Right. Oculus Rift has been developed in the US, and seeing all the companies that have followed the trend of VR (Valve, Sony, HTC, HP), I guess this could be an example of a revolutionary tech. Tesla while not revolutionary (electric vehicles as an idea and some demo has been around for a long time) has been the first to democratized the vehicle to the masses. Now every car makers are making an electric model. That's revolutionary.

A lot of example from China I'm seeing are good looking and impressing demo (Xiaomi Alpha Mix) but are impractical for general consumers.
