Multiple scholars have argued based on the size of the "cosmic endowment" that because of the inconceivably large number of potential future lives that are at stake, even small reductions of existential risk have great value. Species that survived the dinosaur-killing asteroid rarely relied on a single food source. So we’re vulnerable, but there are reasons to think humans are resistant to extinction, maybe uniquely so.
