The thing is when countries industrialize, they tend to have birthrates below replacement rate because they don't need to have children to have farmers.
The reason the population of the world is still booming is because countries like India, China, African countries, etc are still having kids to be farmers because their country is still mostly rural, which I don't see these countries randomly getting bombed and reverting back to a farming civilization.
But its gonna be interesting to see when more developed countries have less people and less developed countries have more people.
And even if the education system goes through some major changes, we will be needing skilled labor and college educated people soon enough.
The babyboomers are aging rapidly and dying. There are no more kids in line to take over their positions. Gen Z and Gen Alpha won't have to worry about job replacement for a good 15-20 years, but once the final wave of boomers die out, there is going to be a serious crisis of needing replacements in the workplace.
Industrial civilization is the reason why the world population rose from 1 billion to 7 bilion... its collapse means we go back to 1 billion, because thats how much you can feed without industrial civilization. african population rose from 100 mn to 1 bn, and if these guys get their way, africans are the first to go.
they are the closest to the starvation line
imagine the graph where the starvation line just goes up, and the closest ones are to fall below it first
you will survive alright, but the guy who lives on 1 dollar a day is gone.
