To me, success would be the number of patient's signed up for cryonics, greater cultural acceptance and recognition of cryonics as a reasonable patient choice from the medical field and government.
Maybe starting the Church of the Frost Giants and declaring cryonic suspension to be a religiously mandated funerary practice would work to that end.
I think actually reviving some ice mice might be a bigger step, though.
As an experiment, here's a thread for people to post about things they care about. Specifically, for things that are possible to contribute to, in some way, and preferably, to invite others to join.
Mine is buying and donating highschool textbooks to schools in the 'grey zone' of Ukraine (where the war kinda isn't fought, but few people would be surprised if it started.) I don't deliver them myself, though.
What's yours?
