“It is just a building.”
just a building that consumes VAST quantities of electricity, massively stressing the local grid, and causing power prices to skyrocket ... and all of that power is 100% converted into waste heat, because ICs are pretty much nothing but micro-toasters. plus once that “just a building” is built and operating, the number of jobs needed to keep all of that running is close to nil ... all the software activity and most of the maintenance will be offsite, probably in India ...
So, fill a football-stadium-sized “just a building” with hundreds of tons of ICs, and install a million small fans to cool the thousands of racks containing said tons of ICs, and then consume massive quantities of water for evaporative cooling to eject that heat, and add the sound of those small fans and the big fans for evaporative cooling that can be heard for a mile .... so, it’s “just a building”, you know, like a vulcanizing plant, a nuclear power plant, auto-manufacturing plant, and so forth, only with no jobs and does nothing except consume massive quantities of local resources ...
