I think you might misunderstand. The regulation isn't about what OpenAI and Anthropic can do. It's about what you, a citizen, can do.
Consider this though: Regulating AI models in the US benefits the data centers, not individuals. That's where regulated models run. Regulated models creates demand for data centers.
Dario wants regulation so he can continue to sell access to his data centers.
But yeah if you only rely on money and not people power campaigns are expensive and hard, when you have entire communities backing you things become slightly easier.
