Ok, go to like, every other city in China, Japan, South Korea, or most of the cities of Western Europe. Take your pick.

All civilizations in decline because they can’t accommodate the basic human function of conveniently raising 2.1 new humans per couple. What’s the point of technology that doesn’t serve human needs?

Go to Dallas and look at all the families with 3-4 kids. That’s what the future looks like. (Except the minivans and pickup trucks are probably electric.)

Texas is 1.8-1.9 child per family, the same as California. If you want to see four kid families, you need to go to SLC, not Dallas.

California is a big place. Just 13% of San Francisco’s population is under 18; and Hong Kong is about the same. Garland and Bakersfield are double that. Public transit apparently kills a civilization’s desire to perpetuate itself.

We're moving to a future where fewer humans are necessary to run economies. The trend of the future is smaller and more prosperous populations doing more meaningful activities, rather than a future of slum-ponzi-ism where an ever increasing amount of bodies are needed to fuel economic growth.

In this context we’re talking about merely being able to maintain population stability.
