The its is neither the UD, nor the universe, but the observer (you). The observable part of the universe that the observer is observing here and now is determined by the collection of computations (in the UD) going through the state of the observer here and now.

Then take into account the first person indeterminacy and its invariance for huge computation delays, its invariance for the real/ virtual change, well, all the first person invariance described in the first six steps of the UD Argument. You can see, then, that, whatever experience you are doing in your present, your subjective future is determined by the infinity of computations made by that UD and which go through the computational state of your mind during the experiences. OK? Bruno OK - I think. The indeterminacy arises because among the computations that the UD is performing there are many realizations of universes in which you have the same mental state. Universes, or pieces of universes, and/or just dreams, etc. OK But the continuations of those computations are not identical since they are in different universes. OK. But it seems that this requires some way of identifying what part of a universe is you. How are you picked out? By point of view (in the general sense of local interaction)? Yes. The picking out is made by the first person point of view. There is no third person ways to make the picking out, but the observer himself will do it from his first person point of view. He will feel to be the one who has survived. This will require indeed a local interaction. If my consciousness supervenes only on the couple ME+MILKY-WAY, I will survive in the infinity many UD-emulations of the couples ME +MILKY-WAY (done at the right level or below). I will obviously not be conscious in the extensions where I do not survive. So, quasi- tautologically, I will be picked out on the domain of continuations where I do survive. Note: this introduces a first person non-cul-de-sac form of immortality, which is the reason why it is handled by the Bp Dt hypostase. The Dt assures the existence of at least one extension, as we know it exist in the UD*. It is necessary given that G, which represents the believed machine's logic of belief, does not prove Bp - Dt (but G* proves it, G* represents the true machine's logic of belief). Of course, biologists provide clues that the level is possibly high (neurons, glial cells, chemical brain product concentration), but strictly speaking we cannot prove that a level of substitution is correct. We have to trust or to distrust the doctor, and the doctor has to be honest in saying that he is just guessing, and that the operation is risky.

DM - ~DP DP - DM, So DP - ~DP, so ~DP. Bruno This confuses me. When you say the universe is not computable, you mean it is not the process of computing a function. But you think it is generated by a UD. Right? In other words, you are saying what a UD does is *not* a computation. I think you are forgetting to take into account the first person indeterminacy. Your probable next first person state in indeterminate, and the domain of indetermination is all the third person states equivalent (in the third person doctor sense) with the state of your current body (at the right level or below) generated infinitely often by the UD. The physical laws have to be retrieved from that indeterminacy on that domain, and there is no reason why your statistical experience or physical reality is computable. The UD does (an infinite) computation, but the universe results from an internal and relative statistics on all computations. It remains possible that somehow a computation wins the game, but if that is the case that has to be justify from the statistics on all the computation, and strictly speaking this is rather unplausible. Instead of the UD, take the simpler case of the iterated WM self- duplication. Let us fix the iteration to 1000. In this case, you can see easily that what you can expect is not computable at all. All 2^1000 histories will be generated, and the computable are rare. The UD makes dummy similar iteration with all states, so you can guess that physics arise from a subtle mixture of computability and randomness. I think that Bennett depth plays also a role, the self- referential constraints play a role. But it predicts that some randomness is at play in the stabilization/normalisation of the deep computational histories. You don't need step 8 to understand this. Just imagine the physical universe big enough to run a UD. In one instant your futures is determined by an infinity of computations. This shows already that physicists use implicitly an induction principle, by assuming the inexistence of other instantiations of couple you, the observed electron other that the one under their consideration. But the UD guarantied (unlike Boltzmann brain) an infinity of them.

Read the papers, and ask question. Here you just witness your prejudices, and your absence of study.

They have an active role. EM are Turing emulable. You just make the level lower. So, unless you make precise that you believe in - a non Turing emulable component in the EM - different from the what is already make non Turing emulable by comp, you are just begging the question.

This does not entail that it is any more negligible in artificial cognition than flight physics was to artificial flying. This new reality does not mean that an AGI cannot be computational! What it means is that you will never prove what can be replaced by computation without artificially building the physics of cognition and then seeing what can be computed without eliminating/degrading the cognition. Your use of the term physics is like the use of God in gap explanation. A theory of combustion resulted from playing with combustion. Not the other way around.
