Surprisingly (for secularists), post religion means degrowth of the culture. So it’s a good thing if you want Europe’s culture replaced by what the data show is happening, and it’s a bad thing if you think Europe’s traditional culture is worth saving.

Well where I am (Edinburgh) we have a superabundance of culture at this time of year - very little of which has anything to do with religion?

I’m alluding to the long term trends(one - two generations out, assuming they follow the behavior of the last two generations).

Humans all across the developed world work 40% fewer hours than in 1900: https://ourworldindata.org/working-more-than-ever . Yet, in the U.S., TFR has consistently been dropping since 1800 : https://ourworldindata.org/working-more-than-ever .

> Working hours for the average worker have decreased dramatically over the last 150 years. note the “average worker”. If women were staying at home with children, they were not counted as workers.

If they were, the averages would just be higher, their jobs are nonstop at home.

Funny, I just wrapped a blog post about this: https://green.spacedino.net/i-dont-worry-about-population-de... Good presentation by the author that reaffirms my own opinions about the topic, specifically that while it sucks and cripples the social welfare programs our (deceased) elders built on the theory of continued population and productivity growth, it's also an issue we can fix with coordination between powers an…

Here is an uncomfortable truth: religious people produce more children, regardless of their income, social welfare status and living conditions. They are thought from birth that marriage, family and children are gifts from "God". In fact, Christians make it a _requirement_ to be "open to life" (i.e have children) before they agree to marry you in Church (in addition to banning contraceptives, abortions and porn). The…

It’s crazy this was downvoted. This is basically a summary of all pew research on this topic - lol.

The last line of the slide reads "Once you start thinking about these issues, it is hard to think about anything else: demography is destiny." Raoul Pal primary thesis about macroeconomics is that Demographics is everything. Here is a 54 second video of him highlighting that issue. https://www.youtube.com/watch?v=vJm_zFbIqPE

GDP = people * productivity

I’m super interested on the economic modeling when every society is shrinking.

In that case, the best index fund will be the one that shrinks the slowest. This will happen about 10 years after the average reader here dies.

The selection effects of this transition will be really fascinating to see after the fact. The species has spent a long time under selection pressure for "having more kids", but is being subjected for the first time to "having more kids while extreme prosperity and modern telecommunications exist" which is a very different thing.

I had an evolutionary bio professor in college say this: "you don't understand evolution until you understand how contraception could lead to overpopulation." Anything placed in the path of reproduction is a barrier to be overcome. If there is anything in the human genome that correlates with a positive desire to choose to have children, we are selecting hard for that right now. We may see a bottleneck this century a…

Japan’s population dropped rapidly before contraception was allowed in due to abortion.

Abortion beats a strong selection pressure.

No matter the gender of the one staying at home, it creates a problematic power imbalance between the two parts of the couple, where one depends on the other and may be left in trouble if ever the couple should find an end.

True, which was solved like 8,000 years ago by religion/culture, saying you have to marry and support the mother of your children. It wasn’t perfect of course. Abuse has always been a problem. Yes, everyone has greater absolute freedom now that we have divorce, and abuse victims are better off, but we have not developed a functioning cultural replacement for the previous cultural arrangement. So, now we have a smalle…

No one removed the idea of marriage until you’re tired of the person. Women simply gained civil rights and the ability to earn money and support themselves.

It was commonly accepted for men to have affairs and mistresses, or otherwise neglect wives. Now that they have negotiating power, fewer deals are made, which is to be expected.

The complaining about fertility rates, mostly done by the chunk of the population hoarding more and more of the wealth, will continue until people's ability to afford rent and children improves.

Rational millennials who will have to work until 75 at current rates may also complain :)

If you have access to the sea and to uranium you can make all the freshwater you need, even recycle your own wastewater nearly infinitely. This is a technological and economic problem, not an overpopulation problem.

> If you have access to the sea and to uranium you can make all the freshwater you need I don't believe that would be true on a large scale because the seaside would quickly become polluted with brine, and then having an infinite supply of uranium wouldn't help you. Desalination only works in the long term if there is an unlimited amount of body water to dilute the brine produced by the process.

No, you just evaporate the brine and then you have a large source of lithium for battery production.

The mid-century Baby Boom occurred after a surge in affordable home keeping technologies (vacuum cleaners, washing machines, refrigerators, etc). I think a rebound in fertility will have to come from technology. Specifically, robots to help with child care and new fertility treatments to allow women to have children later in their lives.

My concern is the intersection of rightwing natalism with Silicon Valley ideology leading to technological “solutions” involving, essentially, test tube babies. Take women out of the picture entirely. I can especially see a dystopian dynamic involving the “we have to compete with China” or “they’re doing it / about to do it in China” narratives.

So the Axlotl tanks from Dune.

No, just use the brine as dirty electrolyte :-)
