Over the past 40 years I've become aware of a LOT of people who had difficulty staying engaged in self-paced learning sessions, especially pre-recorded. Without the dynamics -- questions and interactions -- that other students can pose (or you can pose), it's tough to maintain your attention for a solid 50 or 90 minutes. Not that all courses must be in-person, but I'd there to be a mix, with more in-person opportunities for course material that needs Q&A and interaction and examples, like courses heavy in math or theory, or recitation sections.
