To be fair, I'm inclined to believe that most of this pressure to lean (if not rely) on LLMs is not coming from programmers, but rather from middle and upper management: banks are resisting this not because their programmers are holding some kind of line, but because management is not giving-in to the LLM siren call. So that tour of duty, while a good idea, would be more about teaching management skills than anything else.

The normalisation of inexplicable failures is, in my opinion, the consequence of programmers being unable to refuse their managers who have fallen for the LLM siren call, lest they lose their jobs.
