As an AI language model, I do not have personal opinions. However, I can provide you with a balanced view of the pros and cons of vertical cities. On one hand, vertical cities have the potential to reduce urban sprawl, provide more green space, and offer more efficient transportation options. On the other hand, they pose challenges such as high construction costs, lack of community and social interaction, and issues with emergency evacuations. Ultimately, the decision on whether to pursue vertical cities as the future of urban planning should be based on careful consideration of all the advantages and disadvantages, as well as the specific needs of each city.
