The book he mentions is the best book I've read about software architecture that will never be found in the Technical/Computer books section. I've given away at least five copies as Thank You gifts. The beauty of the book is that he presents such a convincing case for the importance of adaptability and a core architecture to enable that - that you start to view the codebase you are working on, heck, even your life through the perspective of: "what decisions am I making now that might impact the ability to change"
Stewart Brand was a pioneer in sharing information even before information was easily shareable (2400 baud modems)
"In late 1968, Brand assisted electrical engineer Douglas Engelbart with The Mother of All Demos, a famous presentation of many revolutionary computer technologies (including the mouse) to the Fall Joint Computer Conference in San Francisco.
Brand surmised that, given the necessary consciousness, information, and tools, human beings might reshape the world they had made (and were making) for themselves into something environmentally and socially sustainable. The fact that he had builders, designers, and engineers as friends surely influenced his reasoning."
