It may be a useful summary of Special Relativity and General Relativity for those who knows First Order Logic (FOL). Is is W function computable? In that case comp refutes GR. His notion of observer fulfills the (usual) Sigma_1 definition, and, like almost everyone, he uses the identity thesis (of cognitive-science/philosophy- of-mind) implicitly. Of course this remark is very general, it works for such formal approach, but also on Tegmark's mathematicalist approach, etc.
