Since Google and Microsoft have basically photography and build 3 models of the entire planet, you can now do something pretty amazing with your photos - zoom, look around, look around the corners and see the stuff you didn't photograph that day. In other words, you can locate your the subject of you photo in the vast online database of millions of other photos and recreate the surrounding. If you can dream it, you can make it happen.

Sometimes I sit stupified by this kind of progress. Its a solution to a problem I never thought about, a dream I never knew I had, made real...its almost frightening...and this is just one of millions of innovations being demoed everyday. How useful is it? I don't think that question even matters. The point is that 10 years from know you will be in a totally different world where every thing you see and touch is endowed with a level of technology enhancement that makes it magical. Every photo you take (if you even have to take photos anymore - maybe they will just be auto-recordings of you line-of sight that you can browse through at will) will be endowed with a magical quality. No knowledge out of reach...and the journey man started in the garden of Eden, that quest that began with the first bite of knowledge, that first lesson learned, will be at an end. We will not know everything, but everything we know will be known by everybody. Our species and the machines that support us will act as a single, conscious entity. With no one and everyone at the helm...
