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, director of the Broad Institute of Harvard and MIT. This episode examines deep fakes. It’s getting easy to create convincing—but false —videos through artificial intelligence. These “deepfakes” can have interesting applications in art and education, but they can also cause great harm — from ruining the reputation of an ex-partner to provoking international conflicts or swinging elections. When seeing is not believing, who can we trust, and can democracy and truth survive?  For links to materials referenced in the episode, suggestions for further learning, and guest bios, visit bravenewplanet.org.   Learn more about your ad choices.
