Yeah that's a common result of forced learning by lets be polite mediocre folks. Utter hate of the whole topic for easily 2 decades too. Then finding slowly my own personal way back to them, despite school.

If anything, current (and this is valid globally) school system is not designed at excellence at its core, its about raising an army of obedient but not too stupid citizens. And its not missed expectation, just look at what type of work they expect to fill in. Don't expect massive changes unless society changes itself.

Some narrow excellence is not what our society at large values, those few that made it through made it despite their environment.
