In a way this is exactly what they said about GUI in 1983. People looked at the early products like Apple Lisa and Xerox Star, and said: “Serious businesses aren’t going to be spending thousands of dollars per user on gimmicks like the mouse and high-resolution graphics. Office tasks don’t need that.” — And they were right, but only within the narrow field of what office work on computers was like in 1983. WordPerfect and 1-2-3 didn’t need the GUI. Excel and the web browser did.

I’m not saying VR/AR is going to turn out the same way, but it seems at least possible that new affordances will create new kinds of applications again.
