Valve Nanobots will be released. Nanobots crawl into the brain and couple directly to sensory-motor neurons. They simulate virtual worlds that can be experienced with all senses in better-than-real fidelity. Decoupling the motor system allows to get the feeling to really move in the virtual world without moving the real body. Which in turn is moved and controlled by the Nanobots in the meantime. Doing some payed work. Valve takes 60% of the money the body earns while the mind is hanging out in games like Half Life 3 Infinity. Of course the player gets ingame credits in return.
