It's an interesting question of how to qualify your words when you talk about how widespread the tests are. I'm sure fewer than half the people I know have had COVID tests (versus tests everyone gets), which makes the tests per person metric potentially a little deceptive. I think it's a fair point that the possibility of constant testing tied to access to employment or entertainment could change our culture.

I think this is much less of a problem than you make it out to be. Having a lot of information, and having the information gradually improve in quality, is a good thing. The media's inundation of people with the information and the insanely stupid public dialogue surrounding it all is... less good.
Nevertheless, to the original point, I think all the analogies a person could draw between today and the dynamics of the AIDS epidemic and those years of uncertainty, discrimination and death make what's happening today seem less psychologically traumatic by comparison. Maybe it's less clear because we were already dealing with Very Stupid Times before COVID 19 came along.
