I think this makes sense in the abstract but not always in practice. I have been in many long back-and-forth Slack conversations explaining some piece of knowledge that would be better as a 20 minute meeting.

And so I think a better "mental model" of meetings might be functionally the same as human communication in general: for smaller and faster-acting groups, live communication (meetings) is often more efficient than writing. Especially when the team is small and needs to act quickly, because then the time cost of 5-20% of your manpower spending an hour to write out something that takes 10 minutes to explain via a video meeting walkthrough is not optimal.

But the more people your group has, the more you'll need to shift to a text-based communication method.

(This is also why I think remote work makes sense in many contexts, but does somewhat become less efficient in smaller, fast-moving companies. Unless you replace the in-person ad hoc meeting with a rapid on-demand meeting culture, you'll have some inefficiencies and move slower.)

I have seen some attempts to use AI transcription bots as an attempt to square the circle here and commit ephemeral meeting information into durable text information, and in general they aren't too bad actually.
