This does, however, put me into disagreement with both Robin Hanson ("More likely than not, most folks who die today didn't have to die!") and Eliezer Yudkowsky ("Not signing up for cryonics [says that] you've stopped believing that human life, and your own life, is something of value").

I ... don't think it does, actually. Well, the bit about "most possible futures are empty" does put you in conflict with Robin Hanson ("More likely than not, most folks who die today didn't have to die!"), I guess, but the actual thesis seems to fall into the category of Eliezer Yudkowsky's "you've stopped believing that human life, and your own life, is something of value" (after a certain point in history.)
