The John D. and Catherine T. MacArthur Foundation recently announced the names of 25 people who won an annual fellowship. The highly selective and prestigious award, which has also been described as a “genius grant,” comes with a no-strings-attached stipend of $800,000, which the foundation describes as "an investment in their potential.” The fellowships are given each year to a diverse array of artists, academics, activists and other pioneers in their fields. Yejin Choi is a 2022 MacArthur Fellow and a computer science professor at the University of Washington. She joins us to talk to us about her efforts to make artificial intelligence capable of common sense reasoning, ethical decision-making and recognizing intent behind human language.
