Because I don’t care about “humanity in general” nearly as much as I care about my society. Yes, sure, the descendants of the Amish and the Taliban will cover the earth. That’s not a future I strive for. I’d be willing to give up large chunks of the planet to an ASI to prevent that.
I don’t know how you would prevent that. Absent an AI catastrophe, fertility will recover, in the sense that “we” (rationalists etc) will mostly be replaced with people of low IQ and impulse control, exactly those populations that have the highest fertility now. And “banishing aging and death” would not prevent them from having high fertility and dominating the future. Moloch is relentless. The problem is more serious than you think.
