I say that as a VIM user who has been learning VIM commands for decades. I understand more than most how important it is to invest in one's tools. But I also understand that only so much time can be invested in sharpening the tools, when we have actual work to do with them. Using the LLMs as a fancy auto complete, but leaving the architecture up to my own NS (natural stupidity) has shown the default models to be more than adequate for my needs.
