People here on HN have compared the evolution of large and old code base to the evolution of DNA before and I think it makes perfect sense: E.g., in both cases, complexity has grown organically over the years/millennia and logic tends to be spread out over dozens of files/genes; change one line of code/gene and suddenly it will impact lots of other things; et cetera.
