@artemis I haven't got any children because I haven't got enough hope in the future of humankind. We're headed for the biggest civilisational collapse ever, and everyone who wanted to know always knew, at least after 1972 when the Club of Rome published Limits to Growth. I was born in 1975, and I became a science nerd as soon as I could read. In 1983 by the age of 8, I was well aware of the looming polycrisis towards which our civilisation was rushing at ever increasing speed. By the age of 15, I absolutely expected to see the beginning of the collapse in my lifetime. I'm 51 now, and I can see the signs of beginning collapse all over the world.

I have always been a weak and sickly person. Without modern medicine, I wouldn't have made it to my fifth birthday. It's not like I have any kind of chronical illness, I'm just a skinny person with a less than average immune system, so every infection hits me a little bit harder than most people. People like me still have a good chance of living a decent and long life within this modern civilisation, but I wouldn't last very long without it. Why should I have any children if I expect this civilisation to fail, to decline, to crumble to dust, rather soon? If I had any offspring, their chances of survival would probably be worse than average.
