And the commidiziation - ten years ago was 2014 and things like GoToMeeting existed, and were "barely capable" but could share screen, audio, and if your connection was good enough, video from your grainy webcam.

But lots of people weren't using that, they were still stuck with telephony-based videoconferencing, with polycom devices in the middle of a conference table and dual ISDN lines and stuff, stuff built out in the prior decade.

And then connections and cameras got good enough that Zoom could "just work" without all the hassle of following the rules, etc.
