Is anybody solving really cool problems anymore?
tallanvor: Of course people are working on a lot of these (and other) interesting technologies.  In Tokyo, you can see some models of self driving cars and robots that Toyota has come up with.  You'd better believe there are a lot of companies working on furthering 3D technology and immersion - everyone from Sony and Nintendo to Microsoft and Google.Why don't you hear more about this?  Simple, the companies that can afford to spend money on this sort of thing like to keep a lot of the work quiet until they determine whether or not they can commercialize it.
