To speak only for myself, I think I have a sufficient understanding of
the thread. Essentially you have shown that one cannot form a set of all
numbers/functions because given any set of numbers/functions it is
always possible, using diagonalization, to generate new
numbers/functions: the Plenitude is too large to be a set. This leads to
a problem with the assumption of the existence of a Universal Dovetailer
whose purpose is to generate all functions. I hope this summary is accurate.
