People are always advising executives to think about AI like an intern, or PhD-level researcher, or a expert colleague who is occasionally fallible, or even a middle manager. But all these analogies to types of human workers are actually a kind of category error. It doesn't capture how truly bizarre AI models are. We no more understand how these models "perceive" the world than I truly understand how my dog perceives the world. Today's AI is more like working with an alien species than it is working with a human, be that an intern or experienced pro. Recent research from Stanford on the way in which multimodal AI models can experience "mirage reasoning" further highlights this. I cover that research and plenty more in my latest Fortune "Eye on AI" newsletter.

“The fight in America is all about protecting the cultures in places like Miami or Silicon Valley, and keeping us a nation of entrepreneurs,” says Citadel CEO Ken Griffin. There is an optimism in his voice that is rare these days. Griffin is rich, and he’s fearless, that much is not in doubt. And given his incredible wealth and potential influence going forward, it’s worth understanding where Griffin came from and how he developed a set of beliefs about society and the economy. Because if Ken Griffin believes there’s a path to remaking American capitalism—based on what he sees working in Miami—he might be one of the few people on the planet with the money and influence to make it happen.

Americans aren’t getting laid off. And they’re not quitting. They’re simply just not getting hired, and the numbers haven’t been this bad since the pandemic closed the economy by force. The Bureau of Labor Statistics reported Tuesday the hiring rate fell to 3.1% in February, with just 4.8 million hires, the lowest since April 2020. Job openings dropped to 6.9 million, down 358,000 from January. The quits rate held at a low 1.9%, while layoffs also stayed pinned at 1.1%, and retirements fell back near record lows. Everyone, it seems, is staying put, whether in their jobs or in unemployment. “It’s a brutal job market,” Heather Long, chief economist at Navy Federal Credit Union, told Fortune. “To see that 3.1% hiring rate, the lowest since April 2020, when the economy was closed down literally during COVID—it just underscores how little hiring is going on.” Read more: https://lnkd.in/e6v8Ym_g

Another security lapse at Anthropic. This one potentially more serious than last week’s leak of draft blog posts revealing previously a undisclosed model and other documents. This time it is some of the source code for Claude Code, Anthropic’s premier product that has leaked. It could let people reverse engineer Claude Code’s agentic harness or simply duplicate it as open source code. It could also let bad actors potentially bypass guardrails on the use of Claude Code.

"I was always kind of like a precocious young child." In 2025, Olympian Eileen Gu was one of the world’s highest-paid female athletes. Bringing in a reported $23.1 million. After February’s Milan-Cortina Olympics, the 22-year-old athlete, who competes for China, became the most decorated Olympic freeskier in history, with six Olympic medals to her name. Gu was recently honored by the women’s media platform The Shift as a woman shifting culture. In an interview at the Shift’s inaugural gala at Harvard Art Museums, she told Fortune what advice she would give to other women seeking to reach similar professional—and financial—heights in their own fields. 🔗 Read more here: https://lnkd.in/eWtPhbYs

Ken Griffin wants to reshape Miami—and maybe American politics. While many are “shorting” America’s prospects, Griffin is buying, and this certainly isn’t the first time one of his contrarian bets has paid off. He built Citadel not by hiring the typical cast of MBAs but engaging the likes of mathematicians, statisticians, and physicists who boasted great quant skills and learned finance fast. In 2022, fed up with Chicago’s failing schools, crime, and politicians, he moved Citadel’s base to Miami in what was arguably the most stunning corporate relocation in decades. Griffin spoke to Fortune's Shawn Tully about his bullishness on the Sun Belt, which he thinks is the future of American enterprise. Read more: https://lnkd.in/eb-7rVmn

As Americans are barely getting by because of inflation, tariffs, and a cost-of-living crisis, saving for retirement can feel like the priority lowest on the totem pole. But multimillionaire serial investor and entrepreneur Kevin O’Leary says saving is more important than ever before. “What piece of advice do I give my kids over and over and over again about money?” the Shark Tank star questioned in a recent Instagram video. “Don’t spend it. Save it. Invest it. Let it compound. That’s the gift the market gives you. O’Leary’s golden rule of investing is straightforward. | Fortune https://lnkd.in/eSPbwdjx

Gabriel Petersson’s childhood looked a lot like many Gen Z upbringings: collecting Pokemon cards and building worlds in Minecraft, while worries about college and careers sat somewhere in the distant future. But by high school, growing up in a small Swedish town of about 5,000 people, Petersson found himself less interested in just playing games and more curious in how they worked. That quickly snowballed into a deeper obsession with startups, software, and artificial intelligence—what he saw as the next major technological shift. Rather than follow a traditional path of finishing high school, studying computer science, and climbing the corporate tech ladder, Petersson opted out entirely. During his senior year, the then 17-year-old dropped out of high school to cofound Depict.ai, an e-commerce data startup, alongside peers who would later go on to roles at companies like Lovable and Lego.

Federal Reserve Chair Jerome Powell offered a sobering assessment of America’s fiscal health on Monday, telling a Harvard economics class that while the nation’s $39 trillion debt load is not immediately dangerous, the path the country is on demands urgent attention from lawmakers. “The level of the debt is not unsustainable,” Powell said during a wide-ranging conversation before roughly 400 students, “but the path is not sustainable. It will not end well if we don’t do something fairly soon.” The remarks extend a consistent warning Powell has sounded for years, that while the debt level is manageable in the short term, the fiscal trajectory is absolutely not. His comments also came as the average national gas price neared $4 per gallon amid a war in Iran that shows no signs of resolving soon, despite President Trump’s remarks about a potential end to hostilities.
