Good movie but highly disturbing. They are A.I. and fighting against humans. Not extraterrestrial life. Elon musk has spoken of this stating that A.I. is far more dangerous than nukes.
There is more to this movie than one may actually see. They make us out to be the villains and A.I. is just innocent. Remember Terminator? Machines taking over the world. Yeah this is no different. Time to start paying attention people. A.I. is the technology taking over. Most are just too blind too see what's really happening
