The Singularity Is Near: When Humans Transcend Biology

For over 3 a long time, Ray Kurzweil has been probably the most revered and provocative advocates of the function of know-how in our destiny. In his vintage The Age of non secular Machines, he argued that desktops might quickly rival the total diversity of human intelligence at its top. Now he examines your next step during this inexorable evolutionary technique: the union of human and computing device, during which the data and talents embedded in our brains might be mixed with the drastically larger means, velocity, and knowledge-sharing skill of our creations.
