Yes, I agree there are unresolved issues. There simply is no widely accepted way of reasoning about subjective experience. Given this, it seems more unreasonable to assert that simulation of subjective experience is absolutely impossible (prior probability=0). Yet even if we give a small prior to it, due to the overwhelmingly great number of human-like experience simulation theory suggests, SIA would push its probability to near unity. So many SIA supporters would make the above-mentioned assertion.
