Fundamentally, VR just isn't very social unless all participants have the proper hardware already. Sure, you can have a TV output to see what the headset user is seeing, but the TV-viewing experience is still very different from the headset experience. Not to mention, it looks really jerky and jarring as a non-interactive user.

I feel like VR is a technology that has no idea where it fits into the world. It's cool, but why should anyone care about it before they've put up the money to buy into the ecosystem? It's not like a TV which is an easily shared experience.
