"Consciousness is not proven to be physical". What else ? If you start speaking about the immortal soul, I am out of this discussion (sorry, pure agnostic atheist here).

Now you speak of the mental state as tied to the physical state as time passes. But as Descartes said, "I think therefore I am", ie all input from the senses (sensory input) cannot be trusted. Why would you trust your eyes, do they really show you the truth ? What about visual illusions ?

What I am saying is that I do not need to be meat, I need to have the *exact* (and that is the point I am willing to discuss: would that ever be possible ?) processes. Is the brain a super-processor ? What's the part of randomness ? Can a neuron and axones be modelized with enough precision to reproduce a thought process ? And finally, is it needed to simulate neurones and axones to reproduce a thought process ? Is there a possibility to use another substrate, other mecanisms and get the same results ? Is it possible to feed it replica inputs, so it thinks it sees with its eyes, ears with its ears (and can touch the ears as touch is just another sense to duplicate/copy over) ?

I do not have the answer to the questions above.

BUT

If I have a *perfect* copy, therefore not discernable, it will be the same. Just as 1=1, the '1' on the left is not the '1' on the right, but they have the exact same properties and behavior in mathematics. You can use either of them.

Ask yourself: what is the difference between an original and a *perfect* copy ? If there is any difference, then the copy is not perfect.
