About half of U.S. states now require some form of online age verification to prevent kids from accessing certain content — usually pornography. But in some cases, that also means broader categories of adult content that include social media. Drew Harwell, tech reporter at The Washington Post, has been following this.

Will Gottsegen, a staff writer at The Atlantic, tests out Meta’s AI smart glasses and gives us a recap of how AI continues to get embedded in consumer tech.

Polystyrene is the chemical compound that makes up styrofoam, which is used for packaging and insulation. But it’s not the most environmentally friendly. By one estimate, 40 million tons of polystyrene were produced globally in 2024, leaving millions of tons of plastic waste. The search for an earth-friendly alternative has led researchers to dig deep and come up with an unlikely solution: fungus. The BBC’s Anna Holligan has this story.

In January, we saw a who's who of tech leaders front and center at President Donald Trump's inauguration. Since, the White House has advocated for the build out of AI infrastructure and put a moratorium on state-level AI regulation. But the Trump administration also added a $100,000 fee to petitions for H-1B visas, which are widely used in the tech sector. To review the year in tech and Trump we called up Suyash Pasi, a research analyst and editor at the nonprofit Human Rights Research Center, who’s been following this shift.

Could AI chat bots replace human doctors? Probably not, but that won’t stop people from trying. Just as they did during the emergence of Google, doctors across the country are grappling with the changing healthcare landscape thanks to artificial intelligence. Today on the show, Dr. Hassan Bencheqroun, a pulmonary and intensive care doctor in San Diego, California, talks about his approach to the intersection of patient care and AI.

Building artificial intelligence tools requires a lot of graphic processing units, and those GPUs need huge amounts of ultra-fast memory to feed them data. Micron Technology is one of a handful of memory chip makers that has been selling a whole lot of memory, thanks to the AI boom. Plus, cloud company Oracle's data center debt is coming under scrutiny. And Merriam-Webster names the word of the year for 2025: slop. Marketplace’s Meghan McCarty Carino spoke with Anita Ramaswamy, columnist at The Information, to learn more on this week’s Marketplace Tech Bytes: Week in Review.

Search engines, social media, e-commerce, and mobile games all make money by selling advertising. But making ads work in AI search might not be so straight forward. Perplexity, for instance, reportedly pulled back on plans to integrate ads into their AI search engine. And internal documents showed the company made only $20,000 in ad revenue in the fourth quarter last year. Marketplace’s Meghan McCarty Carino spoke with Garrett Johnson, professor of marketing at Boston University to get a sense of why jumping into the ad business is difficult.

A career in tech was once seen as a safe bet — the jobs were plentiful, the pay was ample. But this year the tech sector had another “meh” year for hiring according to the job site Indeed. Tech jobs have been declining now for several years, but this year, the losses at least seemed to stabilize, according to Indeed's latest Jobs & Hiring Trends Report. Still, job postings in the industry remain well below their pre-pandemic baseline. Marketplace’s Meghan McCarty Carino spoke with Indeed senior economist Cory Stahle for a look at how this year turned out for the tech job market.

Tech giants are estimated to have spent almost $400 billion in capital expenditures this year, mostly to build data centers for artificial intelligence. A single massive facility can have a price tag in the billions of dollars. And many states want in on that spending spree. Thirty-seven states have some sort of incentive program to attract data centers with the hope of bringing a boost to their local economies. They're giving away hundreds of millions in tax exemptions, according to the National Conference of State Legislatures. Marketplace’s Meghan McCarty Carino spoke with Nicholas Miller, policy associate at NCSL, to learn more.

Gary Marcus, professor emeritus at NYU, explains the differences between large language models and "world models" — and why he thinks the latter are key to achieving artificial general intelligence.

