The document discusses the changing nature of knowledge in the digital age. It notes that knowledge is growing exponentially and is increasingly being generated outside of academia. As a result, the most important skill may be the ability to access just-in-time knowledge as needed rather than retaining large amounts of knowledge long-term. However, others argue that some essential knowledge is still worth retaining. The document also examines debates around assessment and how it can drive shallow learning focused only on passing exams rather than deep understanding.
