Lutz Finger, a Cornell University faculty member with a background at LinkedIn, Google, and Snapchat, has developed an online certificate program titled "Designing and Building AI Solutions," which focuses on teaching students to prototype AI-driven products and solutions while acquiring skills in prompt engineering, machine learning, and data handling. To make complex subjects like back propagation and neural networks more accessible and engaging, Lutz introduced an AI-powered teaching assistant named S.A.I., voiced by Kenneth Cukier, a tech writer. This AI co-lecturer turns potentially dry content into interactive and memorable learning experiences, exemplified by playful exchanges between Lutz and S.A.I. The course, featuring over 100 hours of AI content, demonstrates how AI audio can enhance educational outcomes, making content more engaging and accessible for students by showcasing AI principles in action. The innovative use of AI in education not only enriches the learning experience but also expands the reach to a broader audience by enabling content delivery in various languages and voices.
