Earlier quoted context omitted.
You're just assuming that mimicry of a thing is not equivalent to the thing itself. This isn't true of physical systems (simulated water doesn't get you wet!) but it is true of information systems (simulated intelligence is intelligence!).
But a simulated mind is not a mind. This was already debated years ago with the aid of the Chinese Room thought experiment.
How would the mind know which one it is?
Maybe your mind is being simulated right now.
