the rather uninformed question I had: but answered in comments below

was why not solar ? Yeah Hydrocarbons have no competition if you have to deploy power quickly

1.2GW is a small turbine - compared to the land & battery needed for Solar.

how about Gas ? if you're building in the middle of nowhere ? & there's no gas lines ?

Statistics are not a license to assume. Crime rates also statistically correlate with demographics, but if I assume a specific person is a criminal based on that stat, I would (rightly) be called racist. Expecting people to assume 'historically black' == 'poor' similarly feels racist.

"Historically black" is a euphemism -- that's a term that makes people feel better about something awful -- which refers to the fact that for the majority of the last three hundred years people have been systematically, governmentally, socially and personally discriminated against because of the color of their skin, and that racism led to massive inequity reflected in wealth, income, education and standards of living.

The facts of history show this. It is not a subtle statistical effect.

People who argue the way that you have been are either woefully ignorant of this matter or are playing games trying to justify the status quo, or are just racist trolls. This isn't a FAQ on HN because it's a FAQ in real life.

If you just paid a jillion dollars for a shiny new AI datacenter, would you be ok with just running it during the day?

TFA said it's all legal and explicit federal policy. You don't have to like it, but some people are going to have to make minor sacrifices if the majority want AI services. Look on the bright side, when these people all have personal robot doctors caring for them well into their 100s they will be grateful they didn't listen to the NIMBYs

I honestly cannot tell if this is satire. Literally a Lord Farquaad level take. Some of you may get asthma and lung cancer, but that’s a sacrifice we’re willing to make to ensure we can deliver MechaHitler to the masses.

Who said anything about a specific person? They are talking about a neighborhood, in a urban area in a region known for the endemic poverty in black-majority areas due to the long shadow of slavery and Jim Crow.

As a wise character once said, "poverty is a condition, not a crime".

There are a few historically black communities in the US that are middle-class and prosperous, and Black Americans have made huge advances, but to this day, concentrations of Black American community prosperity tend to be the exception rather than the rule.

These "gas turbines" are located next door to the Allen Combined Cycle Plant, a grid scale natural gas power plant with 1.1GW capacity. It's there to power a nearby steel mill. That's the kind of neighborhood xAI has put its cluster in. I'm incredibly skeptical of any claim that xAI's power use is putting a dent in the local environment, and "environmental racism" just reeks of the usual agenda pushing.

How tall are the stacks at the combined cycle plant compared to the ones at the xAI datacenter?

My interpretation is it would be less likely to happen near a wealthy neighborhood compared to a poor neighborhood. Why talk about race if its not about race?

Who said they were poor?

Tulsa used to have a rich Black neighborhood.

The phrasing 'historically black neighborhoods' feels like it pushes a specific agenda rather than just addressing the pollution. It implies that if this were happening near a non black neighborhood, it wouldn’t be as egregious, which is a strange moral stance. Also 'historically' is irrelevant. Pollution hurts the people living there now.

It's because in the US historically black neighborhoods have a unique history of racism and disinvestment.

Here's an article about what happened literally where I'm sitting: https://kingneighborhood.org/wp-content/uploads/2015/03/BLEE...

Stories like this played all all over the US. Read up on Robert Moses for example.

Not that you intended it, but your comment veers close to the sort of "why do black people always talk about racism" thought ending cliche or similar demands to be "colorblind" that ultimately are only functionally used to shut down conversations about extant and continuing racism.

try to calculate 12312312.123213 * 123123.3123123 A computer uses orders of magnitude less energy than a human. It's all about the task, humans are specialized too. EDIT: maybe add a logarithm or other non-linear functions to make the gap even bigger.

GenAI completely fails to even get the right answer to numeric problems

Not with tool calling?

I think this is an uncharitable interpretation.

Because it is about race.

Please read the article I linked in another reply to you.

My neighborhood was prosperous when it was systematically stolen from the black people who built it. They literally razed a thriving business district. And then the land sat empty for decades, only in the end to be sold to property developers.

They used eminent domain to steal people's homes and businesses in a way that was blatantly criminal, but the victims had no recourse given the courts and entire rest of the political structure was complicit in the actions.

And variations of this story played out everywhere across America.

So yes, the fact that a neighborhood is historically black is relevant, because it shows the events of today are part of a continued arc of injustice.
