The Age of Spiritual Machines

The Age Of Spiritual Machines is a book by futurist Ray Kurzweil about the future course of humanity, particularly relating to the development of artificial intelligence.

Originally published in 1999, the book makes rather bold predictions that machines with human-like intelligence will be available from affordable computing devices within a couple of decades, revolutionising most aspects of life, and that eventually humanity and its machinery will become one and the same.
