The Algorithmic Origins Of Life

“To avoid an infinite regress, in which the blueprint of a self-replicating UC contains the blueprint which contains the blueprint . . . ad infinitum, Von Neumann proposed that in the biological case the blueprint must play a dual role: it should contain instructions – an algorithm – to make a certain kind of machine (e.g. UC – Universal Constructor) but should also be blindly copied as a mere physical structure, without reference to the instructions its contains, and thus reference itself only indirectly. This dual hardware/software role mirrors precisely that played by DNA, where genes act both passively as physical structures to be copied, and are actively read-out as a source of algorithmic instructions. To implement this dualistic role, von Neumann appended a “supervisory unit” to his automata whose task is to supervise which of these two roles the blueprint must play at a given time, thereby ensuring that the blueprint is treated both as an algorithm to be read–out and as a structure to be copied, depending on the context. In this manner, the organization of a von Neumann automaton ensures that instructions remain logically differentiated from their physical representation. To be functional over successive generations, a complete self-replicating automaton must therefore consist of three components: a UC, an (instructional) blueprint, and a supervisory unit.”
