Is that? How're the lawsuits against gun manufacturers working out?

This is a specious argument. I have not studied the case law, but I would guess that the reasons why courts decide in favor of gun manufacturers generally don’t apply to AI. Becauee the guns in question are not able to autonomously shoot people, and because they generally work as advertised.

A more accurate analogy would be Tesla and Autopilot. And they are being held liable in courts. They are being held responsible for autonomous behaviors that are not fully under the control of the operator, and they are being held responsible for misleading operators about the capabilities of the product.

Boeing got in trouble for MCAS, with a comparable legal basis.
