Working prototypes trump all theory.
I heard all silicon valley gurus stating they were "bearish on VR, bullish on "AR". This proliferated as a mantra throughout the industry. I thought they were wrong then, and believed the opposite - because I had a working VR headset that was awesome, but had only heard somewhat meh things about existing AR prototypes.
Until great AR hardware comes out, I'm still sticking with the same opinion.
It's old but it was one of the first hits

How teens communicate might have changed but I'm guessing the relative amounts show girls still use it more.
I firmly believe that at some point those same people will embrace full eye AR (not phone AR) as a preferred or common way to communicate over all current methods. Further, I believe that once it's possible for them to do it easily without cumbersome equipment that AR will become mainstream.
It's clearly years out but the fact that I can carry a tiny and relatively light computer on my wrist with display (a smart watch) suggests it might not be that far off to have stylish glasses with similar tech at a price people will pay for once the applications make it clear they want it.
If you asked in 2007 how many non-techies wanted a PDA the answer would likely have been close to 0. Now the answer is close to 100% of them carrying one at all times. I think AR will be no different. What has to happen is they need to go from the bulky Apple Newton level tech of today to something light and useful.
