- 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."
I may have been imprecise with terminology in that comment, but the query is coherent and involves no such conflation. The referent of "belief" there is "belief about whether one ought to indefinitely extend one's life through methods like cryopreservation", which is indeed an expression of values. Your judgment of the merit of my comparison is hasty.
The conflation occurs within the impricision of terminology.
Does this so called "belief" control anticipated experience or distinguish between coherent configurations of reality as making the belief true or false?
Even if the thoughts you were expressing were more virtuous than their expression, the quality of your communication matters.
