Unpopular opinion (and playing devil’s advocate since I have two kids), but is it necessarily a bad thing if people stop wanting to have children and the human race just gradually disappears? There are a lot of other types of potential existential threats on the horizon that might be unsolvable and could entail a significant amount of suffering (e.g. global warming, super viruses, rogue AI)—perhaps it’s better to stop reproducing and just let things end peacefully? I can’t thing of a great argument for forcing societies to continue having children if they no longer wish to do so. Sure, you’ll have some “who will take care of all the elderly in 50 years?” but you could plan a bit for that and the problem would only last for one generation.
