This is a well-written, cogent, and carefully considered article whose conclusions I disagree with almost completely.

Many of the specifics have already been discussed, but a major benefit of video calls has been missed: Screen sharing. Computer interaction is largely a visual medium in modern times. It is so much easier to look interactively, together, at something than to try to type out what's going on. This applies to both instructions on using or doing something, and especially to code review or discussion.

That doesn't mean you screenshare or call for most problems - you don't. But for some things it just ends up taking infinitely less time, especially when you are having trouble getting one side to understand via text.

I work for a fully remote engineering team that has been remote for more than a decade - COVID changed very little of my organization's culture, as far as I know (I joined after the pandemic started). One of our core rules is "if a conversation is not going well, or people don't understand what's being said, take it to video," and that has served us well.
