Fresh Air: America's first AI-fueled war is unfolding. How'd we get here?
‘Project Maven’ is the story of how the U.S. spent a decade building an AI warfare system that's now being used in the war in Iran. Author and Bloomberg journalist Katrina Manson reveals the people behind that mission, and their belief that AI could make war more precise and save lives. She spoke with Tonya Mosley about the ethics of this technology. A troubling research study found AI models placed in simulated nuclear crisis scenarios chose the nuclear option 95% of the time. Also, Carolina Miranda reviews a Los Angeles art installation that harkens to the old days of cinema.<br/><br/>Also, Carolina Miranda reviews a Los Angeles art installation that harkens to the old days of cinema.<br/><br/>To manage podcast ad preferences, review the links below:<br/><br/>See <a href="https://pcm.adswizz.com">pcm.adswizz.com</a> for information about our collection and use of personal data for sponsorship and to manage your podcast sponsorship preferences.<br/><br/>Learn more about sponsor message choices: <a href="https://podcastchoices.com/adchoices">podcastchoices.com/adchoices</a><br/><br/><a href="https://www.npr.org/about-npr/179878450/privacy-policy">NPR Privacy Policy</a>
Science Friday: Is Punch the monkey really just like us?
<p>When <a href="https://www.sciencefriday.com/segments/why-people-love-punch-the-monkey/?utm_source=wnyc&utm_medium=podcast&utm_campaign=scifri" target="_blank" rel="noopener noreferrer">Punch the monkey</a> was abandoned by his mother, zookeepers gave him a surrogate and unexpected source of comfort: a stuffed animal. Videos of Punch snuggling the stuffie went viral, and, as his stardom rose, millions of us began wondering, “Is Punch OK? Does he have a girlfriend? Is he being bullied by the zoo's other macaques?” Primatologist Christine Webb joins Host Flora Lichtman to talk about the ways humans relate to our closest relatives, and whether we can—and should—map human feelings onto other primates.</p> <p>Guest:</p> <p>Christine Webb is an assistant professor of environmental studies at New York University.
