Here’s a scary thought. By 2050, we will be having sex with robots, even marrying them. That’s the prediction of chess master turned artificial-intelligence expert David Levy.

In his new book, Love and Sex With Robots: The Evolution of Human-Robot Relationships, Levy writes technology is advancing so fast that one day there will be robots so lifelike we won’t be able to tell them from real people.

In an interview with the Houston Chronicle, Levy points out there are some upsides to these “sexbots.” Especially for people who are physically unattractive, anti-social and/or have problems finding love. “They’re lonely; they’re miserable,” according to Levy. “I think society will be a much better place when they have an alternative that satisfies them without doing any harm to other people.”

Not a bad argument. Maybe the world would be a better place because everyone would be making love not war. So instead of sending in the Marines, we could unleash the “love machines.”
