This book explores the transformative potential of Artificial Intelligence (AI), specifically large language models like GPT-4, within the realm of education and beyond, with a focus on Khan Academy's tool, Khanmigo. The source is structured around the immediate, interactive capabilities of generative AI—illustrated through engaging storytelling with an AI persona and the ability to pass advanced exams—and then delves into the deeper, technical foundations of these systems, which are essentially powerful, digitally trained "word brains" modeling associations between words. The author champions a concept of "educated bravery," encouraging educators to embrace AI as a tool to solve entrenched educational problems, such as a lack of personalized tutoring and student cheating, by focusing on a Socratic-style tutoring approach that guides students without giving answers. Finally, the text addresses broader societal and ethical concerns, including bias and misinformation, data privacy, and the future of work and assessment in a world where AI will be a collaborator and a necessity for maximizing human potential.
