I agree with Dr. Fauci that we need to get kids back in school as soon as we can be sure they will be safe. A child from an affluent home who has a computer and parents who can help if there is a problem are much better off than those in poor homes with no computer and parents lining up at food banks or trying to get to their jobs.
Even children from affluent homes are at a disadvantage if all their school work is done on a computer. Several studies have been published showing that children need to learn cursive or how to write by hand. Writing cursive helps children retain facts better than if they just see them on a computer. One study showed that children "with fine-motor writing skills early on did better later on". Another study showed that kids retain information much better if they have to take notes or write down information. I always took a lot of notes when I was in school, college, or medical school. I often just studied the notes when I needed to prepare for a test. I still take notes about things I want to remember and use a computer only for e-mails, book chapters, Google etc.
If I had children at home now I would insist on as little computer time as possible. If a child had to do on-line learning, I would be sure a lot of time was not being spent on social media sites, sexting, and e-mailing friends. Some children are having headaches, eye strain and other medical problems from overusing their computers.
