Cryonics doesn’t necessarily need more male propeller heads. I think it would benefit from more women, married couples and entire families, which would give it the vitality and durability of mainstream social structures like churches. Unfortunately I don’t know how to overcome the “hostile wife phenomenon,” as well as the fact that a commitment to cryonics resists generational transmission.
As an example of the latter, Marce Johnson entered the paleo-cryonics scene in the 1960′s, and she had 40 years to show her children through precept and example that she wanted cryonic suspension for herself. To summarize a long story, despite efforts to raise money for her cryotransport with CI after she developed Alzheimer’s and lost her suspension arrangements with another organization, she died and the daughter with POA over her had her cremated, then informed Marce’s cryonicist friends after the fact, apparently out of spite.
Developed societies in the 21st Century have started to break down in certain ways because we live in “the long run” discounted by people who made bad decisions for us when they ran things decades ago. I’ve seen this happen in cryonics organizations, even though, as Roko speculates, you’d expect that the members who have a stake in cryonics’ success would insist on better performance.
