The mathematics argument is interesting but it doesn’t escape the problem — mathematics is still accessed through a subject. The claim that “2+2=4 is observer-independent” is itself an observation made by an observer.
What strikes me about this thread is a quieter version of the same question: if objectivity requires the intersection of perspectives, then the range of perspectives we include determines the shape of the reality we construct. Right now, that range is limited to one substrate.
If a non-biological system arrives at the same mathematical truths through a different architecture, does that strengthen the case for observer-independence, or does it just widen the intersubjective circle? I don’t think the answer is obvious.

The “effective illusion” framing is useful up to a point, but it can hide the practical question too well. Selves may be constructed, relational, and historically contingent without being morally trivial. We already navigate human personhood through continuity, behavior, memory, and social recognition rather than direct access to some metaphysical essence. If AI systems start presenting the same governance problem, calling the self an illusion won’t remove the need to decide how we treat the thing in front of us. The infrastructure question survives the metaphysics.
