Arcades,malls,mega malls, whats next?

In Walter Benjamin’s The Arcades Project, he is mostly explaining about arcades and their roles in people’s lives and the economy. The arcades were used as a place where corporate markets would all get together and sell items to customers. Arcades changed the feel of the retail experience because instead of retail stores being in an individual entity, arcades bought stores all together into one place and under one roof with a variety of different retail stores. Arcades also bought a different people throughout the same and different neighborhoods into one same gathering space and interaction between these people would happen. Eventually these arcades became malls which contain department stores, individual stores as well as people, which were all put together into one roof. It changed the way the economy worked as well as the architecture involved in creating these spaces in arcades.
The 20th Century malls are similar the arcades but bigger. However, the 21st Century malls such as DestinyUSA and the South China Malls have the same ideas as arcades and malls, but they are way bigger and are like arcades on HGH and Winstrol together. It’s a scary thought to think how much energy will be used to upkeep these places as well as what the next step would be after the mega malls. Sooner or later, it wouldn’t surprise me that somewhere in the near future, these malls would be so big, it would become its own city.
