It gets pretty complicated but the implications of what AR is doing are quite significant. For those not familiar with Layar, it is a platform that allows anyone to build an AR app. You use your mobile phone's camera to view the world and since your phone knows where you are and what you are looking at.The implications are profound. One of the most interesting apps that someone produced was a virtual tee-shirt shop. It was placed in the 20 most expensive shopping streets in the world, selling t-shirts. Stop and think about that for a minute. He built a virtual shop where a real one already existed. His shop was accessible via a mobile phone, the real one was accessible through, well, being real. That means that real space and virtual space can be owned by different people. There will be lawyers."
Some programming languages manage to absorb change, but withstand progress.
