Interesting stuff. Still reviewing the video and can see why tedster's wheels are turning...
As press and visually focused as the folks at Google seem to be getting, I'm starting to wonder if they plan to buy any broadcast networks or media companies in the near future.
It would seem a logical extension to their online ad network, providing a ready source for their media ads that go beyond web based advertising.
Now they can tell you everything you would want to know about yourself, identify you in any pictures and finally knowing all the demo data, be able to tell you what you might want to buy before you actually are aware you want to buy it.
With your medical records online, they could even set up some nifty public Google retina scanners and to allow them to present ads on street level billboards targeted to your specific interests.
Perhaps the vision of our future really is one as shown in Minority Report. After all, a few years from now, you really won't mind having that GPS/Mediscan tracking chip implanted... it won't hurt a bit.
