Apple announced Monday that John Ternus will take over as chief executive on September 1, ending Tim Cook's tenure atop the company he built into the world's most valuable. Cook, 65, will become executive chairman. The transition had been telegraphed — Ternus has been appearing at product unveilings, greeting customers at Apple's London flagship and headlining the company's 50th-birthday celebration with Cook — but the timing underscores how urgent Apple's AI challenge has become. Ternus is a mechanical engineer, 50 years old, who has spent 25 years inside the company working on the iPad, the Mac, AirPods and eventually all of Apple's hardware. Colleagues describe him as a collaborator who keeps meetings focused and loves to race his Porsche at tracks like Laguna Seca. If Jobs was the visionary and Cook the supply-chain master, Ternus is the hardware savant somewhere in between — and he inherits a company that has fallen behind in AI, killed its self-driving car project after billions in development and watched its Vision Pro headset sputter. The case for optimism: Apple still has 2.5 billion active devices in circulation, its App Store AI revenue alone is set to top $1 billion this year, and any AI provider that wants to reach those users will have to pay handsomely.

Kevin Warsh, meanwhile, arrives on Capitol Hill this morning for the confirmation hearing that could put him one step closer to running the Federal Reserve — and his toughest audience may not be the senators but his future colleagues. Warsh's central thesis is that an AI-driven productivity boom will hold down prices and justify the interest-rate cuts Trump wants, an argument he has built around one historical analogy: Alan Greenspan in 1996-97, when the then-chair held rates steady wagering that a productivity boom driven by the internet revolution would keep inflation low. Fed officials have been delicately but unmistakably signaling their skepticism. Several have pointed out that AI is currently boosting demand — data-center construction, electricity prices, surging stock markets — rather than suppressing costs. St. Louis Fed President Alberto Musalem called easing rates on the promise of future productivity gains "risky." Former Chair Janet Yellen said last week she doesn't see the FOMC accepting the argument "in the short run." The 1990s analogy is imperfect in other ways: back then, inflation had already fallen to 2%, budget deficits were shrinking and cheap imports provided a tailwind. Today, inflation has run above 2% for six years, deficits have soared and the Iran war keeps pushing costs up. Even some Warsh supporters now say it isn't the moment to act.

Democrats plan to press Warsh on his finances too. His preconfirmation filing disclosed assets worth more than $100 million but declined to identify the underlying holdings of his largest investments — stakes in a fund run by investor Stanley Druckenmiller — citing confidentiality agreements. Senate Democrats note that the fund has recently appeared to hold shares in Fed-regulated banks, which federal law prohibits a Fed chair from owning. His confirmation remains held up by Sen. Thom Tillis, who says he won't back Warsh until the Justice Department's criminal probe of Powell is resolved. Powell's term as Fed chair ends May 15.

The administration's staffing turbulence continued Monday when Labor Secretary Lori Chavez-DeRemer resigned, becoming the third cabinet member to depart in two months, after Homeland Security Secretary Kristi Noem in March and Attorney General Pam Bondi in April. Chavez-DeRemer met with Trump at her own request and offered to leave, not wanting to be a distraction. She had been under investigation by the Labor Department's inspector general over allegations of misused funds and an improper relationship with a member of her security team, and was scheduled to sit for an interview with the IG on Tuesday — she is no longer expected to appear.

On the war front, a new dimension is coming into view. Iraqi militias backed by Iran launched dozens of explosive drones at Saudi Arabia and other Gulf states during the fighting, in what amounts to a shadow war within the war. According to a Saudi assessment, up to half of nearly 1,000 drone attacks on the kingdom came from inside Iraq, including strikes on a Saudi refinery at the Yanbu oil hub and fields in the Eastern Province. Drones from Iraq also targeted Kuwait's only civilian airport and Bahrain. The Gulf states see Iraq as a theater where they can respond without directly striking Iranian territory. "Iraq is the place where they can all hit back, and it's fair game," said Michael Knights of the advisory firm Horizon Engage. The militias — with roughly a quarter million members, several billion dollars and long-range missiles — played little role in last year's June war with Iran, but this time they are far more aggressive, with some now working directly within Iran's military command structure. Gen. Esmail Qaani, the Revolutionary Guard officer responsible for overseas militias, visited Baghdad over the weekend.

In the slower-burning category of corporate accountability, Tesla owners are mounting a global revolt over Elon Musk's self-driving promises. A class action led by Tom LoSavio, an 80-year-old retired attorney who paid more than $100,000 for a Model S in 2017, alleges Tesla charged customers thousands for a product that didn't and still doesn't exist. The suit won class-action status in September; Tesla is appealing. In the Netherlands, a campaign launched last week is organizing European buyers. A law firm in Australia has assembled its own class action. Wall Street analysts estimate millions of Teslas are on the road with hardware too old to run the most sophisticated version of Full Self-Driving. Musk acknowledged in January 2025 that upgrades would be "painful and difficult," then added: "I'm kind of glad that not that many people bought the FSD package."

The scale of the parallel digital economy keeps growing, too. An investigation into Cambodia's cybercrime industry reveals annual scam-syndicate revenue estimated as high as $19 billion — nearly 40% of the country's GDP, outstripping garment manufacturing. Americans alone lost $10 billion to Southeast Asian online fraud in 2024, a 66% increase from the prior year. Under U.S. and Chinese pressure, Cambodia has raided more than 250 scam centers and deported around 48,000 foreign workers, with over 200,000 more leaving the country. But former workers say operations have simply moved from sprawling compounds into city high-rises, and thousands of apparent scam-job ads have appeared on Telegram since the crackdown began.

And in a vignette of China's robotics ambitions: at Beijing's humanoid-robot half-marathon on Sunday, a machine called Lightning, built by smartphone maker Honor, finished in 50 minutes and 26 seconds — faster than the human world record of 57 minutes and 20 seconds set last month by Uganda's Jacob Kiplimo. Lightning did need human help once, after slamming into a barricade 220 yards from the finish. A title favorite from Unitree collapsed several times and left the course on a stretcher.

A new CEO at the world's most valuable company, a Fed nominee defending an economic theory his future colleagues don't buy, a cabinet that keeps losing members, a shadow war metastasizing through Iraq — Tuesday's landscape is one where the next era keeps arriving before the current one has fully resolved.
