I saw a video of a humanoid robot vacuuming somebody's kitchen and thought it was a Sci-fi Movie Clip. It wasn't. Real company, real houses, thirty bucks an hour. The part I missed was sitting in section 2 of their own terms of service: the robot is not autonomous, a person is controlling it. Then I found out the fastest robot in the Beijing half-marathon lost for the same reason. That's how this started.
