I'm kidding, but seriously, this is something we would have called "out there" scifi 20 years ago:

Ronald Arkin, a professor of computer science at Georgia Tech, is in the first stages of developing an "ethical governor," a package of software and hardware that tells robots when and what to fire. His book on the subject, "Governing Lethal Behavior in Autonomous Robots," comes out this month.

I hope he doesn't start using T- as part of his version numbers :)
