In this special episode, Susan Rogers, a record producer turned cognitive neuroscientist, and Daniel Levitin, author of “This Is Your Brain on Music,” get together to discuss what music has meant in their lives, debate what separates a great artist from a generic one, and share some of their favorite tunes. --- Susan’s new book, “This Is What It Sounds Like,” was chosen by our curators — Malcolm Gladwell, Adam Grant, Susan Cain, and Daniel Pink — as one of the eight best works of nonfiction published last year. She recently made a beautiful video e-course about the book, which you can experience by downloading the Next Big Idea app.

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." --- • This episode first aired in June 2021. • To hear Cade summarize his book in only 15 minutes, download the Next Big Idea app. • We launched a new podcast!

The Greek philosopher Epicurus made a rather bold claim over two thousand years ago. The key to life, he said, was simple: pursue pleasure and avoid pain. Around this maxim he developed a school of philosophy, Epicureanism, which promised its adherents that if they took care of their basic needs, surrounded themselves with trustworthy friends, and developed a basic understanding of science, they would be happy. But is it really that simple? Can the advice of someone born 2,363 years ago still hold true? To answer these questions, we turned to Emily Austin, professor of philosophy at Wake Forest University and author of the delightful new book "Living for Pleasure: An Epicurean Guide to Life.” --- • To hear Emily's Book Bite, download the Next Big Idea app • Check out Rufus's conversation with Ryan Holiday • Sign up for our newsletter on LinkedIn

“The future is digital,” they said. Then the pandemic came along and forced that digital future on us. We traded offices for Zooms, gyms for Pelotons, schools for YouTube videos, restaurants for takeout apps. And guess what? It sucked. Many of us longed for face-to-face interactions and real-world experiences, none more so than David Sax, whose new book, “The Future Is Analog,” urges us to stop fantasizing about technological possibilities and start focusing on what we actually need, because it turns out that what a lot of us need is decidedly low-tech. --- • Want to hear David's Book Bite?

Sleep can enhance your creativity, lift your spirits, improve your sense of humor, and amplify your sociability. So why do so many of us struggle to get a good night's rest?

When Bo Seo was 8 years old, his family moved from Korea to Australia. He did not speak a world of English. At school, to deflect attention from his inarticulacy, he became an agreeable wallflower. But that all changed when Bo’s fifth-grade teacher introduced him to competitive debate. Bo was hooked, and in the years to come, he’d not only win two debate world championships but also go on to coach the Australian national team as well as the Debating Union at Harvard, where he earned his undergraduate degree and is currently a law student. Earlier this year, Bo published his first book, “Good Arguments: How Debate Teaches Us to Listen and Be Heard,” which was chosen by our curators as one of the year’s eight best works of non-fiction. In today’s episode, Bo sits down with one of those curators, Adam Grant, to share time-honored techniques for getting your point across, changing minds without hurting feelings, dealing with bullies, and knowing when to shut up. --- Download the Next Big Idea app today by visiting nextbigideaclub.com/app

“Life is a game. There’s no way to understand the human world without first understanding this. Everyone alive is playing a game whose hidden rules are built into us and that silently directs our thoughts, beliefs and actions. This game is inside us. It is us. We can’t help but play.” So begins “The Status Game,” a new book by acclaimed writer Will Storr. He continues: “We play for status, if only subtly, with every social interaction, every contribution we make to work, love or family life and every internet post. We play with how we dress, how we speak and what we believe. … Life is not a journey towards a perfect destination. It’s a game that never ends. And it’s the very worst of us.” Does it have to be? We may not be able to quit the status game, but Will says we can learn to play it better. In this episode, he explains how. --- Download The Next Big Idea app today at nextbigideaclub.com/app/

If the human race lasts as long as a typical mammalian species and our population continues at its current size, then there are 80 trillion people yet to come. Oxford philosophy professor William MacAskill says it's up to us to protect them. In his bold new book, "What We Owe the Future," MacAskill makes a case for longtermism.

For the last 25 years, writer A.J. Jacobs has attempted to live his life as a human guinea pig. “I’ve engaged in a series of experiments on my mind and body,” he says, “some of which have been fruitful, some humiliating failures.

Here’s another episode from our archives that we love: Rufus’s 2020 interview with Ryan Holiday, the author of “Stillness Is the Key,” who shared his tips for slowing down, calming your mind, and accessing the tranquility deep inside.

Today we’re bringing you a timely — and tasty — episode from our archives. Science journalist Amanda Little tells Rufus that the biggest threat posed by climate change is the collapse of our food systems. Provisions we love, like coffee and wine, are losing their flavor. And crops we rely on, like corn and soy, are getting harder to grow. If we don’t change our agricultural practices, we won’t be able to feed the globe’s swelling population. But don’t lose hope. Amanda says that if we can combine the wisdom of traditional farming practices with radical advances in agricultural technology, we might be able to create a healthier, more sustainable, and perhaps even more delicious future.

Today, we are revisiting one of our favorite episodes: an interview with New Yorker staff writer John Colapinto. In his brilliant book, "This Is the Voice," John says that while opposable thumbs are handy, the voice is our species' greatest attribute. We rely on it to communicate and collaborate, woo our mates and protect our children, win wars and make podcasts. John would know. A vocal injury changed his relationship with his instrument and set him on a path to better understand what his voice means to him — and what the voice means to humanity.

What do we lose when we avoid sorrow and chase empty delights, when we mask our pain and feign cheerfulness, when we profess to have no regrets and insist on turning every frown upside down?

Eric Barker is not a people person. “Getting me to write a relationship book,” he says, “is like asking Godzilla to improve the infrastructure in your city.” But he did it anyway.

In January 2020, when the coronavirus started making headlines around the world, Jane McGonigal’s inbox was flooded with emails from Silicon Valley execs, government officials, and non-profit leaders. They all had the same question: “Jane, didn’t you run a simulation of a respiratory pandemic?” Yes, she had. All the way back in 2010. Jane is a game designer. She builds simulations that help players imagine the unimaginable. And in 2010, she invited nearly 20,000 people to immerse themselves in a future world besieged by a global pandemic. “How would you change your habits?” she asked. “What social interactions would you avoid? Can you work from home?” A decade later, when COVID went from nascent threat to full-blown crisis, Jane started hearing from folks who had participated in the simulation. “I’m not freaking out,” one of them said with relief. “I already worked through the panic and anxiety when we imagined it ten years ago.” According to the latest research in psychology and neuroscience, we can all learn to make the shift from panic to poise by training our brains to think about the unthinkable. But what does that training look like? In her new book, “Imaginable” — and on today’s episode — Jane shares evidence-based techniques you can use to see the future coming.

We all strive to think rationally. But it doesn’t always do us much good. Cutting-edge science has revealed that if we want to sharpen our thinking, we need to feel our feelings.

Thousands of years ago, humans crossed a land bridge from Siberia into Alaska. They tried to move south, but a two-mile-high, coast-spanning ice wall stood between them and the rest of the continent. How did they get past it? Scholars have fought over that question for decades. But in her book, “Origin,” Jennifer Raff says breakthroughs in genetics have given scientists an entirely new understanding of how the Americas were peopled and what happened in the millennia that followed.
