One of the old standard topics of OB was cryogenics; why it's great even thought it's incredibly speculative & relatively expensive, and how we're all fools for not signing up. (I jest, but still.)

Why is there so much less interest in things like caloric restriction? Or even better, intermittent fasting, which doesn't even require cuts in calories? If we're at all optimistic about the Singularity or cryogenic-revival-level-technology being reached by 2100, then aren't those way superior options? They deliver concrete benefits now, for a price that can't be beat, and on the right time-scale*.

Yet I don't think I've seen Robin or Eliezer even once say something like "and if you don't buy the benefits of cryogenic preservation, why on earth aren't you at least doing CR?".

* Assume we're in or close to our teens - as many of the readers are, and would live to to 80 or 90 due to our family background; that pushes our death date out to ~2080; assume CR/IF deliver less benefits in humans than in lower organism, say, 20%; that gets us another 18 years, or to 2098, which is close enough to 2100 as to make no difference.
