Your goals could be something like improving personal relationships, allowing a better legal system to take over, or generating funding or talent for SIAI, which would require increasingly good rationalists.

If I had to guess, I'd guess that you're going for the 'other' category because it includes all sorts of important things which add up/may dominate, and figure that top 0.1%-0.01% is about right.

That doesn't sound like a bad answer at all, and I'm not sure how I'd change it. I'm just emphasizing the point that the choice matters a lot, and that extra thinking helps.

It's the kind of thing I'd want to have a discussion about at the next LW meetup, and by the time I start actively teaching people I'd want to have thought about it enough that I can't bring someone up to speed with my full reasoning in a minute or two.
