Almost all sci-fi movies are just test beds for technologies they already have or they are working on. They give the ideas to the writers to incorporate into their scripts......then sit back and watch the public's reactions. This determines when the technology is released. If its a positive reaction, its released sooner. If its negative, they know the public needs more brainwashing......and when they are ready, its released then. We have a LOT of really scary stuff coming our way in the form of robots.
