David Gerard, in his January 2025 blog post entitled "It's time to abandon the cargo cult metaphor," meticulously dissects the pervasive yet problematic use of the "cargo cult" analogy, particularly within the technology sector. He argues that the metaphor, frequently employed to describe imitative behaviors perceived as lacking genuine understanding, suffers from several critical flaws that render it not only inaccurate but also actively harmful.
Gerard begins by outlining the historical origins of the term, tracing it back to anthropological observations of post-World War II Melanesian societies. He highlights how these observations, often steeped in Western biases and lacking nuanced understanding of the complex sociocultural dynamics at play, led to a simplified and ultimately distorted narrative. The "cargo cult" label, he explains, was applied to indigenous practices that involved mimicking the rituals and symbols associated with the arrival of Western goods and technologies during the war. These practices, often misinterpreted as naive attempts to magically summon material wealth, were in reality sophisticated responses to unprecedented societal upheaval and a desperate attempt to regain a sense of control and agency in a rapidly changing world.
The author then meticulously deconstructs the common contemporary usage of the "cargo cult" metaphor, particularly its application within the tech industry. He demonstrates how the analogy is frequently invoked to dismiss or belittle practices that deviate from established norms or appear to prioritize superficial imitation over deep understanding. This, Gerard contends, not only misrepresents the original context of the term but also perpetuates harmful stereotypes and discourages genuine exploration and experimentation. He meticulously illustrates this point with several examples of how the "cargo cult" label is applied indiscriminately to everything from software development methodologies to marketing strategies, effectively stifling innovation and reinforcing a culture of conformity.
Furthermore, Gerard argues that the continued use of the "cargo cult" metaphor reveals a profound lack of cultural sensitivity and perpetuates a condescending view of non-Western cultures. He underscores the inherent power imbalance embedded within the analogy, where Western technological practices are implicitly positioned as the gold standard against which all other approaches are measured and invariably found wanting. This, he argues, reinforces a narrative of Western superiority and contributes to the marginalization of alternative perspectives and knowledge systems.
In conclusion, Gerard makes a compelling case for the complete abandonment of the "cargo cult" metaphor. He posits that its continued use not only perpetuates historical inaccuracies and harmful stereotypes but also actively hinders innovation and reinforces cultural insensitivity. He urges readers to adopt more precise and nuanced language when describing imitative behaviors, emphasizing the importance of understanding the underlying motivations and contextual factors at play. By moving beyond this simplistic and misleading analogy, he argues, we can foster a more inclusive and intellectually honest discourse within the technology sector and beyond.

Within the bustling metropolis of Boston, Massachusetts, the imposing Brutalist edifice known as City Hall stands as a stark testament to a pivotal era in the city's architectural and political history. Its genesis, a complex tapestry woven with threads of urban renewal, political maneuvering, and architectural ambition, is a narrative worthy of extensive elucidation. The mid-20th century witnessed a pervasive fervor for modernization sweeping across American cities, and Boston, steeped in its venerable past, found itself grappling with the exigencies of a rapidly evolving urban landscape. Slum clearance initiatives, often controversially implemented, sought to eradicate dilapidated neighborhoods, making way for ambitious redevelopment projects. This period of urban upheaval provided the fertile ground from which the concept of a new City Hall would ultimately germinate.
The existing City Hall, a structure of dignified antiquity, was deemed inadequate for the burgeoning needs of a modern municipality. Its cramped confines and outdated infrastructure could no longer effectively accommodate the expanding bureaucracy and the increasingly complex demands of governance. Thus, the impetus for a new civic center, a symbol of Boston's forward-looking trajectory, began to gather momentum. A design competition, a hallmark of democratic processes and architectural innovation, was launched, attracting submissions from a multitude of architectural firms vying for the prestigious commission. The eventual victor, Kallmann McKinnell & Knowles, presented a design that boldly departed from the prevailing architectural norms of the time.
Their proposal, a monumental structure of pre-cast concrete, embraced the Brutalist aesthetic, a style characterized by its raw, unadorned surfaces, massive forms, and exposed structural elements. This architectural choice proved to be highly divisive, sparking a maelstrom of public debate and critical commentary. Detractors lambasted the building's austere aesthetic, deeming it an affront to the city's historical character and a concrete behemoth ill-suited to the human scale. Proponents, however, lauded its audacious modernity, viewing it as a powerful expression of civic pride and a symbol of Boston's progressive spirit. The ensuing controversy, a clash between traditional sensibilities and the avant-garde, became emblematic of the broader societal tensions surrounding urban renewal and the evolving definition of architectural beauty.
The construction of Boston City Hall, a protracted and costly undertaking, further exacerbated the existing divisions within the city. Disputes over budgets, construction delays, and the displacement of communities in the name of progress fueled the flames of discontent. Despite the controversies that engulfed its creation, Boston City Hall ultimately became an undeniable landmark, an indelible fixture in the city's skyline. Its imposing presence, a constant reminder of the complex interplay of ambition, vision, and compromise, continues to evoke strong reactions, serving as a perpetual catalyst for discussions about architecture, urban planning, and the legacy of urban renewal. Its story serves as a potent microcosm of the challenges and triumphs inherent in shaping the urban fabric of a dynamic and ever-changing city.

One commenter focuses on the Brutalist architectural style of Boston City Hall, mentioning its divisive nature and how opinions on it haven't softened much over time. They also highlight the poor public reception of many Brutalist buildings, leading to their demolition in some cases, while noting Boston City Hall has managed to avoid this fate.
Another commenter draws a parallel between the architectural style of Boston City Hall and similar concrete structures in the UK, suggesting a common aesthetic and possibly shared influences. They mention the prevalence of such buildings in British town centers and university campuses, hinting at a broader trend in that era.
Building on the theme of public perception, a different commenter shares a personal anecdote about their father, an architect who worked on a Brutalist-style library. This commenter notes their father's eventual regret over the project, feeling it contributed negatively to the surrounding urban landscape. This personal story adds a human dimension to the discussion of Brutalist architecture and its impact on communities.
A further comment pivots slightly to discuss the urban planning decisions of the time, linking them to the then-prevalent theories of architect Le Corbusier. The commenter suggests that the creation of plazas and the separation of pedestrian and vehicular traffic, as seen around City Hall, were influenced by Corbusier's ideas, although their execution might not have always been successful.
Finally, a commenter provides some contextual information about the political and social climate of Boston in the 1960s, highlighting the influence of Mayor John Collins and his focus on modernizing the city. This adds a layer of historical understanding to the discussion, connecting the architectural choices to the broader political and social forces at play.
While the discussion doesn't delve into highly technical or complex architectural critiques, it provides some interesting personal reflections, historical context, and observations about the broader trends in architecture and urban planning during that period. The comments, while limited in number, paint a picture of the ongoing debate surrounding Brutalist architecture and its place in the urban landscape.
