> The point of the philosophical zombie is that they don't experience anything, nor do they convince themselves of anything. If they're "experiencing" or "convincing themselves" then they're not philosophical zombies by definition.

The problem is: Implicitly presupposing the existence of philosophical zombies implies the duality gap.

It might as well be that philosophical zombies are mental construct that cannot physically exist, simply because building one will imbue it with 'consciousness' (as, it being the physical copy/simulation, it will be able to simulate also the 'consciousness'), in turn making it non-zombie.
