A lot of comments on VIM here. Vim is a terrible example and a pretty bad design overall, objectively. Legends of great productivity with vim is highly legendary, i.e. fiction. Classic Notepad/Word and similar Guis that have been widely adopted in Linux windowing systems are clearly superior and that's why they're so widely and silently adopted. Not a lot of fanfare for hierarchical GUI menus with keyboard shortcuts.
Your making a subjective statement not an objective one about VIM.
Objective would be making the statement that not all GUIs need to be keyboard-driven manged or have accessibility built-in.
Example, GUIs in automation are primary touchscreen driven and have user requirements base on the environment they are in.
GUI standards are objective to who the users actually are or will be.
