After reading the comments here, I think a key issue isn't so much humanity losing knowledge, as it is "locals" for some definition losing it. Manufacturing is alive and well in many places, somebody knows how to build or fix your lawnmower, it's just that the middle class has lost that knowledge, etc. I believe there continues to be more "repatriation" of knowledge - look at semiconductor manufacturing, but it's less a question of it ever being lost. I'd also say that "preparedness" is generally something nobody is working on. Despite all the shit that happened with Covid, I don't feel like we're even slightly better prepared for an actual lethal pandemic, like with double digit death rates for example. It's not clear we've changed anything other than some political jockeying. Another example is earthquake/ tsunami preparedness. Everyone knows the west coast is going to be destroyed, we just ignore it because its "boring" and nobody wants to think about it
