Why do humans refuse to leave useful things merely useful?
A truck does not need a peacock to carry freight.
It does not need poetry painted across its body, mirrors along its sides, or colors bright enough to announce its arrival before the engine does. None of that makes the cargo lighter or shortens the road.
And yet Pakistani trucks have long been decorated with poetry, repeated patterns, figurative images, and religious and secular inscriptions. The decoration can express something about the people around the vehicle, including their religious identity. It is not simply paint applied to machinery. It turns a working object into a social one.
In 2001, while preparing for the following year’s Silk Road Folklife Festival in Washington, anthropologist J. Mark Kenoyer bought a 1976 Bedford truck in Karachi. Two craftsmen were brought in to transform it. Jamil Uddin rebuilt the body with steel, chrome, and mirrors, while Haider Ali covered it in vivid painted designs. The truck was shipped from Karachi and eventually hauled across the United States to the National Mall, where the two men demonstrated their craft during the 2002 festival.
Remove everything they added and, mechanically speaking, the truck remains a truck.
Which raises a simple question:
Why bother?
Humans have never been very good at leaving useful things alone. We carve handles that would work just as well if they were smooth. We polish metal that would perform the same job dull. We paint vehicles, embroider work clothes, shape teapots, decorate tools, and hide mechanisms inside beautiful cases. Sometimes we do the opposite and expose the machinery because watching it work is part of the pleasure.
We make things to solve problems. Then we start deciding what the solution should look like.
Those decisions are not as frivolous as they seem.
A famous experiment published in 2000 asked participants to interact with computerized systems modeled on automated teller machines. Researchers Noam Tractinsky, A. S. Katz, and D. Ikar wanted to know whether people’s impressions of a system’s appearance affected their sense of how well it worked.
They did.
Participants’ judgments about aesthetics were strongly associated with their judgments about usability, and the researchers found that appearance influenced how usable the systems seemed after people had used them.
Later research complicated the appealing idea that “beautiful is usable.” A 2012 study found cases in which aesthetics did not improve perceived usability. Instead, actual usability shaped how attractive the interface seemed afterward. A frustrating object could begin to look worse simply because it had frustrated us.
That may be the more interesting finding.
Beauty and usefulness do not always occupy separate rooms. We experience objects as wholes. The button that feels good to press, the handle that sits naturally in the hand, and the machine whose controls make immediate visual sense all affect our judgment before, during, and after use. Even a polished surface can suggest care before we know what lies beneath it.
There is an entire branch of philosophy concerned with something we practice constantly without naming it: everyday aesthetics.
For much of modern Western philosophy, serious attention was reserved for art. Everyday aesthetics looks elsewhere. It asks us to consider the sensory and emotional qualities of eating, walking, bathing, dressing, cleaning, using tools, and moving through ordinary environments. It is interested not only in beauty and ugliness, but also in the messy, gaudy, pleasant, irritating, and monotonous textures of daily life.
The museum does not have a monopoly on aesthetics.
Neither does the designer chair.
The object you touch twenty times before lunch qualifies. So does the machine.
Once we begin looking at machines this way, another possibility appears: perhaps beauty is not always something added to function. Sometimes function itself is beautiful.
In Functional Beauty, philosophers Glenn Parsons and Allen Carlson revisit an idea with very old roots. A review of their argument begins with Xenophon’s Socrates and an unglamorous example: even a dung basket might be beautiful if it is well made for its purpose. Their larger argument is that understanding what an object does can be part of appreciating how it looks.
That is different from painting flowers on a truck.
It suggests that we might admire the curve of a tool because we understand why it curves. A bridge can become more beautiful when we see how it carries its load. A mechanism can be satisfying to watch because every part appears to be doing exactly what it should.
Few places make that relationship between function and performance more visible than an Italian coffee bar.
In 1961, the Milanese company Faema introduced the E61 espresso machine.
Technically, it changed espresso. An electric pump delivered water at constant pressure, while a heat exchanger allowed the machine to draw water from the mains and produce coffee continuously instead of waiting for a boiler to recharge.
But one of its most important changes was almost architectural.
