In his most recent book, "Love and Sex With Robots," Levy says human relationships with androids, humanoids, fembots, malebots, intelligent machines, Stepford wives, or any other name they may adopt, are "inevitable." He arrives at this conclusion after studying historical relationships between people and their machines, news in the field of robotics, and not to mention the booming sex toy industry pulsing with vibrators and life-size dolls.
