Honestly, I think what you consider „good code“ is just shifted from what the previous commenter considers „good code“. Prompting is about giving enough information so the AI can solve the task without needing to reconstruct a lot of context. Most people using AI somewhat regularly will have figured out to write good enough prompts. I‘ve never seen AI generate perfectly good code beyond hello world and the fibonacci sequence. And by perfectly good I mean I wouldn’t change beyond 30% of what it produces, which is not a high bar.
