personhood and copy problem - yasufumi-nakata/mind-upload GitHub Wiki
Even if they look the same, whether they are the same person is a different matter.

This page is a wiki that organizes the copying problem'' and authenticity'' that often come up in Mind-Upload discussions from the beginning. Before memorizing the proper nouns of philosophy, I aim to understand why this issue does not escape from technology.
This page provides easy-to-understand explanations, but it is not a page to draw final conclusions about the person's identity. Clarify what remains unresolved.
- Wiki: Basics of WBE - The position of this issue can be confirmed from the overall picture.
- Wiki: How to read claims and evidence - Compensates for how strong L4's identity claims are.
- Wiki: Identity assessment and continuity test - Organize the philosophical issues back into the pre-registered test design.
- Wiki Home - You can return to other basic pages.
- Even if someone looks similar in behavior, that alone does not confirm their identity.
- In situations where there are multiple copies, it is not automatically determined which one is the real person.
- Therefore, in Mind-Upload, we treat how to verify continuity as a separate issue.
- There is no agreement on the conditions under which two persons can be considered as "the same person."
- The conclusion will change depending on whether you emphasize psychological continuity, causal continuity, or phenomenal consciousness.
- It is also unproven whether continuous transition designs adequately protect identity.
Even if you speak exactly the same way, share the same memories, or react in the same way as someone else, that alone does not mean that you are the same person. At Mind-Upload, we treat performance matching andidentity assertion as different levels in order to avoid blurring this difference.
| Question | Why is it difficult |
|---|---|
| If I could share the same memory, would it be me? | This is because the reproduction of memory and the continuity of experience may not be the same. |
| If there is only one copy, it is the person himself/herself | If two were created, it would be difficult to determine which one is the real person using the same logic. |
| Is it safe to replace it little by little? | Continuous transition seems intuitively strong, but it remains to be seen whether it is a sufficient condition. |
| Thinking | What to focus on | Remaining questions |
|---|---|---|
| Static copy | To copy a structure or information at a certain point in time. | If you have multiple copies, you won't know which one is the real person. |
| Continuous migration | To take over processes and interactions without interruption. | It is still unproven whether continuity is a sufficient condition for identity. |
Returning this point to engineering, it is not enough to simply look at whether things are very similar. It is necessary to examine the continuum of memory, values, learning history, and response to changes in conditions through pre-registered tests. In other words, rather than leaving the philosophical discussion as it is, we move toward definingwhat kinds of failures would cause us to suspend our claim of identity.
If you want to look at the introduction to test design first, Wiki: Identity Assessment and Continuity Tests is a supplementary course.
You can check here how to treat this issue as a theoretical frame.
