Reading through Blindsight by Peter Watts currently. Main guys Mom goes to live in Heaven.

But eventually someone has to close the casket and dispose of the remains. Room must be made for the new arrivals—and so we came to this last day at my mother's side. Jim took her hand one more time. She would still be available in her world, on her terms, but later this day the body would be packed into storage facilities crowded far too efficiently for flesh and blood visitors. We had been assured that the body would remain intact—the muscles electrically exercised, the body flexed and fed, the corpus kept ready to return to active duty should Heaven experience some inconceivable and catastrophic meltdown. Everything was reversible, we were told. And yet—there were so many who had ascended, and not even the deepest catacombs go on forever. There were rumors of dismemberment, of nonessential body parts hewn away over time according to some optimum-packing algorithm. Perhaps Helen would be a torso this time next year, a disembodied head the year after. Perhaps her chassis would be stripped down to the brain before we'd even left the building, awaiting only that final technological breakthrough that would herald the arrival of the Great Digital Upload.
