I would question whether you really "feel" that you are the same person you were 10 years ago. 10 years ago you were 10 years younger. Do you "feel" like you are that age now? 10 years ago there were things that you had no knowledge of, that you do now. Just as you are made up of different atoms, etc now, you also have different experiences, and expanded knowledge base, etc. In other words, you are not the same person and you really don't "feel" like you're the same person. However, you are the sentient human entity that was born however many years ago and have accumulated the sum total of knowledge, experience, etc, that you have so far. That said, the observer moments that you have are connected because they're your observer moments and are compared against your base of past experience, etc. They are casually connected if they are moments that are observed in the first place. You're at bat in a ball game and the pitcher throws the ball and you swing and miss and the ball hits you. Each moment in that sequence is related casually and temporally with the other. The moments can be recalled separately but there is still a casual link.

We don't have teleportation yet, especially the demat/remat type (which IMHO is impossible), so I don't see how invoking that is reasonable. Taking a chance to interpret your intent otherwise, I would say that disruption of so-called physical and casual links can happen anytime consciousness is lost, ie sleep, blow to the head, anesthesia, etc. It doesn't support your argument about observer moments being separate in any case.

The implication is obvious: the "machine" is broken. Therefore the conclusions based on the information that it gathers and processes is defective.

Exactly. Broken. No more capable of accurate determination of what is casual, temporal or anything else than a computer is capable of accurate functioning after its been damaged by a virus or some other disruptive event. I had a pocket calculator get wet once and all I could get out of it when I attempted calculations were wrong numbers and sometimes abstract partial digital displays. I no more considered what I was getting from the calculator as valid than I do the perceptions of a patient with "formal thought disorder". The point is their perceptions are wrong, not just different, they're inaccurate and can be demonstrated to be so. It's not good science to base ideas of temporal reality, and other related issues, on someone who's mentally deficient.
