When the code spit out by an LLM does not pass QA one can merely add "pls fix teh program, bro, pls no mistakes this time, bro, kthxbye", cross their fingers and hope for the best, because in the end it is impossible -- fundamentally -- to determine which part of the prompt produced offending code.

While it is indeed an interesting observation that the latter approaches commercial viability in certain areas there is still somewhere between zero and infinitesimal overlap between prompting and engineering.
