I think the role of llm’s is once you have a rich enough understanding of what you want - you can speed run to build it. And then perhaps re-build to cover the issues created by the llm.

Problem for model producers is - the revenues they get from this mode of work is tiny relative to what they need.

And there's a few domains where the spec is clear and the solution kinda easy to implement. But it breaks the contract with your users or downstream projects and you now have to coordinate communication. Code rarely exists in isolation.
