Also training new people is annoying when things change too often; people can already use Jira/Linear/Monday/whatever , they don't want some completely flexible thing that is malleable.
Also, people are not all perfectionists with long term goals and visions. People who 'change' some part of their work flow that helps them NOW; they won't care about speed, scaling, deployment etc, so they will do something to make their work easier and then leave it there and possibly ignore it forever to rot. Which might have all kinds of fun implications.
I guess when we have AGI with a few 10 million+ context window for cheap, it will be different but the current llms would just leave a massive amount of rot all over the place, quickly forgotten and not usable by anyone but the original creator.
