I'm not saying the content is bad. I'm saying the expectation to get paid for content is bad. Grant is still going to do 3blue1brown even if he doesn't get paid because he cares about math and about teaching math. If he quit his day job it would force him to make new videos he wasn't 100% passionate about; it would force him to change his content to suit the algorithm.
