As of right now the promise of cryogenics is analogous to snake-oil and various forms of alternative medicine. Surgery is something that works, we know why it works, how it works, how to do it again and again, how to gage the probability of success in particular cases even. In other words surgery is something on par with science and engineering. Comparatively the promise of cryogenics is like science fiction and magic.

I'm all for people engaging in cryogenics, alternative medicine, snake-oils, gods and magic if they have the money and desire but these sort of silly arguments and rationalizations about them I do not understand at all.
