It's a plotline straight out of the Terminator films: a highly evolved computer program controlling U.S. government weaponry goes rogue, defies its human masters, and sets out to exterminate all of humanity. Think it's just fiction? While humankind has yet to suffer a Judgment Day-style nuclear holocaust, the U.S. Air Force battled its own sentient SkyNet adversary this week when an MQ-9 Reaper combat drone broke free from human control during a mission over Afghanistan. The unmanned aerial vehicle, charmingly classified as a "hunter-killer," had to be shot down by a manned aircraft before it continued on its merry way – headed, according to an Air Force press release, "on a course that would depart Afghanistan airspace."
Now, I'm no weaponry expert, but I'm certain of one thing: that's not supposed to happen. Like, ever. Sure, technology goes awry from time to time, but only in the movies, right? Maybe not. Below, we pick five fictional pieces of movie science with actual real-world counterparts, and the terrifying implications that they bring for the future of humanity.
