Early in the pandemic, Sidewalk Labs — an offshoot of Google — announced it was shutting down a big project in Toronto called Quayside. It was meant to be a testing ground for smart-city concepts, a hyperconnected neighborhood from the ground up, with things like an underground network of package-delivery robots. But even before the pandemic, it ran into the same problems that have dogged smart-city projects around the world. Marketplace’s Meghan McCarty Carino speaks with Shannon Mattern, who focuses on this topic in her new book, “A City Is Not a Computer: Other Urban Intelligences.” Mattern said optimizing cities for connectivity often means giving up privacy.

This week, some Microsoft apps, like Outlook, started their slow march to no longer working in Internet Explorer. Next year, the browser itself won’t be supported anymore, as Microsoft moves users to its Edge browser instead. It’s the end of an era for Internet Explorer, which was created back in the ’90s during the browser wars and was the focus of the big antitrust case against Microsoft. Marketplace’s Meghan McCarty Carino speaks with Margaret O’Mara, a professor of history at the University of Washington. O’Mara said the first major browser was Netscape Navigator, co-developed by Marc Andreessen, who saw browsers as the future of everyday computing.

When the Afghan government quickly fell to the Taliban over the weekend, alerts went out with instructions to delete digital activity. Contacts, photos, music — anything that might link someone to something opposed by the Taliban. But in the absence of a coordinated evacuation effort, vulnerable Afghans are now being asked to share personal information online, sometimes to accounts they can’t confirm are legitimate. Marketplace’s Meghan McCarty Carino speaks with Eileen Guo, a senior reporter covering tech policy and ethics at MIT Technology Review. Guo spent two and a half years in Kabul as founder of Impassion Afghanistan the country’s first digital media agency and she says Afghans are being asked to share details about past employment, even scans of their passports.

The Biden administration is reportedly considering recommending a booster shot of the COVID vaccine. But almost a third of Americans over 12 haven’t gotten their first dose yet. Some local health departments are pioneering a new way to reach the hold-outs through micro-influencers. These aren’t the big stars of social media with millions of fans and their own product lines or whatever. Rather, these folks have smaller, local followings in specific communities. The city of San Jose, California and the Knight Foundation recently partnered with about 50 Vietnamese, Latinx and Black micro-influencers to promote vaccines. Marketplace’s Meghan McCarty Carino speaks with Andy Lutzky, the city’s chief communications and marketing officer. He says San Jose’s vaccination rate rose 12 percentage points over the summer, in part because of the influencers’ work.

A lot of disturbing images have come out of Afghanistan. Some taken by professional media, such as people flooding a runway at the airport in Kabul, and many others taken by citizens on their phones and posted to social media. The technological ability of everyday people to document what’s happening on the ground has changed radically from when the conflict began 20 years ago. Marketplace’s Meghan McCarty Carino speaks with Zeynep Tufekci, who studies the social impacts of technology at the University of North Carolina at Chapel Hill. She said that while citizen reporting from Afghanistan is all over the internet, some Afghan journalists and activists are trying to erase all traces of their digital histories.

High-speed internet, safe to say, has become pretty essential to our lives, especially during the pandemic, and yet many Americans struggle to get it. The government has mapped internet access for years, but those maps have overestimated that access. So Congress tasked the Federal Communications Commission with making better ones. The first results came out this month: a map showing mobile coverage from four of the biggest wireless carriers. But better maps for wired broadband are still in the works. Meanwhile, Congress is poised to pass the infrastructure bill, which could allocate $65 billion to improving broadband in the places that need it most. Marketplace’s Meghan McCarty Carino interviews Nicol Turner Lee who researches technology access at the Brookings Institution. Turner Lee says this new mobile data is valuable, since about 15% of Americans — especially young and low-income ones — need it to get online.

The Dixie fire in Northern California has spread more than 700 square miles, making it the largest single fire in California history. There are more than 5,000 firefighters working on the ground to contain it. Increasingly, technology is aiding firefighting efforts like this one — from above. Andre Coleman, a data scientist at Pacific Northwest National Laboratory, helped create a new system that uses data from satellites to map the boundaries of a fire, multiple times a day, and predict what it will do next. He says it’s faster and more precise than traditional fire imaging.

The Intergovernmental Panel on Climate Change, or IPCC, issued a report this week that laid out over nearly 4,000 pages the reality that many are already living: Climate change is here, and much of that change is irreversible — rising temperatures, more and bigger wildfires, extreme droughts and flooding. And to avoid things getting worse, the report says, we’re going to need new technologies that help us capture and remove carbon dioxide in the atmosphere. As part of our series “How We Survive,” we take a look at the role technology can play in a changing climate and how much money is going into it. Marketplace’s Meghan McCarty Carino speaks with Jay Koh, managing director of The Lightsmith Group, which is focused on climate adaptation technology. He says there’s a climate investment boom going on.

Google just announced a slew of new policies to make its products safer for young users. Facebook did the same just last month. Both said they will restrict targeted advertising aimed at kids and teens, though in slightly different ways. They’re also turning more protective features on by default — like setting kids’ Instagram or YouTube accounts to private, turning off autoplay and disabling location history. Google said it will get rid of “overly commercial content” from YouTube Kids. It will also remove images from its search results of users under 18, if they ask. Marketplace’s Meghan McCarty Carino speaks to Ariel Fox Johnson, the senior counsel for global policy at Common Sense Media. She said there’s been growing concern about the ways these technologies could harm children.

Venture capital investors poured more money into startups over the past year than ever before, according to financial data company PitchBook. Venture is, of course, how a lot of tech startups raise money. This finding may come as something of a surprise — investors have historically favored face-to-face meetings before handing a promising founder millions of dollars. The industry is known for being majority white and majority male and, historically, VC firms have placed a lot of value on the intangible qualities of an entrepreneur. But the move to connecting virtually means it’s not just Silicon Valley area companies that are seeing a boost in funding, it’s startups across the U.S.
