Can we please stop using cryonics as a rationality example? It seems pretty clear to me that a thoroughly altruistic, rational person would not spend their money on cryonics. Signing up for cryonics is only rational if you pass some threshold of selfishness.
If you don’t believe me: why does your cryonics example involve someone not signing up their son for cryonics? Why aren’t you chiding him for not signing up random other people? Well, because there are better ways to help random other people. You’d only help your son first if (a) he was person you could most efficiently help out in the set of all sentient beings (present and future) or (b) you were selfish. (Not especially selfish by most standards. But you’re certainly not treating everyone equally.)
