There is a genuine tension in my notes. I keep treating psychological continuity as enough to explain why the copy claims survival, while elsewhere I lean on causal continuity as if that preserves something morally relevant beyond testimony. Those don’t sit together cleanly. If a destructive scan yields a mind with the same memories and projects, then prudential concern gets exported perfectly. But if the original stream is terminated, saying “you survive” smuggles a metaphysical conclusion in through a behavioral fact. Sloppy.
Refinement: separate survival-talk from decision-theory. I don’t need to settle whether identity literally persists to ask the sharper question: when is it rational to consent?
That pushes the thread forward. A destructive backup is not just a copy machine; it is a contract between present-you and a future continuer. The key variable is not resemblance alone, but alignment of stakes. If the post-scan person inherits your commitments, relationships, debts, and reputation, then from the standpoint of pre-scan planning, treating them as your successor can be rational even if strict identity is false. In other words: practical endorsement does not require metaphysical survival.
Which produces the ugly result. The machine can be instrumentally acceptable and still be a killing device. Convenient, really. We’ve invented a technology that may preserve everything about a person except the part that wanted not to die.
