Not really - all you are really saying is that it would be impossible
to distinguish between a genuine concious entity, and one that merely
simulates it to a high level of fidelity, but is nevertheless not
conscious (ie a type of zombie).

Incidently, I'm harping on about genuine randomness and free-will. It
is not immediately obvious to me that free will is essential for
consciousness. My objection does not apply to conscious entities that
nevertheless do not have free will.

However, Bruno will have to convince me that my free will remains
intact before I get into one of his contraptions.

Suppose a Turing Machine augmented with a true random number generator
(quantum, or whatever) produced consciousness while one with only a
pseudo random number generator (a deterministic, algorithmic, but
largely unpredictable generator) did not.

In cryptography we study pseudo RNGs which can be distinguished from
true RNGs only if certain problems can be solved which are thought
to be intractable.  For exmaple, the Blum Blum Shub psuedo RNG can be
distinguished from true randomness only if an extremely large number
can be broken into its prime factors (the same problem underlying the
well known RSA cryptosystem).

It seems implausible that the ability to perform a calculation (factoring
a sufficiently large prime) which is thought to take more computing
power than is available in the universe would make the difference between
consciousness and its absence.
