For the last 17 years, the Japanese robotics company FANUC has been operating a very special factory. At this facility, robots build other robots—50 of them each day. The building is “lights out,” meaning it operates without human intervention. It can do so for a month at a time.
If this sounds like the beginning of a Philip K. Dick short story, it is. (Thankfully, though, FANUC employees get along far better with their robots than Dick’s protagonists do.)
