A.I. expert David Levy says a human will marry a robot by 2050

Human-robot relationships are a running theme in pop culture, from the cylons of Battlestar Galactica to Spike Jonze's film Her and last year's hit show Westworld. But that kind of scenario might not be science fiction much longer. Romance between humans and machines is already nearing the realm of the possible. This year, the California company Abyss Creations plans to start selling a new generation of high-tech sex robots -- dolls that can actually speak and respond to touch. And according to artificial intelligence expert Dr. David Levy, in a few generations, we won't just be having sex with robots, we'll be marrying them.
