We tend to interpret the mysteries surrounding life in imagery suggested by the most complex system we are aware of at the time. Once nature was described as a body, then a clock in the age of clocks, then a machine in the industrial age. Now in the “digital age” we apply the computational metaphor. To explain the how our minds work, or how evolution advances, we apply the pattern of a very large software program processing bits of information. None of these historical metaphorical pictures are wrong; just incomplete. Ditto for computation.
