Data centers have been around forever. Supercomputers and other large racks of computer hardware have been housed in them for decades. They have done a lot of good for research.
Even if you didn’t have AWS and the like modern sites/tech products need a lot more hardware than your random desktop computer to work. And that needs to be housed somewhere.
The AI ones they’re trying to build now to try and stack tech feudal territory? Probably not. I don’t think the demand is gonna be there long term.
