> Over many generations we may be able to lower our birthrate to compensate
We’ve gone—globally—from 5.3 births per woman in 1963 to 2.3 in 2022 [1]. 2.1 is replacement [2]. In the rich world, where longevity treatments will first become available, it’s 1.6 [3]. (3.3 in 1960.)
There are arguments against longer lifespans. Population growth is not one of them.
