People keep poking at the wrong reasons, but in some societies it is quite dire. South Korea with this year of 1, when 2.1 means 'static', means more than halving the population every 30 years or so.
For a reverse comparison, if you take a penny and double it every day, you end up with > $5M in 30 days. And yet this birthrate issue doesn't take into account plague, war, natural disasters, and potential issues with lack of food(starvation). And the worst of it?
Is that I believe it is 100% environmental.
People think "having children" is a conscious choice. And sure, there is some of that. But at the same time, it is the very point of existence for an organism. Actually producing children (not just performing the sex act) is an evolutionary requirement. It is literally the primary drive of existence. Risky behaviour is ingrained into us, if it enables the possibility of reproduction. The drives and energy we place into everything we do, has a background drive that is sexual in nature. We seek to excel, to impress the opposite sex.
Like it or not (I'm not like that, I decide, not my hormones!), this is effectively an accepted fact of animal psychology. It's a part of who we are, our culture is designed around it, and every aspect of our lives is ruled by it.
Why am I on about this??
Well, my point is that this is a primary drive, interlaced so deeply that it affects every aspect of who we are. Reproduction, the production and raising of offspring is an act we are, naturally, compelled to. Forced to. Need to do.
Unless of course specific chemicals, maybe microplastics or all of the "forever chemicals" in our blood, are blocking that process.
Again, people will chime in with the popular "But it's expensive". No. Just no. Nope! My point above is that this is primal drive. People have had children in the depression, on purpose. Historically people, even with contraceptives, have had children regardless.
If it's about money, why is the birth rate declining in countries with free daycare, universal health care, and immensely strong support for parents post birth? Mandated career protection for mothers, months and months of time off after birth all paid. Immense tax breaks making children almost a profitable enterprise. In fact, in some European countries, it is more affordable to have kids than at any time in human history... and the birth rate still declines. It's just not about money. It just is not.
Why I think this is immensely important, is because we aren't seeing a rate, but an ongoing declining rate. The rate isn't just the lowest in human history, but the rate continues to decline. It's not '1' for South Korea, it's 1 right now, and will be 0.5 eventually.
What happens when no one can have children?
I further ask this, because the entire future of the species is at risk. People get all "who cares about going on", but wars do happen, plagues do happen, and I assure you I'm happy to be here, regardless of what the survivors of the bubonic plague thought at the time. Yet if we see a plague that kills 1/2 the population, where does that leave this equation? And what happens if we see a war that kills mostly those of child bearing age? What then?
My secondary concern in all of this is, we have very specialized roles these days. There was a time where a person could be a "a physicist", yet now there are 1000s of sub-specialties in such fields. And not everyone in the population is capable of expanding science. Of discovering 'new'.
My thoughts here are that we require a certain base number of humans to continue to expand science. If we have 100M humans world wide, I do not believe we'll be capable of expanding our current knowledge base, instead, I think we'll regress. There simply will not be enough people intelligent in a way functional to, say, physics, to expand that field.
So if our population decreases too far, we may not be able to resolve issues with, say, forever chemicals. Or with microplastics. Our capacity to do research and resolve such issues may vanish.
Couple that with a graph that is constantly declining, and a simple 50% death rate in a plague, could mean the extinction of the human race.
So my real concern here is, we aren't swinging the pendulum on purpose. It's happening to us. We're in the middle of an extinction event.
The entire point of having human intelligence is being able to ignore or overthink or delay or prevent any primal urges. We also have urges to kill and rake and destroy but I doubt you’re going “laws are bad because they prevent out primal urges”.
Also appeals to evolution are extremely weak and lazy and unproven.
Urges to kill and rake and destroy? The first, yes. The second, lack of care by some.
Yet the first is aggression often born from, again, reproductive drive. You don't see moose smashing the horns together for fun, they do it to exhibit dominance. All creatures strive to say "I'm the best!", in hundreds of subtle and overt ways. "Success" at any act means "I'm a better mate!".
All of human culture, all of human drive, all of our existence is laced, entwined, and coupled with this drive. You may think your fancy pants brain is the ruler of all, but it's not, for the very way you think, is predicated by an enormous amount of physiological drives, the primary being "reproduce".
Saying that "citing concepts from entire branch of science" is weak, is a very weird thing to do.
Throughout most of human history we have had less than a billion people.
More people are alive today than have ever lived.
And you are concerned that the population will drop by a half?
Everyone will be richer and better off. The amount of pollution and resource use will be solved too. The underlying input to that is the number of people.
One third of arable land is undergoing desertification
Insects and other species are dying off precipitously
Corals and kelp forests too, entire ecosystems. Overfishing etc.
My thoughts here are that we require a certain base number of humans to continue to expand science. If we have 100M humans world wide, I do not believe we'll be capable of expanding our current knowledge base, instead, I think we'll regress.
That’s silly when AI can already make 1 person do the job of 100, and soon will be doing most of the science — it has already done this for protein folding etc. And it will happen sooner than in 30 years.
This argument you and Musk make about needing more humans for science is super strange. Because you know the AI will make everything 100x anyway. And anyway, I would rather have the current level of science than ecosystem collapse across the board.
> More people are alive today than have ever lived.
Assuming you meant died instead of lived to avoid a potentially nonsensical reading, this is not true.
It seems this factoid[0] has been around since the 1970s, and at least in 2007 it was estimated to be 6% of people who'd ever lived being currently alive [1]
[0] In the original sense of factoid - being fact-like, but not a fact (i.e. not true). C.f. android, like a man
And you are concerned that the population will drop by a half?
If you read more carefully, I am concerned by two things. A reduction to 0, and the lack of control over this. I think you don't get how the rate is continuing to decline, and further, that knowing why is important.
And I have not said we need "more humans". Instead, I said we need a base number of humans.
> If you read more carefully, I am concerned by two things. A reduction to 0, and the lack of control over this.
I think you need to drop back to reality to reassess your concerns. Barring a major disaster, there is no risk of extinction. Population decline is a factor only in economic terms, as demographics alone will require a significant chunk of a nation's productivity potential to sustain people who left the workforce. However, countries like the US saw it's population double in only two or three generations, and people in the 50s weren't exactly fending off extinction.
Population is a london horse manure problem. In both directions.
In 30 years time, people might be uploading their consciousness to computers, or colonising the moon. Making dire warnings about a concept like breeding that we might just get rid of seems foolish at best.
>We're in the middle of an extinction event.
No we are not. Lmao. Same way Horse Manure didnt snuff out life in London.

And it's only going to get far, far worse.
