Would it not be possible to harness the enormous computational speed
of nanocomputers to provide an extremely good digital simulation of these
continuous biological systems? 

Note also that if we can devise an accurate model of the biological
processes involved in memory and the "machinery" of thought then we might
be able to identify those essential elements that encode our mind.
It might then be possible to relax the requirements for successful
cyronic suspension to provide preservation for fewer biological structures.

Personally, I think that uploading affords the most potent form of
