If potential is key, I say keep the context of the MAID process but instead of outright death make it cryonics. Plus other potential relevant volunteer stuff and organ donation stuff lined up. Even if the initial cryonics technique is not even close to viable, other stuff could be transformative. If cryonics has any chance to work, things will get appreciably better in 300-or-so years right?

Hopeful worst is my brain in a jar mostly playing VR and sometimes knitting yarn via robotic arms. Lots of ways it could be better. Also unlike traditional cyborg stuff with all-machine life-support, I would like to still have a complex microbiome if not taking it further with symbiosis.
