Why would regular glasses be an uphill battle? People optionally wearing glasses for fashion has been a thing forever. Sunglasses are a status symbol.All of this. I've owned 3 HMDs and will always aim to have one for driving and flight sims. VR is amazingly Immersive and unlike anything else when it's done well. But the friction to use it and the isolation one experiences in it confine it to niche status. Even as just a pair of glasses it would be fighting an uphill battle.
People even wear fake prescription glasses for the look.
I can easily see glassholes making a return once the tech is actually there. If not for the functionality, just to flaunt, the same way people flaunt their iPhones, smartwatches, airpods, Ray Bans, etc.
