Is this constitutional? It sounds like a pretty clear breach of the anti-commandeering doctrine. The federal government can't simply issue commands to state legislatures.
Federal law might supersede state law in areas where the federal government has express powers, e.g. interstate commerce, but if a state is adding AI-related provisions to existing policy in an area it already has authority over, I can't imagine how Congress could attempt to suppress that.
Sure, federal law could likely supersede state law if a state is trying to restrict AI as a commercial service in itself, as that would cross into interstate commerce territory. But if a state already has regulatory authority over e.g. how insurance companies operate within their jurisdiction, adding provisions that relate to how AI is used in the process of providing insurance coverage doesn't seem like something the Congress could legitimately intervene in.
