The Joe Biden administration is planning to issue an executive order intended to help the country better defend against cyberattacks. One thing the federal government might want to do is just … hire more people to work in cybersecurity. The unemployment rate in the cybersecurity field is close to 0%, according to Erin Weiss Kaya, a strategist focused on cyber-organization with the consulting firm Booz Allen Hamilton. She told “Marketplace Tech” host Molly Wood that the government should be focused less on technical skills or coding and more on people who are used to problem-solving in stressful environments.

What you see on social media isn’t there by accident. It’s there because of an algorithm, the programs that use data to decide what content will keep you online for the longest possible time — so that you’ll see and click more ads. These algorithms are right up there with the secret recipe for Coke, in business terms, but they’re also the secret formula that helps misinformation, conspiracy theories and fake news spread so fast and so far. Congress this week had a hearing to try to understand this dynamic and, maybe, to regulate it. “Marketplace Tech” host Molly Wood speaks with Ina Fried, chief technology correspondent for Axios.

We’ve now been covering potential climate solutions on the show for about two years and yet, we must confess, hadn’t thought much about green hydrogen until President Biden brought it up at the climate summit last week. Biden thinks hydrogen plants could be used in steel and power production and as a zero-emissions alternative fuel. And that it’ll create lots of new jobs. So, how viable is green hydrogen, actually? “Marketplace Tech” host Molly Wood talks with Rachel Fakhry, a policy analyst with the Natural Resources Defense Council. Fakrhy says that in order for this to happen, we’ll have to start producing hydrogen a whole other way.

A recent Senate antitrust hearing focused on smartphone app stores and the fees Apple and Google charge developers: 15% for small developers, 30% for larger ones. Companies that create apps, like Match and Spotify, said the fees were too high for what Apple provides and that the terms can change without warning. Developers also pointed out that sometimes Apple might make apps that compete with external apps, as is the case with Spotify and Tile. “Marketplace Tech” host Molly Wood discusses the whole ecosystem with Julie Ask, a principal analyst covering technology for Forrester Research.

Carbon capture is the talk of the climate scene right now. That’s technology that removes planet-warming carbon dioxide from the air and sequesters it in the Earth. President Joe Biden on Earth Day laid out a vision of net zero emissions by 2050 that relies partly on carbon removal. Also, Elon Musk last week officially launched a $100 million XPrize to fund carbon capture tech. Australia plans to spend more than $400 million on it, too. But climate scientists say carbon capture risks making us think we can just keep emitting all we want. Molly speaks with James Dyke, a senior lecturer in global systems at the University of Exeter, who recently wrote about this in the Conversation. He said there’s another big problem with carbon capture and storage: It doesn’t exist at scale.

The federal government is looking into whether a Florida school district violated privacy law by sharing student data with the county sheriff’s department. An investigation by the Tampa Bay Times found that the Pasco County School District shared grades, disciplinary records and attendance with the Sheriff’s Office, which used the data to create a list of potential future criminals. “Marketplace Tech” host Molly Wood speaks with Amelia Vance, who is with the nonprofit Future of Privacy Forum.

The Federal Trade Commission issued a strongly worded post Monday, warning companies against unfair or deceptive practices in their use of artificial intelligence as well as violations of fair-credit rules. It told companies to hold themselves accountable for their algorithms or “be ready for the FTC to do it for you.” Also, the European Union this week drafted detailed legislation that would regulate AI, including banning some surveillance and social-credit scores. Molly speaks with Ryan Calo, a law professor at the University of Washington, who said the FTC post was a surprise.

As you’ve heard this week, a jury found former Minneapolis police officer Derek Chauvin guilty on all counts in the killing of George Floyd. The key to that case was the video taken by teenager Darnella Frazier with her smartphone. Molly speaks with Allissa Richardson, a professor of journalism at the University of Southern California. She’s the author of the book “Bearing Witness While Black: African Americans, Smartphones and the New Protest #Journalism.” And she argues that smartphones, in most people’s pockets, are a powerful tool for accountability.

The Senate is scheduled to hold a hearing Wednesday on Lina Khan’s appointment to the Federal Trade Commission. Khan is an associate law professor at Columbia University. She published a paper at Yale in 2017 that laid out a new approach to antitrust enforcement, focused on how big tech companies use their power as gatekeepers to harm competitors and consumers. The example she used was Amazon. Molly speaks with Dana Mattioli, a reporter at The Wall Street Journal covering Amazon. In a recent piece, she described some of those behaviors. One example: when the CEO of the PopSockets phone accessories company met with Amazon about counterfeiters.

The shortage of semiconductors that has shut down some car factories isn’t going away anytime soon, even though chipmakers are building new factories and promising to ramp up production. The thing is, computer chips are in everything these days. Look around you right now. If you’re at home, maybe you see your laptop or your internet router. They have chips — that’s obvious. But there could also be a chip in your toaster oven, your light switch or your electric toothbrush. Marielle Segarra speaks with Hal Hodson, a technology correspondent at the Economist. He said the chip shortage is causing delays of all kinds of products, especially the ones you don’t even own yet.
