Never came by this draft. Is it new? (Though he has been working with it for quite some time..) I will take a look at it. But beforehand, my general view on simulations/emulations, is that even solely non-agency statistical simulations of an agent's behaviour, if precise enough, would contain what matters on suffering/pleasure. Memories feelings, thoughts and so on would be all shattered throughout many, many variables, but the correlations which would have to hold between all of these might still guarantee there would still be a (perhaps sentient) agent there.
