Query: The future is bearign down on us.

Mr. Kurzweil has a dramatic view of the near future that makes most science fiction look timid. He takes 500 pages to carefully document how genetic, nano, and robot technologies will soon lead us to first, biological immortality, and then to the creation of a digital super-intelligence that will eventually expand throughout the visible Universe. Kurzweil builds the case that the Integration of human minds with the digital mind (The Singularity) will be possible by 2045.At first blush, the thesis of this book appears far-fetched and the time-line absurd. Mr Kurzweil, arguably one of the greatest intellects of our time, carefully builds a complete defense of his predictions and responds to criticisms. This is required reading for anyone who wants to think seriously about the future of mankind and the planet.
