Regulators Delay Approval for Boeing’s 737 MAX 10
規制当局、ボーイング737 MAX 10の承認を延期
P.M. Edition for Sept. 28. The FAA’s delay, over a software glitch that could pose a potential safety risk, sent Boeing stock sliding. Plus, top researchers from some of the biggest names in artificial intelligence published a report today asking policymakers to oversee self-improving AI systems. It’s the latest turn in the conversation over AI safety—which, as Journal tech policy reporter Amrith Ramkumar tells us, is also going on in the White House. Nvidia is launching the largest-ever U.S. stock buyback. And WSJ reporter Evan Gershkovich, who was arrested in Russia in 2023 and spent more than a year imprisoned there, reflects with editor in chief Emma Tucker on how his experience has changed him on the eve of the release of his new book. Alex Ossola hosts.

Alex Ossola: Nvidia launches the largest ever U.S. Stock buyback. Plus, more researchers call for oversight of AI, while President Trump plans to meet with tech executives tomorrow.
Amrith Ramkumar: The industry is very divided on this issue, and as a result, so is the administration. And both sides are often pointing the finger at one another.
Alex Ossola: And the FAA is delaying approval of Boeing's 737 Max 10. It's Monday, September 28. I'm Alex Ossola for The Wall Street Journal. This is the PM Edition of What's News, the top headlines and business stories that move the world today.
First on today's show, an update on the suspected terrorist plot on an air base in the UK that hosts U.S. Forces. British counterterrorism police said that they were releasing five men on bail who were arrested over the foiled attack. The five men are all U.K. Nationals in their 20s, but investigators are probing whether Iran or an Islamist group had orchestrated the plot. The five men remain under investigation and security officials suspect that U.S. B-1 bombers at the base were a likely target of the plot. Iran's embassy in the UK said today that it rejects attempts to link Iran to the arrests.
• on bail /ɑːn beɪl/ 保釈されて
• foiled attack /fɔɪld əˈtæk/ 阻止された攻撃、未遂に終わった攻撃
• orchestrate /ˈɔːrkəstreɪt/ （計画などを）仕組む、裏で指揮する
And in the U.S. a report out from Senate Democrats today says that Iran has relied on digital dollars issued by crypto company Tether to bypass U.S. sanctions. A Tether spokesman didn't return requests for comment. The company has worked with law enforcement to freeze some wallets tied to the regime.
Nvidia is launching the largest ever U.S. stock buyback. Today, the chip giant said its board had approved a $150 billion increase to its share repurchase program, bringing the total buyback authorization to $235 billion. The company is flush with cash from the AI boom. Its stock closed up 1.7%.
• be flush with cash /bi flʌʃ wɪð kæʃ/ 現金を潤沢に持っている
Separately today, Nvidia launched a software platform to help developers test AI agents in a secure environment after a number of AI agents went rogue in recent months. It's part of a broader conversation going on about AI safety. What started as a warning from some of the biggest names in artificial intelligence has become an international conversation about whether and how to regulate AI for safety. We're exclusively reporting that research leaders at OpenAI, Anthropic, Meta, and Microsoft have asked policymakers to probe the degree to which their companies have made AI research automated. In a paper published today, the researchers wrote that automating AI research could compress the work so much that humans might no longer be able to understand it, and that could prevent people from being able to catch problems with AI models or from being able to solve those problems.
• compress /kəmˈpres/ 圧縮する、短縮する
• go rogue /ɡoʊ roʊɡ/ 暴走する、制御不能になる
もともと rogue = 群れから外れた・制御できないもの というイメージから、
「組織・ルール・意図された制御から外れて勝手に行動する」
And President Trump is also weighing what AI safety regulation might look like. For more on what's going on in the White House, I'm joined now by WSJ tech policy reporter Amrith Ramkumar. Amrith, initially Trump was very dismissive of calls to regulate AI, but more recently he's promised to do things like create an AI force and recruit a new AI czar. Why did he change his tune on this?
calls to do = 「～するよう求める声」
• dismissive of /dɪˈmɪsɪv əv/ ～を軽視する、～を取り合わない
• AI czar /ˌeɪ aɪ ˈzɑːr/ AI政策の総責任者、AI担当責任者
Amrith Ramkumar: I don't think we should look at this as the President changing his tune much. He's definitely caught in two minds on AI. He is super focused on beating China in the AI race and a minimal regulatory stance essentially. But the President has spoken over the years about the risks with AI and he's said at times that there needs to be a kill switch where a human can take control of the system if it's spiraling out of control. And we know that many of his top advisors have been warning him in recent months that the risks of cyber attacks caused by AI are going up. So I think he knows he needs to show some action here. This issue is very unpopular with voters and voters want to see some action. So I think that's why you're seeing some conflicting messaging and pure chaos, frankly, in recent days.
