CNN style holograms (though hopefully more realistic) are coming to the US military. Using a process called “quantum ghost imaging” they hope to create realistic, self-aware virtual soldiers that can be actually put into battle. The exact science behind quantum ghost imaging is a bit mind boggling, and not quite perfected, yet (though very close).
Beyond holographic soldiers, the army is pursuing equally sci-fi to reality tech, such as erasing and implanting memories(!), electronic telepathy and regenerating body parts. There’s hope that some of the more practical (like limb regeneration) innovations will eventually be used to help everyday people.
