Is talking to AI chatbots good for us?

People are using chatbots in all kinds of ways — to search the web, get help with an online purchase, sometimes even for counseling. But there's a lot about this human-AI interaction we don't fully understand. Do these chatbots effectively combat loneliness or worsen social isolation? The answer — so far — is complicated, according to Cathy Fang, a second-year PhD student at MIT Media Lab who, along with researchers from OpenAI, studied how chatbot use affects human social and emotional wellbeing.

Bytes: Week in Review - Meta joins the AI assistant race

Meta launches its own, dedicated AI app that could go head to head with the likes of ChatGPT. Plus, a massive data leak put California Blue Shield members' most sensitive medical details at risk. And how is the health tech investment sector navigating all the recent economic uncertainty from the Trump Administration’s latest trade war? Marketplace’s Meghan McCarty Carino and Christina Farr, managing director at Manatt Health, explore all these topics on this week’s Marketplace Tech Bytes: Week in Review.

When an AI internet search competes against a human internet search

When President Jimmy Carter died late last year, the foundation that runs Wikipedia noticed something unusual: the flood of interest in the late president created a content bottleneck, slowing load times for about an hour. Wikipedia is built to handle spikes in traffic like this, according to the Wikimedia Foundation, but it's also dealing with a surge of bots scraping the site to train AI models, and clogging up its servers in the process, the organization’s chief product and technology officer Selena Deckelmann told Marketplace’s Meghan McCarty Carino.

Meta's news blackout in Canada causes problems during election

Canada's liberal party and its leader Mark Carney are set to remain in control after the country held federal elections Monday. They were the first since Canada adopted the Online News Act in 2023, which requires online content providers — like social media platforms — to negotiate some sort of "fair" payment to news publishers in exchange for using their content. They can also do what Meta did — block news from their Facebook and Instagram platforms altogether. Marketplace’s Meghan McCarty Carino spoke with Marketplace Senior Washington Correspondent Kimberly Adams, who’s been reporting on the election from Canada, to learn more about that law and what happened to the online news environment after it passed.

A battery farm in the Bronx could help clean up New York's power grid

One of the most powerful tools in the fight against climate change is the money sitting in investment portfolios - especially the trillions of dollars invested on behalf of public retirees. That’s money that could continue to fund fossil fuel development, or help pay for climate solutions instead. New York City has implemented an ambitious Net Zero plan for its public pensions. That plan includes divesting from some fossil fuel companies and investing billions of dollars in climate solutions. One company benefiting from that investment is NineDot Energy. Wedged between an elementary school and a big box shopping center in the Northeast Bronx, NineDot Energy is operating a battery farm that the city’s utility company, Con Ed, can call on to help relieve the grid when it gets overstressed. “The batteries hold a combined three megawatts of battery storage. That’s enough to power about 3,000 New York City households for four hours on a hot summer day. Last summer, the battery farm was called half a dozen times, which was enough to reduce greenhouse gas emissions by a combined 24 metric tons. That’s the equivalent of nine thousand car trips on the Cross Bronx Expressway. Currently, the city has the dirtiest energy grid in the state. More than 90% of its power comes from fossil fuels. NineDot Energy is still in growth mode, but battery farms like this could eventually help the grid transition to renewable sources, like wind and solar. “The sun only shines when nature tells it to; the wind only blows when nature tells it to, but people use electricity when they decide to,” explained Adam Cohen, co-founder of NineDot Energy. “A battery helps mediate that process. It pulls in the extra power when it's available, and then puts it back out when people call for it.” On a recent visit to the Bronx facility, 12-year-old Virtue Onoja showed off a mural she helped paint along with other students from the elementary school across the street, envisioning a future powered by cleaner energy. “One thing about me, I'm definitely an artist,” she said. “I drew a clear blue sky, no pollution, no nothing [and] beautiful yellow flowers and the sun.” There are also drawings of windmills and electric school buses. “There's still a lot of pollution, not just in the Bronx, but just in New York in general,” Onoja said. “All of this is the goal that we want to achieve.” This is an excerpt from the latest season of How We Survive.

AI can't read the room

Leyla Isik, a professor of cognitive science at Johns Hopkins University, is also a senior scientist on a new study looking at how good AI is at reading social cues. She and her research team took short videos of people doing things — two people chatting, two babies on a playmat, two people doing a synchronized skate routine — and showed them to human participants. After, they were asked them questions like, are these two communicating with each other? Are they communicating? Is it a positive or negative interaction? Then, they showed the same videos to over 350 open source AI models. (Which is a lot, though it didn't include all the latest and greatest ones out there.) Isik found that the AI models were a lot worse than humans at understanding what was going on. Marketplace’s Stephanie Hughes visited Isik at her lab in Johns Hopkins to discuss the findings.

Bytes: Week in Review - OpenAI's for-profit troubles, FTC sues Uber and how VCs are weathering Trump tariffs

It's the last Friday in April and it's time for Marketplace Tech Bytes Week in Review. This week, we'll talk about how the Federal Trade Commission is suing Uber over its subscription service. Plus, how the VC world is navigating the uncertainty created by the trade war. But first, a nonprofit pivot is facing some challenges. Open AI, the maker of ChatGPT was founded about a decade ago as a nonprofit research lab. It's now looking to restructure as a for-profit — specifically, a public benefit corporation But that transformation is facing resistance. About 10 former Open AI employees, along with several Nobel laureates and other experts, have written an open letter asking regulators in California and Delaware to block the change. They argue that nonprofit control is crucial to Open AI's mission, which is to “ensure that artificial general intelligence benefits all of humanity." Marketplace’s Stephanie Hughes spoke with Jewel Burks Solomon, managing partner at Collab Capital, about how unusual it is to see this kind of conversion.

Is community fact-checking the future of social media moderation?

TikTok is going to be testing a new crowd-sourced fact-checking system called Footnotes. It’s seems similar to the Community Notes systems already in use on other social media, such as X and Facebook. TikTok is also keeping its current fact-checking systems in place. The way these community systems generally work is, say someone makes a post stating "whales are the biggest fish out there." Another user could add a note saying "actually, whales are mammals, and here's a source with more information." Marketplace’s Stephanie Hughes spoke with Vanderbilt psychology professor Lisa Fazio about why this model of "citizen fact-checking" is catching on.
