I don't like reading transcripts of interviews. I would much rather the author took the time to digest the material and present a summary. That said, this statement caught my eye:

"It’s been a very intense period partly because I was teaching a lot. And there was the shift to Zoom, which created more work because you’re trying to prepare differently and do your lectures differently. It’s obviously a surreal experience overall."

So why didn't Rogoff refuse to teach that way? Probably because cancelling his classes would have obligated Harvard to refund the tuition. So he went along with the school and provided a degraded learning experience to his students, all so Harvard didn't have to dip into its massive endowment and do the right thing.
