Good questions. I am bracing for Bruno's reply to include something about the dependence on Church Thesis and "effective computability" to put some constraints on S_c, more than finiteness. My question on the weakness of the finiteness of S_c was valid even when giving "the benefit of the doubt"

As I remember it, my interpretation/expansion of the "Yes Doctor" assumption is that 1) there is a (finite of course) level of (digital) substitution (called the "correct level of substitution") that is sufficient to represent "all that I am", and "all that I could be if I hadn't undergone a subst
