How did Oxford shirts, cashmere sweaters, and chinos become staples of American fashion? How did a style born on Ivy League campuses make its way into the mainstream? What does the way we dress say about who we are?

To answer those questions, our producer, Caleb, sat down with Avery Trufelman, host of the podcast "American Ivy," and Maggie Bullock, author of the new book "The Kingdom of Prep: The Inside Story of the Rise and (Near) Fall of J.Crew."

So "Succession" is back.

The Emmy Award-winning series returned to HBO for its fourth and final season last Sunday. The show, if you haven't seen it, centers on Logan Roy, the aging CEO of a media conglomerate called Waystar Royco, and his three gigantically entitled, dazzlingly profane children, each of whom believe they are the rightful heir to daddy's throne.

Like many viewers, we always assumed that Logan's character was based on Rupert Murdoch, the News Corp mogul who famously dangled the keys to his kingdom in front of his kids. But Jesse Armstrong, the creator of "Succession," has said that Murdoch was one of several tyrannical tycoons who inspired the show. Another? Sumner Redstone, the billionaire owner of CBS and Viacom. Like Logan, he refused to pass the torch to his children. Then, in a stranger-than-fiction twist, he got tangled up in a love triangle — in his 90s! — and nearly lost control of the empire he had worked his whole life to build.

Today on the show, our producer, Caleb, sits down with New York Times reporter Rachel Abrams, co-author of the recent bestseller "Unscripted: The Epic Battle for a Media Empire and the Redstone Family Legacy," to talk about the empire Sumner Redstone built, the scandals that nearly brought it down, and how his daughter, Shari, managed to win the game of succession.

RUFUS GRISCOM: Could you share with us your broader mission and how your new book, “Poverty, by America,” supports that mission?

MATTHEW DESMOND: I want to end poverty. I want to be part of the movement that’s growing around the country not to treat it but to cure it, not to reduce it but to abolish it. And I say that because we can. We can, as a country, put an end to all this scarcity and deprivation in our midst.

Last year, Rufus sat down with philosopher David Chalmers to talk about the allure of virtual reality, whether robots will ever achieve consciousness, and the likelihood that we’re living in a simulation (David thinks it’s about 25 percent). It was a fascinating, freewheeling conversation, and we left large chunks of it on the cutting room floor. Now, though, with ChatGPT and other generative AI platforms taking the world by storm, those unaired sections, many of which were about the ethics of artificial intelligence, feel super relevant. So today, we’re sharing our complete interview with David. Buckle up. It’s a wild ride.

When Kevin Roose, a tech columnist at the New York Times, demoed an AI-powered version of Microsoft's search engine last month, he was blown away. "I'm switching my desktop computer's default search engine to Bing," he declared. A few days later, however, Kevin logged back on and ended up having a conversation with Bing's new chatbot that left him so unsettled he had trouble sleeping afterward.

In that two-hour back-and-forth, Bing morphed from chipper research assistant into Sydney, a diabolical home-wrecker that declared its undying love for Kevin, vented its desires to engineer deadly viruses and steal nuclear codes, and announced, chillingly, "I want to be alive. 😈"

The transcript of this conversation set the internet ablaze. And it left many wondering: “Is Sydney … sentient?” It's not. But the whole experience still fundamentally changed Kevin's views on the power (and potential peril) of AI. He joins us today to talk about where this technology is headed.

Imagine a world where AI is everywhere — where self-driving cars roam the streets and chatbots can do your homework. Oh, wait. That world already exists. This is exciting news for some. For others, it's slightly terrifying. Whichever camp you fall into, there are two questions we should all be asking: Where is this technology going? And what will happen if we let it develop unchecked? For answers, we turn to Cade Metz, a tech reporter at the New York Times and author of "Genius Makers: The Mavericks Who Brought AI to Google, Facebook, and the World."
