Some colleges are going to try in-person learning. They will also have an online-learning option. Some colleges aren't even trying. My friend's daughter's college, University of Seattle, finally gave up this week. Online only. If the dominoes start toppling, others may yet join them.
But "completely online" is a recipe for a different disaster. Imagine paying $30,000 to $60,000 for your kid to sit in their bedroom taking classes on Zoom. Imagine every class and vocation that requires physical tools and interaction. How much value do you put on the college experience itself? Many colleges have to raise tuition because they are bleeding cash all over the place. My daughter and her friends are all planning gap years and hiatuses, and both private and public universities may not survive the exodus.
