Artificial intelligence (AI) expert Levy describes how early experiments in logic, games and speech led to others about thought, creativity, learning and translation. He discusses how AI devices play games, recognize visual input and speech, communicate, conduct sports, chauffeur, conduct search and rescue, perform surgery and help with medical diagnoses, work around the house and approach being humanoid. He concludes with well-grounded speculation about such advances as the DNA computer, nano-machines, models and applications of emotion, robot consciousness, and the development of robot rights and ethics.
