Friedman discusses how the key to understanding the 21st century is understanding that the planet's three largest forces -- Moore's law (technology), the market (globalization) and Mother Nature (climate change and biodiversity loos) -- are accelerating all at once. And these accelerations are transforming the five key realms: the workplace, politics, geopolitics, ethics, and community. Friedman posits that we should purposely "be late" -- we should pause to appreciate the amazing historical epoch we're passing through and to reflect on its possibilities and dangers.--
