Well, as bad as it is to say, porn really drove technological innovation in computers in the 80's and 90's. But besides that and 3d games, this thing has applications. This is one of those thins, like drones, and 3D printing, that people will find a lot of good uses for, and it is cheap enough that some ground breaking apps will be written in basements.
Porn built the internet. Absolute truth. It drove the need for increased computer power and bandwidth.
