In reality you can't reduce AI to replace only "Level 1 coding" and do only "typing". It will make assumptions about these "Level 2 and 3" decisions in its generated code. To reduce or control it you have to invest more into documentation/instructions and code review. You basically change the focus based on the assumption that "Level 1 coding" with all of that "hand-crafted" code was such a big waste of time and money. But it's a made-up problem.
On top of that a lot of vibe-coded projects that appear here and there seem to not even intend to let the AI do only the typing. They don't just let the AI translate "flow" and "architecture" into code. They make the AI translate their demands into code.
