It's the future. The technology already exists to make that stuff reality, but it's not mainstream, not production ready, and certainly not affordable, yet. I remember a few years back when scientists invented the first completely transparent computer chip (my idea was contact lenses with a TV screen inside them, rofl).
I'm not against new technology and everything, but this stuff is really scary. I'm looking at our society right now and I see how Facebook, Twitter, smart phones, etc. are all affecting our way of life, and I'm just uneasy about all of it. I just can't see it ending well. 50 years from now the stuff in this video will be mainstream, and I really hope I'm not alive when it is.
