A chemical reaction, by common perception, is a process involving the irreversible change in properties of the reactants and the formation of new matters (products); in conjunction, a physical reaction is a mere change in the formal appearance of the reactants while maintaining the originality of the products. This concept is essentially important in understanding the evolution of contemporary cities, where various architectural typologies acceleratively fuse under the catalysts of capitalism, politics, and culture, creating new forms of urbanism. The transformative process is sometimes explosive, like a chemical reaction, engendering innovative and revolutionary ingenuity, marking a presence in the course of human history, while some processes remain traditional, or “physical,” grounded to the core values that they derive from. Commonly, as a human tendency to be attracted to awe and possibilities, the “chemical” or more gravitating establishments offer more competitive incentives, appeal to public attention and the modern norm of novelty, become the dominant process for change and formation, overcasting the humble physical processes and eradicating deeply rooted history. The resulting products, overwhelmingly, play the scenes of our contemporary Generic City.
Rem Koolhaas, in The Generic City, proposes that global homogenization of styles in contemporary cities liberates architecture from the imprisonment of identity and that the neglect of history is an inevitable consequence of civilization’s exponential growth. Progress and rationality are roots of and ironically, the “identity” of the Generic City: “simply to abandon what doesn’t work” (Koolhaas, 1252). To stray away from the past, in Koolhaas’s view, is to rebirth. Indeed, modernization is a powerful chemical reaction that initiates opposition towards traditional, ineffective ways of design and promotes the development of new, surprising, and sometimes unpredictably wonderful outcomes of urbanism. For instance, the full implementation of public transportation systems and the corresponding buildings of services and commerce in their proximity, or the recent invention of artificial intelligent self-driving cars that become the neurons of the city’s integral network, created “systems” of life that can be efficiently and reliably replicated in different places, making the contemporary city perfectly precise. The homogenization of global cities will only continue to accelerate as supported by technological development.
On the other hand, Toyo Ito, in 建築で日本を変える2 (translated as Changing Japan with Architecture), argues that the concept of the Generic City is “horrifyingly homogeneous and extremely totalitarian,” (Ito, 37) for instance: contemporary Tokyo. Ito elaborates that “if our future is one that solely emphasizes the enhancement of precision, then it is imaginable that a society with no overhead, merely nerve-recking, and absolutely no tolerance for flexibility is born” (Ito, 40). The contemporary city of Tokyo is “a complete eradication of the history and culture, nature and harmony, and sense of community inherited from the Edo Period” (Ito, 39). The critical regionalist argues that this deeply rooted cultural heritage should guide the positions and the directions moving forward for the urban spaces of Tokyo. During the Edo Period, Tokyo City was a miraculous existence of harmony between nature and the waterfronts by utilizing topographical design; even after tremendous deformations, such as large earthquakes, the Meiji Reformation, and WWII, every rehabilitation and repair movement was planned reasonably with respect of history and by the principles of nature. Ito defines the “faith of the contemporary” as “faster, farther, and more rational,” synonymous with the notion of “progress” (Ito, 63). Ito further proposes an alternative mode of development in his summary of 4 principles:
1. Repair the relationship with nature2. Search for regionality3. Inherit the land’s history and culture4. Recreate the connections between people and social spaces
(Ito, 69). Instead of blindly sprinting into a deterministic, homogenized future, preserving the values and beauty of the past with Ito’s suggested fundamentals seems more accountable. If Koolhaas’s Generic City were an electrifying chemical process that is irreversible, leaving the resulting products becoming the “Junkspaces” (as discussed in Junkspace) of the process of human civilization, then Ito’s instructions would be more of a physical process that is transparent, tranquil, and (re)tracible. Architecture is ultimately created to celebrate humanity, where stories are valued and memories are cherished. It should not become a social machine, and the only variable to overcome that is people as agents. Lastly, Ito summarizes his aspiration in his memo: “I am unable to give high hopes for contemporary Japan at where it stands now. If we continue the negligence, the fear that “Japan” will disappear is going to exacerbate day by day. Replacing Japan after its extinction is the inorganic, hollow, neutral, wealthy, and flawless economic powerhouse that resides in the extreme East. Perhaps there are people who believe that this is alright, but this causes me to become unable to keep any relationships with them” (Ito, 44). Perhaps Edo-Tokyo was fragile but open-minded, while contemporary Tokyo is fortified yet isolated. Architecture reflects the values of the people who embody it and is therefore dynamic and ever-changing. In fact, a chemical process, as commonly misunderstood, is surprisingly reversible, however only under careful operations. The homogenization of modern cities is also evitable, however only if given sufficient care.
Architecture history is circular, and no development is irreversible nor are outcomes inevitable. Combustion is a chemical process that turns the organic, living wood into lifeless ashes, and though it seems futile to intervene, ashes can become fertilizers that help the new seedlings grow. Similarly, while many tragedies or miracles can occur in the experimentation of architectural processes, damage can be identified, mitigated, repaired, tended, and eventually become nutrients for new possibilities that can benefit mankind. Modernization of the city improves the quality of life, enhances accessible education, and democratizes public spaces. While the homogenization of contemporary cities is truly a danger to be aware of, it is important to not discredit the social and economic process of modernization, which is extremely valuable as well, and it can be elevated by incorporating more cultural components and bringing the center of design back to the people. A modern, yet heterogeneous contemporary city is a utopia that can be fulfilled, where different regions of the world can shine with their intrinsic identities while maintaining strength, energy, and empowerment.
