I understand why they did it, but it’s super annoying.
Given the intervals between running Homebrew, you just know it’s going to spin for a minute or two updating every damn time you try to use it, usually when you want something installed fast.
This comment actually just spurred me to find this (https://gist.github.com/jb510/99f12b1ac70f1cf8b780) which may fix the issue of forgetting to manually update.
