I read along in your explanation, and I’m nodding, and saying “yup, okay”, and then get to a sentence that makes me say “wait, what?” And the whole argument depends on this. I’ve tried to understand this before, and this has happened before, with “the universal prior is malign”. Fortunately in this case, I have the person who wrote the sentence here to help me understand.
So, if you don’t mind, please explain “make them maximally probable”. How does something in another timeline or in the future change the probability of an answer by writing the wrong answer 10^100 times?
Side point, which I’m checking in case I didn’t understand the setup: we’re using the prior where the probability of a bit string (before all observations) is proportional to 2^-(length of the shortest program emitting that bit string). Right?
