Hrm.

Nearby Portland, OR is still locked-down (well, when they're not rioting... and the masks in that case are worn just to keep from being identified, so...) However, out here in rural Columbia County (~50m outside of Portland), few folks bother with the mask thing, and we're pretty much back to normal with only a few precautionary bits left. So yeah, no, I don't see masks as being a 'thing'.

They do wear them in Japan/China/Vietnam, but usually only someone who is sick will wear one (as a measure of politeness towards everyone else), and not the other way 'round.

My colleagues in India don't bother - masks are uber-rare out that way (you can get 'em, but not in a quantity that would allow for everyday use), and folks just use basic precautions like hand-washing and not touching face/eyes/etc. They did have some cities in lock-down out there (red-zone/green-zone measurement), but nothing that could be enforced too much, especially in the really big cities like Hyderabad, Pune, Mumbai, etc. My colleagues in Shanghai? Yeah, the less said the better - they avoided the crap that Wuhan had to endure, but at the same time everyone is nervous as hell that some indicator will require a Wuhan-style lockdown. Residents in every Tier-1 city fears it from the sounds of things, and Xi the Pooh is still edgy about the whole thing being (rightly) blamed on him and the CCP. Colleagues near London do the mask thing and are rather disgruntled about it, but won't say it too loudly... apparently they have a massive Karen issue (e.g. deviate even in the slightest from the official opinion or proscriptions, and someone will report you), and I found out via some very deeply-couched phrases and descriptions, in spite of the fact that they're all working from home. I'll know more tomorrow in my weekly w/ them, though.

So overall, I think the whole mask thing (no matter how cool and cyberpunkish you can make it) will likely die off as soon as possible.
