I disagree with your point is. Personally, I think If using a robot instead of human work, it will just increase the number of unemployed people has caused the robber. Or there may be a stealth kill at all that is the fact that may occur in the future and stock, have no idea of their own, of course. To be input into the program. If one robot may have problems or disruptions, we can not control it. I maintain that like a dummy that was better than humans. The man is stronger than the robot, but it is an idea rather than a robot.
