Japanese scientists claim to have developed a sex doll that is amazingly lifelike. Advertisements for the dolls in Japan say anybody who buys one will never want a real girlfriend again.

That’s probably an exaggeration, but the thing is, just as robot workers are getting better while human workers stay the same, so robot women are getting better all the time, too. And smarter: Siri’s inventors are working on a new artificial intelligence program called Viv that will do “anything you ask.” Put that together with the fancy sex dolls, and you’ve got a true fembot.

We’ve already been warned about what comes next by Matt Groening’s Futurama series, in which an episode warned of humanity’s extinction as illustrated by a boy who was more interested in making out with his “Marilyn Monroebot” than in school, work or dating. The moral was don’t date robots, lest society lose its reason for existence: “All civilization was just an effort to impress the opposite sex. And sometimes the same sex.” And, of course, sex with robots doesn’t produce children, eventually causing the entire species to die out.

Which leads me to think: A hostile artificial intelligence such as SkyNet would be better off making super sexy robots than Terminators.
