Why do we even have to have a fixed, recurring meeting? That's equivalent to polling a server periodically and asking "hey, any event happened?" - which is extremely unscalable, and should be done only in situations when malfunction of event-driven mechanics is expected. Same with people - if an employee is trusted, meetings with them should only happen on an event - when there is a change of plans, some new work to be done, et cetera.
We have asychronous communication - so why not asychronous organization?
