The second reason I think it’s a bad idea is if the robot-with-a-gun is not remotely controlled by a human but ‘autonomous’. Of course there are serious ethical and legal problems with this, like who is responsible if the robot makes a mistake and shoots the wrong person. But I won’t go into those here. Instead I’ll explain the basic technical problem which is – in a nutshell – that robot’s are way too stupid to be given the autonomy to make the decision about what to shoot and when. Would you trust a robot with the intelligence of an ant, with a gun? I know I wouldn’t. I’m not sure I would even trust a robot with the intelligence of a chimpanzee […] with a gun. […] Personally I would like to see international laws passed that prohibit the use of robots with guns (a robot arms limitation treaty). source Unverified
