America on Data Centers: listen to 10,000+ city council comments

https://www.americansentiment.com/datacenters
28•afandrew•1h ago

Comments

afandrew•1h ago
This is Andrew, Founder/CEO of Prophecy Gov (AI agents for city governments). We operate American Sentiment.

Our main focus is building AI tools that serve city staff. We also create data from public, online data sources; in this case city council videos.

Data center development has reached a fever pitch nationwide. We started American Sentiment to help AI leaders, researchers, and the public better understand and respond to local sentiment nationwide.

The American Sentiment on Flock Safety is next!

Analysis: https://x.com/andrewfang/status/2117048211051532555

Findings include:

-73% of meetings had 0 people speaking in favor of data centers.

-Water use was the #1 issue. And only 1 in 5 comments mention AI!

-Elon Musk was mentioned more than Sam Altman, Peter Thiel, Mark Zuckerberg, Jeff Bezos, Bill Gates, and Kevin O'Leary combined.

-Data center opposition is heavily bipartisan.

Is there any information or evidence that the opposition and the people at these meetings clearly understood how they would stand to benefit?
tptacek•56m ago
Negative comments on data centers, or power plants, or day care, or apartment buildings, or coffee shops, or new fire hydrants are exactly what you'd expect from the (demented, sometimes literally) municipal public comment process, which sharply biased towards negative comments structurally --- people turn out because they're risk-averse and don't want to see change that could impact their own homes, and virtually nobody turns out for the abstract upside of new development --- and also demographically: public comment skews sharply older, wealthier, and towards homeowners.

The public comment process is an anti-democratic pox on our system (all the political systems that support it) and we should all be shifting to a mode where we more openly impeach it. Public comment is one of the first principal components of the American housing shortage.

ryandrake•45m ago
What's the alternative? Without public comment, politicians will just do whatever they want without accountability or open opposition. With public comment, politicians will still just do whatever they want without accountability but at least there is a record of opposition.
jrflo•27m ago
I’m not sure there is a good alternative, but it is a problem. So many public infrastructure projects in the US are shot down or neutered because of short term issues outweighing long term upsides.

Short term how? As in "you'll get used to it"?

lnkdinsuxs•23m ago
> They should invest money into improving electric and community infrastructure

The problem with electric and community infrastructure is that very few electric infrastructure is owned by the community, but that's not the core issue because the other infrastructure that is indeed owned by community has people in the community split on what's useful and what not.

Imagine how difficult it is to decide where to go out to lunch in a group of people. Now up the stakes to getting people to agree on whose backyard and where holes and trenches and dug and electric poles and power stations are put up.

Waterluvian•33m ago
If there’s really trillions of dollars of market cap to be had, why not just build in the middle of nowhere northern Québec and Ontario and build your own damn dams and infrastructure?

You’ve got a ton of water. A ton of famously cheap hydro electricity potential. An entire service industry for remote mines (who will build your roads and power). And you’re not being an unwanted bastard.

My sense is that the answer is very simple: because they can just use someone else’s.

akerl_•29m ago
Is there a network backbone running through the middle of nowhere northern Québec and Ontario?
tomrod•28m ago
They are running loads of fiber. If it's worth the trillions then it's worth some easement beside a railroad.
akerl_•21m ago
In the model it sounds like you're suggesting, instead of building a datacenter in the middle of the US along an existing internet backbone (a move which is already drawing tons of public criticism), they could build in rural Canada and also buy up easements to lay an entirely new set of high bandwidth pathways through rural Canada to connect those datacenters to the rest of the world?
jacquesm•19m ago
I'd love for rural Canada (or what is left of it) to stay as pristine as it is today. Sticking a datacenter in there sounds a bit like putting on in the Grand Canyon or Yellowstone (though, Yellowstone might be the better of the two with respect to Geothermal energy).
lnkdinsuxs•32m ago
Data centers and power plants to power them are the new oil.

Also, just like oil is dirty, bad for the environment and kills people, so will the data centers. And the power plants to power them.

Our options are not to not have Data centers and their power plants but whether to have them built elsewhere (even outside the US) and pay rent or own them and get paid the rent.

Arguments about having more efficient or green Data centers and power plants miss the point. Engineering is a process of iterative improvement - you don't begin with the perfect product, you begin with one that crashes, burns and breaks some bones.

It's understandable though that no one one wants to be "it".

