The real reason there's a growing backlash towards AI datacenters is that people are afraid of losing their jobs to AI.
All those things you said are just excuses people are putting forward because "I just don't want to lose my job" is super backwards argument that makes them look like luddites. Most of those excuses can be entirely debunked or are flimsy at the very best.
The whole water argument is effectively a non-issue at this point, the vast majority of the new data centers are being built without evaporative coolers. Not to mention the fact that global Beef production uses around 200 times more fresh water than Global Data Centers (and that includes all the non-AI datacenters just running the basic internet and companies stuff that exists).
Power Grid and power pricing concerns can be easily addressed through legislation/regulation, which is exactly what's happening in reasonable jurisdictions like British Columbia in Canada.
The noise thing is... nothing. It's the same bullshit that got pushed for Wind Turbines. Sub-sonic, infrasonic, transonic... Bullshit. There's no scientific evidence backing up any of that shit, which is why people are pointing to random studies in non-name journals published by quack citizen-scientists who are promoting their Youtube channels.
They're also not building the damn things right next to millions of residential homes. They're in industrial parks, downtown cores, or out in rural areas. Here's a worst case scenario, Microsoft just built a new one in Vaughan, Ont (6100 Langstaff Rd) across the street from a suburb. It's a small two story datacenter next to a massive Costco distribution center that has thousands of trucks going in and out. It's still about 200 meters from the closest home, but across the intersection of two 4 lane highways which make enough noise (and air pollution) that any sort of data center is going to be entirely irrelevant.
Your average person simply sees no significant individual future benefit to having these built that would outweigh such a risk to their existence and value.
