Correct, it isn't self-evident to me at all, but it depends on what is being communicated, of course. In-person communications are slow, and half of the communication isn't really about the topic at hand.
In terms of meetings, I've only rarely seen a meeting that couldn't have accomplished the same goals in 1/10 the time if it done without being a meeting. Whether in-person or zoom. The information density is far too low, too much time is taken up with things that aren't moving toward the goal, etc.
This isn't self-evident to me at all.
