Mark, by @colossusjeremy. This is a story about the head of history's largest nonterritorial empire, who nonetheless remains a prisoner of his rivals. Has he finally found a way out? The profile has been nearly a year in the making. Stern interviewed three dozen people, including Zuckerberg, his MMA coach, and his critics and competitors at the frontier AI labs. He spoke with his parents, Karen and Ed, and watched their son get punched in the face. The story spans Meta HQ in Menlo Park, the Zuckerbergs' homes in Palo Alto and Lake Tahoe, and a party in a Manhattan warehouse with Kylie Jenner and Timothée Chalamet. There is also a sneak peek of Aaron Sorkin's forthcoming sequel about Zuckerberg, sourced via a Hollywood fixer Stern first encountered in Russia. The result is a profile unlike one you've read before.

My conversation with @ericvishria of Benchmark. Eric has spent a decade investing across software and hardware, backing companies like Fireworks, Sierra, Sunday Robotics, and Cerebras. This one is about what history teaches us about the current moment, and a dispatch from inside the AI buildout through his companies. We discuss: - What AWS tells us about how big AI can get - How the goalposts have moved for every software company - Lessons from a decade with Cerebras - China and the energy bottleneck - Benchmark's return to growth investing - Robotics Enjoy!

My seventh conversation with @GavinSBaker. It's about the gap between what the market is doing and what companies are seeing. It's been a tough month or so for public AI names, but there's no sign of a slowdown on the ground in Silicon Valley. We discuss: - Why old GPUs are getting more expensive - Open source vs the frontier - Claude as Wall Street's Walter Cronkite - Whether the buildout gets funded out of cash flow or debt - SpaceX as a data center company - And more Enjoy!

The best pint of Guinness in the world is served at a pub called John Kavanagh’s in Dublin. It is built into the wall of a cemetery. The pub doesn't allow music, singing, or dancing. There’s no TV. There’s no WiFi. If you want to eat, you must go next door to the restaurant. Anthony Bourdain, who visited in 2012, signed the guestbook “heaven looks just like this.”

Guinness used to be an old man's pint, poured in old men's pubs. Now the Irish stout is selling faster than ever. It's the fastest-growing imported beer in the US, and the best-selling beer in British pubs. This resurgence has played out against the backdrop of plummeting alcohol sales worldwide and near-apocalyptic conditions in the hospitality trade. We sent Alex Bilmes, former editor-in-chief of British Esquire, to investigate. He drank at the London pub that sells 20,000 pints of Guinness a week, more than any place on earth. He drank five at the Dublin pub known for the best pint of black stuff in the world. And at 10:30am on a Friday, he drank at St James's Gate, where Guinness has been brewed since 1759. Between pints he consulted TikTok influencers, authors, cemetery workers and Diageo executives, all to understand the revival of a 267-year-old beer that was decidedly uncool just a decade ago. Nothing about Guinness turns out to be black and white. Including the drink, which held up to the light is dark red.

I first followed Sarah because she had a god tier podcast title and her first guest built poker bots. I'm fortunate that she was willing to meet a random anon and have learned a ton from her. This is an awesome profile, with much deserved praise.

In 2018, Sarah Guo became the youngest general partner in Greylock's 60-year history. She was 28. Four years later, she quit to launch Conviction, a firm staked entirely on AI. Before ChatGPT shipped, she seeded Baseten and Harvey; each is now worth over $11 billion. In Conviction's first year, she wrote early checks into Sierra, Cognition, and Mistral; those three companies are now worth, together, $54 billion. Andrej Karpathy worked out of Conviction's office until Anthropic hired him in May. Guo has been close to Jensen Huang for over a decade. Her first two calls after starting the firm were to Sam Altman and Nat Friedman. And yet the investor closest to the AI frontier is betting against its biggest companies. The two big frontier labs, worth close to a trillion dollars apiece, no longer just want to build the models. They also want to build every product and company on top of them, leaving nothing for anyone else. The market is paying as though they might succeed. Of the $300 billion in venture capital deployed in the first quarter of 2026, the biggest quarter in the history of the trade, 65% went to only four companies: Anthropic, OpenAI, xAI, and Waymo. Guo is betting the labs can't build everything, and she spends her days making sure of it. She won Harvey its first client. She flew across the country to take a single Baseten candidate to a four-hour lunch. On one wedding anniversary, she spent the whole weekend on back-to-back calls, keeping two founders on the line so they couldn't speak to rival firms. Twice a year, she flies the world's brightest young founders to San Francisco and inducts them into the fight. In the months @domcooke spent reporting this piece, @saranormous had her fourth child, walked the Met Gala in 45 pounds of chainmail, and still answered her founders' texts within minutes. Guo's parents arrived from China in 1987 with $50, built a company, and took it public at $1.2 billion. Then it went bankrupt. Guo grew up inside that startup. She built its first website, did her homework in a cubicle, and slept over for bug bashes. She loved it. If two labs build everything, no one gets to do that again. Welcome to Sarah's Wager.
