Dr. John Cohn gave a presentation at the Cairo Makerfaire 2015 about serious play and passion in engineering work. He discussed how computational power has exponentially increased over time due to advances like integrated circuits. However, engineering degree rates in the US peaked in 1970 and declined since. The maker revolution has helped address this by encouraging a playful, experimental approach to engineering. Cohn emphasized being bold and taking risks, as increasing your failure rate can increase your success rate by helping you learn and have more fun.
