This is not correct. They can say "sorry" which makes them as accountable as ordinary developer.
I've found recent versions of Claude and codex to be reluctant in this regard. They will recognise the problem they created a few minutes ago but often behave as if someone else did it. In many ways that's true though, I suppose.
Ordinary developers get fired for poor performance *all the time*.
LLM based solutions don’t need to stay dry and warm at night, with a full belly, possibly with their sexual partner with whom they have a drive to procreate.
That's not what accountability is
