Answer: Which part of the constitution gives the president unilateral authority to make rules for artificial intelligence through executive order and ban states from having their own rules?

For context, this is a question I answered on Quora

For context, Trump wrote on TruthSocial that he would sign an EO this week establishing nationwide rules for AI and would preemptively bar states from passing laws for AI development and use.

Of course, the only debatable means by which the federal government could assume preemptive and broad discretion over AI is through the commerce clause and the dormant commerce clause that prohibits states from erecting interstate trade barriers. But that authority is reserved for congress to decide by vote not for the president to decide unilaterally through an executive order. If the executive could just make rules about anything under the sun without congressional approval or judicial oversight we would no longer even have a republic but a functional dictatorship.

If we take a more Originalist interpretation, the enumerated powers not specifically delegated to congress are reserved to the states (10th amendment), but since this has already been thrown to the wayside by the leviathan that currently occupies Washington, a federal law establishing uniform rules for AI development and use would probably hold up in the courts.
