Most meetings (by far) could be done in minutes. Instead (and I have 1000s of anecdotes literally) people like to pleasantly do things, make jokes, laugh a lot etc. Do painfully long introductions (while everyone was in the mail and already checked Linkedin etc). But worse: ill prepare or not at all and just improvise. Worse yet: see it as a break or even (half) day out. There is place for this, but that's not something that should be the norm. It's teambuilding, sales etc and it's important. For normal meetings, when prepared, meetings can be done in minutes; send an agenda upfront, let people do a few rounds of discourse about those points in the agenda via mail/slack and give them a chance to do some research. Then discuss and decide efficiently.

There are enough exceptions but that's not most meetings. Most meetings are not about a critical company policy or about a critical technical dilemma where core infrastructure has to be changed. Etc.
