If we don’t have a few effective COVID vaccines and/or COVID treatments in the next couple of years, this may be the norm for higher education and professional schools.
I doubt that this will ever become the norm. Pandemics end either with a vaccine or the population just stops the panic mode and learns to live with it, similar to the seasonal flu. This just doesn’t have the mortality rate to permanently adjust the norm. Humans are social beings, and we all know communications are far more than just words and a zoom picture. JMHO.
^ No psychologist here, but my impression of both academia and the court system is that both institutions are packed with oldish risk-averse types who probably won’t be opting to return to an “in-person” format anytime soon. And of course for that age group, Covid is more deadly than the flu (for which there is a vaccine). I can easily see this continuing for awhile. Who tells the judge how to run his/her court? 
@JBStillFlying You get me checking:

Oh boy, all three Senior Judges were born before the end of WW2. The Honorable Judge William Bauer was born in 1926. Judge Joe Flaum is 84 and still active. Judge Frank Easterbrook, who was already famous for his work in Law And Economics when I was in GSB in the 1980’s, is still active at age of 72. I would say none of them would want any in person court hearings anytime soon 
Just a hunch but the longer this pandemic drags on the more apparent will be remote as the way forward. And what about the next pandemic? It’s not like this is a one-time thing. The world is hit every few years. Whipping out your mask when you have to meet in person and converting some of your activity to remote to protect the vulnerable (which next time might be the young people) sure as heck beats another harsh lock-down.
