Those are crashes that I found hard to fix because even though by human standard I'm both expert …

They’ll be forced to work on it when then the bugs in the new system are uncovered. If the system is simple enough someone might take enough time to understand and verify the test suite to the point where they can keep adding regression tests to it and maybe mostly call it done. They probably won’t do this though (based on the situation the company was in in the first place) and people will have Claude fix it and write tests that no one verified. And in a while the test suite will be so full tests that reimplement the code instead of testing it that it will be mostly useless. Then someone else will come in and vibe code a replacement that won’t have the bugs the current system does but will have a whole new set. And the cycle will continue. The same cycle that I’ve seen in the bottom 80% of companies I’ve worked for, just faster.
