Google's Ray Kurzweil predicts the future

Today in class we read an article about Ray Kurzweil and what he predicts will happen in the future and what had already happened. It was an interesting article and the one that I found most interesting was that in the year 2023 there might be full-immersion in virtual reality. Basically a brief summary would be that nanobots or some kind of small device will stimulate your capillaries and brain so that you can feel like you are actually in the game. I think this would be pretty cool.
