I'm inclined to think that Eliezer's clear confidence in his own very high intelligence and his apparent high estimation of his expected importance (not the dictionary-definition "expected", but rather, measured as an expected quantity the usual way) are not actually unwarranted, and only violate the social taboo against admitting to thinking highly of one's own intelligence and potential impact on the world, but I hope he does take away from this a greater sense of the importance of a "the customer is always right" attitude in managing his image as a public-ish figure. Obviously the customer is not always right, but sometimes you have to act like they are if you want to get/keep them as your customer... justified or not, there seems to be something about this whole endeavour (including but not limited to Eliezer's writings) that makes people think !!!CRAZY!!! and !!!DOOMSDAY CULT!!!, and even if is really they who are the crazy ones, they are nevertheless the people who populate this crazy world we're trying to fix, and the solution can't always just be "read the sequences until you're rational enough to see why this makes sense".

I realize it's a balance; maybe this tone is good for attracting people who are already rational enough to see why this isn't crazy and why this tone has no bearing on the validity of the underlying arguments, like Eliezer's example of lecturing on rationality in a clown suit. Maybe the people who have a problem with it or are scared off by it are not the sort of people who would be willing or able to help much anyway. Maybe if someone is overly wary of associating with a low-status yet extremely important project, they do not really intuitively grasp its importance or have a strong enough inclination toward real altruism anyway. But reputation will still probably count for a lot toward what SIAI will eventually be able to accomplish. Maybe at the point of hearing and evaluating the arguments, seeming weird or high-self-regard-taboo-violating on the surface level will only screen off people who would not have made important contributions anyway, but it does affect who will get far enough to hear the arguments in the first place. In a world full of physics and math and AI cranks promising imminent world-changing discoveries, reasonably smart people do tend to build up intuitive nonsense-detectors, build up an automatic sense of who's not even worth listening to or engaging with; if we want more IQ 150+ people to get involved in existential risk reduction, then perhaps SIAI needs to make a greater point of seeming non-weird long enough for smart outsiders to switch from "save time by evaluating surface weirdness" mode to "take seriously and evaluate arguments directly" mode.

(Meanwhile, I'm glad Eliezer says "I have a policy of keeping my thoughts on Friendly AI to the object level, and not worrying about how important or unimportant that makes me", and I hope he takes that seriously. But unfortunately, it seems that any piece of writing with the implication "This project is very important, and this guy happens, through no fault of his own, to be one of very few people in the world working on it" will always be read by some people as "This guy thinks he's one of the most important people in the world". That's probably something that can't be changed without downplaying the importance of the project, and downplaying the importance of FAI probably increases existential risk enough that the PR hit of sounding overly self-important to probable non-contributors may be well worth it in the end.)
