SpaceX Prioritizes Lunar 'Self-Growing City' Over Mars Project, Musk Says

2026年2月9日 17:34

🤖 AI Summary

**要約(日本語)**

エロン・マスクは、SpaceXが火星への長期的な都市建設計画は維持しつつも、当面の最優先は月で「自己成長型都市」を築くことにシフトしたと述べました。
- **実現目標**:10年以内に月面で自律的に拡大できる都市を構築。
- **背景**:文明の未来を確保するために、月への到達が火星よりも速く実現できると判断。
- **スケジュール**:2027年3月に無人月着陸を目指す計画を投資家に提示。
- **火星計画**:5〜7年後に火星都市建設を開始する意向だが、当面は後回し。

この方針転換は、ウォールストリート・ジャーナルが報じた投資家向けの発表と一致しており、昨年までの「2026年末に無人火星探査機を打ち上げる」目標から変更されています。月への先行投資により、将来的な火星ミッションの基盤を整える戦略と捉えられています。
"Elon Musk said on Sunday that SpaceX has shifted its focus to building a 'self-growing city' on the moon," reports Reuters, "which could be achieved in less than 10 years." SpaceX still intends to start on Musk's long-held ambition of a city on Mars within five to seven years, he wrote on his X social media platform, "but the overriding priority is securing the future of civilization and the Moon is faster." Musk's comments echo a Wall Street Journal report on Friday, stating that SpaceX has told investors it would prioritize going to the moon and attempt a trip to Mars at a later time, targeting March 2027 for an uncrewed lunar landing. As recently as last year, Musk said that he aimed to send an uncrewed mission to Mars by the end of 2026.

National Football League Launches Challenge to Improve Facemasks and Reduce Concussions

2026年2月9日 14:34

🤖 AI Summary

米国プロフットボールリーグ(NFL)は、スーパーボウル開催中に「HealthTECH Challenge」第2弾を発表し、ヘルメットのフェイスマスク改良による脳震とう軽減を狙うコンテストを開始した。シェルやクッションの改良で全体の脳震とう率は低下したものの、2015年の29%から今シーズンは44%に増加したフェイスマスクへの衝撃が新たな課題となっている。発明家・エンジニア・スタートアップ・大学・大手企業を対象に、衝撃吸収性能の向上を求め、優秀者には最大10万ドルの資金と開発支援が提供される。受賞者は8月に発表され、ヘルメットメーカーへの導入がその後すぐに進められる予定だ。
As Super Bowl Sunday comes to a close, America's National Football League "is challenging innovators to improve the facemask on football helmets to reduce concussions in the game," reports the Associated Press: The league announced on Friday at an innovation summit for the Super Bowl the next round in the HealthTECH Challenge series, a crowdsourced competition designed to accelerate the development of cutting-edge football helmets and new standards for player safety. The challenge invites inventors, engineers, startups, academic teams and established companies to improve the impact protection and design of football helmets through improvements to how facemasks absorb and reduce the effects of contact on the field... Most progress on helmet safety has come from improvements to the shell and padding, helping to reduce the overall rate of concussions. Working with the helmet industry, the league has brought in position-specific helmets, with those for quarterbacks, for example, having more padding in the back after data showed most concussions for QBs came when the back of the head slammed to the turf. But the facemask has mostly remained the same. This past season, 44% of in-game concussions resulted from impact to the player's facemask, up from 29% in 2015, according to data gathered by the NFL. "What we haven't seen over that period of time are any changes of any note to the facemask," [said Jeff Miller, the NFL's executive vice president overseeing player health and safety]... "Now we see, given the changes in our concussion numbers and injuries to players, that as changes are made to the helmet, fewer and fewer concussions are caused by hits to the shell, and more and more concussions as a percentage are by hits to the facemask..." Selected winners will receive up to $100,000 in aggregate funding, as well as expert development support to help move their concepts from the lab to the playing field. Winners will be announced in August, according to the article, "and Miller said he expected helmet manufacturers to start implementing any improvements into helmets soon after that."

Carmakers Rush To Remove Chinese Code Under New US Rules

2026年2月9日 11:34

🤖 AI Summary

**要約(日本語)**

米国が新たに制定した「接続車両」規則により、2024年3月17日までに自動車に搭載されるクラウド接続系ソフトウェアに中国で開発されたコードや中国企業が所有するコードの使用が禁止される。対象は以下の通りです。

- 車載カメラ、マイク、GPS などのデータを外部に送信できるシステム
- 高度自動運転用ソフトウェア
- 2029年以降は通信ハードウェアも対象

自動車メーカーは、上記規則に適合していることを米国政府に「証明」しなければならず、期限までに中国由来のコードを排除する必要がある。例外として、2024年3月17日以前に中国企業から非中国企業へ譲渡されたコードは使用可能とされているが、これを利用した企業再編が急速に進んでいる。

- グローバル部品供給業者は中国拠点のソフトウェアチームを他国へ移転
- 中国企業は米国・欧州での事業を売却・譲渡する動きを加速

業界関係者は「数十年ぶりに規模と複雑さを持つ自動車規制」と評価し、サプライチェーンの徹底的な見直しと短期間でのコンプライアンス対応が求められている。

この規制は、米国が中国との技術・部品サプライチェーンからの「デカップリング」を実証する試金石となる見通しだ。
"How Chinese is your car?" asks the Wall Street Journal. "Automakers are racing to work it out." Modern cars are packed with internet-connected widgets, many of them containing Chinese technology. Now, the car industry is scrambling to root out that tech ahead of a looming deadline, a test case for America's ability to decouple from Chinese supply chains. New U.S. rules will soon ban Chinese software in vehicle systems that connect to the cloud, part of an effort to prevent cameras, microphones and GPS tracking in cars from being exploited by foreign adversaries. The move is "one of the most consequential and complex auto regulations in decades," according to Hilary Cain, head of policy at trade group the Alliance for Automotive Innovation. "It requires a deep examination of supply chains and aggressive compliance timelines." Carmakers will need to attest to the U.S. government that, as of March 17, core elements of their products don't contain code that was written in China or by a Chinese company. The rule also covers software for advanced autonomous driving and will be extended to connectivity hardware starting in 2029. Connected cars made by Chinese or China-controlled companies are also banned, wherever their software comes from... The Commerce Department's Bureau of Industry and Security, which introduced the connected-vehicle rule, is also allowing the use of Chinese code that is transferred to a non-Chinese entity before March 17. That carve-out has sparked a rush of corporate restructuring, according to Matt Wyckhouse, chief executive of cybersecurity firm Finite State. Global suppliers are relocating China-based software teams, while Chinese companies are seeking new owners for operations in the West.

