Exactly, tons of different technologies are POSSIBLE. But it's a matter of what's economically feasible (what consumers will pay for, etc.)
We could have had Web TV in 1995 if it was really economically feasible... but no on figured out the business model. And it looks like it still hasn't been figured out, although Google is trying again with Google TV.
That said, I think Kurzweil, while grading himself overgenerously, did a pretty good job, and no one else is making these kinds of predictions. I actually did the same thing back in 2009, since I am a Kurzweil fan. It's a little interesting how many things came true in 2010 -- he cheated by a year but it helped him a lot!
