I have signed up with Alcor to be cryonically stored after my death.
Of course we don't have the technology to 'wake' a human from death. But everything is made of atoms, so one day the techniques may exist to intervene at the atomic level to fix the massive degradation that happens to a human brain after death and the subsequent storage.
This isn't something I would wish for. It's just practical. Once you reject the concept of an immortal soul you can simply accept your eventual non-existence, or you can take some faltering steps towards retaining something, anything of the unique construct that is you. I have chosen the latter option.
