If we run any more anonymous surveys, we should encourage people to pause and consider whether they are contributing productively or just venting. I'd still be in favour of sharing all the responses, but I have enough faith in my fellow EAs to believe that some would take this to heart.
One of the vague ideas spinning around in my head is that maybe in addition to EA which is a fairly open, loosely co-ordinated, big-tent movement with several different cause areas, there would also in value in a more selective, tightly co-ordinated, narrow movement focusing just on the long term future. Interestingly, this would be an accurate description of some EA orgs, with the key difference being that these orgs tend to rely on paid staff rather than volunteers. I don't have a solid idea of how this would work, but just thought I'd put this out there...
Oh, I would've sworn that was already the case (with the understanding that, as you say, there is less volunteering involved, because with the "inner" movement being smaller, more selective, and with tighter/more personal relationships, there is much less friction in the movement of money, either in the form of employment contracts or grants).
I suspect that it could be impactful to study say a masters of AI or computer science even if you don't really need it. University provides one of the best opportunities to meet and deeply connect with people in a particular field and I'd be surprised if you couldn't persuade at least a couple of people of the importance of AI safety without really trying. On the other hand, if you went in with the intention of networking as much as possible, I think you could have much more success.
