Anthropologists tell us that home sapiens are concerned about "others," even after they die.
In settled (as opposed to nomadic) societies this concern seems to catalyze beliefs, rituals, and institutions, taking many forms.
This is so even though the ancestral dead have no further empirical or "use value."
To restate, the ancestral dead are, obviously, the origin of all knowledge, concepts, and values to the living. They transferred all the information. But the "value" of the "source of information" is abruptly terminated once they are dead.
Is this "care for the ancestral dead" an emotional or a rational reaction? If AI captures human consciousness, would it have to model "care for the dead"? How could it rationally go about this?
