There is so much we need to build right now. The housing crunch has spread across the country; by one estimate, we’re a few million units short. And we also need a huge build-out of renewable energy infrastructure — at a scale some experts compare to the construction of the Interstate highway system.

And yet, we’re not seeing anything close to the level of building that we need — even in the blue states and cities where housing tends to be more expensive and where politicians and voters purport to care about climate change and affordable housing.

Jerusalem Demsas is a staff writer at The Atlantic who obsesses over these questions as much as I do. In this conversation, she takes me through some of her reporting on local disputes that block or hinder projects, and what they say about the issues plaguing development in the country at large. We discuss how well-intentioned policies evolved into a Kafka-esque system of legal and bureaucratic hoops and delays; how clashes over development reveal a generational split in the environmental movement; and what it would take to cut decades of red tape.

Back in 2018, Dario Amodei worked at OpenAI. And looking at one of its first A.I. models, he wondered: What would happen as you fed an artificial intelligence more and more data?

He and his colleagues decided to study it, and they found that the A.I. didn’t just get better with more data; it got better exponentially. The curve of the A.I.’s capabilities rose slowly at first and then shot up like a hockey stick.

Amodei is now the chief executive of his own A.I. company, Anthropic, which recently released Claude 3 — considered by many to be the strongest A.I. model available. And he still believes A.I. is on an exponential growth curve, following principles known as scaling laws. And he thinks we’re on the steep part of the climb right now.

When I’ve talked to people who are building A.I., scenarios that feel like far-off science fiction end up on the horizon of about the next two years. So I asked Amodei on the show to share what he sees in the near future. What breakthroughs are around the corner? What worries him the most? And how are societies that struggle to adapt to change and governments that are slow to react to them supposed to prepare for the pace of change he predicts? What does that line on his graph mean for the rest of us?

The internet is in decay. Do a Google search, and there are so many websites now filled with slapdash content contorted just to rank highly in the algorithm. Facebook, YouTube, X and TikTok all used to feel more fun and surprising. And all these once-great media companies have been folding or shedding staff members, unable to find a business model that works.

And into this weakened internet came the flood of A.I.-generated junk. There’s been a surge of spammy news sites filled with A.I.-generated articles. TikTok videos of A.I.-generated voices reading text pulled from Reddit can be churned out in seconds. And self-published A.I.-authored books are polluting Amazon listings.

According to my guest today, Nilay Patel, this isn’t just a blip, as the big platforms figure out how to manage this. He believes that A.I. content will break the internet as we know it.

“When you increase the supply of stuff onto those platforms to infinity, that system breaks down completely,” Patel told me “Recommendation algorithms break down completely. Our ability to discern what is real and what is false breaks down completely. And I think, importantly, the business models of the internet break down completely.”

Patel is one of the sharpest observers of the internet, and the ways technology has shaped and reshaped it. He’s a co-founder and the editor in chief of The Verge, and the host of the “Decoder” podcast. In this conversation, we talk about why platforms seem so unprepared for the storm of A.I. content; whether an internet filled with cursory A.I. content is better or worse than an internet filled with good A.I. content; and if A.I. might be a kind of cleansing fire for the internet that enables something new and better to emerge.

This episode of “The Ezra Klein Show” was produced by Claire Gordon. Fact-checking by Michelle Harris, with Kate Sinclair and Mary Marge Locker. Our senior engineer is Jeff Geld, with additional mixing from Isaac Jones and Efim Shapiro. Our senior editor is Claire Gordon.

There’s something of a paradox that has defined my experience with artificial intelligence in this particular moment. It’s clear we’re witnessing the advent of a wildly powerful technology, one that could transform the economy and the way we think about art and creativity and the value of human work itself. At the same time, I can’t for the life of me figure out how to use it in my own day-to-day job.

So I wanted to understand what I’m missing and get some tips for how I could incorporate A.I. better into my life right now. And Ethan Mollick is the perfect guide: He’s a professor at the Wharton School at the University of Pennsylvania who’s spent countless hours experimenting with different chatbots, noting his insights in his newsletter One Useful Thing and in a new book, “Co-Intelligence: Living and Working With A.I.”

This conversation covers the basics, including which chatbot to choose and techniques for how to get the most useful results. But the conversation goes far beyond that, too — to some of the strange, delightful and slightly unnerving ways that A.I. responds to us, and how you’ll get more out of any chatbot if you think of it as a relationship rather than a tool.

Mollick says it’s helpful to understand this moment as one of co-creation, in which we all should be trying to make sense of what this technology is going to mean for us. Because it’s not as if you can call up the big A.I. companies and get the answers. “When I talk to OpenAI or Anthropic, they don’t have a hidden instruction manual,” he told me. “There is no list of how you should use this as a writer or as a marketer or as an educator. They don’t even know what the capabilities of these systems are.”

Donald Trump can seem like a political anomaly. You sometimes hear people describe his connection with his base in quasi-mystical terms. But really, Trump is an example of an archetype — the right-wing populist showman — that recurs across time and place. There’s Jair Bolsonaro in Brazil, Boris Johnson in Britain, Javier Milei in Argentina. And there’s a long lineage of this type in the United States too.

So why is there this consistent demand for this kind of political figure? And why does this set of qualities — ethnonationalist politics and an entertaining style — repeatedly appear at all?

