I think VR enthusiats like myself are just going to have to accept that some people just will never be interested in VR, and worse, they're going to be actively hostile towards it if they see it as threatening the way they currently enjoy playing games. I know it's frustrating that every single VR thread always devolves into "it's just a fad and I want it to go away" basically, but we'll have to ignore it.
Let them think that. It's just going to be that much enjoyable when they are wrong and miserable because VR is everywhere and is a thriving success down the line. And heck maybe they're right and VR will be the next video game fad to come and go, but at least we didn't waste our time in threads arguing about something we had no interest in, in the first place.
Outside of the Gear VR, google VR and few other devices, we aren't even at consumer level product yet. There just needs to be one killer app for the medium and they will go chase it.
