> the first time I've really thought hard about how big a target data centers would be in any sort of modern peer war
Given the rapid and increasing rise of AI use in actually fighting wars, I suspect data centers won't just be a big target, they will eventually be the #1 priority target. Taking them offline won't just be of interest in terms of economic damage, it will be a direct strategic goal toward militarily winning the conflict.
If they hit AI data centers, 50% of software developers will convert to Islam. :)
xAI's data centers in space (should they happen) will push the frontier of war firmly overhead too.
Until it is clear that the use of AI in "actually fighting wars" doesn't put senior military people at risk of never being able to leave their own country again for fear of prosecution for war crimes, I'm not so sure that the "rapid and increasing rise" is going to actually be a thing.
