Thanks for saving me from karmic hell, but I still don't see the conflict. I seem to follow the Vinge version, which doesn't appear to be proscribed.

I may have been too categorical, obviously one can make all the predictions he likes, and some with a high percentage of certainty, for instance "If cryorevival is possible then post singularity it will be trivial to implement" but that still doesn't give us any certainty that this will be so, for instance a post singularity paperclip maximizer would be capable of cryorevival but have no interest in it.
