Nice post but imo the drawbacks youve presented are quite unconvincing and anyone (outside the most extreme) would take any chance at immortality if presented.
Im pretty sure we will figure something out eventually. What it will be is the question.
But ill take a bet on the ingenuity of human kind over promises of any gods, any day of the week.