Earlier commercial espresso machines could be tall and imposing. In the E61, the boiler was turned horizontally, bringing the machine down to roughly twenty-two inches.
A barista could see over it. More importantly, a barista could talk over it.
Historian Jonathan Morris has argued that the E61 helped reshape not only the drink but also the business model and ritual of the Italian coffee bar. Its steam wands were positioned so that a bartender could prepare much of the coffee from one place, and its continuous delivery suited small establishments where one person might be working alone. It became Italy’s bestselling coffee machine of the 1960s.
Engineering changed the silhouette. The silhouette changed the interaction, and the interaction helped shape a ritual.
The machine became beautiful partly because it made its function visible: chrome, controls, steam, cups, hands.
An espresso machine does not disappear into the kitchen like a dishwasher. It occupies the bar. We watch it work.
That is one kind of beautiful machine: one whose performance becomes part of our own.
There is another kind standing beside a road in Japan.
It may be white, with a bright grid of canned coffee, tea, water, and soft drinks behind its illuminated face. At night, it can appear brighter than almost everything around it.
There is nothing extraordinary about this. It is a vending machine.
That ordinariness is precisely what interested Japanese photographer Eiji Ohashi.
Ohashi lives in Hokkaido, where winters can be severe. He has written about encountering vending machines not only in cities but also in mountainous areas, at promontories, beside dead ends, and outside people’s houses. They were ordinary enough to disappear into the landscape.
Until one helped him find his way through a snowstorm.
While living in Wakkanai, in northern Hokkaido, Ohashi became disoriented during severe weather and used the light from a vending machine to establish his location. He began paying attention to the machines. One snowy night, he noticed the shapes created when their light fell across fresh snow, and he started going out before the snowplows arrived to photograph them.
Nothing had changed about the vending machines. What changed was the looking.
This problem—how we stop seeing the things we see constantly—sits at the center of everyday aesthetics. Philosophers have given one response to it a name: defamiliarization.
Practical life can hide the aesthetic possibilities of ordinary things. We are trying to get home, buy coffee, catch a train, or find our keys. The object in front of us is mainly a means to some other end. Change the way we attend to it, however, and the ordinary thing becomes visible again.
Photography is particularly good at this. Put a frame around something and suddenly it has to defend its existence.
Ohashi’s vending machines stand beneath snow and beside roads, glowing against landscapes that would otherwise be dark. A machine designed to sell a warm bottle of coffee becomes a source of light. A commercial object becomes part of the scenery.
In Ohashi’s account, the practical and aesthetic experiences remain intertwined. He remembers holding a warm drink from one of these machines during a Hokkaido winter and feeling himself relax. He remembers the light that helped him orient himself in a storm. After the 2011 Tōhoku earthquake and the power-saving campaign that followed the Fukushima nuclear disaster, vending machines were criticized as wasteful consumers of electricity. Yet Ohashi also writes that machines were installed in badly affected areas of Iwate and Miyagi during reconstruction to supply drinks to workers and residents.
A vending machine can be convenient and wasteful, commercial and comforting. In the right moment, it can even become infrastructure and light.
That is why “beautiful” is such an inadequate word for what aesthetics actually does.
Beauty can make us notice an object. But objects can also become beautiful when we notice what they do.
There was a time when one enormously influential European architect wanted modern people to stop decorating useful things almost altogether.
Adolf Loos delivered the lecture that became Ornament and Crime in Vienna in 1910.
The title was not subtle.
Loos argued that cultural development involved removing ornament from everyday objects. In his view, ornament wasted labor, material, money, and time. If an object could physically last for years but its fashionable decoration became intolerable sooner, the labor embodied in it had effectively been squandered.
There is something unexpectedly contemporary in that complaint: buy less, make things that last, and do not make an object aesthetically obsolete before it is physically obsolete.
But Loos built the argument on a hierarchy inseparable from the racism and colonial thinking of his period. His essay repeatedly contrasts the supposedly advanced modern European with people he describes as primitive or culturally behind, using ornament as evidence of their place on an imagined ladder of civilization.
The plain object was not merely a matter of taste. In Loos’s argument, it became evidence of advancement.
Set that idea beside a Pakistani truck and the truck begins asking uncomfortable questions.
