- Our not wanting to die is a bit of irrational behavior selected for by evolution. The universe doesn’t care if you’re there or not. The contrasting idea that you are the universe is mystical, not rational.
- The idea that you are alive “now” but will be dead “later” is irrational. Time is just a persistent illusion according to relativistic physics. You are alive and dead, period.
- A cyber-replica is not you. If one were made and stood next to you, you would still not consent to be shot.
- Ditto a meat replica
- If you believe the many worlds model of quantum physics is true (Eliezer does), then there already are a vitually infinite number of replicas of you already, so why bother making another one?
Terminal values and preferences are not rational or irrational. They simply are your preferences. I want a pizza. If I get a pizza, that won't make me consent to get shot. I still want a pizza. There are a virtually infinite number of me that DO have a pizza. I still want a pizza. The pizza from a certain point of view won't exist, and neither will I, by the time I get to eat some of it. I still want a pizza, damn it.
Of course, if you think all of that is irrational, then by all means don't order the pizza. More for me."
Regarding 1, all base values are irrational products, from culture and evolution. The desire not to go torture babies is due to evolution. I don't think that is going to make your father any more willing to do it. The key argument for death being bad is that his actual values will be less achieved if he dies. The standard example when it is a family member is to guilt them with how other family members feel. Presumably your father has lost people. He knows how much that hurts and how it never fully goes away. Even if he were actually fine with his existence ending (which I suspect he isn't) does it not bother him that he will cause pain and suffering to his friends and family?
I expect that new values can be decided by intelligent agents.
(Also, distinguish "irrational" and "arational".)
