I've always liked the books of Stephen Johnson. Interface Culture, written over a decade ago, is still the best book about digital connectivity and culture that I know. Emergence was an early and lucid popular discussion of the idea. Now Johnson has a new book, Where Good Ideas Come From: The Natural History of Innovation, which draws on ecological and network theory, to explore the idea of where ideas come from. Watch the video below and see if you can find the (unspoken) parallel to Brian Arthur's work on the sources of increasing complexity in the drawing! (Hint: look for the reference to the adjacent possible.) Whoa, do I know how to have fun!!!
