The world population is expected to start shrinking within this century after hitting a peak in the mid-2080s due to lower fertility levels, particularly in China, according to the latest projection by the United Nations.
I take issue specifically with the verbiage the commenter was using regarding the black death and wars. And the idea that more people = bad working conditions; less people = good working conditions when that's not the case of what was happening (which was more something like an inheritance/windfall).
In the case of babies not being born in modern times, there are a few things to consider.
One, that speech doesn't get weird and start advocating for a Handmaid's Tale Dystopia (forced repopulation for the sake of repopulation).
Two, that likely poorer people and probably certain groups will be affected disproportionately by this which is the equivalent of a silent genocide or several silent genocides
Three, that we acknowledge there are many sad factors at play as to why people aren't having children and those factors will likely get worse
Four, that we acknowledge that AI could very well bridge the worker shortage gap for some time until climate change kills everyone
The pressure we are feeling is from climate change and the rich. Hoping that there will be less humans to give everyone a break is delusional, especially because the past HAD less humans and workers had shit rights then compared to now. We aren't getting saved by anything, not even if we die or sacrifice our would-be children to the sun god.
