The idea that you can just ban drinking and driving is a fantasy because there’s no technical way to actually guarantee enforcement.

I know that sounds ridiculous but it kind of illustrates the problem with your logic. We don’t just write laws that are guaranteed to have 100% compliance and/or 100% successful enforcement. If that were the case, we’d have way fewer laws and little need for courts/a broader judicial system.

The goal is getting most AI companies to comply and making sure that most of those that don’t follow the law face sufficient punishment to discourage them (and others). Additionally, you use that opportunity to undo what damage you can, be it restitution or otherwise for those negatively impacted.
