Deepfakes—AI-generated fake videos and voices—have become a widespread concern across politics, social media, and more. As they become easier to create, the threat grows. But so do the tools to detect them.

In this episode, Vijay Balasubramaniyan, cofounder and CEO of Pindrop, joins a16z’s Martin Casado to discuss how deepfakes work, how easily they can be made, and what defenses we have. They’ll also explore the role of policy and regulation in this rapidly changing space.
