I like how you're characterizing this!
I get that the diagram is just an illustration, and isn't meant to be to scale, but the EA portion of the GHD bubble should probably be much, much smaller than is portrayed here (maybe 1%, because the GHD bubble is so much bigger than the diagram suggests). This is a really crude estimate, but EA spent $400 million on GHD in 2021, whereas IHME says that nearly $70 billion was spent on "development assistance for health" in 2021, so EA funding constitutes a tiny portion of all GHD funding.
I think this matters because GHD EAs have lots and lots of other organizations/spaces/opportunities outside of EA that they can gravitate to if EA starts to feel like it's becoming dominated by AI safety. I worry about this because I've talked to GHD EAs at EAGs, and sometimes the vibe is a bit "we're not sure this place is really for us anymore" (especially among non-biosecurity people). So I think it's worth considering: if the EA community further grows the AI safety field, is this liable to push non-AI safety people—especially GHD people, who have a lot of other places to go—out of EA? And if so, how big of a problem is that?
I assume it would be possible to analyze some data on this, for instance: are GHD EAs attending fewer EAGs? Do EAs who express interest in GHD have worse experiences at EAGs, or are they less likely to return? Has this changed over time? But I'd also be interested in hearing from others, especially GHD people, on whether the fact that there are lots of non-EA opportunities around makes them more likely to move away from EA if EA becomes increasingly focused on AI safety.
Thanks for this and great diagrams! To think about what the relationship between EA and AI safety, it might help about what EA is for in general. I see a/the purpose of EA is helping people figure out how they can do the most good - to learn about the different paths, the options, and the landscape. In that sense, EA is a bit like a university, or a market, or maybe even just a signpost: once you've learnt what you needed, or found what you want and where to go, you don't necessarily stick around: maybe you need to 'go out' in the world to do what calls you.
This explains your venn diagram: GHD and animal welfare are causes that exist prior to, and independent of EA. They, rather than EA, are where the action is if you prioritise those things. AI safety grew up inside EA.
I imagine AI safety will naturally form it own ecosytem independent of EA: much like, if you care about global development, you don't need to participate in the EA community, a time will come when, for AI safety, you won't need to participate in EA either.
This doesn't mean that EA becomes irrelevant, much like a university doesn't stop mattering when students graduate - or a market ceases to be useful when some people find what they want. There will be further cohorts who want to learn - and some people have to stick around to think about and highlight their options.
