At that point, our population would halve in about one human lifespan.
Holy fuck can our greenhouse gasses and energy use drop proportionately? 'cuz that would be AMAZEBALLS
I'm not sure how people manage to be freaked out by the coming joblessness due to automation, the coming inequality due to resource depletion, and the coming population crash all at once. Not to put too fine a point on it but if COVID were to wipe out half the population in the world, our energy and water use per person could double without any problems. Probably not the hot take Ryan Cooper was looking for but uhhh there are a whole lot of problems solved through population reduction and "aging out" is far and away the best way to accomplish it.
