Hope, and judging that rotting over weeks or rotting over decades in the worst case will mean they will end up the same way, just slower.
The next step will be (probably destructive) high-resolution scanning of the physical brain structure and then saving the scan data in the hope that one day we will be able to "decode" that data and "run" the brain on some other hardware by emulating it's biology. At least that data will keep fresh much, much longer (potentially). Baby steps to immortality. There's nothing wrong with trying.
Effective immortality will be the most lucrative product ever. Sooner or later we will grow some of us into ghosts and maybe even gods. And they probably will be the same ill-tempered, asshole-gods as all of them are. Well, or not. At least we should try.
Do you really want to die in the same body you were born in? Like a fucking animal?
