Final answer:
Urbanization has led to challenges such as traffic congestion and socioeconomic divides, with urban areas in developing countries facing significant growth management issues. While cities offer economies of scale, these can turn into diseconomies when congestion and pollution rise, impacting the future success of urban planning.

The future success of cities, both in developed and developing countries on their ability to mitigate such issues while capitalizing on the economic advantages of urban living.
