I've posted before about the tragedy of talented people essentially wasting their lives, but I don't see how cryonics is one of those things that people are wasting their time on. Cryonics concerns a Big Issue and if you decide to sign up it doesn't take much time. Once you're signed up you can just forget about it. A few hours of time for a non-negligible chance of significantly expanding the duration and quality of your life.
Tyler Cowen disagrees
My current view is this: one's attention is extremely scarce and limited, as are one's affiliations. Insofar as you have the luxury of thinking "bigger thoughts," those thoughts should be directed at helping others, not at helping oneself. The real opportunity cost of cryonics is not just the money but whatever else you would have done with that intellectual energy.Right. You could entertain yourself for days discovering what Tyler has expended intellectual energy on but I think it should be enough to note that Tyler is a big fan of chess. He's spent enough time playing and studying it that he can follow world championship level matches. I think this is great and all, but it does seems strange that he doesn't approve of people spending time thinking about the length and quality of their lives.
Also if Tyler endorsed cryonics he could probably induce quite a few people to sign up who wouldn't have otherwise, which would count as helping other people wouldn't it?
Tyler's post gets weirder. Robin Hanson responds here.
