it's ludicrous how few people know about this paper, so, friendly reminder that the fermi paradox was completely resolved in 2018 and it turned out to be because multiplying point estimates of highly uncertain parameters is very bad actually

just an embarrassing chapter in the intellectual history of humanity tbh. decades of ink spilled over what amounts to a failure to understand that the product of a bunch of independent random variables is ~lognormal (ish) and a highly uncertain lognormal has a very heavy tail

my favorite point that isn't just "lol git gud at probability" is that the most uncertainty by far in the drake equation is about the rate at which earth-like planets produce life; they argue for uncertainty over 200 orders of magnitude which is where the tail comes from

I always sorta figured the Drake equation was just numbers that were varying degrees of made up.

Cool man. This actually is the best point of the whole thing.
Though, 200 orders seems like a lot and I might personally argue for less. But also... none of this really matters to me.. lol
