Interesting to see this as my Grandmother who was a museum curator for decades had a comment on this with the exact opposite thoughts. When the pandemic faded 100 years ago almost overnight people quit wearing masks. When the Civil War ended many photos were destroyed as people simply wanted to forget what happened and get back to normal (this is what made her job quite difficult in finding these documents/slides).
The general public has an amazing ability to forget tragedy, and I'd expect this will be the same. Even now we cheer the fact that new hospitalizations is only at 52,000 a day, still a stunning number. Even with masks, I'd say it was not until July that it became completely prevalent throughout the United States. I remember going to the grocery store in May last year and receiving comments for wearing one in line with maybe only 30% of customers actually wearing one.
I'm interested to see what happens with all this going forward. From a societal perspective I'd say this is easily the most turbulent time since 2001-2002
