OK, great, we're on the same page. Now my next question is, why can't a synthetic organism (like one made of silicon that you have allowed may be alive, given the proper organization) have subjective experience? Again with the usual reminders that carbon-based and silicon-based life forms would both be subject to identical electromagnetic/nuclear/gravitational forces.