John Ganz is the writer of the newsletter Unpopular Front and the author of the forthcoming book “When the Clock Broke: Con Men, Conspiracists, and How America Cracked Up in the Early 1990s.” In this conversation, we discuss how figures like David Duke and Pat Buchanan were able to galvanize the fringes of the Republican Party; Trump’s specific brand of TV-ready charisma; and what liberals tend to overlook about the appeal of this populist political aesthetic.

We’ll be back on Friday with a new episode. In the meantime, we wanted to share one of our favorite recent episodes from our sister podcast, “Matter of Opinion.”

Why does the economy look so good to economists but feel so bad to voters?

The Nobel laureate economist Paul Krugman joins the hosts on “Matter of Opinion” to discuss why inflation, interest rates and wages aren’t in line with voters’ perception of the economy. Then, they debate with Paul how big of an influence the economy will be on the 2024 presidential election, and which of the two presumed candidates, Joe Biden and Donald Trump, it could benefit. Plus, Ross Douthat’s lessons on aging, through Michael Caine impressions.

“The Trip” scene: “This Is How Michael Caine Speaks”

American policy is uniquely hostile to families. Other wealthy countries guarantee paid parental leave and sick days and heavily subsidize early childhood care — to the tune of about $14,000 per year per child, on average. (The United States, by contrast, spends around care-biden.html">$500 per child per year.) So it’s no wonder our birthrate has been in decline, with many people saying they’re having fewer children than they would like.

Yet if you look closer at those other wealthy countries, that story doesn’t entirely hold. Sweden, for example, has some of the most generous work-family policies in the world, and according to the most recent numbers from Our World in Data, from 2021, their fertility rate is 1.67 children per woman — virtually identical to ours.

Caitlyn Collins is a sociology professor at Washington University in St. Louis and the author of “Making Motherhood Work: How Women Manage Careers and Caregiving.” To understand how family policies affect the experience of child-rearing, she interviewed over a hundred middle-class mothers across four countries with different parenting cultures and levels of social support for families: the United States, Sweden, Italy and Germany. And what she finds is that policies can greatly relieve parents’ stress, but cultural norms like “intensive parenting” remain consistent.

In this conversation, we discuss how work-family policies in Sweden frame spending time with children as a right rather than a privilege, how these policies have transformed the gender norms around parenting, why family-friendly policies across the globe don’t increase birthrates, how cultural pressures in America to be both an ideal worker and an ideal parent often clash, why many American parents feel it’s impossible to have more than one or two children, how cultural discourse has led younger women to “dread” motherhood and more.

For a long time, the story about the world’s population was that it was growing too quickly. There were going to be too many humans, not enough resources, and that spelled disaster. But now the script has flipped. Fertility rates have declined dramatically, from about five children per woman 60 years ago to just over two today. About two-thirds of us now live in a country or area where fertility rates are below replacement level. And that has set off a new round of alarm, especially in certain quarters on the right and in Silicon Valley, that we’re headed toward demographic catastrophe.

But when I look at these numbers, I just find it strange. Why, as societies get richer, do their fertility rates plummet?

Money makes life easier. We can give our kids better lives than our ancestors could have imagined. We don’t expect to bear the grief of burying a child. For a long time, a big, boisterous family has been associated with a joyful, fulfilled life. So why are most of us now choosing to have small ones?

I invited Jennifer D. Sciubba on the show to help me puzzle this out. She’s a demographer, a political scientist and the author of “8 Billion and Counting: How Sex, Death and Migration Shape Our World.” She walks me through the population trends we’re seeing around the world, the different forces that seem to be driving them and why government policy, despite all kinds of efforts, seems incapable of getting people to have more kids.Mentioned:

President Biden gave a raucous State of the Union speech last Thursday, offering his pitch for why he should be president for a second term. It’s the clearest picture we have yet of Biden’s campaign message for 2024. But while he listed off all kinds of proposals, it’s not as easy to parse what a second Biden term might actually look like. So I sat down with my editor Aaron Retica, who had a lot of questions for me about the speech itself and what Biden would be likely to accomplish if he got another four years in the job.

We discuss how klein-biden-audio-essay.html">my argument for Biden to step aside holds up after he gave such a deft, high-energy performance; what a second Biden administration would likely do when it comes to abortion rights and foreign policy; the issues that didn’t receive much attention in the speech but would likely play a huge role in a second Biden term; the strongest 2024 campaign message that I’ve heard so far; and whether this is a Locke election or a Hobbes election — and what that means.

When the Supreme Court overturned Roe v. Wade, it scrambled the landscape of abortion access in America, including in ways that one might not entirely expect. Many conservative states made the procedure essentially illegal — that part was predictable. But there’s also been this striking backlash in blue states, with many of them making historic efforts to expand abortion access, for both their residents and for women living in abortion-restricted states.

And this has created all kinds of new battle lines — between states, and states and the federal government — involving travel, speech, privacy and executive power. It’s an explosion of conflicts and constitutional questions that the legal historian Mary Ziegler says has no parallel in modern times. She’s the author of six books on reproductive rights in America, including “Roe: The History of a National Obsession,” and the Martin Luther King Jr. professor of law at the University of California, Davis. “We’re seeing, from conservative and progressive states, moves to project power outside of their borders in ways we really haven’t seen in a really long time,” she told me.

In this conversation, Ziegler explains the bifurcated abortion landscape that has emerged since the decision in Dobbs v. Jackson Women’s Health Organization overturned Roe. We discuss the different political and legal strategies conservative and progressive states are using to pursue their opposing goals; why the abortion rate has gone up, even as 14 states have implemented near-total bans on abortion; and how a second Trump administration could try to restrict access to abortion for all Americans, no matter what states they live in.
