From Popular Mechanics:
A soldier wears a skullcap that stimulates his brain to make him learn skills faster, or reads his thoughts as a way to control a drone. Another is plugged into a Tron-like “active cyber defense system,” in which she mentally teams up with computer systems “to successfully multitask during complex military missions.”
The Pentagon is already researching these seemingly sci-fi concepts. The basics of brain-machine interfaces are being developed—just watch the videos of patients moving prosthetic limbs with their minds. The Defense Department is examining newly scientific tools, like genetic engineering, brain chemistry, and shrinking robotics, for even more dramatic enhancements.
But the real trick may not be granting superpowers, but rather making sure those effects are temporary.
