What is your take on the prospect of AI assisting human fertility rather than replacing it? If AI robots are becoming more useful in the everyday household - as they are in assisting the elderly - could it save people enough "time and energy" needed to turn the obligation of childrearing into an attractive thing?
The barriers to increased fertility in East Asian countries are likely a lack of time, long work hours, the advent of personalized entertainment (movies, TikTok/Douyin, etc.), generational expectations of an one-child family, and the massive cost of childrearing. At least a couple of these factors concerning time & effort could be alleviated by the introduction of helper "robots" within the home.
Not wanting to have children early is a mentality thing - people want to travel, work overseas, do various things or work on things that raising a child would interfere with. A person's mentality changes when they have children and that is something I believe a lot of young people are putting off because they still haven't ticked off all the things on their list.
It would be wrong and impractical to try to divert people's mentalities away from this lifestyle focused behavior, because it comes hand in hand with economic prosperity.
The majority of these people end up having children, but just later in life, where the risk of failed pregnancies and other issues are higher.
I believe the three most important things are:
1 - Ideological / Cultural: Instilling the idea that "family = happiness" in children's minds at a very early age, as they will eventually act on it when they are ready. The ultimate meaning in life is to bring a new generation to the world and further our great civilization, the greatest happiness is watching your grandchildren grow, and the greatest duty to your parents is to give them grandchildren.
2 - Health based: Decreasing the risks and issues with having children later in life (e.g. late 30's to 40's), as I believe this is a big part of why some couples decide to not have children anymore - they are 'too old' and the risks to the health of the mother and baby are too great.
3 - Cost: Free / low cost collectivized childcare - I have some reservations about robot nannies, as they may cause unwanted effects to the socialization and development of a child (e.g. suspicious towards adults because they spent more time with and being cared for by a robot); collectivized free / low cost childcare where children interact with other children and adults may be the way to go as a more sustainable route.
