Russell,
I think you left ou one itzy-bitzy word from your
sentence:
"But the tape can also hold an encoding of the
----[WORKING]----
Turing machine to perform the interpretation."
A Turing machine does nothing (by itself). Don't take
the power for granted. Something has to OPERATE it to
do anything. And not 'any kind' of power. Don't expect
from a cadaver of a wise man to solve Fermat's puzzle.
