The predisposition may be cultural rather than genetic.
Religious people belonging to certain religions/sects do have a lot more children even in the contemporary world. Maybe the world of 2100 is going to be a lot more religious than today.
The development is certainly visible in, say, Israel, or even migrant communities in Europe. Europeans must now be a bit careful not to insult Islam; that wouldn't be the case fifty years ago.

I can imagine some other developments. Maybe parenting will become professionalized, kids will be born in artificial wombs and specialized pairs will take care of 10 of them at once.
It sounds wild, but we already professionalized a lot of other activities that were "naturally" done by households, such as fuel gathering, cooking, home construction and small agriculture.
I'm aware of that. That's why I questioned the validity of the idea, because it seems too risky to rely on. Probably unsustainable because the ever faster changes of the 'meteorological machine' will disrupt many other mechanisms, because they are too slow to adapt.
The idea of mechanizing/automating/centralizing that stuff is irking me in general. One could argue that the biologisms which evolved us, and we with and through them, are just another, rather imperfect way of doing this, by slow, biologic means.
IMO this only leads to transhumanism, which I consider BS, because it will produce shadows/weak simulations of the real thing and philosophical zombies.
