What Keeps Facebook Up at Night

On this week’s If Then, Slate’s April Glaser and Will Oremus discuss Elon Musk’s plan to… colonize Mars? They explain how sanctuary cities may unwittingly be sharing data with ICE through police surveillance tech. And Facebook VP Adam Mosseri, head of the news feed, joins the show for a wide-ranging interview. He explains how his team thinks about its responsibility to inform the public, and how they tackle complex problems ranging from fake news in the United States to Facebook-fueled hate campaigns in Myanmar.