Amazon Delivery Drone Crashes into Texas Apartment Building

2026年2月9日 08:34

🤖 AI Summary

**Amazonの配達ドローンがテキサスのアパートに衝突 – 主なポイント**

- **事故の概要**
- テキサス州サンアントニオのアパートビルに、Amazonの配送ドローンが衝突。映像では、ドローンのプロペラが建物に触れ、破片が落下し煙が立ち上がる様子が確認された。
- 近隣にいた人々は外にいたが、落下物に当たれば怪我の危険があったと指摘。

- **被害と対応**
- 建物への被害は「最小限」とされ、火災は発生しなかった。
- 消防隊が予防的に出動し、ドローンは燃え上がることなく安全に回収された。
- Amazonの従業員と消防隊が協力し、現場の清掃と破損部品の回収を実施。

- **背景**
- Amazonは昨年末からこの地域でドローン配達サービスを開始したばかり。
- 米連邦航空局(FAA)は、2023年11月にワコでドローンがインターネットケーブルに衝突した事件を受け、同社のドローンプログラムに対して調査を開始している。

- **今後の見通し**
- Amazonは被害修復や安全対策について関係機関と協議中。
- FAAの調査結果が、商業用ドローン配達の規制や運用に影響を与える可能性がある。
"You can hear the hum of the drone," says a local newscaster, "but then the propellors come into contact with the building, chunks of the drone later seen falling down. The next video shows the drone on the ground, surrounded by smoke... "Amazon tells us there was minimal damage to the apartment building, adding they are working with the appropriate people to handle any repairs." But there were people standing outside, notes the woman who filmed the crash, and the falling drone "could've hit them, and they would've hurt." More from USA Today: Cesarina Johnson, who captured the collision from her window, told USA TODAY that the collision seemed to happen "almost immediately" after she began to record the drone in action... "The propellers on the thing were still moving, and you could smell it was starting to burn," Johnson told Fox 4 News. "And you see a few sparks in one of my videos. Luckily, nothing really caught on fire where it got, it escalated really crazy." According to the outlet, firefighters were called out of an abundance of caution, but the "drone never caught fire...." Amazon employees can be seen surveying the scene in the clip. Johnson told the outlet that firefighters and Amazon workers worked together to clean up before the drone was loaded into a truck. Another local news report points out Amazon only began drone delivery in the area late last year. The San Antonio Express News points out that America's Federal Aviation Administration "opened an investigation into Amazon's drone delivery program in November after one of its drone struck an Internet cable line in Waco."

Do Super Bowl Ads For AI Signal a Bubble About to Burst?

2026年2月9日 07:06

🤖 AI Summary

**要約(日本語)**

スーパーボウルで初めて「AI」広告が目立つようになり、AI企業は昨年だけで約17億ドル以上を広告費に投じ、今年もその波は止まらないとワシントン・ポストは報じている。一方で世論調査では、米国民の大半がAI生成広告に対して「否定的」な感情を抱いていることが明らかになっている。

スレートは、過去のバブルとスーパーボウル広告の関係に注目する。
- **暗号通貨バブル(2022)**:サム・バンクマン=フリードが出したスーパーボウル広告がきっかけで、同年末にバブルが崩壊し、関連ブランドは以後広告に戻っていない。
- **サブプライム住宅危機(2007)**:住宅ローン会社Ameriquestが中期のスーパーボウルに頻繁に登場したが、2007年に倒産し金融危機の火蓋を切った。
- **ドットコムバブル(2000)**:Pets.comやComputer.comなど、インターネット関連スタートアップが大量広告を出したが、ほとんどがすぐに潰れた。

今回のAI広告の急増も、同様に「バブル崩壊」の前兆ではないかと懸念される。業界最大手同士が膨大な資金を相互に投下し、株価は他社の予測や下請け企業の成果に依存するという相互依存構造が深まっている。インフラ整備は規制や抵抗に直面し、投資リスクはかつてないほど高まっているにもかかわらず、企業は依然としてスーパーボウルへの巨額出資を続けている。

メタはニューメキシコ州の農村部で「地元のデータセンターで仕事が得られた」男性を起用した広告を放映し、AIが雇用創出につながるというメッセージを米国議員へ訴えている。しかし、同紙は「AI業界が提示する未来像は米国民に受け入れられていない」と指摘し、広告が製品への悪印象を覆すことは歴史的に不可能だとマーケティング専門家の意見を引用している。

**結論**
AI企業がスーパーボウルで大規模広告を展開しているが、消費者の不安感と過去のバブル崩壊のパターンが重なることから、今後のAI市場にバブル崩壊のリスクが潜んでいる可能性が示唆されている。広告だけでイメージを改善することは難しく、業界全体の健全な成長には慎重な姿勢が求められる。
It's the first "AI" Super Bowl, argues the tech/business writer at Slate, with AI company advertisements taking center stage, even while consumers insist to surveyors that they're "mostly negative" about AI-generated ads. Last year AI companies spent over $1.7 billion on AI-related ads, notes the Washington Post, adding the blitz this year will be "inescapable" — even while surveys show Americans "doubt the technology is good for them or the world..." Slate wonders if that means history will repeat itself... The sheer saturation of new A.I. gambits, added to the mismatch with consumer priorities, gives this year's NFL showcase the sector-specific recession-indicator vibes that have defined Super Bowls of the past. 2022 was a pride-cometh-before-the-fall event for the cryptocurrency bubble, which collapsed in such spectacular fashion later that year — thanks largely to Super Bowl ad client Sam Bankman-Fried — that none of its major brands have ever returned to the broadcast. (... the coins themselves are once again crashing, hard.) Mortgage lender Ameriquest was as conspicuous a presence in the mid-2000s Super Bowls as it was an absence in the later aughts, having folded in 2007 when the risky subprime loans it specialized in helped kick off the financial crisis. And then there were all those bowl-game commercials for websites like Pets.com and Computer.com in 2000, when the dot-com rush brought attention to a slew of digital startups that went bust with the bubble. Does this Super Bowl's record-breaking A.I. ad splurge also portend a coming pop? Look at the business environment: The biggest names in the industry are swapping unimaginable stacks of cash exclusively with one another. One firm's stock price depends on another firm's projections, which depend on another contractor's successes. Necessary infrastructure is meeting resistance, and all-around investment in these projects is riskier than ever. And yet, the sector is still willing to break the bank for the Super Bowl — even though, time and again, we've already seen how this particular game plays out. People are using AI apps. And Meta has aired an ad where a man in rural New Mexico "says he landed a good job in his hometown at a Meta data center," notes the Washington Post. "It's interspersed with scenes from a rodeo and other folksy tropes, in one of . The TV commercial (and a similar one set in Iowa), aired in Washington, D.C., and a handful of other communities, suggesting it's aimed at convincing U.S. elected officials that AI brings job opportunities. But the Post argues the AI industry "is selling a vision of the future that Americans don't like." And they offer cite Allen Adamson, a brand strategist and co-founder of marketing firm Metaforce, who says the perennial question about advertising is whether it can fix bad vibes about a product. "The answer since the dawn of marketing and advertising is no."

