If we're going to have AI regulation, this is where to start. If a company's AI service acts for a user, the company has non-disclaimable financial responsibility for anything that goes wrong. There's an area of law called "agency", which covers the liability of an employer for the actions of its employees. The law of agency should apply to AI agents. One court already did that. An airline AI gave wrong but reasonable sounding advice on fares, a customer made a decision based on that advice, and the court held that the AI's advice was binding on the company, even though it cost the company money.
This is something lawyers and politicians can understand, because there's settled law on this for human agents.
I guess what I'm saying is - we've always had this problem.
