I would have thought that this "limit" could be regarded as indefinite as far as
cryonics is concerned. If someone remains cryopreserved for any appreciable 
fraction of a million years this tends to suggest that reanimation is becoming 
increasingly unlikely as time moves on.


The forces of mis-directed commerce and regulation may produce periods of 
technological stagnation, but these are likely to be hundreds rather than 
thousands of years.
