I listened to Talking to Machines on Radiolab. It was an engaging series of interviews with multiple experts, ranging from computer scientists, to writers, to robotics engineers, to therapists. All surrounding the absolutely fascinating (and sometimes frightening) world of artificial intelligence.
Aside from the incredibly interesting subject matter, the way to interviews were presented and arranged really elevated the program to a whole other level. Character reenactments brought more of a story-like feel to the whole show, rather than it being a methodical, science based research story. And the use of music made certain aspects of the interviews more emotionally gripping. The way they utilized all these different techniques was really brilliant. They made the story far more engrossing than a typical NPR segment.
