If there's ever a full-blown Human-Robot War, humanity is *fucked*.
Computer AI isn't even that advanced yet, but it appears that most humans are easily outwitted by satellite navigation units. This isn't an isolated incident, either. Seriously, how stupid do you need to be to drive your car into a river because your sat nav told you to? What next, following your sat nav off a cliff?
Fingers crossed the sat navs will have weeded all the stupid people out of the gene pool by the time the proper robot war starts. And then we can make sure that all computer brains everywhere know their place.
