What makes music “real” — is it the instruments, the voice, the creator’s intention or something else entirely? Dustin Ballard, the creative force behind the viral channel “There I Ruined It,” explores the weird, wonderful and sometimes unsettling ways AI is reshaping music.

When the Trump administration dismantled USAID, it was the beginning of a post-aid era, says philanthropist and social entrepreneur Jacqueline Novogratz. Aid may not be coming back but in its place Jacqueline hopes creative solutions will emerge to provide independence and dignity at the community level.

She and Sherrell discuss how Acumen works to build newer and smarter economic models of philanthropy, the responsibilities investors have to helping organizations grow with dignity, and why projects that help local communities excite her.

Today, we’re featuring an episode from NPR’s science podcast Short Wave. In it, host Regina G. Barber talks to computer scientist Ilia Shumailov about maybe the buzziest topic around: AI. I’m sure you know AI models like OpenAI's ChatGPT are trained on millions of examples of human-written text. Nowadays, a lot of content on the Internet is written by these generative AI models. That means that AI models trained now may consume their own synthetic content and suffer the consequences. What's the harm? Find out with this episode of Short Wave.

Artificial intelligence could cost many of us our careers — but that doesn’t mean we should stop its development, says journalist Megan J. McArdle. As she watches AI encroach on her own craft, she shares a fresh take on the 19th-century Luddites, who tried to destroy machines that would upend their trade. Looking back, McArdle reframes today’s fears with a poignant question: If we halt progress to protect the present, what might we be stealing from the future? After the talk, Sherrell highlights how AI might not be replacing human jobs---but creating new ones.

This is the surprising story of how Texas – rich in oil and gas – became America's biggest producer of wind energy. For our first episode, Ryan and Anjali talk with Pat Wood, once George W. Bush’s right hand man and head of Texas's Public Utility Commission, to uncover the innovative approach that turned Texas into a renewable energy powerhouse. It’s a story about what could get done before partisan politics got in the way of good climate policy, and it shows that economic incentives for consumers, government, and companies can play a huge role in supercharging clean energy.

Moore’s Law states that every 1 to 2 years the number of transistors that can fit on a given size computer chip will double. Thanks to this law, chips have gotten smaller, faster, more efficient, and cheaper. But today, there are four key problems that trip up this trend, potentially ending Moore’s Law and fundamentally changing how computing progresses. Sajan Saini and George Zaidan investigate. [Directed by Jeff Le Bars, JetPropulsion, narrated by Adrian Dannatt, music by Stephen LaRosa].
