The fundamental challenge is that it will never be economically feasible to provide the necessary defense hardware at scale. Iran beat back the US military (“most powerful military in the world” quote unquote) and Ukraine Russia’s military on a shoestring budget. You can protect some targets some or most of the time, you cannot protect all potential targets all of the time.

If someone wants to take out a data center, they will likely succeed assuming they have the resources (probably military drones, but perhaps more traditional ballistic artillery). The world has become a more dangerous, volatile, and unpredictable place, for gestures broadly at everything reasons.
