According to futurist Ray Kurzweil human civilisation will be unavoidably transformed in the year 2045 by an event that he call The Singularity. He suggests that exponential technological development will lead to the inevitable rise of artificial intelligence (A.I.). Such advanced technology may make humanity insignificant.

Kurzweil says that technologies are double-edged swords and envisions the possibility that an artificial intelligence might decide to put an end to humanity simply because it surpasses human intelligence. Kurzweil does have faith in mankind, however. He suggests that people are wise to accept that technological progress is unavoidable and that such acceptance will make the process of transition easier.

Kurzweil has personal reasons to hope for the coming of The Singularity, because he wants his life to be extended by it. Kurzweil envisions that future medical advances could invent tiny computerised machines, or nanobots, which operate inside the body to enhance the immune system. In addition, he believes that future technology might be able to resurrect his deceased father.

Looking at the state of current technological advances in many fields such as medicine, navigation and communication, Kurzweil's visions may not be unbelievable. The critical issue, however, is whether genuine artificial intelligence can ever be truly realised. Kurzweil suggests that critics of his theories, who believe that the human brain is too complex to duplicate, are underestimating what the exponential growth in technology can eventually accomplish.
