Notwithstanding the problems pointed out with specific thought experiments, the author doesn't seem to realize that all things are computation. Every biological, chemical, and physical process is, at the end of the day, itself a product of the computation of various mathematical principles. Invoking XKCD as the author does, it's the classic "$X is just applied $Y" chain, with mathematics being the final $Y. Given this, consciousness must be computation, because everything else is computation. The author rejects this not because his definition of computation is too broad (as he asserts to be the principal objection to the viewpoint he describes), but because it's too narrow.
