I will say, my wife and I both volunteered to teach online for a full year during the pandemic, which means we both got to work from home 3 or 4 days a week (we had to teach from empty classrooms in our schools the other days, when we had recess duty responsibilities). 

My wife taught a virtual kindergarten class, and having observed her, how she did it, and what she did, I sincerely think she should have been hired to instruct other teachers on how to teach kindergarten virtually, because she was fantastic.

I taught a 7th grade class virtually and I sincerely believe they got as good an education that year as they would have if they were in the regular classroom. The evidence is purely anecdotal, but one of my virtual students won an award as one of the Top 8 students in our entire school board (90,000 students!) when she graduated high school. But I think for most kids, the virtual learning years were absolute and total wastes.
