Since reading The Upside of Down, I have been interested in simple versus complex systems. That is why this book caught my eye.
Simplexity: Why Simple Things Become Complex (and How Complex Things Can Be Made Simple) is by Jeffrey Kluger. It is not at all like The Upside of Down. It is a collection of stories of different systems that are more or less complex than appear on the surface. Simplexity is written in the pop science format that Malcom Gladwell uses in his books.
For me this book was fun and easy read. It doesn’t cover the growth imperative, collapse or deep collapse concepts that Homer-Dixon explains in The Upside of Down. Maybe it isn’t fair to compare these books, but honestly I only came to this book because I loved The Upside of Down so much.
