  • 5. Business Value and Academic Value Durable Knowledge • Less time-limited (with exceptions) • Value comes from adding to the world’s knowledge (the global brain is cumulative/scientific) • Rarely has direct monetary value, but has value in terms of creating the possibility both of future knowledge and of future exploitation and commercial uses
