I'm not talking about endless growth. I'm talking about simply maintaining existing societies. The fertility rate in South Korea is now below 1. That's a society that's basically gone within three generations.

Right--so what does society and culture look like then?

We can't even fix male pattern baldness for god's sake.
Culture and societies change. No one can predict the future. If the population of South Korea goes down to 49 million (from 50 million today), why does that automatically mean that they will lose their culture?
>We can't even fix male pattern baldness for god's sake.
I'm sure we will fix that before the population gets to zero!
Elon Musk used to be bald. Now he’s not.
Who will raise the people who were made in vats? Which is the real problem here, not who reproduces.
I would say it depends. My wife would not want to miss it. Especially her first birth was indeed a wonderful experience. The second was too fast but still a wonderful experience.
Why children per woman? In such a world where humans grow in vats, it would be children per person...
I think we are going to have to adapt to a post-growth world. Or maybe things will grow in other ways. I am not worried about declining birth rates. It's not like we are heading for a "Children of Men" scenario. The population will stabilize before it goes to zero. Or maybe we will just grow people in vats.
