Note the Ship of Theseus, while a nice comparison for the title, is not - as the author eventually points out - an appropriate analogy here. A fundamental contribution to the idea of whether the identity of the entity persists or not is the continuity between intermediate states.

In the example given and discussed here the last couple of days there seems to be a process more akin to having an AI create a cast of the pre-existing work and fill it for the new one.
