If the social media of the past decades teaches us something, is that when given the chance, people tend to form cliques and tend to stay in their bubble when they find one. This persists in large cities where people have adequate and constant exposure to alternate cultures. Maybe people have gotten tired of trying to be tolerant to everyone, maybe they don't see enough value in having to resort to lowest-common-denominator communication and cultural memes. Maybe in the future the physical layout of cities will come to represent its ideological /cultural layout. As loneliness is a physical thing, maybe bringing compatible people closer together enhances communication.
