The central concept in this which was not mentioned was gamification. Education needs to be gamified, ie. every small step about it needs to be quantified, the student needs to receive instant feedback, the "game designer/educator" needs to see the data and improve the game.

Somewhere along the line the education system came to be about competition, who scores the highest gets to brag he's the cleverest and somehow superior. Instead, it should be about gaining competency in a fun way. Doesn't matter whether students reach it at 15 or 25 or older. (separate issue, but the core competency everyone in society should have nowadays is the ability to program in python).
