It is kind of bonkers if you consider that all of us already had "data centers" in our backyards already.
Every corporation and even most small businesses have had a machine room, wiring closet, or some kind of server shoved into a room, since 30 years ago now. They all had them in every office building you ever drove by, or lived next to, or shopped near. It's simply that people didn't even register them, because none of the general public really sees or knows what goes on in office parks, and behind the tinted corporate windows. It could be as benign as a toy distributor or as wicked as a defense contractor, and from the outside, they look alike.
But they've all had computers, and networks, for decades. And what we are seeing now is consolidation and concentration. The offices and parks and buildings are hollowed out -- they've laid off workers, they've gone WFH, and most importantly, they've gutted their machine rooms and removed on-prem equipment in migration to the cloud. So each and every company that migrated to the cloud has shrunk their own machine room's footprint by X amount that is reflected in data-center capacity by an identical (or perhaps larger) X. And that, of course, means that power, cooling, and resource consumption is not necessarily enlarged, but merely transferred and concentrated into DCs rather than power-hungry machine rooms, humming secretly inside every office building.
I look back to my first job--I worked at an ISP, and we colocated with the San Diego Supercomputer Center. The SDSC was a data center par excellence with the finest machines that ever existed on the floor. And I was still a kid when I'd be admitted to the main floor, I'd walk past a Y-MP, a Thinking Machine, an Intel Paragon, a Nearline Tape Robot, and there were our humble little pizza-boxes, sitting on a table trying to keep up with Usenet. Our own ISP offices didn't even have a machine room of our own, just a rack with a hub--yeah a hub--and a Sparc 2 pizza box to serve the office. We were already "in the cloud", as it were. More or less literally--SDSC was where they tested nuclear weapons, predicted the weather, and explored outer space, through the magic of FORTRAN...
So what people are complaining about is something they can see. If you're dying of cancer for 20 years but you never go to a doctor, you won't feel it. Once you see the doctor, the chemotherapy starts, and then you croak from the chemo. So this building of datacenters is simply bringing this into the open, and into the light. And people are angrily reactive at social media, and techbros, and surveillance capitalism, and AI-job-losses, and corporate hijinks in general, so data centers do give a focus to that futile rage.
But it's futile, and we all depend on data centers already, even before they are built, and we need DCs now to sustain our economy and our civilization as it already is. It's futile to resist and if you want to come in with a tractor to demolish them, you'll be arrested, and the Flock camera attackers will be hauled into prison too, and technology will just impassively march along as a juggernaut with no feelings, no remorse, and no mercy.
It's a pity; we were really nice folks for a few hundred years.
