What concrete changes would I make in schools? The idea that you need to take a whole class to learn some topic is absurd. Whatever you’ve learned is probably going to be obsolete. A class is to spur your interest, to expose you to a new role model, a new professor, to a new set of students. We should have way more classes which are way shorter. It should be much more about learning, more about variety, give up the myth that you’re teaching people how to master some topic; you’re not! You want to inspire them; it’s much more about persuasion, soft skills.
