This is like saying "writing code is solved, all we need now is somebody to blame because it doesnt work"
If you understand the codebase deeply and have trust in it can roll out changes quickly without manual testing you can run circles around the people scratching their heads wondering if this vibe coded 2,500 pull request is going to be the one that takes down the system for a day.
IME vibe coding isnt just not capable of building these foundations, it actively chips away at them where they already exist. shrug
