So... Grampa finally croaks at the age of 101. Hasn't been able to see, hear, taste, smell, or think straight for the last 15 years. When his magic soul is divinely uploaded to a new, angelic, ether-based model, is his consciousness just like it was when he died? Senile, socially disengaged, and slow to understand anything going on around him? Or, as many believe, would it be transformed to its former glory, when gramps was a young adult.
O.K... Now think about how differently you looked at the world; the skills, interests, and personality you had when you were much younger. Grandfather is a categorically different person from the vital young man he once was (he'd probably yell at him to get off his lawn if they met). So, in what sense would that angelic being be the same guy that died and not more so a recreation of somebody that existed 75 years ago?
I just can't see how the Judeo-Christian concept of an afterlife is anything but a big pile of paradox.
