In 50 years we will have a massive population collapse, the US have been below replacement level for 50 years. China is even worse.
Prepare yourself to see massive employees shortage getting worse and worse.
The only thing keeping population aflot is longevity extension but 80yo don’t produce or consume much.
I can't find any serious prediction of imminent collapse.
The result is that it’s not apparent when you look at population. But aging is having a massive effect on the economy, the job sector, etc.
At some point it’s going to collapse, but because we have been below replacement for a long time it’s not going to stop anytime soon.
Look at Japan, Italy to see what is coming (they are a bit ahead) Last year japan lost 800 000 of population. At some point the japanese culture will disappear if they don’t start having babies (really not happening at the moment)
I heard that in Japan they sell more adult diaper than baby diapers...
So we have more living people but they are older and older. At some point it will fall unless we find more and more way to extend lifespan. https://ourworldindata.org/grapher/children-per-woman-by-gdp...
The presence of many degrees of freedom does not make them all equally influential.
For climate in 50 years... Where humans will be. Consider that the internet was at the beginning 20 years ago.
Where was solar and EV 20 years ago.
I am bullish on human creativity, much less so on Deloitte and the governments.