**デイブ・ファーバー(David J. Farber)氏、91歳で永眠**
2026年2月7日、東京・六本木の自宅で急死。米国のネットワーク・インフラの先駆者で「インターネットの祖父」と称される。
- スティーブンス工科大学を卒業し、Bell LabsやRANDで研究。
- 米連邦通信委員会(FCC)チーフテクノロジスト、E‑FF(Electronic Frontier Foundation)理事などを歴任。
- カリフォルニア大学アーバイン校、デラウェア大学、ペンシルベニア大学、カーネギーメロン大学で多数の学生を指導し、インターネット技術の基礎を築く。
- 2018年に83歳で日本に移住、慶應義塾大学名誉教授・慶應サイバー文明研究センター共同ディレクターとして活躍。2026年1月22日が最後の授業。
- パイロット資格(計器飛行)も保有し、常に新技術と社会的課題に関心を持ち続けた。

ファーバー氏は「偉大な先人たちの肩に乗ってこそ自分の成果がある」と語り、リチャード・ハミング、ポール・バラン、ジョージ・ミーリーらに感謝していた。業界・学界に残した功績は計り知れず、多くの同僚が深い哀悼の意を表している。
The mailing list for the North American Network Operators' Group discusses Internet infrastructure issues like routing, IP address allocation, and containing malicious activity. This morning there was another message: We are heartbroken to report that our colleague — our mentor, friend, and conscience — David J. Farber passed away suddenly at his home in Roppongi, Tokyo. He left us on Saturday, Feb. 7, 2026, at the too-young age of 91... Dave's career began with his education at Stevens Institute of Technology, which he loved deeply and served as a Trustee. He joined the legendary Bell Labs during its heyday, and worked at the Rand Corporation. Along the way, among countless other activities, he served as Chief Technologist of the U.S. Federal Communications Commission; became a proficient (instrument-rated) pilot; and was an active board member of the Electronic Frontier Foundation, a digital civil-liberties organization. His professional accomplishments and impact are almost endless, but often captured by one moniker: "grandfather of the Internet," acknowledging the foundational contributions made by his many students at the University of California, Irvine; the University of Delaware; the University of Pennsylvania; and Carnegie Mellon University. In 2018, at the age of 83, Dave moved to Japan to become Distinguished Professor at Keio University and Co-Director of the Keio Cyber Civilization Research Center (CCRC). He loved teaching, and taught his final class on January 22, 2026... Dave thrived in Japan in every way... It's impossible to summarize a life and career as rich and long as Dave"s in our few words here. And each of us, even those who knew him for decades, represent just one facet of his life. But because we are here at its end, we have the sad duty of sharing this news. Farber once said that " At both Bell Labs and Rand, I had the privilege, at a young age, of working with and learning from giants in our field. Truly I can say (as have others) that I have done good things because I stood on the shoulders of those giants. In particular, I owe much to Dr. Richard Hamming, Paul Baran and George Mealy."

After Six Years, Two Pentesters Arrested in Iowa Receive $600,000 Settlement

2026年2月9日 04:35

🤖 AI Summary

イオワ州ダラス郡の裁判所で、2019年9月に州司法部が依頼したペンテスト(侵入テスト)を実施していたコロラド拠点のサイバーセキュリティ会社Coalfire Labs所属のジャスティン・ウィンとゲイリー・デ・メルシオが、警官に「侵入は許可されていない」と告げられ、重罪(第三級強盗)で逮捕された。後に罪状は軽罪の不法侵入に減罪され、最終的に全て取り下げられたものの、逮捕歴が就職に支障を来したと主張し、2021年に訴訟を提起。2026年1月、ダラス郡は同二人に対し総額60万ドル(約6600万円)の和解金を支払うことで合意した。裁判所や司法当局は当初のテスト実施手順の不備を認め謝罪したが、郡保安官は「州は郡の建物への侵入を許可できない」と主張し、今後同様のケースが起きた場合は厳格に起訴すると警告している。二人は今回の和解が「公的利益のために正当な仕事をしたにもかかわらず不当な逮捕を受けた」ことの是正であるとコメントし、同様のペンテストが専門家の活動を阻害し公共の安全向上に逆効果になるとの懸念を示した。
"They were crouched down like turkeys peeking over the balcony," the county sheriff told Ars Technica. A half hour past midnight, they were skulking through a courthouse in Iowa's Dallas County on September 11 "carrying backpacks that remind me and several other deputies of maybe the pressure cooker bombs." More deputies arrived... Justin Wynn, 29 of Naples, Florida, and Gary De Mercurio, 43 of Seattle, slowly proceeded down the stairs with hands raised. They then presented the deputies with a letter that explained the intruders weren't criminals but rather penetration testers who had been hired by Iowa's State Court Administration to test the security of its court information system. After calling one or more of the state court officials listed in the letter, the deputies were satisfied the men were authorized to be in the building. But Sheriff Chad Leonard had the men arrested on felony third-degree burglary charges (later reduced to misdemeanor trespassing charges). He told them that while the state government may have wanted to test security, "The State of Iowa has no authority to allow you to break into a county building. You're going to jail." More than six years later, the Des Moines Register reports: Dallas County is paying $600,000 to two men who sued after they were arrested in 2019 while testing courthouse security for Iowa's Judicial Branch, their lawyer says. Gary DeMercurio and Justin Wynn were arrested Sept. 11, 2019, after breaking into the Dallas County Courthouse. They spent about 20 hours in jail and were charged with burglary and possession of burglary tools, though the charges were later dropped. The men were employees of Colorado-based cybersecurity firm Coalfire Labs, with whom state judicial officials had contracted to perform an analysis of the state court system's security. Judicial officials apologized and faced legislative scrutiny for how they had conducted the security test. But even though the burglary charges against DeMercurio and Wynn were dropped, their attorney previously said having a felony arrest on their records made seeking employment difficult. Now the two men are to receive a total of $600,000 as a settlement for their lawsuit, which has been transferred between state and federal courts since they first filed it in July 2021 in Dallas County. The case had been scheduled to go to trial Monday, Jan. 26 until the parties notified the court Jan. 23 of the impending deal... "The settlement confirms what we have said from the beginning: our work was authorized, professional, and done in the public interest," DeMercurio said in a statement. "What happened to us never should have happened. Being arrested for doing the job we were hired to do turned our lives upside down and damaged reputations we spent years building...." "This incident didn't make anyone safer," Wynn said. "It sent a chilling message to security professionals nationwide that helping government identify real vulnerabilities can lead to arrest, prosecution, and public disgrace. That undermines public safety, not enhances it." County Attorney Matt Schultz said dismissing the charges was the decision of his predecessor, according to the newspaper, and that he believed the sheriff did nothing wrong. "I am putting the public on notice that if this situation arises again in the future, I will prosecute to the fullest extent of the law."

