I see computers of the future as being similar to modern helmet-mounted heads-up displays used by our military pilots, only far more advanced and powerful in a computational sense. But instead of being integrated into a helmet, they’ll be integrated into an ordinary pair of glasses or sunglasses, or maybe even implanted somewhere in the human body... brain, eye, etc.
I can see advertisers, gov't drones, and hackers all salivating at that possibility. Imagine accidentally downloading a virus directly into your brain, or having your body's motor controls seized by the state.
I don't want to live in that future.
