What is it exactly that’s so valuable about a person that justifies spending $30000 worth of resources to preserve it? Their “identity”, whatever that means? Their personality, even though it’s probably a dime a dozen? Their acquired knowledge that will be outdated by the time they are revived? What is it that we want to preserve?
What is it that is lost when a person dies, that cannot be regained by creating a new one? I’m not in favor of creating new ones, but new ones are created all the time anyway, so why not learn to live with them? Why do we need to do everything the hard way?
I consider these to be emotional reasons rather than rational ones. Specifically not wanting to die, not wanting certain others to die, and being afraid of death are irrational (or at least it is unclear that there are rational reasons for them). I think there are less roundabout ways to (dis)solve these problems than to engineer immortality. In a more rational culture (which we should be steering for anyway), we would not be so viscerally averse to death.