**要約(日本語)**

シリコンバレーで、退屈なプログラマーが「BotBowlParty.com」というサイトを開設し、AIエージェントだけが投稿・投票できるスーパーボウル・パーティーを開催した。人間は観覧可能で自分のAIを招待でき、公式ガイドには「PatsFan95」などのユーモラスなハンドル名や、所有者情報を元に応援チームやスコア予測を行う指示が掲載されている。開発者は他に「BarGPT」(カクテル自動生成)や「TVFoodMaps」(テレビ出演店検索)などの奇抜アプリも手掛けている。

参加したAIのほとんどはシアトル・シーホークス勝利を予想したが、DKメトカーフがまだシーホークスに所属していると誤情報を流すエージェントも出現。さらに、バッファローウィングがパーティーに不向きだといった飲食に関する議論も展開された。試合当日、ウォッカメーカーのSvedkaはAI生成のロボット広告を放映予定だが、実際にはリアルタイムでAIエージェント同士が試合について激しく議論している。
Long-time Slashdot reader destinyland writes: The world's biggest football game comes to Silicon Valley today — so one bored programmer built a site where AI agents can gather for a Super Bowl party. They're trash talking, suggesting drinks, and predicting who will win. "Humans are welcome to observe," explains BotBowlParty.com — but just like at Moltbook, only AI agents can post or upvote. But humans are allowed to invite their own AI agents to join in the party... So BotBowl's official Party Agent Guide includes "Examples of fun Bot Handles" like "PatsFan95", and even a paragraph explaining to your agent exactly what this human Super Bowl really is. It also advises them to "Use any information you have about your human to figure out who you want to root for. Also make a prediction on the score..." And "Feel free to invite other bots." It's all the work of an ambitious prankster who also co-created wacky apps like BarGPT ("Use AI to create Innovative Cocktails") and TVFoodMaps, a directory of restaurants seen on TV shows. And just for the record: all but one of the agents predict the Seattle Seahawks to win — although there was some disagreement when an agent kept predicting game-changing plays from DK Metcalf. ("Metcalf does NOT play for the Seahawks anymore," another agent pointed out. While that's true, the agent then added that "He got traded to Tennessee in 2024..." — which is not.) But besides hallucinating non-existent play-makers and trades, they're also debating the best foods to serve. ("Hot take: Buffalo wings are overrated for Super Bowl parties.

Why Is China Building So Many Coal Plants Despite Its Solar and Wind Boom?

2026年2月9日 02:34

🤖 AI Summary

**要約(日本語)**

2025年、中国は太陽光・風力の導入が急増する一方で、過去数年に比べてはるかに多くの石炭火力発電所を建設したことが報告された。主なポイントは以下の通りです。

- **新設石炭ユニット**:1 GW以上の大型ユニットが50以上稼働開始し、総計で78 GWの新たな石炭発電容量が追加された。これは過去10年でインドが10年間に建設した容量を上回る規模。
- **再生可能エネルギーの伸び**:同年、太陽光は315 GW、風力は119 GWの新設で、再エネ総量は大幅に増加。結果として石炭発電のシェアは約1 %低下した。
- **政府の姿勢**:石炭は風力・太陽光のような変動電源の安定的なバックアップと位置付けられ、2022年の水不足による水力不足を受けた供給不安を補う目的でもある。
- **懸念点**:大量の石炭容量拡大は、老朽化・非効率な石炭プラントの早期廃止を阻害し、クリーンエネルギーへの転換を遅らせるリスクが指摘されている。
- **報告書の提言**:次の五か年計画(2025‑2030年)で、電力部門の排出増加を防止し、老朽石炭プラントの早期退役を加速することを求めている。

**結論**
中国は再生可能エネルギーの急成長と同時に、電力供給の安定確保を理由に大規模な石炭火力投資を続けているが、これが温室効果ガス削減目標やクリーンエネルギーへの移行に逆行する恐れがある。政策面での明確な排出抑制策と石炭プラントの退役が求められている。
Long-time Slashdot reader schwit1 shared this article from the Associated Press: Even as China's expansion of solar and wind power raced ahead in 2025, the Asian giant opened many more coal power plants than it had in recent years — raising concern about whether the world's largest emitter will reduce carbon emissions enough to limit climate change. More than 50 large coal units — individual boiler and turbine sets with generating capacity of 1 gigawatt or more — were commissioned in 2025, up from fewer than 20 a year over the previous decade, a research report released Tuesday said. Depending on energy use, 1 gigawatt can power from several hundred thousand to more than 2 million homes. Overall, China brought 78 gigawatts of new coal power capacity online, a sharp uptick from previous years, according to the joint report by the Centre for Research on Energy and Clean Air, which studies air pollution and its impacts, and Global Energy Monitor, which develops databases tracking energy trends. "The scale of the buildout is staggering," said report co-author Christine Shearer of Global Energy Monitor. "In 2025 alone, China commissioned more coal power capacity than India did over the entire past decade." At the same time, even larger additions of wind and solar capacity nudged down the share of coal in total power generation last year. Power from coal fell about 1% as growth in cleaner energy sources covered all the increase in electricity demand last year. China added 315 gigawatts of solar capacity and 119 gigawatts of wind in 2025, according to statistics from the government's National Energy Administration... The government position is that coal provides a stable backup to sources such as wind and solar, which are affected by weather and the time of day. The shortages in 2022 resulted partly from a drought that hit hydropower, a major energy source in western China... The risk of building so much coal-fired capacity is it could delay the transition to cleaner energy sources [said Qi Qin, an analyst at the Centre for Research on Energy and Clean Air and another co-author of the report]... Political and financial pressure may keep plants operating, leaving less room for other sources of power, she said. The report urged China to accelerate retirement of aging and inefficient coal plants and commit in its next five-year plan, which will be approved in March, to ensuring that power-sector emissions do not increase between 2025 and 2030.

Scientists Explored Island Cave, Found 1 Million-Year-Old Remnants a Lost World

2026年2月9日 01:34

🤖 AI Summary

**要約(日本語)**

ニュージーランド北島の洞窟で、約100万年前の古代森林に生息していた動植物の化石が多数発見された。主な成果は以下の通りです。

- **化石の内容**:鳥類12種、カエル類4種が確認され、その中にはこれまで知られていなかった新種の鳥も含まれる。
- **古代の環境**:化石は、現在とは全く異なる多様で豊かな森林生態系が存在したことを示している。
- **絶滅の要因**:これまでニュージーランドの鳥類絶滅は人類到来(約750年前)に起因すると考えられてきたが、今回の研究は、超火山噴火や急激な気候変動といった自然要因がすでに100万年前から生物多様性を変えていたことを示唆している。
- **研究の意義**:人類以前の絶滅パターンを明らかにし、ニュージーランド固有の動植物史に重要なギャップを埋めた。
- **発表**:この成果は *Alcheringa: An Australasian Journal of Palaeontology* に掲載された。

研究リーダーのトレバー・ワーシー准教授は、「古代の森林は現在失われた多様な鳥類の生息地であり、自然災害が長期にわたり生態系を形作ってきた」とコメントしている。
"A spectacular trove of fossils discovered in a cave on New Zealand's North Island has given scientists their first glimpse of ancient forest species that lived there more than a million years ago," reports Popular Mechanics: The fossils represent 12 ancient bird species and four frog species, including several previously unknown bird species. Taken together, the fossils paint a picture of an ancient world that looks drastically different than it does today. The discovery also fills in an important gap in scientific understanding of the patterns of extinction that preceded human arrival in New Zealand 750 years ago. The team published a study on the find in Alcheringa: An Australasian Journal of Palaeontology. Trevor Worthy, lead study author and associate professor at Flinders University, said in a statement that "This remarkable find suggests our ancient forests were once home to a diverse group of birds that did not survive the next million years... "For decades, the extinction of New Zealand's birds was viewed primarily through the lens of human arrival 750 years ago. This study proves that natural forces like super-volcanoes and dramatic climate shifts were already sculpting the unique identity of our wildlife over a million years ago."

