That is, once a device is useful or otherwise desirable enough... Issues like awkwardness or microefficiencies fade.
I think the issue is that there's not enough to do in vr/ar. If we had a vr game of thrones, then everyone would be in vr watching it. If ar made some job much better, everyone doing that job would use one.
The modern platform paradigm means all the speculative, creative investment is on the platform itself. "Creators" make the content. Well... The prizes for creating "content" are mediocre.
A breakthrough filmmaker will have to make the VR's first blockbuster for the art... and so will their financiers. You can raise some money to make ar software, but the unicorn potential is slim compared to a platform play... the big bucks aren't available for such.
