Unchangeable, non-erasable, ever-growing chains of records, are not how nature works. Nature sets limits to growth and energy density, has regular resets on growth, her information is copyable and mutable. Her works have many branches, copies and copy mistakes, use trial and error, and are open to chance and risks, and have to prove their worth by reproductive survival. What ever happened to the genetic algorithm? These fixed block chain ideas will die with digital civilisation.
