I’m talking purely from my impression of humanity and nothing else – i don’t see anything changing when these barn doors open. People will have an emotional need to put this fear laden time behind them and continuing a fight with a microbe that may or may not still be a threat won’t cut it for most people.
The high risk people will probably live more fearfully, but most people who probably already had it and moved on will be chomping at the bit to pretend life goes on. And i believe it will. Our insides might have matured but on a societal scale i would be shocked if anything looks different.
