Don't worry. You're in good company.

> How would this work if, from your perspective, I'm also conscious and not a p-zombie?

It's impossible for me to say that you are conscious. I only watch my own movie. In that movie, others appear to be watching their own movies. Their movies exist only as content in my movie. I cannot say for certain whether or not there really are conscious experiences like mine occurring. All I can say is that I am being given the impression that there are.

> Do I give rise to the world, or do you?

I do. Or at least, something impresses the world upon me. You are a feature of the world that is impressed upon me, and, disappointingly (for me at least), there's no way to confirm it through this movie that I am watching. I am left having to "make up my own mind" about whether or not I choose to believe you are anything but a p-zombie extra, in what is (as far as I can see of the conscious spectrum I am able to perceive), a single screen, single reel movie. But I'm just guessing, hoping, wishing, because that's all I can do from this limited vantage point.

> Do we all collectively create a single world from our consciousness in a "Sandman's Dream of a Thousand Cats" way?

It's a cute idea. Design by committee. Books/predictions of the future seem to have this annoying property of becoming true, lending to this idea. Who knows?

> And if we're all p-zombies except you, why bother arguing with us?

What else am I supposed to do? If you have unimaginable wealth, infinite time and the ability to conjure anything into existence, exactly what are you to do? Perhaps you might dream up what having the opposite of your existence might be, and set about convincing yourself that you are a time-ful, perishable human-being bound by physics and inevitably limited by the finite energy available in the universe, stumped by entropy. Perhaps you even role play as the puppets on the ends of your fingers, while convincing yourself that they're just as real as you are, so you can feel what it's like not to be the majesty of your own lonely empire. What else am I supposed to do, than to go along with it? If we destroy the illusion, we're back to square one - and then what?
