The discussion here is precisely because it is not fully paid for by the corporation.
Then a new DC creates another 300MW of demand and builds 300MW more feeds
Then the DC goes bust, you're left with 350MW of potential supply and 50MW of demand
Compare with a highway, you had a 2 lane road, and it was fine, with 1000 cars an hour, then someone expanded it to 8 lanes and filled them with another 3000 cars an hour.
Then they vanished, and you're left with an 8 lane road for 1000 cars an hour, paying 4 times the maintenance for extra unneeded capacity.
In reality there's nothing to gain in theory, and in practice it correlates with higher energy costs
Basically every AI company using "catastrophizing" and "ragebait" as their marketing strategy is working so well that normies are afraid they're going to lose their cushy do-nothing desk jobs. Hence the braindead/conspiracy narratives that data centers are going to drink all the fresh water, give your kids cancer, kill the plants and quadruple your electric bill.
What's most hilarious about this; dramatically expanding the power grid is absolutely necessary to get off of fossil fuels, yet the same people who used to scream about climate change are now trying to block grid upgrades paid for by data centers. With zero awareness of the irony.
This will only get worse as time goes on because first world countries are aging at increasing rates. Old people hate change. They're deficit spending their children's future labor while obstructing the creation of anything productive that might dig us out of the hole they put us in.