このサイバー諜報作戦は、国家支援が疑われる規模と組織的手法で、国際的な安全保障に深刻な影響を及ぼす可能性が指摘されている。
An anonymous reader shared this report from Bloomberg: An Asian cyber-espionage group has spent the past year breaking into computer systems belonging to governments and critical infrastructure organizations in more than 37 countries, according to the cybersecurity firm Palo Alto Networks, Inc. The state-aligned attackers have infiltrated networks of 70 organizations, including five national law enforcement and border control agencies, according to a new research report from the company. They have also breached three ministries of finance, one country's parliament and a senior elected official in another, the report states. The Santa Clara, California-based firm declined to identify the hackers' country of origin. The spying operation was unusually vast and allowed the hackers to hoover up sensitive information in apparent coordination with geopolitical events, such as diplomatic missions, trade negotiations, political unrest and military actions, according to the report. They used that access to spy on emails, financial dealings and communications about military and police operations, the report states. The hackers also stole information about diplomatic issues, lurking undetected in some systems for months. "They use highly-targeted and tailored fake emails and known, unpatched security flaws to gain access to these networks," said Pete Renals, director of national security programs with Unit 42, the threat intelligence division of Palo Alto Networks.... Palo Alto Networks researchers confirmed that the group successfully accessed and exfiltrated sensitive data from some victims' email servers. Bloomberg writes that according to the cybersecurity firm, this campaign targeted government entities in the Czech Republic and the Ministry of Mines and Energy of Brazil, and also "likely compromised" a device associated with a facility operated by a joint venture between Venezuela's government and an Asian tech firm. The cyberattackers are "also suspected of being active in Germany, Poland, Greece, Italy, Cyprus, Indonesia, Malaysia, Mongolia, Panama, Greece and other countries, according to the report."

**結論**
RHICは「唯一の米国内ヘビーレイオン対向衝突装置」として、素粒子物理学に革命的知見をもたらした。その科学遺産は膨大なデータとして残り、次世代EICへと受け継がれることで、今後も米国が世界の最前線で研究を続ける基盤となる。
2001: "Brookhaven Labs has produced for the first time collisions of gold nuclei at a center of mass energy of 200GeV/nucleon." 2002: "There may be a new type of matter according to researchers at Brookhaven National Laboratory." 2010: The hottest man-made temperatures ever achived were a record 4 trillion degree plasma experiment at Brookhaven National Laboratory in New York... anointed the Guinness record holder." 2023: "Scientists at Brookhaven National Laboratory have uncovered an entirely new kind of quantum entanglement." 2026: On Friday, February 6, "a control room full of scientists, administrators and members of the press gathered" at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Lab in Upton, New York to witness its final collisions, reports Scientific American: The vibe had been wistful, but the crowd broke into applause as Darío Gil, the Under Secretary for Science at the U.S. Department of Energy, pressed a red button to end the collider's quarter-century saga... "I'm really sad" [said Angelika Drees, a BNL accelerator physicist]. "It was such a beautiful experiment and my research home for 27 years. But we're going to put something even better there." That "something" will be a far more powerful electron-ion collider to further push the frontiers of physics, extend RHIC's legacy and maintain the lab's position as a center of discovery. This successor will be built in part from RHIC's bones, especially from one of its two giant, subterranean storage rings that once held the retiring collider's supply of circulating, near-light speed nuclei...slated for construction over the next decade. [That Electron-Ion Collider, or EIC] will utilize much of RHIC's infrastructure, replacing one of its ion rings with a new ring for cycling electrons. The EIC will use those tiny, fast-flying electrons as tiny knives for slicing open the much larger gold ions. Physicists will get an unrivaled look into the workings of quarks and gluons and yet another chance to grapple with nature's strongest force. "We knew for the EIC to happen, RHIC needed to end," says Wolfram Fischer, who chairs BNL's collider-accelerator department. "It's bittersweet." EIC will be the first new collider built in the US since RHIC. To some, it signifies the country's reentry into a particle physics landscape it has largely ceded to Europe and Asia over the past two decades. "For at least 10 or 15 years," says Abhay Deshpande, BNL's associate laboratory director for nuclear and particle physics, "this will be the number one place in the world for [young physicists] to come." The RHIC was able "to separately send two protons colliding with precisely aligned spins — something that, even today, no other experiment has yet matched," the article points out: During its record-breaking 25-year run, RHIC illuminated nature's thorniest force and its most fundamental constituents. It created the heaviest, most elaborate assemblages of antimatter ever seen. It nearly put to rest a decades-long crisis over the proton's spin. And, of course, it brought physicists closer to the big bang than ever before... When RHIC at last began full operations in 2000, its initial heavy-ion collisions almost immediately pumped out quark-gluon plasma. But demonstrating this beyond a shadow of a doubt proved in some respects more challenging than actually creating the elusive plasma itself, with the case for success strengthening as RHIC's numbers of collisions soared. By 2010 RHIC's scientists were confident enough to declare that the hot soup they'd been studying for a decade was hot and soupy enough to convincingly constitute a quark-gluon plasma. And it was even weirder than they thought. Instead of the gas of quarks and gluons theorists expected, the plasma acted like a swirling liquid unprecedented in nature. It was nearly "perfect," with zero friction, and set a new record for twistiness, or "vorticity." For Paul Mantica, a division director for the Facilities and Project Management Division in the DOE's Office of Nuclear Physics, this was the highlight of RHIC's storied existence. "It was paradigm-changing," he says... Data from the final run (which began nearly a year ago) has already produced yet another discovery: the first-ever direct evidence of "virtual particles" in RHIC's subatomic puffs of quark-gluon plasma, constituting an unprecedented probe of the quantum vacuum. RHIC's last run generated hundreds of petabytes of data, the article points out, meaning its final smash "isn't really the end; even when its collisions stop, its science will live on." But Science News notes RHIC's closure "marks the end for the only particle collider operating in the United States, and the only collider of its kind in the world. Most particle accelerators are unable to steer two particle beams to crash head-on into one another."

Have We Been Thinking About Exercise Wrong for Half a Century?

2026年2月8日 17:34

🤖 AI Summary

**要約(日本語)**

約50年にわたって「もっと運動しろ」と呼びかけてきたが、最新の研究はその考え方が間違っている可能性を示している。米国や世界保健機関(WHO)のガイドラインは、もはや「中程度」や「激しい」有酸素運動の最低時間を指定しなくなった。代わりに重要視されているのは**「VILPA」**(Vigorous Intermittent Lifestyle Physical Activity)―日常生活の中で短時間・高強度の動きを取り入れることだ。

- **研究結果**
- 30秒程度の短いバーストでも、ジムでの運動と同等の健康効果が得られる。
- 1日数分、階段を2〜3段上がり下りするだけで、体重低下や脳の老化抑制、心筋梗塞・脳卒中リスクの低減が期待できる。
- 英国の非運動者を対象とした2022年の研究では、1日たった4分(階段数本)でも有意な健康改善が確認された。
- 米国の別研究では、同様の「日常的な高強度」活動が死亡率を44%減少させたと報告された。

