DARPA, the military’s mad science division, is also a master of PR, we all cheer them on, even though they may be building a robot army that one day hunts us down. But the robots have become a cliche, of course. DARPA was actually founded to “prevent technological surprises” of any kind after the Soviets launched Sputnik in 1957. As a result, it also supports beneficial projects only peripherally related to defense, like Ebola research, brain-controlled prosthetics and space exploration.
