It seems like they should be changing the rules to outlaw that ongoing activity rather than considering it grandfathered. If a kid buys a loud car stereo and then the city passes a noise ordinance, it's not like the kid gets to keep on blasting his stereo because he already bought it.

You are absolutely smart enough to know the difference between a data center for internet-distributed software and a data center full of GPUs solely for AI, along with the attendant increase in power and cooling needs. Don’t play dumb, please.

Almost nothing this scale can be built without subsidies because in the U.S. no company is willing to actually buy anything on their own. Wal-Mart forces local municipalities to pay for the buildings to be built through subsidies and taxation delays. Amazon does the same with their warehouses, distribution centers, and Whole Foods. NFL and NBA stadiums as well. Either the locals pay for the "privilege" of having their money vacuumed out of the area or these places don't get built. And as many city and county level politicians are very poorly versed in terms of macroeconomics they fail to understand that the addition of those two hundred jobs will cost the area two to three times as much as the employees will make because they can't collect taxes from an entity that is increasing wear on the roads, increasing load on the electrical and water infrastructure, and creating new external costs in the form of garbage disposal or light and noise pollution.

These datacenters are like that, but taken even further because they're attached to an industry used to ridiculous tax breaks or lack of taxation in the first place, constant investor capital, and continuous rapid growth. Software production and digital infrastructure have grown up in a wildly different environment from traditional retail and shipping logistics, but they're taking the most successful (and harmful) expansion tactics from retail and shipping.

Unless you can kill subsidies outright for anything connected to a national or international entity and provide enough specifics to prevent them from hiding behind shell companies then it's a losing battle to say "don't subsidize them." They'll either force you to pay for them or they'll move somewhere that will, and those with a poor understanding of the situation will complain for years that everyone lost out on a "big opportunity" by refusing to pay for their own predation. That complaining can echo into local politics for years afterwards and affect the outcome of various policies, either by denials out of spite or misplaced regret over the previous big project, or by politicians being voted out because of their opposition to a Wal-Mart or such being built via extensive subsidies and an agreement to collect no taxes for ten years.

Easier said than done. They don't let me in on those meetings.
