Heard that FPS like games can be used to treat lazy eyes, they put a blindfold down on the good one so the eye muscles have to strengthen on the bad one.
Besides that video games and browsing the web supposedly rewire the brain to more reflexive, though less capable of focusing on a single stream of thought. Kind of a throwback to what early humans behaved like. So I guess they can be developed to a brainwashing robot-making device, with some R&D.
