This quote "I sometimes feel that the creative minds who make games have done about as much as is possible in two dimensions. It’s hard to imagine how the current crop of games, for example, could be more finely tuned to deliver that particular kind of entertainment." isn't particular inspiring coming from a Chief Futurist. I can imagine a ton of 2D (or text based, for that matter) games that haven't been attempted let alone perfected. I also feel like I play new novel 2D games all the time.

I say this as someone that is excited about VR, AR and would love to see whatever Magic Leap is cooking up, and is a huge Neal Stephenson fan.
