On a humanity-level: yes. On an individual state-level: no.

"On an individual state-level: no." This might actually be a yes if you believe in the potential impact of automation and AI.

And if you believe in the fair distribution of the benefits of automation and AI in the population. IMHO, this belief is the more unrealistic one, at least in the short term.

> have 2 kids or fewer This is at odds with lots of other relevant topics that go beyond just "consumption". 2 or fewer is below the replacement rate of 2.1 This _has_ already happened, but there are a lot of voices voicing a lot of reasons why they believe that that might actually be not the best situation.

You see a whole lot of panic from industrialists over the birth rate drop in the industrialized world. They claim it is an extinction level event for humanity. This is not quite correct. It is an extinction level event for economic models that assume unbounded growth of the consumer base.

This is an important distinction: what is good for ecology is not necessarily good for economy.

If we need unbounded growth to jeep our economic system to function, its the economic system that is wrong, not nature.

>Below replacement would be terrifying if there were one thousand humans, The funny part is that it should terrify you whether there are 10 humans or 10 billion. At the current rates, it's over in about 12-13 generations regardless of the number you start with. That's how it works... no matter how big the starting number, it's how many generations you have left. Think of it this way? You know the dumb story they taug…

This whole comment rests on a very big assumption that these rates will never recover. Just because you can fit a trend line doesn’t mean the projections will pan out. It could just as easily be the case that once population starts meaningfully decreasing, the opportunity cost of children will also decrease and fertility rates will recover. This happens all the time in nature. Our population absolutely exploded over…

>This whole comment rests on a very big assumption that these rates will never recover. J

The opposite, actually. Your assumption is that the rates bounce up and down, mostly because you don't want to believe there's a problem.

The rates are transmissible, older generations to the younger. No one growing up in a world where people have few or just one child will say to themselves "hey, you know what, I want 10 kids when I'm an adult!"... but that's what would have to happen. You and everyone else on HN whines "the reason people aren't having kids is the economy is awful and we can't afford them"... but in a world with a shrinking, aging population the economy just gets worse.

You're the one making the very stupid assumption, and you can't even say why. I can, it's because you haven't thought about it. Perhaps it's uncomfortable to think that you're driving your species to extinction.

>Our population absolutely exploded over the last 100 years.

More nonsense. Our population isn't exploding, it's just big. And it will shrink rapidly. I already laid out the math... how long before 8 billion becomes 1000 when you're splitting it in half every generation (a generation is commonly held to be 20-25 years)? Can you do that math puzzle for us? There are only about 5 generations living on Earth at any given time. Just do the math already. None of this is pretty.

>There really is no reason to be worrying about human extinction right now.

Yes, there is. People are only generally capable of reproduction from the ages of 16 to 36... just 20 years. Every moment you waste "not worrying about it now" is the problem compounding with interest. You've already waited too long to worry about it.

>In fact, the ‘extinction’ rhetoric is harmful and dangerous since so many ‘solutions’ to fertility rates are less education and less freedom.

Well at least when our species dies out, the last few people will have masters degrees. That's the important part, right?

>I have no trouble believing a handmaids tail like faction emerging

It'd be because you and those like you forced the issue. Go ahead, stick your head in the sand some more. We all know that willful obliviousness to reality can change the rules of the universe themselves, right? Wish it all away!

I recently finished rewatching The Three Body Problem in which (spoilers follow) the world panics and goes into overdrive because an alien invasion is due in... 400 years. If the current climate trends continue, vast areas of the Earth may not be suitable for habitation within half that time, and we still can't seem to convince some people this is real. Granted I was a climate change skeptic myself until about 10 yea…

What's that scientific saying about correlations and causations? But, yeah, let's all go back to middle ages pre-industrial economy just in case.

This isn't that hard to understand. If you have ever gotten in your car after it has been parked in the sun, you know about the greenhouse effect. That CO2 does the same thing isn't some weird mystical thing. It's basic science. We know exactly how the causation works.

> the world panics and goes into overdrive because an alien invasion is due in... 400 years. It's the difference between Chinese planning philosophy versus the West's.

Not really. There are plenty of Western entities that think in centuries (e.g. the Catholic Church) and plenty of.Chinese entities that are chasing the next moment (all the companies who cut standards on product because "to them it is the same"). This is true about the instantaneous state of the governments of the US and China rather than some intrinsic permanent cultural quality.

Yes, I meant current governments not culture itself.

I guess that’s what parent meant. But just because it’s also their fault doesn’t hinder them to blame the government. Who do you think will MAGA blame for the consequences of climate change?

Woke black people who sleep with members of their own gender!!

Stupid woke climate.

I’ve come to terms with the fact that there is no stopping human consumption. It is simply not possible to get enough people to reduce to make an impact. The failure of the environment movements over the last 60 years are proof. The only way is ‘up and out’ developing clean, cheap methods of energy generation and lobbying to get that infrastructure built out as quickly as possible. At this point, investing more in Fo…

> anyone claiming “coal” or whatever is the future is simply a conman or a clown. I've seen people on social media seriously claiming that coal plants are cleaner than wind energy or solar energy. It's aggravating. Never mind that it's easy to show that for the same amount of energy output, you get a similar amount of tons of coal ash yearly to the amount of materials it went into building a wind or solar plant... I…

The "shill" phenomenon goes much further than ignorant laypeople.

The AMOC shutdown isn't merely "possible" and due "this century". The math of the dynamics of complex systems shows the current behavior to be signs of a phase transition in the process of happening. The speed of that shutdown isn't "decades" either, it's more likely just years.

The voices of "experts" telling you it was all some incomprehensible conundrum should deeply worry you. They're either not being honest or they're no experts.

Could we put underwater data centers there to reheat the waters?

is fascinating that a software developer can have such a lack of awareness of the relative size of things

Why? Software developers aren't some superhumans, we're generally very bad at things outside our immediate area of expertise. Just like everyone else

The crazy thing is that we have basically everything we need right now. You can live in a well-insulated fully electric home powered by renewable energy and have most things you need within a walk, bike, or public transport ride away, _OR_ use an electric car for the things that aren't. If you combine that with a mostly-plant based diet (or at _least_ swapping chicken for most of your beef and lamb) and have 2 kids o…

>The crazy thing is that we have basically everything we need right now. Have you travelled? This doesn't describe most of the world. Most of the world would need to increase carbon emissions to live the way you're describing. You aren't describing a zero carbon lifestyle, you're describing a lower carbon lifestyle. And we still use carbon in building the things in your scenario: the building, the car, etc. Lower car…

The idea of average individuals being the relevant actors in global carbon emissions is pure misdirection. They're not, it's systemic with industry being the main culprit and the rich being the ones who benefit from that socialization of pollution costs.
