The lightcage (limit of speed of light travel) will kick in faster than you would expect. I believe it is less than 1000 years at current growth rates. It's like compound interest.
Everyone has heard for DECADES that overpopulation is a problem, soon as humanity self-corrects though its "oh no what about our lack of disposable factory workers". I don't like living on this world can someone take me to the horse head nebula or something
"Overpopulation" is a theory that was floated about for a little bit in the middle of the 20th century. It was quickly disproven on all grounds, but it's a convenient oversimplification so it held on anyway.
There's enough food and water and housing for everyone out there. We just can't figure out how to assign our resources fairly and without enormous amounts of waste.
Long-term this is a good thing imo. We are too dominant as a species and offering a same high quality of life to 10 billion people (in 2050) just doesn't seem possible. With less humans, the world would be a better place for the remaining humans and animals. With which I'm not saying that less humans alone will be enough to offer everyone on earth a high quality of life, it just would make it a lot easier to achieve that utopia.
"Livestock make up 62% of the world’s mammal biomass; humans account for 34%; and wild mammals are just 4%."
The population has more than doubled since I was born and the quality of life for an average person definitely seems lower. Plus everything is so crowded, all the time. It doesn't feel good. Also, companies don't even need to make their products good because there are billions of people who will buy them anyways.
This average trend has been some kinda scientifically forecasted.
Mostly industrial countries like in NA and EU f.e. are going down with general birthrate etc, as it's not necessary to get by when older (well.. I have doubts regarding this).
So called third world countries are going up in births, because children secure their later life.
It is expected that the global population will go back down by the year 2100, but also will have the highest amount or peak of 10 billion by 2050.
I cannot back this, since I have read about this years ago and things might have drastically change, since a lot of factors do change unexpectedly.
There is maybe one country in the entire world where births are going up. The gist of your argument is correct, but it's not "births going up" but "the birth rate is still higher than in rich countries, even though it's been going down for a while". The general pattern that all countries go through is from high birth rate and high death rate to low birth rate and low death rate. It's just that death rate goes down way faster, because it's mostly dependent on technology, and birth rate going down requires significant behavioural changes. The population explosion in poorer countries is because death rates have gone down way faster (lots of change arrivibg suddenly) than they did in the rich countries (where thus all happened long ago, as the technology was invented). Look up population transition if you want to know more.
This is basically it. This has nothing to do with an economic model, it has to do with education and industrialization. There are countries out there paying people to have kids, and it's not really enticing people to have them, because people want to travel and enjoy their lives.
As of today all continents, but Africa, have a below replacement fertility rate. Current forecasts are Asia and Latin America peaking between 2055-2060, Europes population falling even earlier and North Americas population growing very slowly. Peak global population is supposed to be around 2090. Although there is quite a bit of evidence of this happening earlier, as population growth in Africa seems to fall much quicker then expected and countries like China are shrinking faster then expected too.
