The robot apocalypse is nigh. Boston Dynamics’ robots are doing backflips and opening doors for their friends. Oh, and these 7-foot-long robot arms can lift 500 pounds each, which means they could theoretically crush, like, six humans at once. The robot apocalypse is also laughable. Watch a robot attempt a task it hasn’t been explicitly trained to do, and it’ll fall flat on its face or just give up and catch on fire.
