On a tangential note, I wouldn't trust college or formal education with this task. This knowledge is much too important to allow it to be degraded into just another class to score a passing grade on. At least so I have gathered from my experience with formal education at all levels in my country; maybe things are better at the Ivies or MIT or top international universities in general, but it's a shame for society if one has to get to that percentile to have the full toolbox to think about the world around oneself.
Given this, how much knowledge acquisition should you leave to college? As a current college student I've been struggling with how much knowledge I should pick up on my own vs how much to get via courses. I've mainly focused on satisfying requirements with my courses while self-studying math/programming on my own, but I realize that this might not be the best use of resources.
I was looking at a discussion of what should be in a college curriculum, and as such discussions seem to go, there was a big list of things everyone should study, and some political claims about what's being offered but shouldn't be.
Instead, what do you wish you'd studied in college? What do you wish other people had studied in college? On the latter, do you think everyone should have studied it, or do you just wish more people knew about it? Approximately what percentage of people?
Of course, this doesn't have to be limited to college. People could learn the same things earlier or later.
