There are 8.3 Billion people on the planet and there were 7.5 ten years ago. We have enough people. We have enough resources for everyone to live comfortably and be well in their communities. We have more than enough money and other valuable things to trade.
The main thing getting in our way isn’t a low birth rate.
Anyone genuinely concerned with the depopulation of humans in 2026 is probably some flavour of breeder cult weirdo, and the only ones constantly banging on about it in politics, academia, the news, etc are imperialists, industrialists and racist patriarchs. IME.
Having worked in the homes of very wealthy folk, I can confirm that “move fast and break things” was always missing the part where the rich bastard’s nanny/gardener/housekeeper/etc takes the blame for shit being broken and gets their pay docked, while the Baby Elon-Zuck-Altmans of the world get an ice cream and a snuggle. Same shit happens when they grow up to be Big Boys.
