This seems to me a bit muddled (though in a good way: ideas breaking surface at
the limits of what can be expressed). If the duplicate is a "functional" one then
there can't be any difference to its possible behaviour, by definition.
Colin could have made his point by saying that a PZ is impossible, as only a
conscious person can act like a conscious person when faced with a difficult
enough test, such as doing science. Ironically, this is the same conclusion as
standard computationalism, which Colin opposes.

If PZ's do exist, then there has to be a clear 3-person difference between
the PZ and its PC-possessing brother: different physical structure, if not
different behaviour. A machine based on semiconductors is not conscious,
but the equivalent machine based on thermionic valves and doing the same
computations is. Far-fetched, I don't believe it, and we could never *know*
that it was the case (not even the computers themselves could know it was
the case, i.e. whether they are conscious, unconscious or differently
conscious), but we would have all the information there very clearly 3-person
accessible.
There is another possibility: this machine lacks PC, that identical functionally
*and* physically identical machine has it. The problem is, we need to invoke
magic to explain this.
