There is a "need" vs "want" aspect here, but often the boilerplates that we reach for become out of date. In theory, an LLM producing these could remain up to date without maintenance, key phrase "in theory"
There is work going into giving the LLMs access to external data & systems. This is my basis for saying they will be able to stay up to date.
I have a very different approach I'm working on: https://docs.hofstadter.io/getting-started/creators (human-made blueprints that can be started from and later updated to bring in the upstream changes)
