Hacking sort of depends on there being a bug in the targeted infrastructure, a so called exploit, which you can, well, exploit. If you don't have one, all you can do is brute force attacks, which are impractical, no matter how much you're willing to invest. You may want a high end llm looking for vulnerabilities, but the enemy probably doesn't have enough stuff to justify using more than a handful of those. And you'd want those computers running in underground bunkers, not in exposed data centers on the surface.
The whole data center build out only serves to excite investors. It's a waste of resources in every other regard. A symptom of late-stage capitalism.
