I would argue that with the rise of coding and debugging agents, the AI data centers provide (or will in the near future) even more benefit than a car factory, in terms of digital infrastructure. These technologies are just a lot more invisible so we don't realize how important they are.
I think AI bug scanning is a good thing, it will ensure almost all high severity get caught before entering prod. There can certainly be downsides but I am personally all for it.
All this would do is drive criminals to poorer countries that can't stop crime as well. Just like many scammers being based in South Asia, or billionaires moving their money to tax havens. It just takes one country to allow this stuff or at least not stop it, and your treaties are just pieces of paper.
