Q: Do you really think it will become possible to cure every disease, even reverse the effects of aging, and repair all freezing damage as well --?
A: It isn't necessary to wait till 'every' disease imaginable is cured, all at one stroke. What you really need to do to make cryonics itself work is to cure or prevent freezing damage. And as previously indicated, there is reason to think nanotechnology will be capable of cure or repair, while reduction of damage has already been achieved, and our research is ongoing.
As improved freezing methods, or improved methods of "vitrification" are developed, there will be less burden on future technology, hence probably earlier revival. "Vitrification" means formation of a glasslike solid as temperature falls. This stops the formation of large ice crystals that may damage tissues.
No, we don't expect an instant cure of every possible disease overnight; we expect that what we see happening around us every day will continue -- knowledge and technology will keep growing, and illnesses will keep becoming curable, one by one. When the particular problem that required cryonic suspension is solved, the patient will be revived -- and made healthy and well.
The fact is, scientific knowledge is growing rapidly, and with an ever-increasing rate of growth; technological breakthroughs are occurring almost daily; rapid progress is clearly taking place in every field, and cryonics is no exception. We are guardedly optimistic - because we have good reasons to be.
