I didn't create this concept, either. And, like I said, there are materialists who believe that the center where perception goes to is on the left half.

The fact that they can do these things prove that they can do these things, just like a robot can. And we know that a robot doesn't have an observer. Any being can perfectly react to stimuli without qualia that represent them.
By definition, an observer is not necessary for a brain to be functional. This is very easy to imagine.

We know a robot is not the same as a human because it doesn't have the higher level processing that we do in the neocortex.
