I'm a lowly, very dumb user too. I ran Brew doctor and realized that the default installation is now in /opt/homebrew (which to my dumb ears seems like it solves most complaints I've heard about Homebrew). Since Homebrew threw a warning at me with my old install in /usr/local, I completely uninstalled and reinstalled Homebrew 3.0.
