It's only a matter of time.
Hide ya kids, hide ya wife! According to the Terminator franchise, at 8:11 PM today (April 19th), the military-designed artificial intelligence system called Skynet will become self-aware and turn against its creators (read: us). If that doesnt have you shaking in your boots our world will be overwhelmed by a legion of killer robots in approximately 48 hours - a time known as Judgment Day. I, for one, welcome our new robot overloads. Check out the video below if you doubt the existential risk posed by this android Armageddon. Watch Skynet exhaust the worlds nuclear stockpiles to the sounds of sweet symphonies.
