Insurance exists. Money points to something in reality (usually).

Negligence and duty don’t change and the implementing human (the person checking for mistakes) will be just as liable as the human implementing someone else’s work today.

But true… it is unlikely the AI firms or the suits that force it into every nook and cranny they can will ever be held accountable for the mistakes it will inevitably make. Not without a couple catastrophes first.

I was thinking that, but then I remembered how often humans make mistakes and and don't check their own work. For me, a common example is loose/lose, which I only find in my writing by assistance from text-to-speech. Did you spot the deliberate mistake in this comment? Because that too is one I miss, when the two words are separated by a line-break.

Engineers already sign off on work done by others all the time. This isn't some new or radical concept. For civil engineering projects, you can face jail time if you signed off on bad work regardless of who did it.
