It's not even about requirements. It's about responsibility. Someone has to take responsibility for the code and the product. Someone has to hotfix a bug that's costing millions of dollars an hour and someone has to be blamed for a bug that's consting millions of dollars an hour.

Not really. The secret of our society is it wouldn't work if people with a controlling interest in things ever faced personal responsibility. Who got blamed for the Iraq war? How much did that cost? The theory is if you tried to blame someone then some future president wouldn't be able to declare war. You don't know how the law works apparently. Corporate law is pretty much the same. The economy doesn't boom if CEOs can actually be blamed for things. You don't blame a "someone" that's what incorporation does. If some code does a booboo just put a $ amount on it, withdraw the funds and move on. The media will focus on the humans because of the drama, but they are largely irrelevant. It doesn't come out of their pockets. A human is already window dressing in this status quo. A LLM has no reason to do the sorts of things that violate such legal protections, be it of a president (none really apply) or a CEO (good luck getting a CEO to take personal responsibility for anything short of outright fraud). If it suddenly goes haywire the law already has a concept of vis major.

The secret is individual humans are already largely irrelevant to our society. That's how we got here. The trend will only continue.
