The COVID-19 vaccines from Moderna and Pfizer are in many ways modern miracles. As you know by now, they were developed using technology called messenger RNA, or mRNA, which basically gives the body instructions to create antibodies for the novel coronavirus. It’s the first time a vaccine has been developed in this way. And now that we have this technology, we can start using it on all kinds of viruses, like the flu. Molly speaks with Andrew Hessel, a geneticist and microbiologist. He co-founded Genome Project-write, an international research effort.

This pandemic is the story of lots and lots of deliveries, of groceries, packages and medicine. Companies including Instacart, Amazon and DoorDash use armies of independent contractors that aren’t employees to get those goods out. “Marketplace Tech” producer Stephanie Hughes rode along with a driver for Amazon’s Flex program before the pandemic began to give us a sense of what that work is like.

Tuesday marks one week since the mass shootings in Atlanta that killed eight people, including six Asian women. Police have not labeled the attacks a hate crime. But we know that hate crimes against Asian Americans have been on the rise. Researchers at California State University, San Bernardino, looked at police data from 16 American cities and found that anti-Asian hate crimes more than doubled in 2020. At the same time, online hate speech against Asians has spiked. So as we think about these attacks, what do we know about online hate speech and how it translates to real-world violence? Marielle Segarra talks with Davey Alba, a tech reporter at The New York Times who covers misinformation. She has been following anti-Asian sentiment online during the pandemic.

Joy Buolamwini is a researcher at the MIT Media Lab who pioneered research into bias that’s built into artificial intelligence and facial recognition. And the way she came to this work is almost a little too on the nose. As a graduate student at MIT, she created a mirror that would project aspirational images onto her face, like a lion or tennis star Serena Williams. But the facial-recognition software she installed wouldn’t work on her Black face, until she literally put on a white mask. Buolamwini is featured in a documentary called “Coded Bias,” airing tonight on PBS.

All this week, Congress has been holding antitrust hearings with a specific eye on big tech companies. Also this week, an investigation published in Politico found that nearly a decade ago, commissioners at the Federal Trade Commission apparently ignored evidence that Google was building an anti-competitive monopoly in web search and advertising. Molly speaks with Matt Stoller, research director at the nonprofit American Economic Liberties Project.

At the beginning of the pandemic, almost exactly this time last year, we heard a lot of promises about the types of technology that could help us stop the spread of the disease. One of those tech miracles was thermal cameras — devices that could read someone’s temperature from a distance. Companies bought them in droves, thinking that installing them at the entrances of schools, airports or offices could stop sick people from entering. But do they work, and did they ever? Molly speaks with Conor Healy, the government director at IPVM, a video-surveillance research firm. He recently co-authored a study on fever-scanning devices and said many have one large flaw.

The transition to remote learning exposed a deep digital and device divide, inequality among schools and a lack of preparation for online learning. But some of what we learned, no pun intended, could improve schooling in the future and prepare us for the next disruption. That will take money, political will and stamina. Molly talked with Laura Ruderman, CEO of the nonprofit Technology Alliance, focused on Washington state. This year, the group released a report called “Learning From Calamity.”

We’re looking back on a year of life under the pandemic, and it’s clear that the internet remains everything. As long as you have access. The year showed us just how much that infrastructure could use some improving. We called one of the country’s biggest internet and wireless providers, AT&T, which has been criticized for rolling out high-speed fiber to only about 30% of the homes in its 21-state territory. The company says it’s investing heavily in 5G. It just spent $23 billion on wireless spectrum. The person in charge of building out these networks is AT&T Communications CEO Jeff McElfresh. He told Molly Wood that AT&T plans to keep expanding fiber to 3 million more customers this year and that wireless won’t be the last-mile solution in place of fiber.

It’s been a full year since the coronavirus outbreak became widespread in the U.S. And all this week on our show we’re talking about what we learned or didn’t learn, and what it all means for what comes next. Last year, around this time, we talked with Amy Webb, a futurist and founder of the Future Today Institute, about how businesses might respond to the pandemic and how things might change in the future as a result of such a big direction-changing event. One thing she was really clear on is that most likely the pandemic would accelerate the death of privacy. And now, Amy Webb says, that definitely happened, starting in school.

The White House last week added law professor Tim Wu to the National Economic Council to advise on technology and competition policy. Wu is an ardent antitrust scholar who’s called for breaking up Big Tech companies. And the White House is reportedly also vetting legal scholar Lina Khan for a seat at the Federal Trade Commission. Khan published a paper back in 2017 titled “Amazon’s Antitrust Paradox,” which laid out the ways she saw the tech giant as anti-competitive. Molly speaks with Will Oremus, a senior writer at OneZero. He said Khan and Wu have both essentially argued that, legally speaking, being “too big” is reason enough to be regulated.
