This volume discusses the implications of teaching our computers and robots to think. The authors, a paleontologist and an artificial intelligence guru, team up to present some of the sociological, theological, and scientific issues that we will face in the 21st century. Over 150 years ago Darwin realized that evolutionary change is the driving force in our universe. The text considers how Darwin failed to appreciate how fundamentally the evolution of science and technology will change not only our world, but our very minds - and how soon it may happen.
