robots in warfare? (Score 1)

isn't anyone worried about what the increasing sophistication in robotics will mean for warfare? i am not talking about machines taking over but something much more plausible - robots going around shooting bullets killing people at the orders of people thousands of miles away? to an extent this is already happening, if one defines 'robot' loosely. But with the introduction of mobile machines capable of visual recognition this becomes much more scary. the cited article seems to completely ignore this.
