A global shortage of jet engines is threatening the rapid expansion of AI data centers, as hyperscalers like OpenAI and Amazon scramble to secure aeroderivative turbines to power their energy-hungry AI clusters. With wait times stretching into the 2030s and emissions rising, the AI boom is literally running on jet fuel. Tom’s Hardware reports: Interviews and market research indicate that manufacturers are quoting years-long lead times for turbine orders. Many of those placed today are being slotted for 2028-30, and customers are increasingly entering reservation agreements or putting down substantial deposits to hold future manufacturing capacity. “I would expect by the end of the summer, we will be largely sold out through the end of ’28 with this equipment,” said Scott Strazik, CEO of turbine maker GE Vernova, in an interview with Bloomberg back in March.

General Electric’s LM6000 and LM2500 series — both derived from the CF6 jet engine family — have quickly become the default choice for AI developers looking to spin up serious power in a hurry. OpenAI’s infrastructure partner, Crusoe Energy, recently ordered 29 LM2500XPRESS units to supply roughly one gigawatt of temporary generation for Stargate, effectively creating a mobile jet-fueled grid inside a West Texas field. Meanwhile, ProEnergy, which retrofits used CF6-80C2 engines into trailer-mounted 48-megawatt units, confirmed that it has delivered more than 1 gigawatt of its PE6000 systems to just two data center clients. These engines, which were once strapped to Boeing 767s, now spend their lives keeping inference moving.

Siemens Energy said this year that more than 60% of its US gas turbine orders are now linked to AI data centers. In some states, like Ohio and Georgia, regulators are approving multi-gigawatt gas buildouts tied directly to hyperscale footprints. That includes full pipeline builds and multi-phase interconnects designed around private-generation campuses. But the surge in orders has collided with the cold reality of turbine manufacturing timelines. GE Vernova is currently quoting 2028 or later for new industrial units, while Mitsubishi warns new turbine blocks ordered now may not ship until the 2030s. One developer reportedly paid $25 million just to reserve a future delivery slot.

Amazon said on Tuesday it would reduce its corporate workforce by approximately 14,000 roles as part of an effort to remove bureaucracy and organizational layers. Beth Galetti, the company’s senior vice president of people experience and technology, told employees in a memo that the cuts followed earlier work to strengthen teams by reducing layers and increasing ownership.

The company said it would offer most affected employees 90 days to find new roles internally and that recruiting teams would prioritize internal candidates. Those unable to find positions at Amazon will receive severance pay, outplacement services and health insurance benefits, the memo added.

ExxonMobil has sued California, claiming the state’s new climate disclosure laws violate its First Amendment rights by forcing the company to report greenhouse gas emissions and climate risks using standards it “fundamentally disagrees with.” The Verge reports: The oil and gas company claims that the two laws in question aim to “embarrass” large corporations the state “believes are uniquely responsible for climate change” in order to push them to reduce their greenhouse gas emissions. There is overwhelming scientific consensus that greenhouse gas emissions from fossil fuels cause climate change by trapping heat on the planet. […] Under laws the state passed in 2023, “ExxonMobil will be forced to describe its emissions and climate-related risks in terms the company fundamentally disagrees with,” a complaint filed Friday says. The suit asks a US District Court to stop the laws from being enforced.

[…] ExxonMobil’s latest suit now says the company “understands the very real risks associated with climate change and supports continued efforts to address those risks,” but that California’s laws would force it “to describe its emissions and climate-related risks in terms the company fundamentally disagrees with.” “These laws are about transparency. ExxonMobil might want to continue keeping the public in the dark, but we’re ready to litigate vigorously in court to ensure the public’s access to these important facts,” Christine Lee, a spokesperson for the California Department of Justice, said in an email to The Verge.

An anonymous reader quotes a report from TechCrunch: OpenAI released new data on Monday illustrating how many of ChatGPT’s users are struggling with mental health issues and talking to the AI chatbot about it. The company says that 0.15% of ChatGPT’s active users in a given week have “conversations that include explicit indicators of potential suicidal planning or intent.” Given that ChatGPT has more than 800 million weekly active users, that translates to more than a million people a week.

