"Horn 1" of the dilemma is a Limits to Growth style crisis. It's perfectly possible that such a limits-crisis arrives before the technology needed to expand the limits shows up to save us. (The early signs would be a major recession which never seems to end, and funding for speculative ideas like nano-machines doesn't last.) Or another analogy would be crossing a desert with a small, leaky bottle of water and an ever-growing thirst. On the edge of the desert there is a huge lake, and the traveller reaching it will never be thirsty again. But it's still possible to die before reaching the lake.
I see you think that the technology will arrive in time, which is a legitimate view, but then that also creates big risks of a catastrophe (we reach the lake, and it is poisonous... oops). This is "Horn 2".
My own experience with exciting new technologies is a bit jaded, and my probability assessment for Horn 1 has been moving upward over the years. Radically-new technology always take much longer to deploy than first expected, development never proceeds at the preferred pace of the engineers, and there can be maddeningly-long delays in getting anyone to deploy, even when the tech has been proven to work. The people who provide the money usually have their own agenda and it slows everything down. Space technology is one example here. Nanotechnology looks like another (huge excitement and major funding, but almost none of it going into development of true nano-machines along Drexler's lines.)
I heard that women are difficult to convince when it comes to signing up for cryo. In mentioning cryonics to a dying person, there seems to be a consensus that it's not going to happen. I encountered a post: Years saved: Cryonics vs VillageReach, which addressed my main objection (that the amount of money spent on cryo may be better spent on saving starving children, especially considering that you could save multiple children for that amount of money with high probability whereas you save only one life with low probability by paying for cryo). Now I'm open to being persuaded.
My first instinct was to go read a lot about cryo, but it dawned on me that there are a lot of people here who will want to convince family members, some of them female, to sign up - and these people may appreciate the opportunity to practice on somebody. It has been argued that "Brilliant and creative minds have explored the argument territory quite thoroughly." but if we already know all of the objections and have working rebuttals for each, why is it still thought of as extra difficult to get through to women? If there were a solution to this, it would not be seen as difficult. There must be something that pro-cryo people need for persuading women that they either haven't figured out or aren't good enough at yet.
So, I decided to offer myself for experiments in attempting to convince a woman to sign up for cryo and took a poll in an open thread to see whether there was interest. I don't claim to be perfectly representative of the female population, but I assume that I will have at least some objections in common with them and that persuading me would still be good practice for anyone planning to convince family members in the future. Having a study on persuading women would be more scientific but how do you come up with hypotheses to test for such a study if you have no actual experience persuading women?
So, here is your opportunity to try whatever methods of persuasion you feel like with no guilt, explore my full list of objections without worrying about it being socially awkward, (I will even share cached religious thoughts, as annoyed as I am that I still have them.), and I will document as many of my impressions and objections as I can before I forget them.
I am putting each objection / impression into a new comment for organization. Also, I have decided to avoid reading anything further on cryo, until/unless it is suggested by one of my persuaders.
Well, have fun getting inside my head.
