I think the reason we're not seeing many examples yet is that the full loop doesn't work completely autonomously yet. There's still a human in the loop at some critical points - specifically testing against a spec (runtime testing if say working on web or mobile app before shipping to users). LLMs can do compile time testing and validation, unit tests, and can write your end to end tests, but if you're shipping software to users, there's still a human somewhere involved. This isn't even mentioning marketing and actually getting your software into the hands of users - which while it can be automated, a lot of marketing with AI is still sloppy.
