Science fiction has a funny habit of becoming science fact after enough time has passed. The wide-eyed wonder of children sitting cross-legged in front of the TV eventually becomes inspiration for incredible feats of engineering, or the means of our own destruction. The latest example of this phenomenon is a new, powered up exoskeleton the U.S. Army is testing, per Scout. There are tons of examples of this sort of thing in science fiction. It usually involves military personnel enhancing their combat capabilities with some manner of armor or exoskeleton.
