We interact with people and environment on a daily basis. However, we solely pick up the impressive moments based on 5 senses. Likewise, the cities consist of invisible memories and emotions through the relationship. It is transformed and evolved by various geometric or organic shapes and loses increasingly the original substance. The cities regardless of being truly connected remain only loneliness.
Eventually, we human might not be seen our ideal cities because we only build up cities in our own memories. This is an image what I think and see in this paragraph.

Genoese pirates and put in irons in the same cell with a writer of adventure stories. It is not the voice that commands the story: it is the ear.”
