OK. (and then step 8 explains why the initial universe is no more useful, the arithmetical UD is enough). Also, it is perhaps always one next 1-observer moment, but also always an infinity of 3-observer moments. The UD is terribly redundant, and anything it does, it will repeat it infinitely often. A compactification of it looks really like the border of the Mandelbrot set. The closer you look, the more complex it appears. http://www.youtube.com/watch?v=g9iOORSU9zk > Once built then > there would exist at least one consistent extension of me (including > the milky way if this level of entanglement is to be necessary to > adequately ensure this is the most probable next state of my > consciousness) in the UD which will enable me to experience my next > Observer Moment (after the last one in Brussells). Infinitely one. "in the UD" means "third person describable (in principle) by an outside observers". The probable next 1-moment is a winner among those 3-moments. > > >> But from your current "here and now" experience, you have to expect >> the most probable relative computation(s) (among all generated in the >> UD going through your current state.

This is like your delay > scenario in the SANE paper. Yes, and we cannot be aware of those delays. And the step 8 discharges the need of the "robust concrete universe".

I’m really sorry but I’m not understanding this. It is normal. You need to read Gödel 1931, Löb, 1955, Solovay 1976, + Everett 1957. (and the needed books or courses). It is why I separate UDA from AUDA. UDA needs some amount of familiarity with computers, but AUDA needs mathematical logics (which is not very well known). > > >> We have to justify the stable appearance of the current wetware (or >> whateverware) from our being software constructs (numbers, relative >> variable numbers) executed (in the math sense) by infinitely many >> universal machines. >> In a sense, below our substitution level, all universal machines >> compete. > > Yes I think I understand this bit because you are saying that that > there may be (infinitely) many UD’s (already existing for all we > know)? Any UD generates all other UDs, infinitely often.
