While there have been many previous surveys asking about the chance of existential catastrophe from AI and/or AI timelines, none as far as I'm aware have asked about how the level of AI risk varies based on timelines. But this seems like an extremely important parameter for understanding the nature of AI risk and prioritizing between interventions.

Contribute your forecasts below. I'll write up my forecast rationales in an answer and encourage others to do the same.

My overall chance of existential catastrophe from AI is ~50%.

My split of worlds we succeed is something like:

  1. 10%: Technical alignment ends up not being that hard, i.e. if you do common-sense safety efforts you end up fine.
  2. 20%: We solve alignment mostly through hard technical work, without that much aid from governance/coordination/etc. and likely with a lot of aid from weaker AIs to align stronger AIs.
  3. 20%: We solve alignment through lots of hard technical work but very strongly aided by governance/coordination/etc. to slow down and allow lots of time spent with systems that are useful to study and apply for aiding alignment, but not too scary to cause an existential catastrophe.

Timelines probably don’t matter that much for (1), maybe shorter timelines hurt a little. Longer timelines probably help to some extent for (2) to buy time for technical work, though I’m not sure how much as under certain assumptions longer timelines might mean less time with strong systems. One reason I’d think they matter for (2) is it buys more time for AI safety field-building, but it’s unclear to me how this will play out exactly. I’m unsure about the sign of extending timelines for the promise of (3), given that we could end up in a more hostile regime for coordination if the actors leading the race weren’t at all concerned about alignment. I guess I think it’s slightly positive given that it’s probably associated with more warning shots.

So overall, I think timelines matter a fair bit but not an overwhelming amount. I’d guess they matter most for (2). I’ll now very roughly translate these intuitions into forecasts for the chance of AI-caused existential catastrophes conditional on arrival date of AGI (in parentheses I’ll give a rough forecast for AGI arriving during this time period):

  1. Before 2025: 65% (1%)
  2. Between 2025 and 2030: 60% (8%)
  3. Between 2030 and 2040: 55% (28%)
  4. Between 2040 and 2060: 50% (25%)
  5. After 2060: 45% (38%)

Multiplying out and adding gives me 50.45% overall risk, consistent with my original guess of ~50% total risk.

This seems to imply that you couldn't get misaligned AGI arriving and it not causing an existential catastrophe. Is that correct?

I didn't mean to imply that. I think we very likely need to solve alignment at some point to avoid existential catastrophe (since we need aligned powerful AIs to help us achieve our potential), but I'm not confident that the first misaligned AGI would be enough to cause this level of catastrophe (especially for relatively weak definitions of "AGI").

One of my friends and collaborators did this app which is aimed at predicting the likelihood that we go extinct: https://xriskcalculator.vercel.app/

It might be useful!

What definition of AGI are you using?
