I'm sure I'm not the only one who felt like my schooling was mostly a giant waste of my time and energy.
I was waaaay ahead in subjects I liked, because those things I learned myself out of innate interest. Rather than the system accommodating and encouraging being ahead, in those subjects I was held back and forced to sit through material I already knew, because "in year x we learn this and in year y we learn that". Don't get ahead. Zero agency.
In other subjects that didn't interest me, I was forced to sit through stuff only to forget everything I "learned" soon after.
It really begs the question, what's the point? And while I'm no genius at anything, surely a system like this will kill many, many actual geniuses, just like the article says.
