Essential Reads for Software Engineers

The software engineering world moves fast, but some ideas endure. Constantinos Psomadakis’s essay, "The Pendulum of Taste," offers a timeless perspective on how trends cycle back. It’s a great starting point for understanding the ebb and flow of design and technology, reminding us that what feels new today might echo the past tomorrow. This piece sets the stage for exploring other essential readings that provide lasting wisdom for developers.

1. The Pendulum of Taste by Constantinos Psomadakis

Constantinos Psomadakis's essay, "The Pendulum of Taste," from The Pendulum of Taste, posits that aesthetic preferences move cyclically, swinging between nostalgia and futurism rather than progressing linearly. Key concepts include interest decay, timeless taste, and the cyclical nature of design trends. Psomadakis uses examples from Apple's iOS design, the vinyl record resurgence, and fashion to illustrate how reactions to current trends eventually lead to an overcorrection and a return to older aesthetics. He emphasizes observing the direction of change over current position.

Psomadakis argues that taste doesn't move forward in a straight line. Instead, it swings like a pendulum, with movements often starting as reactions to what came before. As these reactions become established styles, they can eventually overshoot, making the opposite feel appealing again. This dynamic is evident in design shifts, such as Apple's transition from skeuomorphic design with iOS 7 to a flatter aesthetic, and its more recent introduction of "Liquid Glass" in iOS 26, which reintroduces physical and imperfect elements. This swing back towards more tactile design echoes broader cultural trends.

Beyond digital interfaces, this cyclical pattern is visible in other areas. The resurgence of vinyl record sales, mirroring levels not seen since the late 1980s, exemplifies this. Similarly, film cameras are seeing renewed interest, and fashion trends from the early 2000s are reappearing. Psomadakis suggests this turn towards older aesthetics occurs even as technology accelerates, creating an interesting dichotomy where a more automated and digital world sparks a renewed appreciation for the tangible qualities of past objects and styles.

The concept of "interest decay" explains how novelty fades as trends become mainstream. What once signified individuality can become ordinary, changing its signaling value. When a taste becomes too widespread, it loses its appeal, prompting people to seek the next thing that differentiates them, thus pushing the pendulum. This decay is not necessarily negative; trends can introduce people to new experiences. However, as Psomadakis notes in "The Pendulum of Taste," when something becomes excessive, the natural reaction is a swing in the opposite direction, moving from perceived perfection to an appreciation of imperfection.

Ultimately, Psomadakis suggests that truly "timeless taste" is often found in designs that have successfully navigated multiple swings of the pendulum. These enduring works remain compelling regardless of the prevailing aesthetic. He posits that great designers don't necessarily chase trends but focus on fundamental problem-solving, which paradoxically allows their work to endure. By observing the direction of change—the gradient of the curve—rather than just the current position, one can better anticipate future aesthetic shifts. Constantinos Psomadakis's essay provides a valuable framework for understanding these dynamics.