The company says a similar percentage of users show “heightened levels of emotional attachment to ChatGPT,” and that hundreds of thousands of people show signs of psychosis or mania in their weekly conversations with the AI chatbot. OpenAI says these types of conversations in ChatGPT are “extremely rare,” and thus difficult to measure. That said, the company estimates these issues affect hundreds of thousands of people every week. OpenAI shared the information as part of a broader announcement about its recent efforts to improve how models respond to users with mental health issues.

NextEra Energy and Google have partnered to restart Iowa’s long-shuttered Duane Arnold nuclear plant, marking the first major U.S. attempt to revive a decommissioned reactor. “We expect Duane Arnold to be back online in early 2029, and the plant will provide more than 600 MW of clean, safe, ‘always-on’ nuclear energy to the regional grid,” said Google in a blog post. Reuters reports: Under the 25-year agreement, the tech giant will purchase power from the 615-MW plant for its growing cloud and AI infrastructure in the state, while also driving significant economic investment to the Midwest region. One of the plant’s minority owners, Central Iowa Power Cooperative (CIPCO), will purchase the remaining portion of the plant’s output on the same terms as Google, NextEra said. The utility added that it had also signed agreements to acquire CIPCO and Corn Belt Power Cooperative’s combined 30% interest in the Duane Arnold plant, bringing NextEra’s ownership to 100%.

A new study from the Complexity Science Hub Vienna finds that as people’s close social circles expanded from two to five friends around the rise of social media (2008-2010), polarization in society spiked. “The connection between these two developments could provide a fundamental explanation for why societies around the world are increasingly fragmenting into ideological bubbles,” reports Phys.org. From the report: The researchers’ findings confirm that increasing polarization is not merely perceived — it is measurable and objectively occurring. “And this increase happened suddenly, between 2008 and 2010,” says [says Stefan Thurner from the Complexity Science Hub (CSH)]. The question remained: what caused it? […] The sharp rise in both polarization and the number of close friends occurred between 2008 and 2010 — precisely when social media platforms and smartphones first achieved widespread adoption. This technological shift may have fundamentally changed how people connect with each other, indirectly promoting polarization.

“Democracy depends on all parts of society being involved in decision-making, which requires that everyone be able to communicate with each other. But when groups can no longer talk to each other, this democratic process breaks down,” emphasizes Stefan Thurner. Tolerance plays a central role. “If I have two friends, I do everything I can to keep them — I am very tolerant towards them. But if I have five and things become difficult with one of them, it’s easier to end that friendship because I still have ‘backups.’ I no longer need to be as tolerant,” explains Thurner.

What disappears as a result is a societal baseline of tolerance — a development that could contribute to the long-term erosion of democratic structures. To prevent societies from increasingly fragmenting, Thurner emphasizes the importance of learning early how to engage with different opinions and actively cultivating tolerance. The research was published in Proceedings of the National Academy of Sciences.

Because yesterday it was September and I blinked and Halloween is four days away, these are a couple videos of musician Jer of Youtube channel Ska Tune Network performing all the instruments (including plenty of brass) for ska covers of the Ghostbusters and Addams Family themes. *licking fingers* Those were some tasty jams. “What was on your fingers?” Would you believe me if I told you it was actually tasty jam? “Not at all.” It was cat treat dust.

BrianFagioli shares a report from NERDS.xyz: Mozilla is testing a new Firefox feature that delivers direct results inside the address bar instead of forcing users through a search results page. The company says the feature will use a privacy framework called Oblivious HTTP, encrypting queries so that no single party can see both what you type and who you are. Some results could be sponsored, but Mozilla insists neither it nor advertisers will know user identities. The system is starting in the U.S. and may expand later if performance and privacy benchmarks are met. Further reading: Mozilla to Require Data-Collection Disclosure in All New Firefox Extensions
