Introducing Brave New Planet, a seven-part series that delves deep into powerful technologies changing our world. They have amazing potential upsides, but we can’t ignore the serious risks. Hosted by Dr. Eric Lander, Brave New Planet is a partnership between the Broad Institute, Pushkin Industries, and the Boston Globe.

In this episode, we're talking about how it's becoming more common to make convincing -- but false -- videos through artificial intelligence. These “deepfakes” can be useful in art, education, and therapy. But they can also be used to harm the reputation of an ex-partner or a stranger. Could they be weaponized to provoke international conflicts or swing elections? When seeing is not believing, who can we trust, and can democracy and truth survive?
