I'm a vim user. for decades. Your post does not align at all with my experience.

If you prompt and hand-hold the LLM it is a big help. Things like boilerplate, basic crud etc etc is something I dont have to worry about anymore. And if I am looking at an unknown codebase or area, the llm can explain things to me, it's the rubber duck that talks back.

I'm not using vim plugins (yet) for LLM, tmux and a couple of panes etc is all I need at the moment.
