I agree in certain circumstances. For example a file manager I don't understand why people use in a terminal. When I need to do like batch deletions or something I can easily just write a couple terminal commands. Everything else I just use the default file manager. Either Finder on MacOS or the Gnome one on Linux.

But stuff like vim, a terminal text editor, is simply more fluid and enjoyable than a GUI program. I've tried using vim plugins for various different GUI text editors like Sublime or VS Code but there's nothing like a personalized vim install. It takes a little bit to get used to the commands, but once you do it's like riding a bike. You just feel faster and muscle memory takes care of the rest. You don't actively think about it

same thing with for example package managers. it's faster to just press my hotkey to open up terminal, type in "sudo dnf install <whatever>" and it's installed. why do we need a GUI here? it doesn't make anything faster. In fact, it just gets in the way.

so some things GUIs don't actually improve. Some they do. It's a per case thing I think
