I think users feel the other options are better due to familiarity.

I generly find modern interfaces clunky and really inefficient to use and this iescoming from a younger person who grew up in win 98+.

After I actually spent some time on a cli and using vim there's no way I would go back. Sure I can put up with it but if you give me a choice I would use the cli and vim any day of the week. Unfortunately these days you need graphical applications for things so I use a tiling window manager as a compromise and would you believe I like windows 10 and 11 purely because I can use them mostly the same way.

I generally want a single full screen thing on my screen and to be able to switch "desktops" to another full screen thing. Add something like tmux (I settle for tabbed terminal when using windows) and I'm happy.

Modern windows and macos with multi desktop workflows does exactly that.

For applications I never want to move my hands from exactly the position they are in right now. Added bonus, don't make me search through a billion and one menus for a thing I want to do and specially don't make me practice my FPS aiming to hit the button.

Ironically the GUI applications I like the most have a fuzzy finder on a keyboard shortcut or every single action is available from a keyboard shortcut.

The ones I hate follow "good modern UI" you know like putting everything in a ribbon that scrolls across the screen for 20 pages and all the buttons are tiny and the screen is cluttered with crud.

So yes I will take vim over VS code for both UI and UX any day of the week.

Sometimes it's perfectly fine for a user who has never used tour product to not know how to use it fully.

Keep your fancy UX design Philosophy for the website that teaches how to use the app. I need UX to get out of my way, not make 5 functions easy to use and everything else a pain in the backside.
