Wednesday on the show, we talked about cryptocurrency’s impact on the environment. Thursday, we talk about its impact on the semiconductor shortage. Miners and gamers are competing for high-powered graphics chips, or GPUs. These are incredibly hard to find right now because of increased pandemic demand. Most are made at the same foundry in Taiwan that’s struggling to produce enough chips for every industry. And yes, crypto miners are snapping them up, too. So to protect their GPU supply, companies like Nvidia are now producing mining-specific chips. “Marketplace Tech” host Molly Wood speaks with Anshel Sag, a semiconductor analyst at the tech advisory firm Moor Insights & Strategy.

Cryptocurrency miners snap up so many computer chips that mining has become a market

Monday through Friday, Marketplace demystifies the digital economy in less than 10 minutes. We look past the hype and ask tough questions about an industry that’s constantly changing.

When you think about gin, what tastes comes to mind? Pine? Maybe citrus or coriander? It can vary quite a bit because unlike some spirits, gin is very lightly regulated. Distillers can throw in all kinds of flavors and call the result “gin” as long it has some minimum requirements. In the U.S., gin is gin as long as the flavor is derived from juniper berries and alcohol by volume is at least 40%. In the European Union, the minimum ABV is 37.5%. But researchers in Edinburgh, Scotland, recently identified the exact elements that define gin using nuclear magnetic resonance spectroscropy. Think of it as something like an MRI scan that lets scientists create a flavor “fingerprint.” The new technique could have big implications for this very old industry. Marketplace’s Lily Jamali spoke with Eve Thomas, who wrote about it for Wired, to learn more.



How science could disrupt the gin industry

When the chemical company DuPont unveiled Teflon in 1946, nonstick pots and pans seemed like a miracle. We now know their coatings contain “forever chemicals,” or PFAS, which don’t break down. These compounds are not only in cookware but in clothing, cosmetics and more — and they contaminate the water millions of us drink. Research shows there’s no safe level of exposure. As the EPA rolls out new limits on PFAS in drinking water, Marketplace’s Lily Jamali asked Tasha Stoiber, senior scientist at the Environmental Working Group, about the tech used to filter it.

Scientists try to prevent “forever chemicals” from being a forever problem


President Joe Biden won Arizona in 2020 by a razor-thin margin, flipping the state blue for the first time in more than 20 years. As a result, Arizona became a hotbed of election misinformation and conspiracy theories, as false claims of a stolen election led to protests outside voting centers, a GOP-backed ballot audit and threats against election workers. Now, with just over 200 days until the 2024 election, experts warn that artificial intelligence could supercharge misinformation and disinformation in this year’s race. So how are election officials in a state that has already been in the trenches preparing for another battle over facts? In this episode of “Marketplace Tech’s” limited series, “Decoding Democracy,” Lily Jamali and Kimberly Adams look back at what happened in Arizona during the last presidential election and how the state became entangled in conspiracy theories. Plus, we hear from Arizona Secretary of State Adrian Fontes about how his office plans to combat AI-charged misinformation this year.

The programming language known as COBOL turns 65 this year. We couldn’t help noticing that’s right around retirement age, but COBOL is nowhere near retirement. It remains a mainstay of IT operations at U.S. government agencies, businesses and financial institutions. Yet the programming language, which is older than the Beatles, is no longer taught at most universities. Glenn Fleishman is a freelance tech journalist who has written about this aging slab of digital infrastructure. Marketplace’s Lily Jamali asked him whether our continuing reliance on COBOL is a problem.

The Labor Department this week confirmed what a lot of Americans have been feeling: Inflation is kind of sticking around, and higher interest rates are likely to as well. We’ll look at what that means for venture capital, which was already slow to flow. Plus, the Joe Biden administration announced a $6.6 billion deal with Taiwan-based semiconductor maker TSMC to build a third production hub in Arizona. We take a look at the ongoing rollout of the CHIPS and Science Act, which makes it all possible. But first, Tesla has settled a lawsuit in the death of a software engineer who was killed driving a Tesla while using the company’s semiautonomous driving software, Autopilot. The suit put scrutiny on Elon Musk’s claims about the software.
 
Marketplace’s Lily Jamali is joined by Jewel Burks Solomon, managing director at Collab Capital, for her take on these stories.