There’s been something of a critical mass of high-profile departures and retirement announcements at Apple in recent weeks. Plus, how will consumers be helped or hurt by a potential merger between Netflix and Warner Bros or a hostile takeover from Paramount? And McDonald's pulls an AI-generated Christmas ad because some folks on social media weren't “lovin' it.” Marketplace’s Meghan McCarty Carino spoke with Joanna Stern, senior personal technology columnist at The Wall Street Journal for this week’s “Tech Bytes: Week in Review.”

The AI boom is propelling a once-obscure group of state regulators into key decision-making roles for the economy. AI needs data centers, data centers need power and power is generally regulated in some way — depending on the state — by public utilities commissions. That's the topic of a new report from the Center on Technology Policy at NYU. Scott Brennen, CTP director and author of the report, said these commissions often make decisions on planning and permitting for new infrastructure and decide the rates utilities charge consumers.

The extended Black Friday sale season means a lot of people have been buying new TVs. The top sets today can display in up to 8K Ultra High Definition, they have deeper blacks, brighter highlights and are thinner and lighter-weight than ever. And yet, modern TVs have their haters — a dedicated group of purists who find them lacking, and would rather hunt down a good old fashioned used plasma.

Prosthetic limbs can be expensive, costing thousands to hundreds of thousands of dollars. So the industry seemed ripe for disruption when 3D printing came along. The technology requires little labor and uses economical materials. But the reality of 3D printing prosthetic limbs isn’t that straightforward, according to writer and University of California, Berkeley, lecturer Britt Young, who uses a prosthetic arm. Marketplace’s Meghan McCarty Carino spoke with Young about why 3D printing has yet to bring down prosthesis costs.

A new report from Stanford and Common Sense Media finds that more than half of U.S. teens use AI chatbots for companionship. But, according to Dr. Darja Djordjevic, an adolescent and adult psychiatrist who co-authored the research, the bots aren't equipped to provide the kind of emotional support young people need when dealing with a mental health issue. Dr. Djordjevic and her team simulated conversations involving various mental health concerns with four of the most popular consumer chatbots and identified several risks; chiefly, their tendency to be sycophantic. A note, this conversation mentions suicide and self-harm.

The Trump administration has been trying for months to ban AI regulations at the state level. And its latest gambit to roll such a measure into the congressional National Defense Authorization Act appears to have failed. House Majority Leader Steve Scalise said Tuesday that GOP leadership is now “looking at other places” to include that measure after reportedly facing pushback from both parties. Plus, New York recently became the first state to enforce an AI law designed to protect consumers from "algorithmic pricing." And Amazon pulled back on AI dubbing for some international content after anime fans complained.

Every day, consumers are confronted with the fragility of our personal data privacy — another data breach, another government agency accessing databases they didn't previously have access to, another consent form popping up to get permission to gather more data. It's almost too much for any one person to keep a handle on, according to Rohan Grover, professor of artificial intelligence and media at American University. He recently co-authored a piece for The Conversation about why data privacy seems to have largely fallen out of the public discourse, even though he says the topic is more urgent than ever.

OpenAI CEO Sam Altman once speculated that we'll soon see the first billion-dollar company run by one person and an army of AI agents. Journalist Evan Ratliff decided to put the idea to the test in the newest season of his podcast, “Shell Game,” where Ratliff and his team of synthetic co-founders, executives and workers launched their startup, HurumoAI. His AI agents designed a logo, built a website and eventually released their own agentic AI service. Marketplace’s Meghan McCarty Carino spoke with Ratliff about what he learned from this whole experience.

Robots are commonplace in factories, and increasingly in warehouses like those run by Amazon. But what about robots to help with household chores — so-called humanoids to load the dishwasher or fold the laundry? To find out, we checked in with Ken Goldberg, professor of engineering at UC Berkeley and co-founder of the AI and robotics company Ambi Robotics. He spoke to Marketplace’s Nova Safo en route from a robotics conference in China.

Marketplace's Matt Levin visits a couple in suburban Sacramento who both use an AI-enabled pendant that acts as a personal assistant — and sometimes, a relationship therapist.