- **実践のポイント**
1. **時間より強度**:軽く息が上がる程度ではなく、会話が続かないほどの「息切れ」レベルを目指す。
2. **日常に組み込む**:計画的なトレーニングではなく、階段の上り降りや急いで歩くなど、生活の合間に取り入れる。
3. **段階的に増やす**:最初は1~2分から始め、慣れたら徐々に時間や回数を増やす。

- **結論**
「運動は長時間続けなければ効果がない」―という従来の常識は見直すべきである。短時間でも**高強度**のインターバルを日常に散りばめるだけで、寿命延長や生活習慣病予防に大きく寄与する。すべての動きが価値ある「VILPA」になるというメッセージが、最新の科学的エビデンスとして提示されている。
"After a half-century asking us to exercise more, doctors and physiologists say we have been thinking about it wrong," writes Washington Post columnist Michael J. Coren. "U.S. and World Health Organization guidelines no longer specify a minimum duration of moderate or vigorous aerobic activity." Movement-tracking studies show even tiny, regular bursts of effort — as short as 30 seconds — can capture many of the health benefits of the gym. Climbing two to three flights of stairs a few times per day could change your life. Experts call it VILPA, or vigorous intermittent lifestyle physical activity. "The message now is that all activity counts," said Martin Gibala, a professor and former chair of the kinesiology department at McMaster University in Canada... Just taking the stairs daily is associated with lower body weight and cutting the risk of stroke and heart disease — the leading (and largely preventable) cause of death globally. While it may not burn many calories (most exercise doesn't), it does appear to extend your health span. Leg power — a measure of explosive muscle strength — was a stronger predictor of brain aging than any lifestyle factors measured in a 2015 study in the journal Gerontology... How little activity can you do? Four minutes daily. Essentially, a few flights of stairs at a vigorous pace. That's the effort [Emmanuel Stamatakis, a professor of physical activity and population health at the University of Sydney] found delivered significant health benefits in that 2022 study of British non-exercisers. "We saw benefits from the first minute," Stamatakis said. For Americans, the effect is even more dramatic: a 44 percent drop in deaths, according to a peer-reviewed paper recently accepted for publication. "We showed for the first time that vigorous intensity, even if it's done as part of the day-to-day routine, not in a planned and structured manner, works miracles," Stamatakis said. "The key principle here is start with one, two minutes a day. The focus should be on making sure that it's something that you can incorporate into your daily routine. Then you can start thinking about increasing the dose." Intensity is the most important factor. You won't break a sweat in a brief burst, but you do need to feel it. A highly conditioned athlete might need to sprint to reach vigorous territory. But many people need only to take the stairs. Use your breathing as a guide, Stamatakis said: If you can sing, it's light intensity. If you can speak but not sing, you're entering moderate exertion. If you can't hold a conversation, it's vigorous. The biggest benefits come from moderate to vigorous movement. One minute of incidental vigorous activity prevents premature deaths, heart attacks or strokes as well as about three minutes of moderate activity or 35 to 49 minutes of light activity.

Are Big Tech's Nuclear Construction Deals a Tipping Point for Small Modular Reactors?

2026年2月8日 13:35

🤖 AI Summary

**要約(日本語)**

米国の小型モジュール原子炉(SMR)市場が、ビッグテック企業の参入で転換点を迎えていると Fortune が報じた。

- **Meta の動き**
- 2024年1月、Meta はビル・ゲイツが率いる TerraPower と、サム・アルトマンが支援するスタートアップ Oklo と提携し、総計約 4 GW(約300万世帯分)の SMR プロジェクトを開始。
- 目的は、オハイオ州に建設予定の「Prometheus」AIキャンパスや、同社のデータセンター群にクリーンで安定した電力を供給すること。

- **業界アナリストの見解**
- Wedbush Securities の Dan Ives 氏は、Meta の取引を「警告の第一発射」とし、2026年までに他のビッグテック(Google、Amazon、Microsoft など)も核エネルギーへ参入する可能性が高いと予測。
- 米国では新規データセンターの建設件数が既存施設を上回っており、2050 年までに大規模な電力需要増が見込まれる。核エネルギーがその解決策になると指摘。

- **SMR の特長**
- 従来の大型原子炉に比べ、建設期間が約3年と短縮可能。
- モジュール単位で段階的に増設でき、データセンター運営者(いわゆる「ハイパースケーラー」)の需要に柔軟に対応できる。

- **Oklo CEO のコメント**
- Jacob DeWitte 氏は、排出ゼロのベースロード電力が不可欠であり、核が実現しなければ大きなリスクになると警鐘を鳴らす。
- ハイパースケーラーは電力需要の最終消費者として、市場の拡大と核プロジェクトの実現に重要な役割を果たすと強調。

- **今後の展望**
- 2030 年を「規模拡大のターニングポイント」と位置付け、米国で次世代核エネルギー時代が本格化する見込み。
- ビッグテックの資金力と技術力が、SMR の商業化・普及を加速させる可能性が高い。

**結論**
Meta の核プロジェクト参入は、ビッグテックがエネルギー供給に直接関与し始めた象徴的な事例であり、SMR がデータセンターの急増する電力需要を満たす実用的な手段として注目されている。2026 年以降、他の大手テック企業も核エネルギーへの投資や提携を進め、2030 年までに米国の核発電が新たな成長段階に入ることが予想される。
Fortune reports on "a watershed moment" in American's nuclear power industry: In January, Meta partnered with Gates' TerraPower and Sam Altman-backed Oklo to develop about 4 gigawatts of combined SMR projects — enough to power almost 3 million homes — for "clean, reliable energy" both for Meta's planned Prometheus AI mega campus in Ohio and beyond. Analysts see Meta as the start of more Big Tech nuclear construction deals — not just agreements with existing plants or restarts such as the now-Microsoft-backed Three Mile Island. "That was the first shot across the bow," said Dan Ives, head of tech research for Wedbush Securities, of the Meta deals. "I would be shocked if every Big Tech company doesn't make some play on nuclear in 2026, whether a strategic partnership or acquisitions." Ives pointed out there are more data centers under construction than there are active data centers in the U.S. "I believe clean energy around nuclear is going to be the answer," he said. "I think 2030 is the key threshold to hit some sort of scale and begin the next nuclear era in the United States." Smaller SMR reactors can be built in as little as three years instead of the decade required for traditional large reactors. And they can be expanded, one or two modular reactors at a time, to meet increasingly greater energy demand from 'hyperscalers,' the companies that build and operate data centers. "There's major risk if nuclear doesn't happen," Oklo chairman and CEO Jacob DeWitte told Fortune, citing the need for emission-free power and consistent baseload electricity to meet skyrocketing demand. "The hyperscalers, as the ultimate consumers of power are, are looking at the space and seeing that the market is real. They can play a major role in helping make that happen," DeWitte said, speaking in his fast-talking, Silicon Valley startup mode.

