I do think thereâs hope for some quantitative estimates even in the speculative cases; for example Open Phil has mentioned that they are investigating the âvalue of the last dollarâ to serve as a benchmark against which to compare current spending (though to my knowledge they havenât said how theyâre investigating it).
Ajeya explains it in her 80k interview and the result is:
âthis estimate is roughly $200 trillion per world saved, in expectation. So, itâs actually like billions of dollars for some small fraction of the world saved, and dividing that out gets you to $200 trillion per world saved. This is quite good in the scheme of things, because itâs like less than two yearsâ worth of gross world product. Itâs like everyone in the world working together on this one problem for like 18 months, to save the world.â
