Hmm, should I be more worried and outraged about genocides that are happening at this very moment, or some imaginary scifi scenario dreamed up by people who really like drawing charts?
One of the ways the rationalists try to rebut this is through the idiotic dust specks argument. Deep down, they want to smuggle in the argument that their fanciful scenarios are actually far more important than real life issues, because what if their scenarios are just so bad that their weight overcomes the low probability that they occur?
(I don't know much philosophy, so I am curious about philosophical counterarguments to this. Mathematically, I can say that the more they add scifi nonsense to their scenarios, the more that reduces the probability that they occur.)
