Molecular biology?
If computer languages were evolving organisms, may this be a metaphor how genetic/chromosome encoding reshuffles itself, and this approximates some common minimalist packaging of the DNA among all these fifty(++?) programming languages? Can we consider this Quine Relay as a `prequel' ancestral "Hello Dad" gene, and also, how its wonderful aesthetic creativity, familiar layperson recognizable and understandable information and charming symbols at myriad representation levels, is enhancing its survival as a persistent executable(living?) `gene-meme'? Eg, is anyone else posting some of this on Facebook?
