I don't know if anyone picked up on this, but this to me somehow correlates with Eliezer Yudkowsky's post on Normal Cryonics... if in reverse.

Eliezer was making a passionate case that not choosing cryonics is irrational, and that not choosing it for your children has moral implications. It's made me examine my thoughts and beliefs about the topic, which were, I admit, ready-made cultural attitudes of derision and distrust.

Once you notice a cultural bias, it's not too hard to change your reasoned opinion... but the bias usually piggy-backs on a deep-seated reptilian reaction. I find changing that reaction to be harder work.

All this to say that in the case of this tale, and of Eliezer's lament, what might be at work is the fallacy of sunk costs (if we have another name for it, and maybe a post to link to, please let me know!).

Knowing that we will suffer, and knowing that we will die, are unbearable thoughts. We invest an enormous amount of energy toward dealing with the certainty of death and of suffering, as individuals, families, social groups, nations. Worlds in which we would not have to die, or not have to suffer, are worlds for which we have no useful skills or tools. Especially compared to the considerable arsenal of sophisticated technologies, art forms, and psychoses we've painstakingly evolved to cope with death.

That's where I am right now. Eliezer's comments have triggered a strongly rational dissonance, but I feel comfortable hanging around all the serious people, who are too busy doing the serious work of making the most of life to waste any time on silly things like immortality. Mostly, I'm terrified at the unfathomable enormity of everything that I'll have to do to adapt to a belief in cryonics. I'll have to change my approach to everything... and I don't have any cultural references to guide the way.

Rationally, I know that most of what I've learned is useless if I have more time to live. Emotionally, I'm afraid to let go, because what else do I have?

Is this a matter of genetic programming percolating too deep into the fabric of all our systems, be they genetic, nervous, emotional, instinctual, cultural, intellectual? Are we so hard-wired for death that we physically can't fathom or adapt to the potential for immortality?

I'm particularly interested in hearing about the experience of the LW community on this: How far can rational examination of life-extension possibilities go in changing your outlook, but also feelings or even instincts? Is there a new level of self-consciousness behind this brick wall I'm hitting, or is it pretty much brick all the way?
