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.
