I responded privately earlier... I really don't quite know why I still bother posting here. Also btw, there's other thing: I posted several things that werequite seriously wrong, in the sense of wrong chain of reasoning (not outcome). Those were upvoted and agreed with a fair lot.

Also, on the MWI, I am a believer that as far as we know there can be many worlds out there, and even if quantum mechanics is wrong it is fairly natural for mathematics to work out to many worlds, and it is not like believing in the apple cake in the asteroid belt. I do not dislike the conclusion. I dislike the argument. Ditto for Solomonoff induction and theism, I am an atheist. I tend to be particularly negative towards the arguments that incorrectly argue in favour of what I believe, on the few times that I notice the incorrectness (obviously that got to be much less common than seeing incorrectness in the arguments in favour of what I don't believe).

Well, taking for granted some particular class of bits is very problematic when you have brute force search over values of those bits. You can have a reasonably short program (that can be shorter than physics) which would iterate all theories of physics and run them for a very very long time. Then if you are allowed to just search for the observers, this program will be the simplest theory, and you are effectively back to the square one; you don't get anything useful (you got solomonoff induction inside solomonoff induction). Sorry I still can't make sense out of it.

I also don't see why I should have searched for possible resolutions, and assume that other party has good reason to expect such resolution, if I reasonably believe that such resolution would have a good chance at Fields medal (or even a good reason to expect such resolution would).

I also don't like speculative conjectures via lack of counter argument as combined with posts like this (and all posts inspired by it's style), and feel very disinclined to run the highly computationally expensive search for possible solutions by a person that would not have such considerations about the entire majority of scientists that he thinks believe in something other than MWI. (in so much as MWI is part of CI every CI endorser believes in MWI in a way, they just believe that it is invalid to believe in extra worlds that can't be observed, or other philosophical stance that is a matter of opinion).

edit: that is to say, the stance often expressed on MWI here is normative: if you don't believe in MWI you are wrong, and not just that, but the scientific community is wrong for not believing in MWI. That is the backgrounder. I do believe many worlds are a possibility, but I do not believe the above argument to be valid. And as you yourself have eloquently explained, one should not proclaim those believing in MWI to be stupid on basis of unresolved problems not being resolved (I do not do that). But this also goes with CI, and I am not the community that is being normative about what is rational and judges by MWI belief status whenever one's rational. edit2: and I do not see how this strong-pro-MWI stance is compatible with awareness of the subtleties. Furthermore, at the point when you make so many implicit assumptions about subtleties resolving in your favour, you could as well say Occam's razor; it is not appropriate to use specific term (Solomonoff induction) to refer to something fuzzy.

Intent makes a difference for me. private_messaging seems to want to get his point across (not counting an occasional rant), without regard to the way his comments come across. I did not detect any intent of riling people up for its own sake.
