Exercise: 1) Show by a qualitative informal reasoning that if we are
Turing emulable then a no-cloning theorem is a necessity. Show more
precisely that IF I am duplicable at some description level THEN if I
observe myself below that substitution level I will discover that I am
made from "object" relying on an infinity (a continuum) of information
states/histories (hardly duplicable "stuff"). Hint: (re)read the UDA.

Exercise 2) (For Stephen :) Show that the 1-person is not 1-duplicable,
show that it is not even 1-nameable. (This can be done also by a
qualitative informal reasoning, but it is also beautifully obtainable
with G and G*, S4Grz, ...)
