1) I value my life more than the lives of 4-8 strangers, as demonstrated by the fact I haven't committed suicide to donate my organs. Based on the reading I have done so far, I can't realistically assign cryonics a greater than 10% chance of actually working, so the question is whether I value my life (discounted by a factor of 10) more than the lives of 4-8 strangers, which I don't. If Omega told me cryonics was guaranteed to work, I would sign up.
2) Making money without a high school degree, special skills, or Eliezer-level intelligence is more difficult than I think most highly-trained people realize. I'll PM you, though.
3) I would assign a very high probability to a Singularity within my lifetime; I would also say I am 85% confident that if the Singularity does not happen in my lifetime, it will not happen. If the 21st century closes without any of the advances we anticipate, that would dramatically increase my estimate that they are impossible.But I've conceded to Alexai that even discounting for all this, it is probably still worth it; if I can resolve the other issues I will sign up.
Making money [...] is more difficult than I think most highly-trained people realize.
The cost of a life insurance policy that covers cryonics is, I think, much less expensive than most people realize. I did the math myself recently and I think it came out to, conservatively, $500/year, which I could easily afford on a retail / call center paycheck. It is definitely worth your time to at least look in to the exact cost for you personally. You're young so you're probably looking at significantly less than me.
Disclaimer: I'm not signed up either; I'm currently trying to sort out why. Discovering it was that cheap has removed a very major obstacle that I wasn't aware of, however.
An exercise:
Name something that you do not do but should/wish you did/are told you ought, or that you do less than is normally recommended. (For instance, "exercise" or "eat vegetables".)
Make an exhaustive list of your sufficient conditions for avoiding this thing. (If you suspect that your list may be non-exhaustive, mention that in your comment.)
Precommit that: If someone comes up with a way to do the thing which doesn't have any of your listed problems, you will at least try it. It counts if you come up with this response yourself upon making your list.
(Based on: Is That Your True Rejection?)
Edit to add: Kindly stick to the spirit of the exercise; if you have no advice in line with the exercise, this is not the place to offer it. Do not drift into confrontational or abusive demands that people adjust their restrictions to suit your cached suggestion, and do not offer unsolicited other-optimizing.
