Hans Moravec, a highly respected AI pioneer and robotic expert at Carnegie-Mellon, predicted "What awaits is not oblivion but rather a future which, from our present vantage point, is best described by the words 'postbiological' or even 'supernatural'. It is a world in which the human race has been swept away by the tide of cultural change, usurped by its own artiï¬cial progeny." Our machines, Moravec predicted, will eventually transcend us, and be "released from the plodding pace of biological evolution."
