StrongDM is attempting that. The code they produced is not inspiring confidence on a relatively small scale [0], and based on what I saw with a cursory inspection I very much doubt I wouldn't find much deeper issues if I took the time to really dig into their code.
Don't get me wrong, "sort of works if you squint at it" is downright miraculous by the standards of five years ago, but current models and harnesses are not sufficient to replace developers at this scale.
"Get a horse!"
