I believe that AI can bring about the most significant transformation in education that the world has seen. We can achieve this by providing every student on the planet with an AI-powered personal tutor. This tutor can answer questions, quiz the student, connect different ideas, and provide more than just exercises. It can understand what the student is watching, the context of the video, and answer the age-old question of why the student needs to learn a particular concept. For example, if the student wants to become a professional athlete, the tutor can explain how learning about the size of cells (which is the subject of the video) can be useful for understanding nutrition and how the body works. This AI tutor can help an average student become an exceptional student and a below-average student become an above-average student.