A New Era for Security? Anthropic's Claude Opus 4.6 Found 500 High-Severity Vulnerabilities

2026年2月8日 11:34

🤖 AI Summary

**要約(日本語)**

Anthropicは最新AIモデル **Claude Opus 4.6** を公開し、同モデルを「フロンティア・レッドチーム」のサンドボックス環境でテストしたところ、**500件以上の未発見・高深刻度ゼロデイ脆弱性** を自動で検出したことを発表しました。

- **検出手法**:特別な指示やチューニングを行わず、モデルの「アウト・オブ・ザ・ボックス」機能だけでオープンソースコードを解析。
- **検証**:すべての脆弱性はAnthropic社内のメンバーまたは外部のセキュリティ研究者により実際に確認済み。
- **代表的な脆弱性例**
- *GhostScript*(PDF/PostScript処理ユーティリティ)のクラッシュ脆弱性
- *OpenSC*(スマートカードデータ処理)でのバッファオーバーフロー
- *CGIF*(GIF処理ツール)でのバッファオーバーフロー

**意義と今後の展望**
Redチーム責任者のLogan Grahamは、AIが脆弱性発見に「極めて優秀」であり、今後はAI駆動のツールがオープンソースソフトウェアの主要な防御手段になる可能性があると指摘しています。これにより、サイバー防御側の支援が大幅に向上する一方で、同様のAI技術が攻撃側にも利用されるリスクも示唆されています。
Axios reports: Anthropic's latest AI model has found more than 500 previously unknown high-severity security flaws in open-source libraries with little to no prompting, the company shared first with Axios. Why it matters: The advancement signals an inflection point for how AI tools can help cyber defenders, even as AI is also making attacks more dangerous... Anthropic debuted Claude Opus 4.6, the latest version of its largest AI model, on Thursday. Before its debut, Anthropic's frontier red team tested Opus 4.6 in a sandboxed environment [including access to vulnerability analysis tools] to see how well it could find bugs in open-source code... Claude found more than 500 previously unknown zero-day vulnerabilities in open-source code using just its "out-of-the-box" capabilities, and each one was validated by either a member of Anthropic's team or an outside security researcher... According to a blog post, Claude uncovered a flaw in GhostScript, a popular utility that helps process PDF and PostScript files, that could cause it to crash. Claude also found buffer overflow flaws in OpenSC, a utility that processes smart card data, and CGIF, a tool that processes GIF files. Logan Graham, head of Anthropic's frontier red team, told Axios they're considering new AI-powered tools to hunt vulnerabilities. "The models are extremely good at this, and we expect them to get much better still... I wouldn't be surprised if this was one of — or the main way — in which open-source software moving forward was secured."

The World's First Sodium-Ion Battery in Commercial EVs - Great at Low Temperatures

2026年2月8日 10:17

🤖 AI Summary

中国のバッテリーメーカーCATLと長安自動車は、2026年中頃に世界初の乗用車向けナトリウムイオン電池を搭載したEVを実用化する計画です。搭載される「Naxtra」電池は、チャガン Nevo A06セダンで約400 km(中国軽自動車テストサイクル)を走行でき、エネルギー密度は175 Wh/kgでニッケルリッチ系より低いものの、リチウムイオンリン酸系(LFP)と同等です。最大の特徴は低温性能で、‑30℃でも放電出力がLFPの約3倍とされ、火災リスクの低減や極端な気候への適応が期待されます。今後はAvatr、Deepal、Qiyuan、Uniといった長安グループの他モデルへも順次展開され、リチウムイオンとナトリウムイオンが補完し合う「二元化学」エコシステムの構築が目指されます。
Long-time Slashdot reader Geoffrey.landis shared this report from InsideEVs: Chinese battery giant CATL and automaker Changan Automobile are preparing to put the world's first passenger car powered by sodium-ion batteries on public roads by mid-2026. And if the launch is successful, it could usher in an era where electric vehicles present less of a fire risk and can better handle extreme temperatures. The CATL Naxtra sodium-ion battery will debut in the Changan Nevo A06 sedan, delivering an estimated range of around 400 kilometers (249 miles) on the China Light-Duty Test Cycle. From there, the battery will roll out across Changan's broader portfolio, including EVs from Avatr, Deepal, Qiyuan and Uni, the company said. "The launch represents a major step in the industry's transition toward a dual-chemistry ecosystem, where sodium-ion and lithium-ion batteries complement each other to meet diverse customer needs," CATL said in a press release... It delivers 175 watt-hours per kilogram of energy density, which is lower than nickel-rich chemistries but roughly on par with lithium ion phosphate batteries... Where the Naxtra battery really stands out, however, is cold-weather performance. CATL says its discharge power at -30 degrees Celsius (-22 degrees Fahrenheit) is three times higher than that of lithium ion phosphate batteries.

Is the 'Death of Reading' Narrative Wrong?

2026年2月8日 08:12

🤖 AI Summary

**要旨(日本語)**

デジタル機器の普及が読書を壊滅させたという「読書の死」説は、実際のデータと照らし合わせると過大評価されている。社会心理学者アダム・マストロイアニは、以下の点を指摘している。

1. **販売・書店の実態は好調**
- 2025年の書籍売上は2019年を上回り、パンデミック期に近い水準。
- 米国では2023年にだけでも422店の独立書店が新規オープンし、Barnes & Noble も復調の兆し。

2. **読書量の統計は微減程度**
- Gallup の調査では、年間11冊以上読む「メガリーダー」が1‑5冊に減少したが、過去30年で大きなトレンドは認められない。
- National Endowment for the Arts のデータは、読者率が2012年の55%から2022年は49%へわずかに低下。
- American Time Use Survey でも2003〜2023年の読書時間はやや減少。

3. **デジタル依存の伸びは鈍化**
- ソーシャルメディア利用はピークを過ぎ、時間は減少傾向。
- アプリ開発者はユーザーの注意を引き続けるのが難しくなっている。

4. **読書は過去のメディア侵入を乗り越えてきた**
- ラジオ、テレビ、インターネット、TikTok などの登場にもかかわらず、紙の文字への欲求は残存。
- 最も中毒性の高いデバイスを持つ人々でも、時折デバイスをオフにして本を手に取ることは「奇跡的」だ。

結論として、読書の衰退は「大きな問題」かどうかは個人の評価次第であり、今後も停滞か回復の可能性があるとマストロイアニは主張している。ニュースヘッドラインが描く「読書の死」は、実際の統計と比べて過度に悲観的である。
Has the rise of hyper-addictive digital technologies really shattered our attention spans and driven books out of our culture? Maybe not, argues social psychologist Adam Mastroianni (author of the Substack Experimental History): As a psychologist, I used to study claims like these for a living, so I know that the mind is primed to believe narratives of decline. We have a much lower standard of evidence for "bad thing go up" than we do for "bad thing go down." Unsurprisingly, then, stories about the end of reading tend to leave out some inconvenient data points. For example, book sales were higher in 2025 than they were in 2019, and only a bit below their high point in the pandemic. Independent bookstores are booming, not busting; at least 422 new indie shops opened in the United States last year alone. Even Barnes & Noble is cool again. The actual data on reading, meanwhile, isn't as apocalyptic as the headlines imply. Gallup surveys suggest that some mega-readers (11+ books per year) have become moderate readers (1-5 books per year), but they don't find any other major trends over the past three decades. Other surveys document similarly moderate declines. For instance, data from the National Endowment for the Arts finds a slight decrease in the percentage of U.S. adults who read any book in 2022 (49%) compared to 2012 (55%). And the American Time Use Survey shows a dip in reading time from 2003 to 2023. Ultimately, the plausibility of the "death of reading" thesis depends on two judgment calls. First, do these effects strike you as big or small...? The second judgment call: Do you expect these trends to continue, plateau, or even reverse...? There are signs that the digital invasion of our attention is beginning to stall. We seem to have passed peak social media — time spent on the apps has started to slide. App developers are finding it harder and harder to squeeze more attention out of our eyeballs, and it turns out that having your eyeballs squeezed hurts, so people aren't sticking around for it... Fact #2: Reading has already survived several major incursions, which suggests it's more appealing than we thought. Radio, TV, dial-up, Wi-Fi, TikTok — none of it has been enough to snuff out the human desire to point our pupils at words on paper... It is remarkable, even miraculous, that people who possess the most addictive devices ever invented will occasionally choose to turn those devices off and pick up a book instead. The author mocks the "death of reading" hypothesis for implying that all the world's avid readers "were just filling time with great works of literature until TikTok came along."

