Mask wearing was common in some Asian countries at certain times of the year even before this so it doesn't necessarily need to end at all. It all comes down to what level of hygeine you want to pursue.
No lockdowns are going to happen, but I expect to be masking up for at least another 6 months. Not a big deal, definitely better than it was last August, that’s for sure.
I see in New York's case that there's been a big rise in cases but barely a blip in deaths, as opposed to both rising in step in Texas, I'm guessing largely due to vaccination rate. So I expect this winter will be a lot better.
In some countries at least it might become normalized the same way it has in say Japan or Singapore with a history of respiratory disease, the UK does not have the same aversion to public health measures as the US.
