iHeartPodcasts and Pushkin Industries

Every week on What's Your Problem?, former Planet Money host Jacob Goldstein talks with entrepreneurs and engineers tackling the biggest challenges at the forefront of technology. How do you make a trip to space as routine as a plane flight? How do you turn solar energy into clean fuel? How do you use AI to stop deadly infections before they spread? We hear a lot these days about how the world is getting worse. What's Your Problem? learns from the thinkers and doers trying to make our future better.

iHeartMedia is the exclusive podcast partner of Pushkin Industries.

What's Your Problem?

John Mills is the CEO and co-founder of a nonprofit called Watch Duty. His problem is this: How do you build an app to warn people when they are in immediate danger from a natural disaster? Watch Duty has millions of users and played a key role in the Los Angeles fires of 2025. In the show, John talks about how he built his app with the help of an army of volunteers, and why the government hadn’t already built something like Watch Duty.
 
In this episode, John explains: 
 
 • Why one-quarter of Los Angeles residents downloaded Watch Duty during the 2025 fires
 • Why the all-clear message matters almost as much as the initial warning
 • How they are expanding into flood warnings
 • How to decode firefighter’s radio chatter, and his favorite bit of jargon

Racing Wildfires to Warn the Public

Josh Tyrangiel is the author of “AI for Good: How Real People Are Using Artificial Intelligence to Fix Things That Matter.” On today’s show, Josh talks about some of these real people and the problems they’re working on: a professor trying to understand her nonverbal son, a general who delivered millions of Covid vaccines in 2021, and a hospital CEO trying to reduce the rate of deadly infections. 
 
In this episode, Josh explains: 
 
 • Where AI is helping to reduce hospital infections (and where it’s struggling)
 • Why distributing the Covid vaccine was almost as hard as creating it
 • Why convincing people to use AI is often the hardest problem to solve 
 • Why we should use nuclear weapons as a model for regulating AI

How AI Could Actually Make the World Better

Betsey Stevenson is a labor economist at the University of Michigan, and she was an economic adviser to President Obama. Betsey’s problem is this: How can we create a world where the benefits of AI are broadly shared?
 
Betsey draws on history – including how the invention of household appliances created a crisis of meaning for American women – to understand how we should respond to the challenge of AI. And she suggests policies to help spread the wealth AI could bring.
 
In this episode, Betsey explains: 
 
 • How Engels’ Pause serves as a warning for workers
 • How 20th century women adapted to automation
 • How AI has changed life for college students
 • The argument for taxing AI firms and distributing the proceeds to the public

Finding Meaning (and Money) in the AI Age

In this episode, Brian explains: 
 
 • What he learned building Google Earth 
 • How Pokémon Go players helped build the foundation for robot navigation
 • What it will take to teach AI to understand the physical world.
 • Why GPS is so bad in cities 
 • Why trees are such a big problem for digital mapmakers

Using Pokémon Go to Map the World

Dan Shipper is the co-founder and CEO of Every, a company that publishes newsletters about AI, develops AI-related software, and helps other companies use AI. Dan has two problems.

In this episode, Dan explains: 
 
 • Why managing agents will be a core skill of the future
 • Why AI agents won’t replace you anytime soon 
 • How writers learn faster than AI models 
 • How to give AI the social skills to work in group settings

With her team, Kate has in fact invented a new kind of apple called the Sunflare. It’s arriving in stores in a few years. She also helped to invent the Cosmic Crisp, which is out already.
 
In this episode, Kate explains: 
 
 • Why grocery-store apples have gotten so much better
 • Why some of the most delicious apples never make it into stores 
 • Why it takes decades to invent a new kind of apple
 • How much more we have to learn about apple genetics 
 • How the apple industry is adapting to climate change

Building a Business on the Moon

Aaron Edsinger left his job as director of robotics at Google to start a company called Hello Robot. Aaron’s problem is this: How do you build an affordable robot that people can use to solve real problems at home? The result is a robot that looks nothing like a person. In fact, it’s closer to a Roomba with an arm.
 
In this episode, Aaron explains: 
 
 • Why home robots have barely progressed since the Roomba
 • Why simpler robots can be more useful than complex humanoids 
 • Why the physical world is so much harder for AI than language

Turning Waste Wood Into Buildings

Investors are pouring billions of dollars into nuclear fusion companies. The dream: transform human civilization (and power AI data centers) by providing cheap, abundant energy. But nobody’s figured out how to make it work yet.
 
What will it take to make fusion work at scale – and how will the world be different if it does? To answer this question, Jacob recently hosted a conversation at SXSW between Greg Piefer of SHINE Technologies, Melanie Windridge of Fusion Energy Insights, and Luke Ward of investment firm Baillie Gifford. 
 
In this episode, the guests explain: 
 
 • The incredible promise of fusion
 • What it will take to realize that promise
 • How the AI boom and the demand for power is shaping the fusion industry
 • Why having a ton of money flowing into the field is not necessarily a good thing
