One day, robots will attempt to take over the world. Look no further than this video of a robot playing Guitar Hero as evidence. Today, it’s video games, tomorrow it will be machine guns. Okay, the army already has machine gun wielding robots. Also, I’m not sure why robots would need guns in the first place, since they could easily crush your skull, but the idea of gun toting robots just sounds cool, and hey, maybe they don’t want to have to chase you?
