Points for effort, but this will do literal nothing to appease the opposition, since the "water use" thing is a myth anyway. It's probably good, it sounds like it will be more efficient and efficiency saves resources for other uses, but politically it's completely useless.

Do you have any references for this comment: '"water use" thing is a myth anyway'. I would like to show my kid who keeps complaining to me about AI water usage.

Would you like to work in the middle of nowhere?

After construction, not all that many people work at a data center. Some ops staff, maybe a small security team.

So let's spit on those 'not so many people' from our ivory tower?

Besides, it's not about people, it's about power. Pulling a few MW into middle of nowhere is prohibitively expensive.

Doesn't matter that's it's a myth, it's salient and has become a layperson talking point. This is an official post on nvidia.com that can be quoted: "The NVIDIA DSX reference design for AI factories has zero water consumption"

I’d love that heat in the winter. Imagine, free heat! Linus heats his pool with excess cpu heat. It’s all about using things wisely and not panicking. AI and datacenters are here to stay, you can’t fight them, but you can leverage their waste for profit.

> AI and datacenters are here to stay, you can’t fight them, Maybe you can't (or don't want to), but people can absolutely fight data center construction. Your lack of imagination doesn't bind others.

But why? I want cheap tokens. Build a data center on every block (or more realistically in all the empty space we have everywhere).

If you don't fight data centers, data centers won't seek solution oriented ways to lower their footprint. You are really saying that you can't fight data center demand. And that is true, but you can restrain their supply, increase their cost, and optimize on low impact approaches.

Then ask for legislation that they have to be powered by solar power+batteries or something

Yeah and it's a myth that fracking makes water undrinkable.

I'll bet anything you'd be the guy that won't drink a glass of the "perfectly safe, completely unaffected" water while making such utterly absurd claims.

The original paper that started this meme said "data centers consume water indirectly through the water used for electricity generation" and then counted water evaporating out of Lake Mead behind the Hoover dam as water use. This made the numbers seem gigantic, people got mad at it on social media, and 1 year later here we are.

how does this square against georgia just ignoring it draining the water supply, https://www.politico.com/news/2026/05/08/georgia-data-center... and reports of undrinkable water due to the ai center construction? https://www.bbc.com/news/articles/cy8gy7lv448o even in the article you linked, it admits AI data centers CAN harm water supplies "Individual data centers can sometimes stress local water systems in the way o…

"And its like he claims "its not ai data centers themselves, its the construction of them" as if its an important distinction that exempts data centers from harm. It's not."

But this has nothing to do with data centers, it has to do with construction. I think getting every mad at all new construction in general is a very dangerous path to go down.

Yeah but that's not what the discourse around water and AI is. When people speak about water and AI/dc's, they're indicating that water is being "taken" from other uses. As if a AI usage will oneday cause you to turn on your facet and nothing but an auto-tuned cackle comes out. That the well has gone dry. That water is a scarce resource (which, sometimes it is, esp. if you're drawing from an aquifer in the southwest)

A data centre's construction sentiment clogging pipes is fixable; an acute issue. The discourse is that AI causes chronic strain.

But like... the same people will watch 2-3 hours of HD Netflix or post on TikTok right after lodging their complaints on Reddit. The MW/h of AI isn't that big compared to these services. And the carbon sync of digital goods, including data centres, pales in comparison to the supply chain of Blockbuster. Nobody gave af then.

The reason they're cherry picking AI is because we're all sick of seeing tech billionaires thrive when everyone else is pressed by inflation and stagnant job markets.

Noise is a design choice and could likely be legislated away. Reject heat is different than heating from greenhouse gas effects that are “heating the planet”. No one bats an eye when an air conditioner runs.

> No one bats an eye when an air conditioner runs. In the US

Now do heat pumps in the winter.