BatchJob•13m ago
Sounds like people figured out how unsustainable data centers are and that they create no jobs.

That should be enough to stop it. But not in America.

WarmWash•8m ago
By my job their is a large vacant lot where they wanted to build a distribution center with over 125 truck bays. Absolutely gargantuan. Guaranteed trucks coming and going non-stop, lots more traffic, lots more noise, diesel engines idling all day. There is a school and a neighborhood immediately adjacent on one side, and commercial space and a minor highway on the other sides.

Apparently the developer was approached about the possibility of building a DC there, and it set off a five alarm fire of hysteria in the town. Of course, no one even blinked about the warehouse.

So now we are probably gonna get the hundreds of trucks 24/7 instead of the large quietly humming box (that would also probably increase tax revenue by 30%).

nickstinemates•1m ago
Bring back the $50k house. Thousands of them. Have the data center builders build communities around the data center. Sold to first time home buyers only, with a X year lock-in period. Effectively free energy comes along with it. Prop up community infrastructure so small businesses can proliferate.

Make the AI companies fully subsidize it instead of government.

It would change the sentiment in the country in an instant as affordability wrt owning a home would be in reach.

Not talking about data centers specifically here, there’s a few public transit projects near me that got killed/neutered because people didn’t want to live near a construction site, while it would have been beneficial long term.
jacquesm•24m ago
Datacenters are not really public infrastructure though. They are private infrastructure and even though the outcome could well be similar there is no link between the two.

Where I live data centers are extremely unpopular with the general population simply because the process around the decision making for these is opaque, the benefits do not seem to be shared with those that suffer the consequences and we've been telling people for the last 40 years or so that they need to conserve energy because of global warming. In that climate (heh) pushing data centers is an uphill battle, and it probably should be.

jrflo•19m ago
Electricity is a utility, but is privately owned in the US. Everyone relies on data centers just as much as electricity in modern life. There are obviously exceptions for mega ones like Elon built in Memphis, but the vast majority are just normal infrastructure
jrmg•19m ago
That the process is sharply biased towards negativity is a cogent criticism.

Two alternatives: - Trust our representative system and have our elected representatives make decisions (ha! Although perhaps people would pay attention to local elections more if they had more direct consequences…) - Randomly select people to comment, like jury duty.

It’s not impossible to think of systems that take public opinion into account that are not the exact system we have now.

With public comment, politicians will still just do whatever they want without accountability

This is very obviously not true to me. Is there really nothing in your area that’s been cancelled or interminably held up by the public comment process?

dantillberg•18m ago
I think tptacek means to emphasize the "public comment process" as opposed to "public comment" in general. Generic public comments/discussion are great (I think tptacek would agree because... they're commenting publicly).

It's the public comment _process_, where these Public Comments are given special status and power, that acts as a general drag on governments allowing anything. It's not _democratic_ because these Public Comments skew very unrepresentative. It's a sort of veto power granted mostly to people that don't have better things to do.

The clear alternative I see is to simply empower elected representatives/leaders to make these decisions.

sarchertech•12m ago
No he is on record as telling elected officials to ignore people showing up to town meetings, writing letters etc… because he believes that negative comments are overrepresented.

Which may not may not be true, but you could say the same thing about votes on a referendum, or names on a petition. One side or the other is in most cases more likely to turn out. That is just how democracy works. You can’t divine the true will of the people, you can only act on their public participation.

Anything else is just a license to politicians to push through anything they please.

A company is trying to push through a very large wood burning power plant a few miles down the road that will impact air quality for half the state. If people convince politicians that dissenting voices are overrepresented, that’s one less tool we have to stop things like this.

fasterik•7m ago
>No he is on record as telling elected officials to ignore people showing up to town meetings, writing letters etc.

I don't think that's a charitable reading of what tptacek was saying. I read it as: ideally, democracy should give everyone an equal voice regardless of age, political views, or economic status; local political participation skews heavily toward negative affect and toward older, wealthier homeowners, giving those groups a disproportionate voice in the process. We should move toward alternative processes that make it easier for everyone to participate, not just people who have the luxury of showing up to a town hall.

sarchertech•1m ago
>local political participation

Voting skews older as well. If you don’t participate you don’t get a voice. We can’t try to divine the public’s true intent.

We should be making it easier to participate, not giving politicians an excuse to ignore those people who do participate.

jacquesm•11m ago
> It's not _democratic_ because these Public Comments skew very unrepresentative.

