Gizmodo ran an article today about robots fighting wars for us, and i only have one argument against it. And it isn't even a argument so much as a title of a movie.

RoboCop proved that without the human element robots are just mindless killing machines.

UPDATE: And what about Terminator, Terminator 2 and Terminator 3? Not to Mention Robocop 2, 3, and 4?
