Social media platforms know a ton about who you are from your online behavior, but there’s one thing they can’t yet know: what you’re thinking at any given moment. That is the last stronghold of privacy in the digital age, except our next guest believes that could be about to fall, too. Nita Farahany is a professor of law and philosophy at Duke University and a leading scholar on the social implications of new technologies. Her new book, The Battle for Your Brain, discusses rapid advances in neurotechnology, the marriage of brain science and AI and what it means for us all. In our conversation, Nita and I cover what exactly science can infer about your thoughts from brain data, about the risk that poses to mental privacy, and how we can avoid with this new technology the kinds of errors we made with social media.
