This isn't a new question: quis custodiet ipsos custodes?

In general, the way things work in the USA is that megacorporations write the regulatory frameworks for their own industries. These regulations are typically burdensome enough to be shouldered by the megacorporations while crushing the smaller players in the given market(s). The AI companies are now advocating for this very arrangement. They will likely get they want, and with that they will gain legal shielding for bad behavior just like Dupont, Monsanto, and so many others.
