Sure, but we need to base our predictions of the future on our experience of existing similar technologies to have any credbility. For example, if I predicted that phones the size of a coin are the future, you could meaningfully say "in my experience, bigger phones are actually more sought after, so I don't believe your prediction".
if I predicted that phones the size of a coin are the future My phone is on my wrist currently (Apple watch), I left my iphone at home. To me your prediction would have been correct (for now). If you insist on basing your predictions on existing experiences, think of your sunglasses: light, comfortable, stylish. I predict that 10-20 years from now your sunglasses will offer great AR/VR experience, most likely through…
Your Apple Watch is still dependent on your iPhone. You're also unlikely to be browsing the web, watching YouTube, or browsing social media on your watch, and these have been the biggest factors for smartphone adoption by far - so I don't think such a prediction works. We can also see that the market for smartwatches is dwarfed by the market for phones, and this trend shows no sign of reversing.

The problem with a glasses form factor is that it fundamentally can't create enough contrast for a good quality image, especially not for VR - that requires blocking out most light coming into the eye, which no additive technology can do. I do believe that some equivalent of a smartwatch could work very nicely in a glasses form-factor (i.e. a device that acts as an accessory to your main computing devices, for small specialized tasks).
I still don't see any plausible way it could replace phones or laptops/tablets with any technology visible on the horizon. So I'm not saying AR/VR won't have a place or even be wildly successful - just that I don't believe they will ever be "the future of computing" in any reasonable sense, say like the smartphone was to the PC.
