Thanks for writing this Peter, i really like the critcisms. I would have loved to see some suggestions on solutions even if they are super early initial ideas.
One thing i did want to comment on in particular was this << I think EA, and especially longtermism, has pretty homogenous demographics in a way that I think reduces our impact>>
I think its a good point but i think a large part of it is due to how unwelcoming EA is to women and how hard it is to be taken seriously as a woman in the EA community. As an example i would be curious to know how many of the posts on the EA forum are written by women vs. men and how many of the top posts are written by women. I could be wrong here maybe its not that different because i havent done the analysis. But anecdotally i know at least 3 women who write their own EA related blogs but wouldnt bother to write on the EA forum, feeling like they would be shot down or not valued.
Secondly without wanting my opinion to be cancelled as being "social justice" I dont think this is just a gender problem, it is also a race issue as argued here: https://forum.effectivealtruism.org/posts/oD3zus6LhbhBj6z2F/red-teaming-contest-demographics-and-power-structures-in-eaI genuinely think this is going to be a limiting factor for EA if it continues in this way and that makes me very sad, more should be done to proactively attract, welcome and retain other genders and race, otherwise this will continue to affect our talent issues.
