I think part of it is that it gives us something to talk about. Taking umpires pretty much out of the game will kill a lot of great conversations.
Yeah, that's fair, and of course it's fun to bitch about Cowboy Joe or Ted Barrett. But there was a study published this past spring that said, for example, Cowboy Joe averaged 21 blown calls per game in 2018. If there's a way to reduce or mitigate that, it should be explored. It's just that the tech needs more time in the oven.
