A galaxy far, far away?

Recently, I have started realizing that we have already (or nearly) reached the future as viewed from many years ago. Technologies that are already being developed or even now implemented into the real world are multi-touch computer screens, virtual reality, uniquely-engineered substances, holograms, and even flying cars. Robots, too, are continually being updated and become more and more advanced every year. The only thing that leaves almost every person lacking these amazing products of science is cost, as well a scarce need for most of them..
