There's no guarantee the boilerplate an LLM spits out will be up to date. It'll almost definitely have some outdated code in it's dataset that it can reference.
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)