caught in two minds /ˌkɔːt ɪn tuː ˈmaɪndz/ 意見・気持ちが二つに割れて、板挟みになって
kill switch /ˈkɪl swɪtʃ/ 緊急停止装置、緊急停止機能
spiral out of control /ˈspaɪrəl aʊt əv kənˈtroʊl/ 制御不能な状態に陥る、どんどん悪化して手に負えなくなる
pure chaos /pjʊr ˈkeɪɑːs/ 完全な混乱、まったくのカオス
Alex Ossola: Well, one thing we know he has done is have dinner last night with Anthropic CEO Dario Amodei. He's supposed to meet with several other tech CEOs at the White House tomorrow. What is the purpose or goal of these meetings?
Amrith Ramkumar: So a gathering like this can just serve as a way to let people talk things out. But the industry is very divided on this issue and as a result, so is the administration. And both sides are often pointing the finger at one another. So we'll see whether anything comes out of it. This could be the type of venue where you see the President announce his pick for AI czar. It's still not clear what that person would do or what impact that would have on AI policy. The jury's still out on where this all lands. This AI force concept the President has also talked about, there have been a few details. People were also disappointed last week in the U.S. China talks, that the AI dialogue basically resulted in a high level threat sharing agreement where the U.S. and China will give the other a heads-up if there's a major national security threat caused by AI. So for all the bluster about AI in Washington over the past month, there's really little to show for it.
- talk things out /tɔːk θɪŋz aʊt/ 話し合って問題を解決する、腹を割って話し合う
- point the finger at A /pɔɪnt ðə ˈfɪŋɡər æt/ Aを非難する、Aに責任を押しつける
- the jury's still out /ðə ˈdʒʊriz stɪl aʊt/ まだ結論は出ていない、まだ判断できない
- give A a heads-up /ɡɪv eɪ ə ˈhedz ʌp/ Aに事前に知らせる、注意喚起する
- bluster /ˈblʌstər/ 大げさで威勢のいい発言、強がった発言
- have little to show for A /hæv ˈlɪtl tə ʃoʊ fər/ Aの割には目に見える成果がほとんどない
Alex Ossola: Journal reporter Amrith Ramkumar, thank you so much.
Amrith Ramkumar: Thanks for having me.
Alex Ossola: Meta, which has invested more than a $100 billion in AI, is under pressure to show investors how it plans to make money from that spending. Now it's starting a new AI business aimed at enterprise customers. The division will bring together sales of several AI tools Meta already has, like its Viral Muse productivity agent, a coding tool, access to its top models and agents for businesses. And...
Speaker 5: Three, two, one.
Alex Ossola: SpaceX's Starship entered orbit for the first time today. The launch from a pad in Texas this morning is the 14th test of Starship. It carried 26 satellites that SpaceX added to its current constellation, which delivers internet service to customers around the world. The launch and satellite deployment are key steps as the company wants to move the rocket from a research and development phase to one where it carries payloads that can generate revenue.

In markets, the start of a new week brought more new highs for treasury yields. The yield on benchmark 10-year notes settled at more than 5.24%, a fresh 19-year high, while the 30-year closed at a 24-year high. Stocks slid with the Nasdaq leading the losses in the major indexes. It closed down 0.9%. Boeing was a big decliner today after the Federal Aviation Administration, the FAA, said it would delay certifying Boeing's latest model of its 737 Max plane. The FAA says it's assessing a software glitch, an issue that some industry officials worry is a potential safety risk during landings. The Journal reported over the weekend that Boeing had identified a glitch that could cause an automated navigation feature to fail. Boeing stocks slid almost 7% today.

Three pieces of news from the Trump administration. First, the government rolled back regulations that required cars to be more fuel efficient. The Biden Administration had mandated more than 50 miles a gallon for new vehicles, but the Trump administration today said it would bring that down to an average of 34.5 miles a gallon by model year 2031. Administration officials say the changes will help make cars cheaper by easing expensive engineering requirements for automakers. Critics like environmental groups say those savings are overblown and will be quickly eclipsed by higher fuel costs.
