Firstly, consciousness is probably not well-modeled as arbitrary complexity plus X, as the complexity is likely inherent to X, and have a quite specific form. For example, it seems unlikely, on basic information-theoretic grounds, that the notoriously complex turbulent flow of a fluid in a pipe is materially closer to consciousness than laminar flow in that pipe.

Secondly, the burden of proof (or just of showing evidence) rests squarely on the person making the claim that the United States probably has it (whatever 'it' happens to be.) It is hard to do that whan you cannot say, with any specificity at all, what X is.

If your latest post is intended to be a defense of Schwitzgebel's paper, I think you are missing his point. I think he regards the consciousness of the United States counterfactually, and is attempting to show that materialism leads to an implausible conclusion, but he fails to do so, partly on account of the problem I raised in my original post.
