Leaving this weird, rather Valley-specific, even YC-specific, navel-gazing definition of "founder" aside, universities should do what they promise to do for their students. And if possible for way, way, way less money.
He seems quite out of touch with the level of economic hardship involved in being a student; a huge number of students already work a couple of jobs and are navigating small businesses, especially here in the UK where he apparently now lives. They aren't going to have enough "free time" to play with a "project" even if a bit more is made available by loosening the curriculum.
If any change is necessary it should be that every university student has access to actual education and ongoing (post-graduation) support to start a real, not hypothetical business, rather than leaving them in this "ripe for YC picking" state where they have "done projects" but don't really have any awareness of business.
If students leave university immediately able to run their own businesses, understand how to bootstrap, be closer to self-funding etc., that leaves them in a stronger position than if they can show they have done stuff but need an external startup meat grinder to get them anywhere. Especially since the job market is being screwed the world over.
But YC doesn't want its people to be that independent. It wants them persuadable, overconfident and desperate to sign up to space camp.
