Remember that cool Will Smith movie where everyone just had to have an iPhone and once everyone had one, the iPhone's central computer turned on humanity? Each iPhone was programmed to keep its owner safe at any cost? But humans have a way of creating danger on their own and so the iPhones, to keep with their mission, kept all of their owners under lockdown in their own homes so that they could not be of harm to themselves?
Oh, that was iRobot? OK. My bad. Carry on.
