A V2EX User’s Philosophical and Technical Argument for Digital Immortality Feasibility, Consciousness Continuity, and a “Ship of Theseus” Transition Plan
English summary
A V2EX user argues that digital immortality is both physically permissible and necessary for human civilization. The post claims that consciousness continuity is logically guaranteed as long as the experience remains logically connected, regardless of substrate. A practical “Ship of Theseus” approach is proposed: a mature brain-computer interface would first let a silicon auxiliary brain coexist with the biological brain, synchronizing all memories and structure, then seamlessly take over after biological death. The author also speculates that if digital immortality had already been achieved, society might use a simulation-based moral exam to filter candidates before granting them silicon access—hinting we might already be living in such a test.
Chinese summary
V2EX 用户论证数字永生物理上可行且文明层面必要。论述称，意识连续性是逻辑上的连续体验，不依赖物质载体，只要逻辑连贯，“你”就是“你”。作者提出“忒修斯修船法”过渡方案：待脑机接口成熟，先用硅基辅脑与肉脑共存、全量同步记忆与结构，肉脑死亡后硅脑无缝接管，再将硅脑迁移至仿生躯体。此外，作者推测若永生已成现实，社会可能以模拟考试筛选候选者，并暗示我们或许已身处这样一场考试中。
Key points
The author asserts digital immortality is feasible because the universe permits the existence of a conscious self regardless of carbon or silicon substrate.
作者声称数字永生可行，因为宇宙允许意识自我存在，不论载体是碳基还是硅基。
Consciousness identity is preserved by logical continuity of experience, not by physical continuity; a seamless transition via a gradual “Ship of Theseus” co-existence of biological and silicon brains is proposed.
意识同一性由体验的逻辑连续性保证，不依赖物理连续性；提出通过肉脑与硅脑逐步共存、无缝过渡的“忒修斯修船法”方案。
Digital immortality is framed as necessary to end the suffering of death, preserve unique human experience, enable interstellar travel, and coexist with future AGI.
指出数字永生对结束死亡痛苦、保存人类独特经验、支持星际航行以及与未来 AGI 共存是必要的。
The post speculates that if digital immortality already existed, a moral examination in a simulated pre-BMI world would likely be required, and suggests we might currently be inside such a test.
文章推测若数字永生已实现，可能会通过模拟无脑机接口世界的道德考试来筛选永生者，并暗示我们当前可能正在经历这样的考试。
