I see cryonics as a kind of insurance policy. Fitting, since it is literally a life insurance policy that funds it. As I continue to live on to see technology improve at an exponential* level, I can continually refine my options as needed. If I live to be 60 and by then, the cost of cryonics has dropped to $10 (which is admittedly an optimistic estimate), I can take the money I've paid in and withdraw both it and the interest it has accrued. If instead the cost has not dropped, or in fact has increased or even if the prospect of cryonics has disappeared entirely, I can still take the money and use it on expensive wine. :) If I have a heart attack next week, I will have lived out my last few days with the comfort that my cryonics is funded and the probability of my brain decaying immediately is far greater than zero and that of my being revived someday is not approximately zero.
