Reading this description of the dichotomous Cairo immediately brought to mind the scene in which Hanouma and Qinawi have a dialogue by the fountain [28:20 - 28:42]. When Qinawi stands up, we see the statue of Ramses II in the background for a second--and the insert shot of Hanouma's gaze / reaction at [28:23] further brings our attention to the Qinawi-Statue two-shot. I felt that, in parallel to the reading, this scene establishes Qinawi as the "old" Cairo, unchanging in its pursuit of unrequited love, "unable to struggle against progress", and rather delusional in his fantasies and obsessions; on the other hand, Hanouma remains sitting with the clean and modern fountain in the backdrop, making it quite easy to then associate her to the "new" Cairo, "ever changing" and "infinitely more attractive".
Moreover, the content of their dialogue, especially when Hanouma breaks out of their daydreamy talk to scold Qinawi ("Use your head. Look around. I work hard for a living, selling drinks [...] Get a grip on reality. I've had enough.") further embodies the dichotomy described by the author regarding the "old" and the "new" and their incongruous coexistence.
