I'm being pulled off to bed, but from my skimming this looks like a very, very helpful critique. Thank you for posting it; I'll peruse it as soon as I'm able. One note: I did note after posting this, but too late to make a meaningful change, that "we should support cryonics less" is rather a ridiculous notion, considering the people I'm talking to are probably not the same people who are working hardest on cryonics. So: oops.
