I don't know the answer to your question, but my guess is that non-intrusive periodic backups, if and when when implemented, will not use this particular technology. Storing about 10^30 bits of data per backup is unlikely to be the way to go, given that most of them will be redundant.
That's a good point, shminux. But don't you think that the entire organ needs to be scanned at high resolution first before storing a compressed copy?
To all my physicists in the house, will it ever be possible for a device to scan the contents of a human head at the molecular level (say, 5 x 5 x 5nm) while the subject is still alive? I don't have a physics background, so if you could also just point me to the materials I need to read to be able to answer the question, that would be wonderful as well.
The background: I want to live to see the far future and so I'm researching the feasibility of alternatives to cryonics that'll let people "back up" themselves at regular intervals rather than at the point of death. If this is even theoretically possible then I can direct my time and donations towards medical imaging researchers. If not then I'll continue to support cryonics and plastination research.
I'm looking forward to your responses!
