[1. Do you think many major insights from longtermist macrostrategy or global priorities research have been found since 2015?]
I think "major insights" is potentially a somewhat loaded framing; it seems to imply that only highly conceptual considerations that change our minds about previously-accepted big picture claims count as significant progress. I think very early on, EA produced a number of somewhat arguments and considerations which felt like "major insights" in that they caused major swings in the consensus of what cause areas to prioritize at a very high level; I think that probably reflected that the question was relatively new and there was low-hanging fruit. I think we shouldn't expect future progress to take the form of "major insights" that wildly swing views about a basic, high-level question as much (although I still think that's possible).
[2. If so, what would you say are some of the main ones?]
Since 2015, I think we've seen good analysis and discussion of AI timelines and takeoff speeds, discussion of specific AI risks that go beyond the classic scenario presented in Superintellilgence, better characterization of multipolar and distributed AI scenarios, some interesting and more quantitative debates on giving now vs giving later and "hinge of history" vs "patient" long-termism, etc. None of these have provided definitive / authoritative answers, but they all feel useful to me as someone trying to prioritize where Open Phil dollars should go.
[3. Do you think the progress has been at a good pace (however you want to interpret that)?]
I'm not sure how to answer this; I think taking into account the expected low-hanging fruit effect, and the relatively low investment in this research, progress has probably been pretty good, but I'm very uncertain about the degree of progress I "should have expected" on priors.
[4. Do you think that this pushes for or against allocating more resources (labour, money, etc.) towards that type of work?]
I think ideally the world as a whole would be investing much more in this type of work than it is now. A lot of the bottleneck to this is that the work is not very well-scoped or broken into tractable sub-problems, which makes it hard for a large number of people to be quickly on-boarded to it.
[5. Do you think that this suggests we should change how we do this work, or emphasise some types of it more?]
Related to the above, I'd love for the work to become better-scoped over time -- this is one thing we prioritize highly at Open Phil.
I liked this answer.
One thing I'd add: My guess is that part of why Max asked about novel insights is that he's wondering what the marginal value of longtermist macrostrategy or global priorities research has been since 2015, as one input into predictions about the marginal value of more such research. Or at least, that's a big part of why I find this question interesting.
So another interesting question is what is required for us to have "many smaller insights" and "the refinement and diffusion of ideas that aren’t strictly speaking novel"? E.g., does that require orgs like FHI and CLR? Or could we do that without paid full-time researchers, just via a bunch of people blogging in their spare time?
I don't know about generating many smaller insights or refining ideas. But I'd guess that mere "diffusion" probably doesn't require full-time researchers, just good and well-respected communicators.
But I'd also guess that there's another thing that happened: Active critique and screening of a large set of potentially important insights, to identify those that are actually important and correct (or sufficiently likely to be correct to warrant major shifts in decisions). And that process seems likely to benefit substantially from having orgs like FHI and CLR. Both because the set of potentially important insights might be very large, and because effectively screening them might be something most people can't easily do.
And I'd guess that ideas tend to diffuse more and more as they do better in the screening process.
But I only got involved in EA in 2018, and only got inside peaks into some EA orgs this year, so a lot of the above is guesswork.
