This is the subject of David Chalmers’ paper: > > http://consc.net/papers/qualia.html > Chalmers' argument is that if a different brain is not conscious, then somewhere along the way we get either suddenly disappearing or fading qualia, which I agree are philosophically distasteful. But what if someone is fine with philosophical zombies and suddenly disappearing qualia? Is there any impossibility proof for such things?
