Now some further remarks on form vs. function. I and others have pointed out previously that, if one must choose between preserving structure and preserving function, there is no easy or reliable way to decide. So far, all cryonics organizations have chosen to emphasize function over structure. But Drexler and others have noted that, from a nanotech repair point of view, the latter might be better. Doug Skrecky also has some recent comments in this area.
Further investigation is on our agenda.
Not the results, to any important extent-from a cryonics point of view, cryopreservation of spermatozoa has little or no relevance. Needless to say, it is doubtful that even Bill Gates could keep many teams of surgeons on constant standby, even if the technical problems could be solved. Several decades ago, that seemed hopeful to many, including me. But such reports have been scant, and confirmation by other investigators even more sparse, and the criteria of long term survival not always clear. So perhaps we should take an intermediate stance.
