Caledonian: Posthumanity can easily be humanity plus X, where X is some conglomeration of augmentations, backups, and—later—full replacements. This is a “ship of Theseus”. Humanity can easily survive the total replacement and augmentation of its parts because humanity is, at root, the myriad of terminal values that we inherit and learn. You can take the mind out of the meat, but you can’t take the meat out of the mind.
I expect I will live through a continuity of mind to age 1000 and beyond.
I do not expect the 1000 year old me will look or feel recognizably like unmodified humanity except as a deliberate effort.
