But those aren’t intractable issues and society will adapt. I think that’s key critique - extrapolation is a problem when you have feedback systems to adjust to changing environmental conditions. Like even if no one has kids for 10 years, we still have new ones being born. If it’s super critical to society you’ll see all sorts of programs and support spring up to encourage people to have larger than today normal families (eg offering free childcare etc). Also, you seem to have dismissed geriatric pregnancies out of hand (not to mention limiting counting pregnancies to specific subgroups for some reason because you view other types of kids as undesirable?) but I don’t see why that’s the case - children born during this time are still children. Fertility levels may be reduced but they still happen.

The point is that the claim that we’ll have a species-wide population collapse seems unreal when we have more people on earth than ever and we have lots of children at every age group giving us lots of shots to adjusts to problems. Not to mention tech that extends the fertility age well beyond the limited window you’ve said.

There’s a lot of baked in stereotyping it seems like on your end of what “acceptable” children look like that may be worth unpacking more than there being any serious concern about a population collapse.
