In this short article, we argue that von Neumann's quintessential message with respect to self-replicating automata is genotype + ribotype = phenotype. Self-replication occurs in analogy to nature: The description (genotype) written on the input tape is translated via a ribosome (ribotype) so as to create the offspring universal constructor (phenotype).
