Right now, registrations for websites that use dot-org — like Marketplace — are overseen by a nonprofit organization called the Internet Society. But in November, the Internet Society suddenly announced that it would sell control of those registrations to a one-year-old private equity firm called Ethos Capital for $1.1 billion. That made people worry about the future of nonprofits online due to possible interference with speech or even big price hikes. A group of internet pioneers proposed an all-new nonprofit group to run dot-org. Overseeing all of this is ICANN, the Internet Corporation for Assigned Names and Numbers, which can approve or reject the sale. Andrew McLaughlin, who helped found ICANN, talks to host Molly Wood about it.

This week, Google/Alphabet CEO Sundar Pichai argued that we need to regulate artificial intelligence and also suggested a temporary ban on facial recognition technology. Microsoft President Brad Smith, speaking at the World Economic Forum in Davos, Switzerland, also said we need to create ethical guidelines and rules for how AI should be used. In a new novel out this week by legendary sci-fi author William Gibson, the tech is good enough to decide for itself. The book is called “Agency,” and it’s a sequel to Gibson’s 2014 novel “The Peripheral.” In that book, a super technologically advanced future society can create new alternate histories called stubs for fun or influence the timeline leading to their own present. Gibson talks about “Agency” and the upcoming TV series based on “The Peripheral” with host Molly Wood.

Google recently announced some big privacy changes for its internet browser Chrome. It’s planning to make obsolete what are known as third-party cookies. Cookies are the trackers that advertisers plant so when you shop for shoes one time, you’ll then see ads for them … forever. It’ll also put a limit on the amount of data websites can collect. Other browsers have already made moves to cut tracking and preserve privacy, but what Google does might be significant in that it may change the way the whole web works.

This year’s census is going digital — the first one in history to be available to complete online, instead of on paper. That’s fitting in a world that’s much more connected, compared to 10 years ago, but our online lives mean there’s some risks, too. Disinformation is a big one — mainly fake news designed to influence people’s thinking, which led to intense criticism of social media platforms after the 2016 elections. The Census Bureau is warning that false information could affect the number of people who take part in the upcoming Census.

A lot of tech companies have pledged that their operations are — or will — become carbon neutral. But this week, Microsoft announced plans to become carbon negative in the next 10 years. That means it will invest $1 billion in technologies to remove carbon from the atmosphere in addition to using more renewable energy or offsetting the emissions it creates. In fact, Microsoft announced that by 2050, it wants to remove the equivalent of all the carbon that the company has ever emitted in its 44-years. Ikea is the only other major company that’s made a similar promise, which, let’s be honest, sounds expensive.

When it comes to rolling out 5G, there are a lot of moving parts. At the heart of the 5G story sits Qualcomm, the company that makes wireless chips for your phone and develops and licenses other technology in the wireless industry. Qualcomm has been pushing 5G hard, but there are aspects of the 5G rollout it can’t control. The company is also the subject of a Federal Trade Commission investigation over whether it abused its monopoly position in 4G technology. Host Molly Wood spoke with Cristiano Amon, the president of Qualcomm, about all this at CES in Las Vegas last week.

This year at CES, the big electronics and tech show in Las Vegas held every January, the kickoff keynote presentation for the first time was by an airline CEO, Delta Air Lines’ Ed Bastian. He talked about how tech should help take the stress out of flying and, of course, make you want to pay more to fly Delta. The airline announced a few new features, like updates to its app to include other parts of the trip, like ride-share and hotel. Also, artificial intelligence to improve scheduling, investment in updating airports, including something called “parallel reality” and high-tech displays in airports that can show personalized flight information to lots of different people at the same time.

These days, we’ve all got a Las Vegas buffet of subscription streaming services to pick from. One new one called Quibi — short for quick bites — will launch in April and is only for your phone. Quibi was founded by former Disney executive and producer Jeffrey Katzenberg, and Meg Whitman is CEO. They gave a big presentation about the service last week at CES in Las Vegas. They’ve raised more than $1 billion and signed up a lot of big-name talent to create all new shows and movies. But no video will be longer than 10 minutes at a time.

California’s home solar mandate, which says that newly constructed homes must have panels on the roofs, is now in effect. In a state known for its sunshine, that seems like a sensible idea, but it’s been a contentious path putting this law into place. Builders say that at $8,000 to $10,000 per house, solar energy will drive up prices, potentially making the housing affordability crisis even worse. Advocates say the expense will be offset by lower bills, and then there are the environmental benefits. But some are already looking for loopholes, including an option in the law to build so-called community solar projects, piping in energy from remote solar installations.

Your regular host, Molly Wood, has been in Las Vegas this week — at CES, to be more precise. So we’re going to check in with her and her big takeaways from the show this year. She called into our Marketplace studios from the CES show floor between interviews and panels. First, we started by talking about the big theme this year, 5G — the super-fast mobile broadband tech that’s supposed to revolutionize our online lives — and why we still don’t have it. The following is an edited transcript of our conversation.
