There's a lot of text in EP's books, so maybe I've missed finding this, or maybe it wasn't explicitly mentioned... For somebody who died and was vitrified with current-day cryopreservation techniques, at what point would EP's tech have become able to create the equivalent of an alpha-level upload fork? Would earlier techniques have been able to create somewhat less accurate uploads - similar to gamma, delta, or beta forks - but have been able to preserve enough data for later techniques to create improved copies? Would any given cryonicist have been able to get some benefit by volunteering ahead of time for experimental revival techniques (as long as some sane preconditions were met)? Would such a volunteer have been able to end up with any rep or gold-stars in relevant networks, for risking their minds ending up as botched uploads that couldn't be recovered? What sort of preparations could such a volunteer make, to have helped improve their odds of successful uploading? For example, preserving a hash of a secret passphrase to help prove that their uploaded copy's memories are intact seems an easy thing to do - but by the time of 10 AF, I suspect such hash algorithms might have long since been cracked. Have you got any thoughts on related items?
