some association... the Japanese studied their temples that withstood hundreds of years and thousands of earthquakes.. and found that there's one common pattern: there are two skeleton structures inside one another, with different loading and strengths, each keeping the other from falling (and they built the Tokyo Skytree this way).
Would be interesting to see if other lasting things in other domains, natural or human-made, physical or virtual, are built this way..
What a great metaphor. If I had known about it, I probably would have used it in the book.
