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.

On the show today: The ascent of Vice President Kamala Harris to the top of the Democratic Party ticket has stirred the KHive. We’ll look at what the Harris memes mean, in case you just fell out of a coconut tree. Plus, why Waymo is suing alleged vandals of its vehicles in San Francisco. We ask, why now? But first, cookies are here to stay — for a while, anyway. Google is backtracking on its plan, announced in 2020, to do away with the files that advertisers use to track us online. Marketplace’s Lily Jamali spoke with Paresh Dave, senior writer at Wired magazine, about why.

Back in 1990, then-President George H.W. Bush signed the Americans with Disabilities Act, the world’s first comprehensive law for people with disabilities. It was seen as making up for an area in which the Civil Rights Act of 1964 fell short. “The stark fact remains that people with disabilities were still victims of segregation and discrimination, and this was intolerable,” Bush said. Now, the legislation passed at the dawn of the internet age is being adapted to ensure digital access for everyone. That means ensuring access to captions on web videos to support deaf Americans and the ability to resize text so people with low vision can read it. Marketplace’s Lily Jamali spoke with consultant Nicolas Steenhout, who explained how the Department of Justice is updating the rules.

What if receiving a medical diagnosis was as simple as shopping online? The growing home diagnostics industry says it can be. At-home testing was widespread during the COVID-19 pandemic, but more health tech companies also offer DIY kits that test for food allergies, fertility and thyroid function, among other things. Some medical experts are wary of this on-demand model, but health tech investors say it can make health care more accessible. Marketplace’s Lily Jamali spoke to Chrissy Farr, author of the Second Opinion newsletter, and Anarghya Vardhana, a partner at the Maveron venture firm, about the prospects of the industry and how it affects relationships between patients and doctors.

Last Friday felt like something out of a Y2K nightmare after the cybersecurity company CrowdStrike, pushed a software update to all its clients — including health care systems, banks and the federal government — that ended up crashing computer systems worldwide. The fallout is still being felt, particularly in the travel sector, as airliners try to reschedule canceled flights while trying to get everything back to normal. It’s also become something of a reminder that the internet and a lot of the online services we rely on are delicate. Marketplace’s Lily Jamali spoke with Kate Conger, a reporter at The New York Times who recently wrote about this with her colleague David Streitfeld.

Online sales in the U.S. surpassed $14 billion during Amazon Prime Day last week, according to Adobe Analytics. Amazon’s heft and promotional power continue to drive sales, even for rivals, during the shopping jamboree. But in Europe, an important market for the e-commerce giant, lawmakers have become increasingly sensitive to Amazon’s relations with its rivals, as well as its partners and customers. They’ve requested that Amazon hand over information about its product recommendation algorithms, along with data on ads, by Friday. It’s part of compliance with the European Union’s Digital Services Act, a sweeping set of tech regulations that took effect in recent years. Marketplace’s Meghan McCarty Carino discussed it with Theo Wayt, who covers Amazon for The Information.
