In the early days of online learning we had person-to-person email and chat (like ICQ or IRC) and that was about it. It was immediate and direct, but it was tiring and hard to keep up, so we latched on to alternatives like mailing lists and discussion boards. We're going through a similar phase with millions of new users and video chat. As this article describes, people are experiencing Zoom fatigue and are looking toward "asynchronous collaboration tools like Miro, Trello, and others" (such as Slack and Teams). But these take some getting used to (and I find it hard even to get people to work together in a familiar environment like Google Docs). More and more, though, as people become used to the new tools, and experience online life beyond Zoom, they'll find fewer and fewer reasons to return to commuting and sharing germ-space.
