NVIDIA gets caught up in the trade war, the titans of Twitter/X debate intellectual property law — and the Federal Trade Commission's antitrust case against Meta kicks off in court.

We're digging into all of it on today's Tech Bytes: Week in Review. Marketplace’s Meghan McCarty Carino speaks with Anita Ramaswamy, columnist at The Information, about what we learned in week one of Meta's monopoly trial.

Flying cars have been a staple of science-fiction visions of the future for ages. Perhaps most famously in “Back to the Future II.” The film may have overshot the mark a bit with Doc and Marty McFly navigating full-on air highways in 2015. But Utah is pushing for the technology to take off by 2034, when the state hosts the Olympic and paralympic winter games.

We're not exactly talking about flying Delorians or vehicles you'd recognize as a car, but rather small, lightweight aircraft for traveling shorter distances. Reporter Caroline Ballard got a first look at the air taxis.

China is responsible for most of the world’s processing of rare earth metals and minerals, but its new export restrictions have raised the stakes for U.S. efforts to build its own supply chain and processing industry. Barbara Arnold, a professor of mining engineering at Penn State, says there are options, but they require time, development and investment.

Surveillance technology like automated license plate readers has become commonplace in policing. They've made it easier to locate stolen vehicles and track suspects, but they've also raised concerns about civil liberties. Cardinal News Executive Editor Jeff Schwaner took a 300-mile drive through the state to see how often his car would be recorded. Marketplace’s Meghan McCarty Carino spoke with Schwaner about his experience and issues related to privacy and who has access to the data.

One area where artificial intelligence has been swiftly adopted is software coding. Google even boasted last year that more than a quarter of its code was generated by AI. But the technology is also generating challenges to the traditional technical job interview, where candidates are given programming problems as a way to assess their skills. And lately it’s become apparent that a lot of applicants are using AI to give themselves a boost, according to recent reporting from Business Insider's Amanda Hoover. Marketplace’s Meghan McCarty Carino spoke with Hoover about the controversy over applicants using AI while interviewing for jobs that often use AI.

The tariff rollercoaster has created a lot of uncertainty in the tech industry. We're digging into how its playing out for makers of consumer tech, e-commerce platforms and AI. Marketplace’s Meghan McCarty Carino speaks with Paresh Dave, senior writer at Wired, about all these topics for this week’s Tech Bytes.

Etsy, the online marketplace known for selling one-of-a-kind handmade items, is hoping that artificial intelligence can boost sales of those crafty creations. The site has been selling less stuff and recently announced a plan to double down on high-quality and unique merchandise over cheap and mass-produced. Now, it's launching AI-curated product collections, based on trends like island luxe or maximalism. They build on the work of human trendspotters, using AI to scan the site and tag thousands of matching products. Nick Daniel, chief product officer at Etsy, explains what the company calls algotorial curation to Marketplace’s Meghan McCarty Carino.

After President Donald Trump's launched his “Liberation Day” tariff agenda, the tech-heavy Nasdaq Composite stock index suffered its biggest plunge since March 2020. The so-called Magnificent 7 — Nvidia, Apple, Meta, Amazon, Google, Microsoft and Tesla — lost a combined $1.8 trillion of market value in two days. The tariff-induced downturn in business conditions is likely to be temporary, according to Daniel Newman, CEO and chief analyst at the Futurum Group, a tech research and advisory firm. Newman told Marketplace’s Meghan McCarty Carino that tech consumers might feel more of the pain, but not much can stop corporate AI adoption and the data center buildout.

Microsoft celebrates its 50th anniversary this month. The company started as a small software startup co-founded by Bill Gates and Paul Allen in an Albuquerque, New Mexico, garage. It went on to revolutionize personal computing, business productivity and now — it hopes — artificial intelligence with its big investment in OpenAI, the maker of ChatGPT. Microsoft has set about integrating the technology across its products, and it recently unveiled a slew of upgrades to its Copilot AI assistant. They include Memory, which retains personal details like the foods you like or your kids' birthdays and can use that information to make your dinner reservations or pick out a gift. The Vision upgrade enables the AI to analyze photos and video and provide tips on, say, redecorating your kitchen. Marketplace's Meghan McCarty Carino spoke with Yusuf Mehdi, Microsoft's consumer chief marketing officer, to learn more about the new features.

Rising demand for electricity, largely to power the artificial intelligence boom, has stirred a resurgence in nuclear energy. Older plants like Three Mile Island in Pennsylvania are being brought out of retirement, but there’s also investment in smaller-scale reactors with different designs. The fresh interest in nuclear generation has also renewed discussion about how to build these facilities ethically, in other words, with an approach that’s sensitive to the needs of the community and the world at large. Marketplace’s Meghan McCarty Carino spoke with Aditi Verma, assistant professor of nuclear engineering at the University of Michigan, who co-created an undergrad course about ethically designing modern nuclear facilities. Verma discussed her effort to train young engineers to transform the industry.

For some engineers, it’s also renewed a discussion about how to build these facilities ethically. Marketplace’s Meghan McCarty Carino spoke with Aditi Verma, professor of nuclear engineering at the University of Michigan who co-created a course for undergraduate students about how to ethically design modern nuclear facilities, about why it’s so important to be teaching this to young, would-be engineers now.

OpenAI — the maker of ChatGPT — keeps raising more money, this time in a $40 billion round led by SoftBank. We’ll get into the strings attached in Marketplace “Tech Bytes — Week in Review.” Plus, what’s going on with Tesla’s sales slump? And how much is its polarizing CEO, Elon Musk, to blame? But first, the clock is ticking on a TikTok sale. The extended deadline, which may or may not be a real deadline according to President Donald Trump, is coming Saturday. As of this episode’s recording, the hugely popular short-form video app was supposed to find a U.S. buyer or be banned, and plenty of suitors have thrown their hats into the ring. Marketplace’s Meghan McCarty Carino spoke with Maria Curi, tech policy reporter at Axios, about all these topics and more.

There’s been mounting concern in recent years about the harms of social media use for kids. The sites can be addictive, ripe for cyberbullying and contribute to increased rates of body dysmorphia, anxiety and depression.

The growing evidence has led at least a dozen states to pass laws attempting to restrict access to online platforms for kids. The Kids Off Social Media Act, a bipartisan bill in the Senate, would bar minors under 13 from social media.

But despite the risks, there can be benefits to finding communities online, especially for LGBTQ+ teens and young adults. A recent report jointly released by the Born This Way Foundation and the nonprofit Hopelab found that young people in these demographics felt significantly safer expressing their identities online compared to in-person spaces.
