I'm not dismissing the benefit of face-to-face. But there's some % of material in college that you learn by reading the textbook, and using the computer -- especially in tech disciplines. These aspects of learning feel like they would be pandemic-proof. For the self-motivated, I can see where they don't miss a beat under the changed environment. And that's also why with higher-ed, the bang-to-buck ratio isn't always high. And YouTube just works.
