A couple tried for 18 years to get pregnant. AI made it happen | CNN After trying to conceive for 18 years, one couple is now pregnant with their first child thanks to the power of artificial intelligence.

Great example of where AI gets all the credit but the ACTUAL contribution (in this case, sperm for fertilisation) was from the human. AI helped. It helped a lot. But without the human, AI would be impotent. Good allegory here.

The politics of pronatalism and the two-child benefit cap - British Politics and Policy at LSE Nigel Farage supports the scraping the two-child benefit cap as a way of encouraging people to have more children. But pronatalist policies that offer a one-off "baby bonus" are not effective.

Another excellent piece from a demographer, this time Stuart Gietel-Basten, on how "pronatalism is a dead end"

"Without addressing the root causes of low fertilityโ€”inequality, instability, and the incompatibility of work and family lifeโ€”top-down efforts to โ€œencourageโ€ childbearing will fail"
