As if engineers, especially those writing software to handle financial transactions (which are usually in regulated businesses), don’t know how to write conformance tests with invariant cases.
having seen both (a) mission-critical human-built systems become nightmares for maintainability and extensibility and (b) bleeding-edge ai coding agents confidently and quickly fix a wrong problem in the face of an issue (or fix it in a slightly wrong way), I remain skeptical that this great de-skilling will all be perfectly fine.
of course, if you aren't looking at the code you won't fucking know until someone yells...
>concerning for money-handling firms
The real world is robust. It's okay for money handling code to have bugs. It's not the end of the world and AI will be able to have a lower bug rate than humans.
This is true. The world will go on. But your business will lose more money than it gained by not paying attention to the code. It will lose money because it will have to compensate customers or lose customers. That's how the world maintains it's robustness.
