alt Hacker NewsI don't know man, people basically aren't having sex already. The fertility rate is way below replacement in all modernized countries, half of gen Z has never had sex at all, contraception is free, people struggle to get pregnant the more chronically ill the population gets, and the people who actively do want to get pregnant are going to want to use whatever technology there is to improve things.
But outside the bible, who says we must be more and above replacement rates? Is such a tragedy for humanity if there are only 4 billion humans in 100 years? 4 happier billions? It doesn't HAVE to go up all the time, and between extinction (zero humans) and overcrowding (X billions) there are many unknown ways to go.
