David Levy, a British artificial intelligence researcher and international chess master, defended yesterday his Ph.D. thesis at the University of Maastricht in the Netherlands. The name of his thesis is "Intimate Relationships with Artificial Partners" and the University announced it under the name "Love and Sex with Robots." Levy says that trends in robotics and artificial intelligence will, 'within a few decades, result in robots that are so humanlike in their appearance and functionality, in their personality, and in their expression of emotions, that many people will be falling in love with them, having sex with them, and even marrying them.' Will it really happen? Are you ready for this?
