Four urban conditions of vibrant city life and reflection on megaprojects

Assuming the bellow showed Jacobs´ urban conditions of vibrant city life and that urban megraprojects tend to make urban spaces more homogenous due to the concentration of a particular service or user profile, do megaprojects kill vibrant city life in a long term?

Jacobs argues that vibrant activity can only flourish in cities when the physical environment is diverse. This diversity, she says, requires four conditions. The first is that city districts must serve more than two functions so that they attract people with different purposes at different times of the day and night. Second, city blocks must be small with dense intersections that give pedestrians many opportunities to interact.

The third condition is that buildings must be diverse in terms of age and form to support a mix of low-rent and high-rent tenants. By contrast, an area with exclusively new buildings can only attract businesses and tenants wealthy enough to support the cost of new building. Finally, a district must have a sufficient density of people and buildings.
