the reason I posted this article here yesterday is because of the problem that once cryonics will be adopted globally, people will want to get pre-emptively cryopreserved to avoid any further identity degradation. however, if everyone does that, it becomes an existential risk (because no one will be around to keep improving our tech). it’s a massive ultimate group prisoner dilemma. it’s in anyone’s best interest to do it themselves, but we would rather no one (else) does it. and it’s a hard coordination problem. split brain preservation solves this by allowing the whole population to preserve half of their brain while using their other half to keep working towards the goal of reanimating the preserved half. oh, also, happy April Fools day!
I like my comment on the Effective Altruism & Life Extension post ^ _ ^
