It was not that long ago that electric vehicle maker Rivian was drawing comparisons to Tesla. But flagging demand for EVs has not served the company well. Its earnings release this week made that much clear. Also, a look at why American venture capital firms appear to be pulling back from funding startups in China. But first, Amazon has come a long way since it was founded 30 years ago. Its next stop: the Dow Jones Industrial Average. It joins the market indicator Monday. Marketplace’s Lily Jamali is joined by Jewel Burks Solomon, managing director at Collab Capital, for her take on these stories.

AT&T is asking California regulators to be relieved of its obligation to provide basic landline phone service to anyone who wants it. “No customer will be left without voice or 911 service,” AT&T says, but Californians weighing in are, by and large, skeptical. Regina Costa, telecom policy director at the Utility Reform Network, an advocacy group, told Marketplace’s Lily Jamali that having a “carrier of last resort” matters.

Once a week, many of us get that dreaded screen-time report courtesy of our smartphones. But a recent study found keeping track of our average usage doesn’t actually help us control our screen time all that much. Caught in the loop of screen-time shame like so many of us are, New York Times tech reporter Kashmir Hill decided to actually do something about it. Marketplace’s Lily Jamali spoke with Hill about her experience breaking up with her iPhone and replacing it with a flip phone, T9 texting and all, because she’d finally had enough.

As consumers, we’ve all been subjected to the “upsell,” or pressure to pay a little more for a product that’s slightly better. It’s one thing if you’re buying, say, a car or a piece of clothing. The ethical questions get a lot more complicated in health care. Some providers have started integrating artificial intelligence in diagnostic procedures, including screenings for breast cancer. The tools may be available for an additional cost, and questions about their accuracy have been raised. Marketplace’s Lily Jamali spoke with Meredith Broussard, a journalism professor at New York University, about integrating AI into mammograms and her personal experience grappling with the tech.

We often think of music as a mostly auditory experience, but it’s also a physical one, especially for people who are deaf and hard of hearing. Daniel Belquer — a Philadelphia-based technologist, composer and “chief vibrational officer” of Music: Not Impossible — has been studying the relationship between sound and sensation, and how that connection can make music more accessible. “Marketplace Tech” spoke with Belquer about how his vibrating technology is helping people experience music in new ways.

On the show today, Microsoft says groups affiliated with the governments of Russia, China, Iran and North Korea are using AI tools to improve their cyberattacks. Also, Disney is investing $1.5 billion in Epic Games. Can we expect a “Frozen” / Fortnite crossover? We’re not sure yet, but what we can expect is regulatory scrutiny. But first, in Silicon Valley, where software normally gets all the glory, OpenAI’s Sam Altman is reportedly planning a big move into hardware by raising up to $7 trillion for a new AI chips project. Marketplace’s Lily Jamali is joined by Paresh Dave, senior writer at Wired, for his take on this week’s tech news.

On our show last week, we had Sen. Amy Klobuchar share her take on the recent Senate hearing with tech executives. You remember the one, with the execs, including Meta’s Mark Zuckerberg, doing their best to stall in response to searing questions about how to keep kids safe online. Klobuchar told us that hearing may have actually moved the needle on that issue. She stressed to us that such events educate the public and help lawmakers get on-the-record pledges of support for specific bills from tech CEOs. In the absence of federal rules, a patchwork of state laws has filled the void. How’s that going? Nicol Turner Lee, senior fellow at the Brookings Institution, gave Marketplace’s Lily Jamali the rundown.

Cuffing season is that time of year when singles hunker down with someone to keep them warm — temporarily. And Valentine’s Day more or less marks the end of it. So people are about to start flocking back to their dating apps. Adrianus Warmenhoven, cybersecurity expert at NordVPN, told Marketplace’s Lily Jamali that a lot of those apps are eager to vacuum up their personal data.

23andMe has seen its valuation plummet from $6 billion to close to zero, with the Nasdaq threatening to delist the company’s stock. Still, company leaders have high hopes for medical research and a pivot to biotech. Rolfe Winkler has been writing about what happened for The Wall Street Journal, and discussed the company’s financial woes and future roadmap with Marketplace’s Lily Jamali.

On May 24, it will be two years since 19 children and two teachers were killed in the shooting at Robb Elementary School in Uvalde, Texas. Photojournalist Tamir Kalifa has spent much of the last year and a half documenting the lives of the victims’ families and friends in the wake of the tragedy. Last week he was awarded the American Mosaic Journalism Prize for that work. He told Marketplace’s Lily Jamali about how social media is helping the community deal with its grief and bolstering its push for gun control.
