On today’s show: Olympians have taken to social media to celebrate, sometimes to trash talk, but also to discuss their mental health. And Google pulled a controversial Olympics ad featuring its Gemini artificial intelligence tool.

But first, what the stock market sell-off could be saying about the AI boom. Marketplace’s Meghan McCarty Carino discusses all of this with Christina Farr, author of the health tech newsletter “Second Opinion,” who says there’s growing chatter that AI has gotten a bit overinflated.

Who will win the election? What will the vote margin be? Will Donald Trump post on X before November? People can place bets on all these real-world questions — and more — on prediction markets. And these online platforms like PredictIt and Polymarket are increasingly being looked to as crystal balls in this chaotic election, promising real-time political insights and the chance to make a few bucks. Marketplace’s Meghan McCarty Carino spoke to Chris Cohen, the deputy site editor of GQ, who recently wrote about his experience getting in on the action of what appears to be a prediction market “gold rush.”

More than 20 years ago, executives at rival auction houses Sotheby’s and Christie’s were found guilty of coordinating a massive price-fixing scheme. Leaders from the companies held covert meetings, where they set identical commission fees. Today, active antitrust cases show that the ways in which companies might conspire are changing. Algorithms can replace secret meetings, but U.S. regulators say it’s still collusion, whether it’s a human or a bot pulling the strings. Marketplace’s Lily Jamali spoke to Joe Harrington at the University of Pennsylvania’s Wharton School about how antitrust law holds up against new technology.

In the early days of the COVID-19 pandemic, a photo of two little girls in the parking lot of a California Taco Bell went viral. They were doing their schoolwork on laptops in that inconvenient location because the restaurant provided free Wi-Fi, which they didn’t have at home. The girls came to symbolize the digital underclass that’s emerged since the rise of the internet. There are millions of American kids like them, says Nicol Turner Lee, senior fellow at the Brookings Institution. Her analysis of the digital divide is contained in her new book, “Digitally Invisible: How the Internet Is Creating the New Underclass.”

Large language models go through a lot of vetting before they’re released to the public. That includes safety tests, bias checks, ethical reviews and more. But what if, hypothetically, a model could dodge a safety question by lying to developers, hiding its real response to a safety test and instead giving the exact response its human handlers are looking for? A recent study shows that advanced LLMs are developing the capacity for deception, and that could bring that hypothetical situation closer to reality. Marketplace’s Lily Jamali speaks with Thilo Hagendorff, a researcher at the University of Stuttgart and the author of the study, about his findings.

Facebook and Instagram parent company Meta is expanding AI offerings across its products, even as the company gets rid of AI features that haven’t quite landed with consumers. The bottom line? CEO Mark Zuckerberg says “Meta AI is on track to be the most used AI assistant in the world by the end of the year.”Then, the Wall Street Journal’s senior personal tech columnist Joanna Stern shares surprises and regrets on her journey as an electric vehicle owner. But first, this week in Congress, the Senate passed the Children and Teens’ Online Privacy Protection Act, also known as COPPA 2.0, and the Kids Online Safety Act, or KOSA, in a rare bipartisan vote — 91 senators voted in favor, with just three opposing these measures, which aim to reduce harm to kids on the internet.

There’s always been something aspirational about the term “smart home.” It was coined by a residential builder association here in the U.S. back in the mid-’80s, long before the inventions we now think of as hallmarks of the smart home. Today, 42% of American households with internet own at least one smart home device, according to the market research firm Parks Associates. In her new book, “Threshold: How Smart Homes Change Us Inside and Out,” Heather Suzanne Woods of Kansas State University asks whether that’s a good thing.

Extracorporeal membrane oxygenation, or ECMO, can be a lifesaving technology for patients whose organs have failed. It works, essentially, by performing the functions that a healthy person’s lungs and heart would normally do. While using the machine, many recipients of ECMO treatment can walk, talk, even ride a stationary bike, but they can’t leave the hospital with the machine, nor can they survive without it. In a recent article in The New Yorker, emergency physician and writer Clayton Dalton described these patients as “caught on a bridge to nowhere.” Marketplace’s Lily Jamali spoke to Dalton about the complicated ethics of this technology.

Companies competing in the chatbot wars are using something known in the industry as “the Pile” to train their large language models. It’s a trove of open-source data made up of text scraped from all around the internet, including Wikipedia and the European Parliament. Annie Gilbertson, investigative reporter for Proof News, recently took a deep dive into the Pile and discovered something else: a dataset called “YouTube Subtitles.” Marketplace’s Lily Jamali spoke with Gilbertson about her investigation and how YouTube creators feel about their content being used without their consent.

It’s a rare issue that can bring the political parties together in Congress, and the need to regulate social media companies ranks high on that very short list. Two industry veterans want Congress to create an agency that sets safety and privacy rules for platforms — and enforces them. The status quo, they argue, is like letting airlines fly without Federal Aviation Administration oversight. The idea comes from Anika Collier Navaroli and Ellen Pao. Pao, an attorney and now CEO of Project Include, pushed to ban revenge porn on Reddit during her tenure as interim CEO. Navaroli, an attorney and senior fellow at Columbia Graduate School of Journalism, was involved in Twitter’s decision to ban former President Donald Trump from the platform in 2021, when she was a senior policy expert there. Marketplace’s Lily Jamali spoke with Navaroli and Pao about their proposal.
