I'm saying that cryonics implies taking a certain degree of responsibility for the future. That's not an argument in favor of it working. It is an argument in favor of it being a positive thing overall, irrespective of it working. It provides selfish incentive for caring about the fate of future generations. Since we are trying to establish betting odds and what is a fair price for cryonics, all the externalities need to be taken into account. A world with cryonics is better off than a world without it.

I disagree that company failures or war are unrelated to education levels (or quality). A well educated populace should be more resistant to and capable of avoiding war, and more capable of solving and preventing financial problems. One specific thing for cryonics trusts to do is offer scholarships to those pursuing peace and financial stability as educational specialties.

Natural disasters can be avoided to some degree by careful selection of location. Alcor is based in Arizona partly because of the lack of earthquakes. Hurricanes and tornadoes be protected against by using a monolithic dome. LN2 shortages can be protected against by having a large bulk storage tank on site, and using efficient insulation.

That said, the most desirable solution (because it addresses all the different sources of risk simultaneously) is to accelerate the development of revival technology to whatever degree is possible. Maintaining high education levels is critical to this, as is spending money on brain and body repair research. This produces a very large positive externality.

The strategy that works best is to make sure that multiple things have to go wrong in order for a critical failure at each critical point. That is how disasters are prevented in e.g. nuclear facilities. It's expensive and painstaking, but it is a case where throwing money and competent engineers at the problem actually works.

Your argument for cryonics having a low probability of working apparently assumes no one has done or will have done this, despite the obvious fact that they have an extremely strong interest in so doing. And you accuse accuse me of hand-waving?

I'm saying you're making an arbitrary link without substance that suits your purposes. Cryonics does not imply or require actually caring about the future in any significant way. All cryonics implies is a desperate desire for self-prolonging. The process of maintaining someone in a frozen state definitely has negative consequences for the environment. This is not the act of someone trying to help the future. It's the act of someone who puts his own desires over the well-being of the future.

You're crazy to think that a well-educated populace will avoid war. Americans are well-educated and we've been involved in wars nearly non-stop since we were founded. As for companies failing, the last several years have shown us that educated people will happily destroy companies for personal gain (not that we didn't already know this).

Natural disasters can be made less probable by choosing an appropriate location, not avoided entirely. An asteroid can hit Arizona as easily as New York. And earthquakes can basically strike anywhere. They're simply more likely in certain areas.

My argument for cryonics' low probability is based on the fact that so many things can go wrong over such a long time frame (we don't engineer nuclear facilities to last for thousands of years). The fact that some people have pursued cryonics is in no way proof or even evidence of it's feasibility. How many billions of people pursue religion for the same reasons? The desire for self-preservation often results in irrational behaviors.
