What I find most interesting about it aren't the kooks and weirdos that are into cryonics, but the visceral reaction that your average Joe has to the idea.
The average opinion about cryonics seems to range from 'That is impossible' to 'why would you want that?'. But if you ask that same average Joe about a cure for cancer they're likely to say that it's been done and the rich just horde it for themselves.
It's weird that they don't see things like cures for cancer, regrowing organs, age slowing drugs etc... as all part of a pathway to the same thing which is a technological solution to many causes of aging and death.
Unlocking the ability to grow and store organs or even just store donated organs cryogenically is highly desirable from an economic standpoint has it frees up so many resources (1pc of US GDP is spent on dialysis alone) so if there's a technological means to do it we're going to find a way sooner or later.
And once we've found a way to freeze and revive large parts of the body it's just a gruesome divide and conquer from there...
