Your average peasant for millenia didn't need to understand Information security to avoid getting phished, didn't need to understand compounding interest for things like loans and saving for retirement (they'd just have kids and pray enough of them survive), didn't need to have some kind of mental model for the hordes of algorithms deployed against us for the express purpose of taking all of our available attention (a resource that people before a couple decades ago had so much excess of that boredom was a serious concern) for the express purpose of selling it to people who want to extract any dollar you may have access to, did not need to understand spreadsheets(!), etc etc etc etc
Like, being productive in modern society is complicated. That's what education is for.
