SF is down to 3.9 new cases per 100,000 per day from a peak of 53.9, it is already going to be silly to be wearing masks while walking around in public away from crowds. You were never going to catch coronavirus from walking past someone who had it (which is one reason why the protests were not significant sources of spread). I seriously doubt that masks outside in SF serve any purpose right now in SF.
And the rate is still declining, at some point it'll be under 1 in 100,000 which would be 3,300 cases per day across the united states. I doubt we can achieve a lot better than that given that there's 883 million outpatient visits per year (CDC stats) with 1% of them for influenza like illness in the summertime which is a 24,000/day minimum rate. Having 10% of that background be coronavirus is probably the lowest it'll go.
There's always going to be some level of coronavirus spread, but if you're vaccinated and the level of spread is where its at now in SF then you need to be more worried about getting T-boned by an Escalade (particularly the way people blow red lights in SF).
So the people in this thread are correct. The time to unwind is pretty much now. At the same time they're unreasonable to expect everyone to just instantly drop everything because they're failing to account for the way people behave (and particularly when the strategy has been successful for the past ~15 months).
