Kim Stanley Robinson, writing in an essay, “Remarks on Utopia in the Age of Climate Change,” gave me a nice shout-out on the concept of scaffolding in arena magazine that also was picked up by iai news. Although I talked with Stan about the concept in 2011, it was motivated by a book project with my colleagues Linnda Caporael and Bill Wimsatt, initiated in a KLI workshop in 2010, that came out with MIT Press in 2014: Developing Scaffolds in Evolution, Culture, and Cognition (MIT Press, Amazon).
