He says good founders learn actual stuff at college and get good at something, without any ambition to make it profitable initially.

It's... not? He's describing how to cultivate founders in university. I'm saying that it's not what a university should be focused on.

A startup is not a technical project, it's an organisational endeavour. They don't live or die by the product alone, but by the market demand, organisational robustness and a little bit of luck.
