Another non-sci-fi story that sounds like it is: The Predator
. "[The United States] has produced a weapon like no other this country has ever used: the Predator, an unmanned reconnaissance drone." The Simpsons predicted this years ago:
The wars of the future will not be fought on the battlefield or at sea. They will be fought in space, or possibly on top of a very tall mountain. In either case, most of the actual fighting will be done by small robots. And as you go forth today remember always your duty is clear: To build and maintain those robots. Thank you.

But the Predator isn't funny. Once they have computers completely controlling those things, machines will finally be able take over the world. I've seen it happen on Star Trek time and again. Have we learned nothing from TV?