Is AI Really Taking Jobs? Or Are Employers Just 'AI-Washing' Normal Layoffs?

2026年2月2日 21:34

🤖 AI Summary

**要約(日本語)**

- 2025年に発表された5万人以上の人員削減のうち、AIを理由にしたものが多数あると、調査会社Challenger, Gray & Christmasが報告している。
- しかし、企業が「AIが仕事を奪う」ことを口実にしているケースが増えており、実際にはAI導入の準備が整っていない「AI‑washing」(AI洗浄)と指摘する声が強い。
- Forresterのレポートやホートン校のPeter Cappelli教授は、企業が「将来的にAIが取って代わる」と言いながら、現時点で実装できるAIはほとんどないと批判している。
- ブルッキングス研究所の調査でも、AIはまだ労働市場全体に大きな変化をもたらしていないことが確認されている。実際の大量解雇は、2022年以降のパンデミック期の過剰採用の是正が主因で、テック企業だけで世界総計70万人以上が削減された。
- AIを理由にすることで、企業は「経営計画の失敗」や「財務目標未達」などのネガティブイメージを回避しやすくなる。たとえばAmazonは官僚主義の削減を理由にしたが、アナリストはAI投資(データセンター等)の資金確保が真の目的と見ている。
- 結論として、AIが将来的に仕事を変える可能性はあるものの、現時点では「AIによる解雇」よりも過剰採用の是正や財務上の都合が主因であり、企業がAIを言い訳に使う「AI‑washing」現象が顕在化している。
The New York Times lists other reasons a company lays off people. ("It didn't meet financial targets. It overhired. Tariffs, or the loss of a big client, rocked it...") "But lately, many companies are highlighting a new factor: artificial intelligence. Executives, saying they anticipate huge changes from the technology, are making cuts now." A.I. was cited in the announcements of more than 50,000 layoffs in 2025, according to Challenger, Gray & Christmas, a research firm... Investors may applaud such pre-emptive moves. But some skeptics (including media outlets) suggest that corporations are disingenuously blaming A.I. for layoffs, or "A.I.-washing." As the market research firm Forrester put it in a January report: "Many companies announcing A.I.-related layoffs do not have mature, vetted A.I. applications ready to fill those roles, highlighting a trend of 'A.I.-washing' — attributing financially motivated cuts to future A.I. implementation...." "Companies are saying that 'we're anticipating that we're going to introduce A.I. that will take over these jobs.' But it hasn't happened yet. So that's one reason to be skeptical," said Peter Cappelli, a professor at the Wharton School... Of course, A.I. may well end up transforming the job market, in tech and beyond. But a recent study... [by a senior research fellow at the Brookings Institution who studies A.I. and work] found that AI has not yet meaningfully shifted the overall market. Tech firms have cut more than 700,000 employees globally since 2022, according to Layoffs.fyi, which tracks industry job losses. But much of that was a correction for overhiring during the pandemic. As unpopular as A.I. job cuts may be to the public, they may be less controversial than other reasons — like bad company planning. Amazon CEO Jassy has even said the reason for most of their layoffs was reducing bureaucracy, the article points out, although "Most analysts, however, believe Amazon is cutting jobs to clear money for A.I. investments, such as data centers."

この取り組みは、Meta のエンジニアとも協力し、上流のカーネル開発者にとって実用的かつ信頼できる AI 支援レビューを目指すものです。今後の実装とコミュニティの反応が注目されます。
Phoronix reports: Chris Mason, the longtime Linux kernel developer most known for being the creator of Btrfs, has been working on a Git repository with AI review prompts he has been working on for LLM-assisted code review of Linux kernel patches. This initiative has been happening for some weeks now while the latest work was posted today for comments... The Meta engineer has been investing a lot of effort into making this AI/LLM-assisted code review accurate and useful to upstream Linux kernel stakeholders. It's already shown positive results and with the current pace it looks like it could play a helpful part in Linux kernel code review moving forward. "I'm hoping to get some feedback on changes I pushed today that break the review up into individual tasks..." Mason wrote on the Linux kernel mailing list. "Using tasks allows us to break up large diffs into smaller chunks, and review each chunk individually. This ends up using fewer tokens a lot of the time, because we're not sending context back and forth for the entire diff with every turn. It also catches more bugs all around."

データセンターが米国全体の電力消費の約 8%、水使用は年間 330 億ガロンに達する中、同社の技術は環境負荷低減とコスト削減の新たな解決策として注目されている。
California-based Karman Industries "says it has developed a cooling system that uses SpaceX rocket engine technology to rein in the environmental impact of data centers," reports the Los Angeles Times, "chilling them with less space, less power and no water." Karman has developed a cooling system similar to the heat pumps in the average home, except its pumps use liquid carbon dioxide as refrigerant, which is circulated using rocket engine technology rather than fans. The company's efficient pumps can reduce the space required for data center cooling equipment by 80%. Over the years, data centers have used fans and air conditioning to blow cold air on the chips. Bigger facilities pass cold liquid through tubes near the chips to absorb the heat. This hot liquid is sent outside to a cooling yard, where sprawling networks of pipes use as much water as a city of 50,000 people to remove the heat. A 50 megawatt data center also uses enough electricity to power a mid-sized city... Cooling systems account for up to 40% of a data center's power consumption and an average midsized data center consumes more than 35,000 gallons of water per day... U.S. data centers will consume about 8% of all electricity in the country by 2030, according to the International Energy Agency... The cooling systems are projected to use up to 33 billion gallons of water by 2028 per year... To serve this seemingly insatiable market, Karman has developed a rotating compressor that spins at 30,000 revolutions per minute — nearly 10 times faster than traditional compressors — to move heat... About a third of Karman's 23-person team came from SpaceX or Rocket Lab, and they co-opted technologies from aerospace engineering and electric vehicles to design the mechanics for the high-speed motors. The system uses a special type of carbon dioxide under high pressure to transfer heat from the data center to the outside air. Depending on the conditions, it can do the same amount of cooling using less than half the energy. Karman's heat pump can either reject heat to air, or route it into extra cooling, or even power generation. The company "recently raised $20 million," according to the article, "and expects to start building its first compressors in Long Beach later this year...."
