No, but this has nothing to do with what I posted, which refers to simulating a human being. An actor is doing nothing of the kind.
Doesn't it? For an actor, or any person, to pretend to be a subject, requires the actor to simulate the subject.
Dude, Turing equivalence! Anything that measures time in Planck intervals can simulate human history using bloody rocks. If you insist on giving the Angel such abilities, you should think it through! In any case, I explain the mistakes as a lack of data; processing speed be damned, garbage in, garbage out. The Angel seems reliant on its human servants for information about the world; that's an extremely limited bandwidth, relative to its processing speed. What's more, humans were clearly quite alien to it at the start, and you can't simulate what you don't know enough about. So its simulation capabilities in 1140 are quite a different beast from what it can do now, with an extra 500 years of data.
I notice two implicit assumptions:
1) Because it measures time in Planck intervals it can compute on those time scales.
2) It has nothing more important to do with its computing power than simulating future histories, complete with melting eyeballs.
It may be in that one or both of these are incorrect.
Also, just because I haven't let the audience in on everything, doesn't mean that I haven't thought it through. Generally if something weird is going on in my AAR, it is intentional.
