- 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."
If a person wants to die, then why wait?
But seriously, you can solve the problem of #3 and #4 by using stem cells to make your brain divide forever, and use computers to store your memory in perfect condition, since brain cells gradually die off.
The problem is... what is "you"? How do you determine whether you are still yourself after a given period of time? Does my solution actually constitute a solution?
Shouldn't we be focusing on a way to scientifically quantify the soul before making ourselves immortal? On second thought, that might not be the best idea.
Well, how do you do it now?
For my own part, I don't think the question means anything. I will change over time; I have already changed over time. As long as the transitions are relatively gradual, there won't be any complaints on that score.
