Thanks! Presumably both are relevant, or are you suggesting if we were at existential risk levels 50 orders of magnitude below today and it was still as cost-effective as it is today to reduce existential risk by 0.1% you’d still do it?
I meant risk reduction in the absolute sense, where reducing it from 50% to 49.9% or from 0.1% to 0% is a reduction of 0.1%. If x-risk was astronomically smaller, reducing it in absolute terms would presumably be much more expensive (and if not, it would only be able to absorb a tiny amount of money before risk hit zero).
I’m not sure I follow the rationale of using absolute risk reduction here, if you drop existential risk from 50% to 49.9% for 1 trillion dollars that’s less cost effective than if you drop existential risk from 1% to 0.997% at 1 trillion dollars, even though one is a 0.1% absolute reduction, and the other is a 0.002% absolute reduction. So if you’re happy to do a 50% to 49.9% reduction at 1 trillion dollars, would you not be similarly happy to go from 1% to 0.997% for 1 trillion dollars? (If yes, what about 1e-50 to 9.97e-51?)
Thanks!
