"Magical gods" in the conventional supernatural sense generally don't exist in any universes, insofar as a lot of the properties conventionally ascribed to them are logically impossible or ill-defined, but entities we'd recognize as gods of various sorts do in fact exist in a wide variety of mathematically-describable universes. Whether all mathematically-describable universes have the same ontological status as this one is an open question, to the extent that that question makes sense.

(Some would disagree with referring to any such beings as "gods", e.g. Damien Broderick who said "Gods are ontologically distinct from creatures, or they're not worth the paper they're written on", but this is a semantic argument and I'm not sure how important it is. As long as we're clear that it's probably possible to coherently describe a wide variety of godlike beings but that none of them will have properties like omniscience, omnipotence, etc. in the strongest forms theologians have come up with.)

I (or someone) should update that page; the earliest source of the horseshoe story that I know of is from a 1927 essay by Heisenberg:

Niels closed the conversation with one of those stories he liked to tell on such occasions: "One of our neighbors in Tisvilde once fixed a horseshoe over the door to his house. When a mutual acquaintance asked him, 'But are you really superstitious? Do you honestly believe that this horseshoe will bring you luck?' he replied, 'Of course not; but they say it helps even if you don't believe it.'"

Edit: Actually that date is almost definitely wrong, the essay refers to a conference that took place in 1927, probably wasn't given there. The earliest Google Books result for this quote is Heisenberg's 1969 autobiography, though, so that's still earlier and more authoritative than any of the sources given on the Wikiquote page.

Indeed

Note also that I have a general policy of keeping anything related to religion out of the rationality book - that there be no mention of it whatsoever.

I regularly let tabs proliferate until I have a dozen windows open and hundreds of tabs between them and the browser gets so slow that I have to restart it or it just crashes. When this happens, I usually don't feel like waiting for hundreds of tabs to reload, so I move the saved browser session aside, telling myself I'm just making a "temporary" new session, and then the same thing happens and I never revisit any of my past sessions. I have browser session files dating back to… 2007? That can't be right, this has been going on for way longer than that… maybe I have the older ones on a backup somewhere.

Anyway, I think I have a problem.

I can only assume he wasn't actually talking about an AGI-level breakthrough. I don't think I'd expect him to underestimate the impact or value of AGI that severely.

I assumed that was more based on cultural norms than LW norms. Generally people don't discuss their IQs in polite company (or potentially-high-variance-IQ company, maybe), especially high IQs, because of the risk of being seen as bragging about something that other people may not view as high-status. In discussions outside LW I've heard people be somewhat condescending toward people who even admit to having gotten their IQs tested, as it's often associated with intellectual pretension. (And, in turn, being seen as claiming high status in a way that actually marks one as low-status is associated with social unawareness.)

One (currently slightly downvoted) comment doesn't seem like much of an indicator of a growing community social norm. Does anything else give you that impression?

This could also be fixed by splitting the question into "gender (male/female/other)" and "Are you trans? (yes/no)", but then you'd get other complaints.

I was going to raise exactly that issue and suggest that solution. What complaints would you expect, though? I don't know if I'd really expect any non-trans LWers to be insulted at the mere suggestion that the question is worth asking.

Also, for the record: I'm not "considering cryonics". I'm cryocrastinating. Cryonics is obviously the best choice, and I should be signing up for it in the next five seconds.

I'd have liked having that option too.
