Not content with creating Terminator-like soldiers such as Atlas, and the Avatar mind-meld program that allows human soldiers to control their robotic equivalents from afar, the US Army is now working on a human-on-a-chip. These HoCs will ostensibly be used to safely test new chemical weapons, and to explore possible treatments for exposure to chemical weapons, but long-term it's easy to imagine that these chips will be used as the basis for sentient, human-like robot soldiers -- much like the humanoid Cylon "skinjobs" in Battlestar Galactica.
