Everyone was obsessed with the new white whale of the AI world this week. We’ll get into it on today’s “Marketplace Tech Bytes: Week in Review.” Plus, Trump floats tariffs on semiconductors from overseas. And a bipartisan Senate bill to ban kids from social media is getting another look. But first, back to that DeepSeek drama. The Chinese AI company took the world and the markets by storm with claims that its class-leading large language model was built at a fraction of the cost of Silicon Valley rivals. DeepSeek claims it spent only $6 million on compute power — at least 16 times less than leading U.S. companies. Marketplace’s Meghan McCarty Carino spoke with Paresh Dave, senior writer at Wired, about all these topics for this week’s Tech Bytes.

President Donald Trump’s return to the White House has been seen by many as a boost for cryptocurrency. During the campaign, he made several crypto-friendly pledges and recently made a splash when he launched his own “meme coin” shortly before the inauguration. The Trump token reached a nearly a $15 billion valuation, though it has since fallen quite a bit. But it continues to provoke questions, like, is it a conflict of interest for a high-ranking official? What the heck is a meme coin anyway?Marketplace’s Meghan McCarty Carino spoke with Axios reporter Brady Dale, author of the Axios Crypto newsletter, to get some answers.

Amid all the executive orders signed by President Donald Trump during his first week in office came a promise to “restore freedom of speech” and end federal censorship. Keen observers may note that freedom of speech is protected by the Constitution. But the order seems to have something more specific in mind. It calls out what it characterizes as the Biden administration’s pressure campaign on social media companies to “moderate, deplatform, or otherwise suppress speech under the guise of combatting misinformation.” Will Oremus, tech news analysis writer at The Washington Post, told Marketplace’s Meghan McCarty Carino that the order is a signal of the president’s continued focus on content moderation online.

There’s no shortage of bullish voices on artificial intelligence among the titans of tech. But even many of the leading evangelists, in addition to prevailing pop culture narratives, tend to strike a note of impending doom when envisioning the future of the technology. Reid Hoffman wants us to consider the alternative. He’s the co-founder of LinkedIn, and a founding investor and former board member of OpenAI before he branched into other ventures, like Inflection AI. And his new book “Superagency: What Could Possibly Go Right with Our AI Future?” explores those alternatives. Marketplace’s Meghan McCarty Carino spoke with Hoffman about what he means by the idea of “superagency.”

Last week’s annual gathering of the rich and powerful at the World Economic Forum in Davos, Switzerland, was a bit overshadowed by the inauguration of Donald Trump in the U.S. The president made a virtual appearance at the conference, delivering a speech that hit on several of his recurring themes: tariffs, inflation and artificial intelligence. AI has been a big topic at the summit for several years. But the way it was treated this year felt different, according to Reed Albergotti, tech editor at news website Semafor. Marketplace’s Meghan McCarty Carino caught up with Albergotti just as he was wrapping up his reporting at Davos.

There’s been quite a firehose of news this week, but we’re going to distill some of it into a nice, tall glass for you on today’s Marketplace “Tech Bytes: Week in Review.” We’ll dig into why some crypto insiders are upset with President Donald Trump over his preinaugural meme coins. Plus, the latest in the TikTok ban rollback and how Congress might respond. But first, amid the flurry of executive orders the president signed during his first week in office, he announced the Stargate project, a private, multiparty venture to build domestic artificial intelligence data centers. In attendance at the White House were OpenAI CEO Sam Altman, Oracle co-founder Larry Ellison and SoftBank CEO Masayoshi Son. The investment could be as much as $500 billion. Marketplace’s Meghan McCarty Carino spoke to Anita Ramaswamy, columnist at The Information, for her take on these stories.

Getting fast, comprehensive and accurate information is crucial during emergencies like the devastating wildfires still raging in the Los Angeles area. And over the last two terrifying weeks, one app has become the place to find it: Watch Duty. Operated by a nonprofit, the app was launched in 2021 to track wildfires in Northern California and now provides coverage for more than 20 states. Marketplace’s Meghan McCarty Carino spoke with David Merritt, Watch Duty’s chief technology officer, about how it all came together.

The explosion of artificial intelligence tools like chatbots has rocked the education world in the last couple years. It’s spurred efforts to prohibit, detect or otherwise build guardrails around these powerful new tools. Some educators, though are embracing them, and Colby College is doing it on an institutional level. Four years ago, before most of the public had ever heard about large language models, this private liberal arts college in Maine established a cross-disciplinary institute for AI to help educators and students integrate the technology into their curricula in an ethical way. We had the college president on back then to discuss, and today we wanted to check back in — this time with Michael Donihue, interim director of the Davis Institute for AI at Colby College.

There’s been a lot of doom and gloom in the tech sector in recent years — the feeling that so many of the advances in internet connectivity, social media and now artificial intelligence might have caused more harm than good, increasing the need for at least caution in the industry and even, possibly, government intervention. But lately a backlash to the backlash has been brewing among techno-optimists. Their movement is called effective accelerationism, a play on the effective altruism community, and its supporters argue that unrestricted technological progress is a force for positive change. It’s received more attention since Donald Trump won the 2024 election. Marketplace’s Meghan McCarty Carino spoke with Nadia Asparouhova, a writer and researcher who’s been following the rise of the effective accelerationist subculture, often shortened to e/acc.

It’s Inauguration Day, and a veritable who’s who of tech are in attendance for the swearing in of Donald Trump as the 47th president of the United States. The massive presence of tech leaders, overtly supporting or just making nice with Trump, represents a stunning reversal from his first term. Today, we’re looking back at what happened in between. President Joe Biden was often seen as taking an adversarial approach to the tech industry.

On this week’s Marketplace “Tech Bytes,” we’ll dive into President Joe Biden’s executive order on artificial intelligence plus a request Meta CEO Mark Zuckerberg made to President-elect Donald Trump. But first, tech news site The Information reported that TikTok plans to completely shut down its app in the U.S. on Sunday and will instead direct users to a website where they can read about the platform’s ban. According to that reporting, TikTok will allow American users to download their data — and, if the ban is overturned down the road, those users will be granted access to it immediately. Marketplace’s Kimberly Adams is joined by Maria Curi, tech policy reporter at Axios, to break down these stories.
