I was thinking about this in recent weeks and I think I’ve actually changed my mind on it.

It’s not really possible to measure how much it would cost to not have a meeting, and I think it’s pretty obvious that if there were no meetings ever, it would hurt a company a lot

Yeah, I agree it's a silly metric. But it's kinda also a good reminder that meetings do have a cost associated with them, so they should stay short, focused, and held only when necessary.

"This could have been an e-mail" should never need to be said.
