Social Bots. It’s been a rough couple of years for Facebook, but if all the humans leave, perhaps it can develop some social robots to friend each other and hang out. Turns out Facebook is busy developing a collection of robot behaviors, ones it can deploy on real six-legged and arm robots. This bot research is not, in fact, about building better robots. Instead, the company hopes to use what it’s learned about AI system and apply it to some of the learning algorithms it currently deploys for humans on Facebook.
