Have we hit the peak size for cities? They'll grow for a little while longer from people moving into them from the countryside, but then they stop having kids and the cities will just keep shrinking once everyone's moved to them. European cities will keep growing from immigrants, but the Asian megacities must have hit their maximum population by now. Unless at some point smaller cities also start losing people to the one or two largest ones, let's say some tier 3 Chinese town of one million people just gets abandoned and they all head to Shanghai or somewhere
