I respect that opinion, I'm just interested in theories which are instrumental in solving this universe's problems. You know, trivial stuff: wars, famines and death. A TOE which says: universe is information, every possible pattern exists, observers which can observe themselves will, is a bit sterile in that respect. There's a little problem with some practical relevance I don't have an answer, though, which I'd like to have your opinion on. We have a finite system, iteratively evolving along a trajectory in state space. We have observers within that system, subjectively experiencing a flow of time. I have trouble alternating between the internal and the external observer view. So we have a machine crunching bits, sequentially falling from state to state. This spans a continous trajectory. We can make a full record of that trajectory, eliminating a time axis. When does the subjective observation of existence assemble into place? The first time the computation was made? I have trouble seeing my subjective observer experience as a sequence of frames, already computed. Is the first run magical, and the static record dead meat? I'm confused. Let's bring a little dust into the run. Let's say we use a HashLife approach, which assembles the flow from lightcone hashes. Does this screw up the subjective experience? If yes, how? What about computing a record of all possible trajectories? Is enumerating all possible states sufficient to create an observer experience? I haven't spent much time on this, so maybe you can bring some light into the matter. > That's all my thesis > is about.
