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.

California relies on a variety of tools to stop and mitigate wildfires, some as low-tech as dumping giant buckets of seawater on the flames. But on the higher-tech side is a new, AI-powered monitoring system called ALERTCalifornia, which was developed at the University of California, San Diego. It’s designed to speedily detect and report wildfires using a network of over 1,000 cameras and sensors. The developers say the network detected over 1,200 blazes across the state during the 2023 fire season, sometimes with impressive quickness. But the system wasn’t quick enough to prevent the current disaster in Los Angeles. Marketplace’s Kimberly Adams spoke with Cyrus Farivar, a senior writer at Forbes, who explored how the fury of the Palisades fire overwhelmed that human-made system.

As fires burn in Los Angeles, many people are going online to find ways to support people who have been temporarily or permanently displaced by the disaster. But like we’ve seen in the aftermath of recent hurricanes and floods, bad actors are spreading misinformation and financial scams. Marketplace’s Kimberly Adams spoke with Steve Grobman, chief technology officer at the cybersecurity firm McAfee, to learn more.

Scam calls about fake warranty renewals, non-existent credit card bills and more are still a global problem. But some companies and telecommunication providers are turning to AI chatbots to intercept the calls before they ever reach a real person. Marketplace’s Meghan McCarty Carino recently spoke with Dali Kaafar, founder and CEO of Apate AI, an Australia-based company creating these chatbots, about how his company is designing these bots to scam the scammers.

Since large language model chatbots hit the scene a few years ago, there’s been a lot of speculation about which jobs they might disrupt most. A lot of bets were on customer service. And recent data show they are becoming more common in the space. A Salesforce survey found a 42% increase in the share of shoppers who turned to AI-powered chatbots for customer service during the 2024 holiday shopping season compared to the previous year. But as AI becomes more powerful and more human-like, will AI voice agents become the norm, even for those more complicated customer cases now handled by human agents? The BBC’s Elizabeth Hotson looked into what a future of synthetic customer service might look like.

CES wraps up in Las Vegas this week. That’s the annual convention where some of the most cutting-edge consumer tech is unveiled. And while we still don’t have a prototype for Rosey, the housecleaning robot from “The Jetsons,” we’ll get into some of the big robot reveals for today’s Marketplace “Tech Bytes: Week in Review.” Plus, YouTubers are taking PayPal to court. A class-action suit alleges that the payments company is messing with their commissions on affiliate links. But first, Meta made big changes to its content moderation policy this week. Facebook’s parent company said it’s cutting ties with third-party fact checkers and switching to a community notes system like the one X uses. Marketplace’s Meghan McCarty Carino spoke with Joanna Stern, senior personal technology columnist at The Wall Street Journal, about her takeaways from the announcement.

This week, Meta CEO Mark Zuckerburg announced some big changes to content moderation strategy. The parent company of Facebook, Instagram, Threads and WhatsApp will no longer be contracting with third-party fact-checkers from the media and nonprofits as it has since 2016. Instead, Meta will follow the lead of X under Elon Musk and rely on crowd-sourced Community Notes to provide additional context on posts. Marketplace’s Meghan McCarty Carino spoke with David Gilbert, a reporter at Wired who covers online disinformation and extremism, to learn more about Meta’s latest pivot.

U.S. ports could be facing another strike as the deadline looms next Wednesday to settle a union contract for 45,000 dockworkers on the East and Gulf coasts. A major sticking point has been automation. Proponents argue that technology can make ports cleaner and more efficient; critics point to lost jobs, high costs and mixed productivity results. While the cost-benefit analysis of port automation is complicated, there are places where the model appears to be succeeding, like Rotterdam in the Netherlands.

By now you probably know the term “large language model.” They’re the systems that underlie artificial intelligence chatbots like ChatGPT. They’re called “large” because typically the more data you feed into them — like all the text on the internet — the better those models perform. But in recent months, there’s been chatter about the prospect that ever bigger models might not deliver transformative performance gains. Enter small language models. MIT Technology Review recently listed the systems as a breakthrough technology to watch in 2025. Marketplace’s Meghan McCarty Carino spoke to MIT Tech Review Executive Editor Niall Firth about why SLMs made the list.
