I apologize, I read an implication in that wasn't warranted.
I think what led me to that was the idea that older generations have already seen infrastructure crises, so only younger ones would be learning something new. But I guess that's not really the case, is it? Has there been a major infrastructure crisis in the last ~100 years?
No need to apologize, it was a reasonable assumption. As you say though, I don't think living memory (at least not much) extends to that kind of crisis. Most living memory no longer recalls a lot of important lessons that we culturally believe we've learned "forever".
