Are you questioning if physics is computable? Even if it is not fully, we must be able to approximate it quite well. Suppose we scan more than just the person, but a local environment around them and simulated the whole box. The update that occurs as the person sits in the room involves them considering their own existence. Maybe they create art about it. If the simulation is to produce accurate results, they will need to feel alive to themselves. We agree we can simulate an explosion and get accurate results; if we can’t get an accurate simulation of a person, why?
