Well that's the point about unknown unknowns though, we actually have no idea what the probability is. But we do know it's not low, that's the only unlikely scenario.

We only know it's a very complicated system with many interlocking dependencies, and based on what we know about complicated systems in general, as well as biology in particular, is that if any one of these unknown dependencies break, the whole system can fail catastrophically.

Therefore the probability that something will go wrong is very high, and the damage could easily be irreparable damage to the species, if not extinction. Does that not give an intolerably high risk?

I don’t think this technology we’ll get people to stop having sex to the degree that IVG is all we’ll ever use. And to the degree that we believe some humans are genetically destined for anything, that’s the line of thinking that leads to dystopia.

I 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.

Unfortunately most of society and the economy is built on the foundational assumption of a growing (or at least stable) population. There will be some extremely tough challenges to solve with an actively declining population.

A lot of these issues have more to do with how we’ve constructed our society than with some loss of purity. If you want people to have more sex, make cities and towns more livable, get people out of cars, give them living wages so they have free time, create societal supports for childcare, make giving birth and pediatric care completely free, and support people forming associations outside of work. These are all barriers that have appeared basically my lifetime and it’s way more likely that people are making informed choices than that there’s some horrible transformation we’re all undergoing.
