If we assume there is no AI superintelligence trying to bring you back, what's your estimate of the ratio of the probabilities of information-theoretic death given cryonic preservation and absent cryonic preservation?

I don't know enough about nanotech to give a good estimate of this path. The brain uploading path via brain scans is reasonable given cryonics and, of course, hopeless without it.

Do you think it's an equally powerful signal to the superintelligence you posit? Perhaps given that in part by signing up for cryonics I have probably changed my brain state to more want to outlive my natural death and this would be reflected in my writings.
