alt Hacker NewsAI is a bit different in that unlike the rail tracks and the dark fiber the data centers arent actually going to be finished. It's much more of a stranded asset - there will be piles of chips and 1/4 finished construction projects, not usable assets.
No doubt somebody will use the assets for something but it's still wildly more wasteful than either railroads or dark fiber.
You don’t think there were half-finished rail lines abandoned when the companies ran out of money?
