I'm also one of those people. I learned both Vim and then Emacs + evil-mode, used them for a decade, and then one day I changed computers, couldn't be bothered to set up .vim/.emacs.d and stopped using them except for Vim for topical config edits.

Now I like to have a GUI that has things like a right-click menu instead of having to rely on maintaining muscle memory for everything.

Of course, another part of that, I think, is becoming older. Mastering some aspect of the computer or software like Vim just isn't interesting to me like it used to be.
