Did you know that though vitrification, state of the art cryogenics researched have achieved to preserve 100% of the structure of a pig brain?
The science for preserving with 100% accuracy your brain is already here.
Those scientists use this technology to preserve organs and the cryogenic property is just a side effect. We simply need an enterprise that reproduce their results on human brains (shouldn't be different than a pig brain) and that commercialize it.
The process replace blood and other brain fluids with a chemically toxic fluid.
Which means that while the structure is preserved, any attempt at resurrecting the brain would need an advanced technique that would gradually replace the toxic fluid with fresh blood/Cerebrospinal fluid and the replacement should be 1) total 2) the replacement process should not destroy structure.
Intermediary new kinds of fluids in the process might make the transition easier/safer.
Once your brain is filled with the right amount of blood and of cerebrospinal fluid and has no toxic fluid left in order for the brain to function, a minimal level of hormones / molecules will need to be dispatched in the brain.
Once all of this is achieved remains the problem of interfacing your brain with a new body.
Happily once cryogenized (technically doable today) resolving all the others necessary steps will take time and you will have time.
With not so much money you could be kept vitrified (not frozen) for a millennium or two.
It seems unlikely but still is a possibility that an advanced civilization could not by design uncryogenize you without affecting your structure. But the structure being preserved they could make a copy of you (numeric or not), while this has its lot of metaphysical issues It's still a path far more hopeful than eternal death.
As a reminder our normal life is mostly as metaphysically weird as most of our cells are replaced every 5 years? What's define YOU is totally unclear and continuous
