Wow, this is long, and seems pretty detailed and interesting. I'd love to see someone write a selection of key quotes or a summary.
There is now also an interview with Critch here: https://futureoflife.org/2020/09/15/andrew-critch-on-ai-research-considerations-for-human-existential-safety/
Andrew Critch's (Academian) and David Krueger's review of 29 AI (existential) safety research directions, each with an illustrative analogy, examples of current work and potential synergies between research directions, and discussion of ways the research approach might lower (or raise) existential risk.
