Were capable of and bothered to, I suppose. I rarely bother to explain the reasons for my value judgments unless I'm specifically asked, and sometimes not even then. Especially not when it comes to value judgments of random people on the Internet. Low-value Internet interactions are fungible.

See edit on this post . Also, note that this tirade starts from going down to -6 votes (or so) on, you know, perfectly valid issue that Solomonoff induction has with expressing the MWI. You get the timeline backwards. I post something sensible, concise and clear, then I get it down -6 or so, THEN I can't help it but assume utter lack of understanding. Can't you see I have my retaliate button too? There's more downvotes here to pointing out a technical issue normally without flaming anyone. This was early in my posting history (before me disagreeing with anyone massively thats it):

http://lesswrong.com/lw/ai9/how_do_you_notice_when_youre_rationalizing/5y3w

and it is me honestly expressing another angle on the 'rationalization', and it was at -7 at it's lowest! I interpret it as '7 people disagree'.

edit: also by someone I tend to refer to 'unknown persons', i.e. downvoters of such posts.

p.s. please note that the field is VERY full of impossibility proofs (derived from Halting Problem) which are of the form 'this does not resolve" (and full of "even if you postulate that this resolves, then something else doesn't resolve") and I do not look very hard indeed into the possibility that the associated subtleties resolve. Please also note that the subtlety of 'the output must begin with data' is not the kind of subtlety that resolves in any way. I can sometimes be very certain that a subtlety does not resolve; most of the time I am not certain (this field is outside my field of expertise) and I seldom if ever comment on those points (e.g. I refrained from commenting on Solomonoff induction here in the beginning of my post history) and I do not comment negatively on those.

The Solomonoff induction is a very complicated topic and it requires very careful consideration before the speculations. Due to it's high difficulty the probability of subtleties resolving is considerably less than in the less complicated topics.

private_messaging is a troll

Wikipedia:

a troll is someone who posts inflammatory extraneous, or off-topic messages in an online community, such as an online discussion forum, chat room, or blog, with the primary intent of provoking readers into an emotional response or of otherwise disrupting normal on-topic discussion

Let's see:

• inflammatory: check
• extraneous: sometimes, not in this case
• off-topic: not exactly
• intent to provoke/disrupt: not in my estimation

so, maybe 25-30% trollness.

Safely assume bad faith.

I never get this impression from his posts. They seem honest (if sometimes misguided) not malicious to me.

Hmm so you safely assume that I made up a requirement that the observed data be at the start of the string that is output?

I suspect that others downvote private_messaging because of his notoriety. I did downvote his comment because he strayed away from my explicit (estimate the complexity of the Newton's 2nd law) request and toward a flogged-to-death topic of MWI vs the world. Such a discussion has proven to be unproductive time and again in this forum.

Likewise. (With the caveat that I endorse downvoting extreme cases based on notoriety so probably would have downvoted anyway.)

If F, m and a are true real numbers, its un-computable (can't code it in TM) and not even considered by Solomonoff induction, so here.

That's a cop-out, just discretize the relevant variables to deal with integers, Planck units, if you feel like it. The complexity should not depend on the step size.

In that case, Ci is MWI, so why draw the distinction?
