Can anyone recommend some not-overly-technical books dealing with Von Neumann Universal Constructors and similar minimalist replicating "machines" from a general philosophical or even socio-cultural perspective.
What I find tends to be technically pigeonholed under computing, logic, cellular automata, or biology. I am seeking broader discussions of the processes, problems, and paradoxes entailed by "copying" or "reproducing" in the abstract, and I lack a background in formal logic.
Casting the net wide, I admit. I won't know exactly what I want until I see it.
