South Korea has placed robots with machine guns along the North Korean border. The most interesting/troubling quote:

 “Techwin spokesman Huh Kwang-hak was quoted as saying by Stars and Stripes: ‘But these robots have automatic surveillance, which doesn’t leave room for anything resembling human laziness. They also won’t have any fear (of) enemy attackers on the front lines.'”

 Yes, can’t leave that sort of thing up to the meatbags, can we?
