> I asked some pretty straightforward questions about the specific legal issues involved
Perhaps you should ask a lawyer from the country that the precise laws of interest you. I'm not one.
I know only that there are no laws about AI containment yet and AIs are not guns. You could as well refer to what consists of negligence when it comes to backyard pools.
I'm also not really interested in discussing particular laws of US because China will overtake it in few years and they have a better chance of directing international AI laws. So whatever US comes up with will remain local and increasingly irrelevant.
