The book builds on the ideas introduced in Kurzweil’s previous books, The Age of Intelligent Machines (1990) and The Age of Spiritual Machines (1999). This time, however, Kurzweil embraces the term the Singularity, which was popularized by Vernor Vinge in his 1993 essay “The Coming Technological Singularity” more than a decade earlier.
Kurzweil describes his law of accelerating returns which predicts an exponential increase in technologies like computers, genetics, nanotechnology, robotics and artificial intelligence. Once the Singularity has been reached, Kurzweil says that machine intelligence will be infinitely more powerful than all human intelligence combined. Afterwards he predicts intelligence will radiate outward from the planet until it saturates the universe. The Singularity is also the point at which machines intelligence and humans would merge.
