I came here to comment this same thing. I had this idea as a laugh, but I'm taking it more and more seriously as time goes on. There are very confident statements made here that I don't think a conscious human could sincerely claim. If the author isn't taking the piss (and no indication they are) then I strongly suspect they don't have consciousness.

Kind of ironic given the bit of the article that focuses on P-Zombies and how they don't work because they have to be indistinguishable. Well, what if P-Zombies are real, and they are distinguishable, it's just not obvious because the P-Zombies grew up in a world where people talk about consciousness and lots of people around them have it.
