That's been my main argument for why LLMs might be at their zenith. But I recently started wondering whether all those codebases we expose to them are maybe good enough training data for the next generation. It's not high quality like accepted stackoverflow answers but it's working software for the most part.

If they'd be good enough you could rent them to put together closed source stuff you can hide behind a paywall, or maybe the AI owners would also own the paywall and rent you the software instead. The second that that is possible it will happen.
