In the 'Terminator' universe, Skynet was built as a Global Digital Defense Network, an artificial intelligence that could command all computerized military hardware. The military installed Skynet because it would remove human error and guarantee faster, more efficient reaction time. It also guaranteed nuclear armageddon when it gained self-awareness and forced the surviving humans into slave labor. So that part was bad. But the first thing, the network command of all computerized hardware, that was a good thing, right?
Hey, guess what, everybody! That first thing is starting to happen, and its name is RoboEarth! And just in case you're worried, that name refers to uniting all the robots on Earth in a peaceful "learning experience" and does not conjure up images of a robot revolution at all.
