There's a lot to be said about the value of online classes.  I've done something like 400 of them since 2020 although I now only do one session per week online, and the rest are face to face. During lockdown, there were about 70 people per class which, right from the start, made watching everyone on my screen impossible; I therefore ran the class like a kind of one-man show - it became a daily (sometimes twice daily) TED talk.
