That's the very pessimistic view. We have the longest peaceful period ever at least in the Western world and access to infrastructure previous generations could only dream about. It's true overpopulation in areas not suitable for sustaining big populations is a problem but it's difficult to predict how it plays out. It's not that people needed much reason to start wars in the past and it seems we've reached quite a stable state now at least from historical perspective.

I mean I still have living family members who remember their homes taken away, being packed on the train and transported to Syberia by Soviets so it's very hard for me not be grateful for the kind of world I get to live in.
