There's a net new 80 million people added to the world every year.
It's already crowded af in large cities with ridiculous traffic, housing prices, crime, and air pollution (think LA, NYC, Hong Kong).
How much worse will it get before we start seeing a lack of food, energy, and resources (ie. metals) to sustain the population?
It implodes. The greater the population, the greater its problems caused. Becoming a tipping point.
It can gain greater numbers, often by advancing technology. However by changing any methods provokes the existing population not caught up. By continuously adding them into the current method causes it to tip.
The only means of adding them is by greater control, and it causes it to tip.
There is no solution. The Dystopia, has become abhorrent, like the current method adding them in to control them more. It tips. Those numbers will have to fall before they can ever hope to expand.
