It’s faster than a speeding bullet. It’s smarter than a polymath genius. It’s everywhere but it’s invisible. It’s artificial intelligence. But what actually is it?

Today we ask this simple question and explore why it’s so damn hard to answer.

Special thanks to Stephanie Yin and the New York Institute of Go for teaching us the game. Mark, Daria and Levon Hoover Brauner for helping bring NETtalk to life Grant Sanderson for his unending patience explaining the math of neural nets to us.

A year ago we brought you a show called Shell Game where a journalist named Evan Ratliff made an AI copy of himself. Now on season 2 of the show, Evan’s using AI to do more than just mimic himself — he’s starting a company staffed entirely by AI agents, and making a podcast about the experience. The show is a smart, funny, and truly bizarre look at what AI can do—and what it can’t.

This week we bring you the first episode of Shell Game Season Two, Minimum Viable Company. You can sign up to get the rest of the Shell Game ad-free, and the Shell Game newsletter, at shellgame.co .

Our original host Jad Abumrad returns to share a new podcast series he’s just released. It’s all about Fela Kuti, a Nigerian musician who created a genre, then a movement, then tried to use his hypnotic beats to topple a military dictatorship. Jad tells us about the series and why he made it, and we play the episode that, for us at least, gets to the heart of the matter: How exactly does his music work? What actually happens to the people who hear it and how does it move them to action?

You can find Jad’s entire nine-part series, Fela Kuti: Fear No Man, on Apple or Spotify, or wherever you get your podcasts.

Today on the show, we’re bringing you an episode from Our Common Nature (https://link.podtrac.com/v7mx144d), a new podcast series where cellist Yo-Yo Ma and host Ana González travel around the United States to meet people, make music and better understand how culture binds us to nature. The series features a few familiar voices, including Ana González (host) and Alan Goffinski (producer), from our kids podcast, Terrestrials (https://link.podtrac.com/vysacqn1).

About the episode:
West Virginia is defined by its beauty and its coal, two things that can work against each other. Yo-Yo Ma felt this as soon as stepped foot in its hills.This episode explores how music and poetry help process the emotions of a community besieged with disaster and held together by pride and duty. We travel down the Coal River with third-generation coal miner Chris Saunders, who tells us how coal has saved and threatened his life. Poet Crystal Good shares her poetry, which channels her rage and love. And musician and granddaughter of West Virginia coal miners, Kathy Mattea, explains the beauty of belting out your home state in a chorus. The end of the episode finds host Ana floating down the New River with help from a group of high schoolers and Yo-Yo Ma.

Listen to the full series Our Common Nature (https://link.podtrac.com/v7mx144d).

Featuring music by Yo-Yo Ma, Dom Flemons, and Kathy Mattea and poetry by Crystal Good.

Qasem Waleed is a 28-year-old physicist who has lived in Gaza his whole life. In 2024, he joined a chorus of Palestinians sharing videos and pictures and writing about the chaos and violence they were living through, as Israel’s military bombardment devastated their lives. But Qasem was trying to describe his reality through the lens of the most notoriously confusing and inscrutable field of science ever, quantum mechanics. We talked to him, from a cafe near the Al-Mawasi section of Gaza, to find out why. And over the course of several conversations, he told us how this reality-breaking corner of science has helped him survive. And how such unspeakable violence actually let him understand, in a visceral way, quantum mechanics’ most counter-intuitive ideas.

When we think of China today, we think of a technological superpower. From Huawei and 5G to TikTok and viral social media, China is stride for stride with the United States in the world of computing. However, China’s technological renaissance almost didn’t happen. And for one very basic reason: the Chinese language, with its 70,000 plus characters, couldn’t fit on a keyboard.

Today, we tell the story of Professor Wang Yongmin, a hard-headed computer programmer who solved this puzzle and laid the foundation for the China we know today.

A call to oceanographer Edie Widder about a fish with a very odd immune system quickly becomes something else: a dive into the deep sea, into a world of brilliant light. But down there, the light doesn’t behave like light -- it sparkles and glows, but also drips, squirts, and dribbles. Today, find out how creatures make the light and how they use it, from hunting and hiding to maybe even … talking. And hear about a series of mysterious moments where Edie goes from studying the creatures to becoming one of them.

Love it or hate it, the freedom to say obnoxious and subversive things is the quintessence of what makes America America. But our say-almost-anything approach to free speech is actually relatively recent, and you can trace it back to one guy: a Supreme Court justice named Oliver Wendell Holmes. Even weirder, you can trace it back to one seemingly ordinary eight-month period in Holmes’s life when he seems to have done a logical U-turn on what should be say-able. Why he changed his mind during those eight months is one of the greatest mysteries in the history of the Supreme Court. (Spoiler: the answer involves anarchists, a house of truth, and a cry for help from a dear friend.) Join us in an episode we originally released in 2021, as we investigate why he changed his mind, how that made the country change its mind, and whether it’s now time to change our minds again.

Special thanks to Jenny Lawton, Soren Shade, Kelsey Padgett, Mahyad Tousi and Soroush Vosughi.