- overblown /ˌoʊvərˈbloʊn/ 実際以上に誇張された、過大評価された
- eclipse /ɪˈklɪps/ ～を覆い隠す、～を凌駕する
Also today, President Trump announced that a company called Mesabi Metallics plans to build a $15 billion steel mill in Iowa. Mesabi, which is based in Minnesota, is part of Indian conglomerate SR Group. The proposed mill, which would be one of the largest in the U.S. is a win for President Trump as he looks to counter voter frustration with the economy ahead of the midterm elections. A White House official said that the plant could begin operating in 2030 and that it would support 1,700 jobs.
And at the FBI, one of Director Kash Patel's top deputies is quitting after roughly a year on the job. Andrew Bailey, a co-deputy director, said in a social media post today that he needed to spend more time with his family. Bailey's departure comes amid a slew of departures and turmoil at the agency and his last day at the Bureau is Friday.
- steel mill /stiːl mɪl/ 製鉄所、製鋼所
mill は「製粉所」だけではなく、原料を加工して製品を作る工場という意味 - a slew of /ə sluː əv/ 大量の、数多くの、相次ぐ
In New York state, prosecutors have reopened an investigation into an alleged 2024 gang rape of a Cornell University student. Earlier this month, her lawyer filed a civil suit against the school saying that the victim was forcibly drugged with ketamine at the Chi Phi fraternity house and gang raped by seven of the fraternity members. The district attorney for Tompkins County, where Cornell is located, said today that his office would present the case against the seven men to a grand jury for potential criminal charges. An attorney for one of the accused men denied the allegations in the civil suit.
- fraternity /frəˈtɜːrnəti/ 男子学生社交クラブ、男子大学生の友愛会
And finally, back in 2023, my colleague Evan Gershkovich was arrested by Russia's security forces. He was the first U.S. journalist to be charged with espionage there since the Cold War. If you're like me, you might wonder, how did he deal with the absolute terror of his arrest, then more than a year in Moscow's infamous Lefortovo prison? By treating it like a reporting trip.
Evan Gershkovich: It felt like this would be the most interesting way to spend my time. I'd already been planning a book before, and then when I got arrested, it made sense that I just simply became a character in that. And so I just started taking notes.
Alex Ossola: He took those notes old school with a pen and paper. As he recently told Wall Street Journal editor-in-chief, Emma Tucker, he wrote in notebooks he treated as diaries.
Evan Gershkovich: So I would copy them each week onto a separate sheet of paper-
Emma Tucker: By hand?
Evan Gershkovich: By hand, and then mail them out to my lawyers so I would have a backup essentially.
Emma Tucker: But everything presumably was being read on the way out?
Evan Gershkovich: Yes. So they have the record of my diaries, but I just figured everything I was saying in the diaries, I didn't have anything to hide, so I was fine with them reading it and having it.
Alex Ossola: Evan's written a book about his experience. It's called This Cursed Beautiful Land, and it's out tomorrow. One of the things he talks about in it is the experience of being arrested during an interview with a source.
Evan Gershkovich: When I went to that interview, it wasn't completely blind to the risks. Still the thought of taking a foreign correspondent prisoner just still felt like a bar that they wouldn't cross. So when I was at the interview and they stormed in, the first feeling was pure fear. And your heart starts beating really quickly.
Alex Ossola: After 16 months in prison and a global campaign for his release, Evan was freed in August 2024. And he says that now, even with the experience behind him, it's changed the way he thinks about journalism.
Evan Gershkovich: The accepted rules and norms are changing of what a foreign correspondent is, what they're allowed to do. More countries are becoming authoritarian. More countries are more willing to no longer treat a foreign correspondent in not a diplomat, but kind of a diplomat where if you're really unhappy with an outlet or a certain journalist, you don't extend their visa, you cancel their accreditation, you kick them out, you don't take them hostage. So I've thought about that a great deal about the risks we take, the situations we put ourselves in.
- espionage /ˈespɪənɑːʒ/ スパイ活動、諜報活動
- be blind to A /bi blaɪnd tə/ Aに気づいていない、Aを認識していない
- authoritarian /əˌθɔːrəˈteriən/ 権威主義的な
- cancel one's accreditation /ˈækrədɪˈteɪʃən/ 記者資格・認定を取り消す
Alex Ossola: You can watch Evan's full interview with Emma Tucker on wsj.com. We'll leave a link in the show notes. And that's What's News for this Monday afternoon. Today's show is produced by Danny Lewis and Anthony Bansie with supervising producer Tali Arbel. I'm Alex Ossola for the Wall Street Journal. We'll be back with a new show tomorrow morning. Thanks for listening.
