The risks of autonomous military robots, spacetime warp drive, body heat as power source …
“The deployment of the first armed battlefield robots in Iraq is the latest step on a dangerous path – we are sleepwalking into a brave new world where robots decide who, where and when to kill.” Ethical minefield, folks.
“If you had a device that could manipulate the expansion of spacetime, would you have the makings of a stardrive?”
