[...] I think work that looks like ‘different ways of categorising x-risks’ can provide useful conceptual frames for thinking about mitigation through modularity. Some examples of this I’m aware of:
‘Defence in Depth Against Human Extinction: Prevention, Response, Resilience, and Why They All Matter’ (Cotton-Barratt, Daniel, & Sandberg; 2020)
‘Classifying Global Catastrophic Risks’ (Avin et al., 2018); and
I also note in that collection that “Cotton-Barratt also discusses [the Defence in Depth] model, and rationales for building such models, on the 80,000 Hours podcast.”
I previously made a collection of all such things that I was aware of. It only really has 5 items, the most notable of which you’ve already covered. The other two are:
Causal diagrams of the paths to existential catastrophe—me, 2020
Typology of human extinction risks—Alexey Turchin, ~2015
