Every single AI data center is a toxic investment, with most of its value tied up in GPUs that will be multiple generations behind by the time these things turn on - and then die in 3-5 years.

All to build for AI demand that doesn't exist.

Actually, wait - how long do GPUs last, exactly? Four years for training? Three years? The A100 GPU started shipping in May 2020, and the H100 (and the Hopper GPU generation) entered full production in September 2022, meaning that we’re hurtling at speed toward the time in which we’re going to start seeing a remarkable amount of chips start wearing down, which should be a concern for companies like Microsoft, who bought 150,000 Hopper GPUs in 2023 and 485,000 of them in 2024.
Alright, let me just be blunt: the entire economy of debt around GPUs is insane.
Assuming these things don’t die within five years (their warranties generally end in three), their value absolutely will, as NVIDIA has committed to releasing a new AI chip every single year, likely with significant increases to power and power efficiency. At the end of the five year period, the Special Purpose Vehicle will be the proud owner of five-year-old chips that nobody is going to want to rent at the price that Elon Musk has been paying for the last five years. Don’t believe me? Take a look at the rental prices for H100 GPUs that went from $8-an-hour in 2023 to $2-an-hour in 2024, or the Silicon Data Indexes (aggregated realtime indexes of hourly prices) that show H100 rentals at around $2.14-an-hour and A100 rentals at a dollar-an-hour, with Vast.AI offering them at as little as $0.67 an hour.
This is, by the way, a problem that faces literally every data center being built in the world, and I feel insane talking about it. It feels like nobody is talking about how impossible and ridiculous all of this is - it’s one thing that OpenAI has promised one trillion dollars to people - it’s another that large swaths of that will be spent on hardware that will, by the end of these agreements, be half-obsolete and generating less revenue than ever.
Think about it - let’s assume we live in a fantasy land where OpenAI is somehow able to pay Oracle $300 billion over 5 years. Said money is paying for access to Blackwell…

It’s extraordinary that Biden’s main weaknesses were inflation and cognitive decline and now America has inflation and cognitive decline as well as tariffs, authoritarianism, blatant corruption, etc

nobody has ever lived more rent free in someone's head than Greta Thunberg, a 22 year old activist who has taken up residence in Peter Thiel's mind palace to such an extent that he thinks he needs all $400 billion of Elon Musk's notional wealth to constrain her

📊 In almost every Brazilian state, over 50% of workers will now be tax-exempt. In São Paulo: 67%. In Maranhão: a stunning 95%. Only the Federal District falls short of the halfway mark. It’s a massive shift toward income justice.
Infographic map of Brazil titled “População do Brasil com Renda de até R$ 5.000” ("Brazilian Population with Income up to R$5,000"). The map shows the percentage of the employed population in each Brazilian state (UF) earning up to R$5,000 per month (~USD 1,000), based on projections for 2025. States are color-coded in a gradient from dark blue (higher percentages) to light green (lower percentages). A note on the right explains that with an average real income of R$3,477, an estimated 84% of Brazilians fall under the R$5,000/month threshold, totaling around 85.9 million people — all potentially exempt from income tax under the new Lula-Haddad reform.

Regional highlights:

North Region (Norte): Most states above 85%. Amazonas (AM) at 90.7%, Pará (PA) at 87.2%.

Northeast (Nordeste): Highest exemption rates. Piauí (PI) leads with 94.8%, followed by Ceará (93.1%), Paraíba (93.2%), and overall regional average of 91.4%.

Southeast (Sudeste): São Paulo (SP) has the lowest at 67.5%, followed by Rio de Janeiro (RJ) at 69.8%, Minas Gerais (MG) at 81.9%. Regional average is 72.3%.

South (Sul): Rio Grande do Sul (RS) at 72.4%, Santa Catarina (SC) at 68.2%, Paraná (PR) at 71.9%.

Center-West (Centro-Oeste): Distrito Federal (DF) is the only state below 50%, at 48.1%. Other states range from 68.6% to 83.2%.

Bottom section includes:

National average: 84%

National median: 84.1%

Data source: Brasil em Mapas, based on IBGE/PNAD-C data from Q2 2025 and modeled via log-normal distribution.

In the bottom right corner, a small cartoon shows a man checking a tax form next to a large green “TAX” sign, a calculator, and a pencil, representing the tax exemption theme.

This visualization emphasizes how the vast majority of Brazilian workers—especially in poorer regions—stand to benefit from the new income tax exemption policy, which targets those earning up to R$5,000 per month.

“One of the negative consequences AI is having on students is that it is hurting their ability to develop meaningful relationships with teachers, the report finds. Half of the students agree that using AI in class makes them feel less connected to their teachers.”

Me reading another article uncritically stating that “90% of US farms are small farms & approximately 99% of them are family farms”.
- Many small farms are residential operations often used to reduce taxes;
- Family farms can be owned by individuals or corporations, the term is meaningless.

Everybody makes money out of academic authors except the authors...News.

Wiley is the latest academic publisher to reach a multi-million deal to allow access to its content to AI developers, with no opt out, let alone payment, for the authors who created that content.

The US publisher is the latest to capitalise on deals to give tech firms access to its authors’ content to train their Large Language Models (LLMs).

by the way, all those benign AI bots crawling the internet for for-profit LLMs, yeah it turns out when 9,000 hit your archive catalogue or image database all at once they break the system. This is an emerging sector issue.

The last weeks have literally seen humans labouring to feed the machines...

The Trump administration’s tariff regime and the elimination of fee exemptions for items under $800 is limiting resource sharing between university libraries, trapping some books in foreign countries, and reversing long-held standards in academic cooperation.

This story is completely insane. After our first article, Flock and the police have aggressively asserted that the woman "was never under criminal investigation by Johnson County." Flock has used it as an example of "clickbait journalism" and its CEO has attacked the reporting multiple times

The new Wiley journal review system is an absolute nightmare. Editorial assistants have been replaced by a clunky, AI-enabled website that makes it harder to find and invite reviewers. Associate editor workloads have increased. I'm not convinced the invitations to reviewers are even going through.

A baby has died of whooping cough in Mississippi amidst their worst pertussis outbreak in more than a decade.

If you have a loved one with an infant or are near babies a lot, please consider getting a pertussis booster, as is recommended by legitimate science and healthcare professionals.

From the @icpsr.bsky.social side I have to say that this was a massive lift that would not have been possible without a few incredible folks at USAID (who were RIF'd) and @datafirst.bsky.social. Many thanks to @datarescueproject.org too! It was a pleasure working with you all to preserve these data!

Good news today! All USAID-funded education data - almost 1,000 datasets - have been rescued! We helped out with a hackathon, but big shout out to @icpsr.bsky.social and @datafirst.bsky.social for all of their efforts!

This a fantastic @callingbullshit.bsky.social example.

Now you'd need basically 100% of people who have ever even briefly used ChatGPT to have had a prolonged romantic relationship with it.

Man, I'm sorry, but reading all these AI generated essays from students, it just sucks all the joy out of everything. It's exhausting, makes you into a weird paranoid cop, grinds you down, wastes your time, makes you feel like shit about everything.

Fuck this shit technology and all its enablers.
