I think Library of Babel by Borges is a static manifestation of Turing complete behaviour via the fact that some L-systems are Turing complete. or put another way. Where in the Library of Babel, does the real Hamlet reside? If we consider finding and replacing names with other names, is it still a Hamlet? And if we bring the full force of edit operations and do these in a reversible manner, then where does the actual Hamlet reside? An equivalence class of Hamlet?
