One thought I've had about AI and programing is that you'll run in to a similar problem. Code is a bit special because it's a language that's understandable by both humans and computers, and when you're programing you're essentially writing for both audiences at once.

Voice is maybe not as important when writing code (although you still want to keep the coding style consistent) but even so I think that writing code by hand has the advantage of you being able to express your thoughts in a more coherent way than the output of a handful prompts will. The problem isn't just with however powerful the AI model is, but that prompting is a kind of vague and indirect way of interacting with the system and it necessarily introduces another layer between the author and whoever ends up reading it.