Then you need to fix that.

akerl_•2m ago
Which "you" are you talking to here?

If your case is that we should strive for a social/economic state where everybody is equally capable of taking a couple hours to go stand in line and have their voice heard at a governmental public comment section, you have my vote.

But I don't think any of the folks here have the ability to "fix" the reasons that today, the people most able to do that skew heavily towards the old and the wealthy.

> The public comment process is an anti-democratic pox on our system

This just sounds like your ideas are bad and you’re upset that no one supports them.

happytoexplain•31m ago
This is hard to follow.

Some people have opinions that are perfectly human, but that you may certainly disagree strongly with. And yes, some people have straight up crazy opinions. And yes, some people have selfish opinions.

So... your answer is "fuck the people"? What are you even talking about? This is a necessary part of government. You are not the keeper of Correct Opinions. You're suggesting doing the thing that citizens historically get their weapons out to (rightfully) eject from civilization.

jacquesm•27m ago
So, that sounds like a great opportunity to engage the younger, poorer and the homeless then. That will certainly give a lot more perspective, but I doubt the outcome would be very different when it comes to datacenters. With respect to the housing shortage I suspect it would give a completely different outcome.

Also: you can't really blame those who do show up for a democratic process for having the wrong ideas relative to those that don't show up.

Public comment is a feature of the democratic process, I don't see how it could ever be seen as anti-democratic.

bobsomers•21m ago
What a dogshit take. The public comment process is anti-democratic? So the public having less input in the process and letting local officials do whatever they want is somehow more democratic?
cucumber3732842•10m ago
I live adjacent to an industrial area. I showed up in support of a proposed recycling center. I lowkey hope it's loud and stinky because I want the vicinity to be an unappealing place to live because then the people I find unappealing will self select to live elsewhere but I didn't say that. Instead I mocked shortsighted environmentalists and out of touch ivory tower types who want everyone to recycle but also want to impose supply side restrictions on that.

newobj•5m ago
Ah ninja smoke bomb out w/o proposing any alternative. Handy.

Not to mention hilariously conflating public comment on data centers (massively unpopular) with local weirdo NIMBYism on things like "coffee shops" and "fire hydrants". We all know every city has people that just love to speak at the city council meetings. Can't take it in good faith that you seriously think it's the same thing that's going on with opposition to data centers.

Waterluvian•15m ago
By and large we aren’t hesitant to take a portion of the remaining 80% of undeveloped Canada and do useful things with it. I can’t speak for all Canadians but that’s just not been a point of contention.

The amount of surveyed untapped hydro potential is something like 110GW. Though to be fair I haven’t studied any of this too deeply since grad school (which I refuse to let my brain appraise how long ago that was.)

akerl_•11m ago
How broadly have you shopped this idea? Most Americans weren't anti-datacenter-in-my-state until this recent wave of tons of datacenters popping up in their state.
Waterluvian•4m ago
Mark’s a bit busy… but I actually chatted about this with the hockey parents at the rink this morning. They’re anti data center mainly because they just feel the companies (apparently they think it’s all Google and Facebook and have no clue Anthropic or OpenAI is a thing) will ruin the town and cause blackouts and ruin the water pressure (our water pressure is kinda weak). When I suggested “what about like an hour north of Sudbury?” they went from negative to I’d say indifferent. Except our goalie’s mom who was a hard no under any circumstances.

What I found interesting was that none of them had a single thing to say about the actual AI tech. Mind you n=6 or 7.

I'd be all for it as reclamation of the territories that have already been damaged pretty much beyond recovery due to the oil industry. But the Canadian North is very precious. Besides, I wouldn't want to give my capricious neighbor yet another reason to 'protect' their investment.

If nothing works out domestically, this might very well be where the industry ends up.

The current attempt is to have domestic (in the continental US) AI - because owning the infrastructure is way more valuable than renting it.

andsoitis•19m ago

ipdashc•11m ago
They are building them in the middle of nowhere. I've looked up sites for data center projects before and it'll literally be in some empty field far away from any homes, and people will still complain as if they're flattening a neighborhood. It's a little ridiculous.

That said, I agree they should put them in Canada and similar regions, it seems like a no brainer resources-wise for the reasons you mentioned. The reason they don't is probably that it's vastly more expensive to work on remote sites like that. Mines and dams do it by necessity, but it's a big undertaking to build stuff a full day's drive (or bush plane flight) from the nearest city.
