I wasn't aware of this paper before now and am excited to read it. The 15 properties of life were, I believe, his attempt to find the universal rules underlying the design patterns he described in A Pattern Language. I've long thought that most of those properties could be described algorithmically and was curious what sort of system they would converge to. I suppose nature is one easy answer, but it's not a very useful one. For those who are interested, there's a nice summary of the properties and analysis of how they relate to each other at http://web.sfc.keio.ac.jp/~iba/papers/PURPLSOC14_Properties.pdf http://web.sfc.keio.ac.jp/~iba/papers/PURPLSOC14_Properties.... and a more architecturally-focused take at https://www.archdaily.com/626429/unified-architectural-theory-chapter-11 https://www.archdaily.com/626429/unified-architectural-theor....
