Beacon in the darkness. 1940's diner. Cultural entities, artefacts and places are simple moments, nodes in time and space. It is true that any particular node in some way encodes the whole culture in its form and the patterned flow of information and energy from, around, through and as that thing. Cultural systems protect themselves…
The ancient emergence of information-encoding mechanisms that seek both optimal self-replication and resilience against catastrophic loss of components and sub-systems - in contemporary manifestation.
A logic of communication is stored in material artefacts and its expression and distributed embodiment in culture evolves over time.
The dynamic activity of the methods, frameworks and algorithms of cultural encryption indicate that the nodes in any sufficiently sophisticated communications or information transmission system are secondary considerations to the primary functioning of a recursive self-replication of those same methods, frameworks and algorithms.
