I'm not a betting person but I am looking forward to the postmortem, whether or not AI was involved, and what their code to production verification stuff looks like now. This kind of thing should have been caught by automated tests.
There is an enormous amount of money invested in trying to prove the opposite, for this reason not only they will never admit it, they will actively negate AI was used. It happened before:
10 layers of approvals to get a reasonable change implemented, but this shit gets pushed to production instantly. AI is driving leaders insane - they actually believe they can stop operating with humans and take all of the money. Remember your pay is transactional. Never give them more than written in your contract, and there is no shame in playing dirty politics to advance within.
