[EDIT: Thanks for the questions everyone! Just noting that I'm mostly done answering questions, and there were a few that came in Tuesday night or later that I probably won't get to.]
Hi everyone! I’m Ajeya, and I’ll be doing an Ask Me Anything here. I’ll plan to start answering questions Monday Feb 1 at 10 AM Pacific. I will be blocking off much of Monday and Tuesday for question-answering, and may continue to answer a few more questions through the week if there are ones left, though I might not get to everything.
About me: I’m a Senior Research Analyst at Open Philanthropy, where I focus on cause prioritization and AI. 80,000 Hours released a podcast episode with me last week discussing some of my work, and last September I put out a draft report on AI timelines which is discussed in the podcast. Currently, I’m trying to think about AI threat models and how much x-risk reduction we could expect the “last long-termist dollar” to buy. I joined Open Phil in the summer of 2016, and before that I was a student at UC Berkeley, where I studied computer science, co-ran the Effective Altruists of Berkeley student group, and taught a student-run course on EA.
I’m most excited about answering questions related to AI timelines, AI risk more broadly, and cause prioritization, but feel free to ask me anything!
One issue I feel the EA community has badly neglected is the probability given various (including modest) civilizational backslide scenarios of us still being able to (and *actually*) developing the economies of scale needed to become an interstellar species.
To give a single example, a runaway Kessler effect could make putting anything in orbit basically impossible unless governments overcome the global tragedy of the commons and mount an extremely expensive mission to remove enough debris to regain effective orbital access - in a world where we've lost satellite technology and everything that depends on it.
EA so far seem to have treated 'humanity doesn't go extinct' in scenarios like this as equivalent to 'humanity reaches its interstellar potential', which seems very dangerous to me - intuitively, it feels like there's at least a 1% chance that we wouldn't ever solve such a problem in practice, even if civilisation lasted for millennia afterwards. If so, then we should be treating it as (at least) 1/100th of an existential catastrophe - and a couple of orders of magnitude doesn't seem like that big a deal especially if there are many more such scenarios than there are extinction-causing ones.
Do you have any thoughts on how to model this question in a generalisable way that it could give a heuristic for non-literal-extinction GCRs? Or do you think one would need to research specific GCRs to answer it for each of them?
