OK. > What are "relevant" memories. The same you need to conserve in case of any operation. What you and your family needs to say to your friend that the operation (digital brain transplant) has been a success, or to say, the Earth Mars teleportation device works fine. Nobody can know with certainty its substitution level. Maybe rich people will teleported themselves well below the substitution level by precaution if they can afford it (the number of bit will be in general bigger). > What are "all your psychological traits”. 2147 Breaking News: Alfred has used a very cheap teleportation device to go on Mars. He seemed OK and claimed he has not changed, but his wife believes he lost his sense of humour. An inquest revealed that the the substitution level chose by the candidate were indeed not always used, and very often the society used a much higher level. Many users lost some psychological trait, like sense of humour, or some memories, or even the ability to have REM sleep. > The problem is there is no level of description where this is invariant > because "this" ill defined. No, it is well defined by the mechanist assumption. It just that we cannot know for sure our description level. For the biological body, the living creature reproduce themselves at some description level (encoded in the DNA), it works. For a brain,, to conserve the psychological identity, the copy needs some level of accuracy much more precise than a piece of DNA code, but, by definition of digital mechanism it exists. The non constructively is not a problem in the reversal reasoning, because in the arithmetical reality, you are “reconstituted” (to be short) at *all* level of description, and the physical laws are reduced to the statistics on the first person person experience related to the infinity of computations supporting the your current state. > And invariant under what? Duplication? That depends on the step of the reasoning. At step 1, your consciousness is "preserved correctly” in the operation of scanning+annihilation together with the reconstitution. > Time evolution? 3p time evolution, that is precisely what your first person reality is not dependent upon (step 2). > Different threads of the UD? Yes, at step 7, you are supposed to understand that your next first person state depends on all the continuation of your computation at the right substitution level and below, that are realised, in the relative way, in the arithmetical reality (also called the standard model of the Arithmetical Theories). The Arithmetic Reality determines in this sense an internal many-histories interpretation of Arithmetic, and if both mechanism and quantum mechanics are correct, they should be the same, which is testable, and tested, assuming the physicists agrees on QM and on its quantum logic(s). They are nuances here made by the physicists, which are welcome, because the universal machine introduces some nuances too: we get three quantum logics.
