I’ve spent the past 12 years in online teaching, and I’ve come to love it. But what I’m hearing from instructors — via social media, email, and old-fashioned conversations — is growing despair. They are exhausted by their efforts to teach class in real time via Zoom and other videoconference formats, and so are their students. Many academics seem to think they’re doomed to this mentally draining existence until the end of the semester, or beyond.
