On today’s show, hosts April Glaser and Will Oremus will talk about how Taylor Swift used face recognition to surveil the crowd at a recent concert, and whether that’s smart, scary, or both.

Then they’ll welcome Renée DiResta, an expert on cybersecurity and online misinformation. DiResta is the lead author of a new report to the Senate Intelligence Committee on exactly how Russian operatives weaponized social media in the 2016 election, and why it may be just the beginning of a new era of global information warfare.
