If you live and breathe tech, you probably already listen to Vox’s Recode Decode (or, at the very least, know its host: Prominent Silicon Valley journalist Kara Swisher). And if you’re not a tech aficionado, you should still be listening to Recode Decode, because of the way it uses themes, issues and developments in tech to unpack big ideas central to our social and political lives, business, media and — occasionally — humanity.

Through one-on-one interviews, Swisher poses tough questions to a host of tech movers and shakers, including Tesla and SpaceX CEO Elon Musk, NSA whistleblower Edward Snowden, and author Tim Ferriss. The discussions don’t merely delve into the technology itself; much of Swisher’s focus is on how the ethics of how we use it. This is where her particular brand of hard-hitting, often intense journalistic acuity comes into its own as she keeps pushing to discover the motivation powering many of tech’s biggest names. It makes for riveting listening.
