I'm sure there was pockets of people who thought 3D TV was the greatest thing ever, and look how far that technology has come. Alexa and Siri were once upon a time going to be the greatest things ever, until everyone realized how very meh the experience was in practice. Smart watches were similarly going to change the world and have since largely pivoted to being niche products for health nuts.
BTW, I'm not saying you're absolutely wrong! I just don't think there's any reason to believe you're right, either, and a lot of reasons you might not be, including sky-high costs, practical technology limitations, the lack of killer applications, social barriers to adoption (see: Google Glass), etc.
Man, that family must be doing very well for themselves to afford at least two full VR rigs.
Look, if VR kit becomes reasonably priced for average consumers (which also means GPU prices have to come down), maybe I could buy into your touching vision, here.
But we've got a long way to go before this kind of gear is remotely affordable enough to result in the kind of mass adoption required to realize these purported benefits.
As for Zuck, if he sees opportunity here, all the more reason for me to hope it never succeeds...
AR will be a niche product constrained primarily to industrial applications.
There, we've both made our blind predictions, now we get to see who's right!
