The future should have been perfect. Microscopic robots known as nans could repair any damage to your body, keep you young by resetting your cellular clocks, and allow you to download upgrades like intelligence, muscle strength, and eyesight. You were supposed to be able to have anything you wanted with a simple thought, to be able to fly without the aid of a machine, to be able to live forever.
