By this reasoning, then, a book which instructs or compells a person in
how to create a new book just like the first is then "alive".
Or the instruction: "take this message, copy it and paste it 500
times", is then "alive".
To me, a definition of life must include an inherent metabolism
sufficient for the construction of progeny, not just the instructions
telling or compelling another body to do so.
