Back on topic, I actually think "we" collectively learned some things, and many perhaps think some things about COVID that are not warranted. I keep reading these mRNA vaccines are being tested against other agents, which could end up being a good thing. I think "we" mostly understand now that lockdowns might flatten the curve a bit but area under the curve remains the same. I could see a one week or so lock down in the future, but probably not much longer than that (if the plague were much much more lethal folks would panic and lock themselves down). We saw how the "news media" is not very adept or honest.
Maybe some other things, dunno, I'm slightly surprised today how little impact COVID has on our lives, for which I am thankful.
