Human or Robot? It's Hard to Tell

This 2010 video of a robot mimicking its inventor is going viral, but not because people are excited about technological advancement . . . they're simply creeped out. The frighteningly realistic being looks more like a human doing a robot impression than vice versa!

The Japanese robot is a real invention — and in the five years since this video was shot, humanoid robot technology has only improved. While there's no denying that this robot's mannerisms are unsettling, her its existence suggests some pretty incredible possibilities. Will lifelike bots begin to man desks, answer phones, and run errands in the near future? Only time will tell! Now try not to have nightmares, because we promise — this is actually cool, even if it's also totally weird.
