I bet engineering loved traders tossing vibe-coded crap across the wall and demanding it be productionized. "It can't be hard, after all I've already written the code for you."
The details are very different, but variations on this theme have played out for a long time. I have seen fixed income instrument modeling systems 20 years ago that allowed Traders to put in limited C++ code to define new exotic instruments.
At least that stuff had guardrails around it.
This is gold! :-))