Who decided that less decoration meant more progress? Why should usefulness become purer when personality is removed from it? And why assume that time spent decorating an object is wasted?
There is no need to turn this into a simplistic contest between a minimalist West and an ornamental East. European history is full of ornament, from Gothic stone carving to Baroque churches and Art Nouveau ironwork. Japanese aesthetics cannot be reduced to restraint either. Cultures contradict themselves too enthusiastically for that.
Still, the modernist suspicion of ornament is real.
So is another tradition that looked at useful objects and saw something else.
In Japan in the early twentieth century, philosopher and critic Sōetsu Yanagi championed the beauty of ordinary handmade objects used in daily life. He coined the term mingei for folk crafts made largely by anonymous artisans. The movement directed aesthetic attention toward objects associated with clothing, food, housing, and everyday use rather than things made primarily to sit in galleries.
The useful thing did not have to overcome its usefulness to become beautiful. Its usefulness could be part of its beauty.
That idea returns us to the truck.
At the 2002 Smithsonian Folklife Festival, visitors could watch Haider Ali and Jamil Uddin work on the Pakistani vehicle displayed on the National Mall. Photographs in the Smithsonian archive show painted panels, metal ornament, mirrored surfaces, and visitors climbing into the cab.
Academic research on Pakistani truck decoration describes vehicles carrying poetry, patterns, figurative imagery, and epigraphic formulas, some religious and some not. These visual programs can communicate information about religious identities and changes within Pakistani society.
The decoration, then, is doing something. Not the mechanical work of the truck, but another kind of work. It communicates and distinguishes. It makes identity visible. It gives a standardized industrial object a particular social life.
A factory can manufacture a truck. Culture can turn it into this truck.
Perhaps that is where the original question begins to break apart.
Why do humans make machines beautiful?
Because “beautiful” describes too many different things.
The Pakistani truck is not doing aesthetically what the Faema E61 does, and the E61 is not doing what Ohashi’s vending machine does. One is deliberately ornamented. Another makes engineering part of a public performance. The third becomes powerful because familiarity is interrupted and an ordinary object is seen again.
Beauty can be applied, emerge from function, or be discovered.
Sometimes aesthetics does something stranger still: it allows a machine to survive after it is no longer necessary.
Consider the jukebox.
There are much easier ways to play a song now. A phone contains access to more recorded music than the designers of the first coin-operated machines could have imagined. There is no practical reason to keep a huge cabinet in a room so that a mechanical system can select one physical record and play it.
And yet people restore them.
Part of what they are preserving is the inconvenience: choosing a song, pressing a button, waiting for the mechanism, watching the lights come on, and seeing the machine begin to do what you asked.
Efficiency tends to eliminate such moments. Press a screen and music appears. Press another and it stops. As technology becomes better at performing its function, there is less machinery left for us to perceive.
That is not necessarily a loss. Nobody should have to crank a mechanism merely because gears photograph beautifully. Good design can be quiet, and an object that removes unnecessary friction may be doing exactly what its designer intended.
But what happens to our emotional relationship with machines when the machinery disappears?
We live increasingly among objects whose complexity is concealed behind smooth surfaces. A phone gives few clues to its internal operation. The television has become a dark rectangle. Controls migrate into screens, physical buttons disappear, and machines communicate through interfaces rather than mechanisms.
Perhaps this is simply another aesthetic: the polished plane instead of chrome piping, the animation instead of the lever, the seamless surface instead of the visible gear.
The beautiful machine has not vanished. We have changed what we ask beauty to say about it.
Ornament might announce labor, status, craft, or abundance. Exposed engineering can suggest precision and power. Minimalism can signal technological sophistication: nothing appears difficult because the difficulty has been hidden.
None of these aesthetics is neutral. Each proposes a different relationship with the object.
Admire it. Understand it. Trust it. Recognize it. Touch it. Watch it.
Or, increasingly: do not think about it at all.
The most successful machine may be the one that disappears into the action it performs.
But disappearance has consequences. A machine that becomes invisible may be easier to replace. One we understand poorly may be harder to repair. A mechanism we never see can feel less like an object we possess than a sealed service we temporarily inhabit.
This is where the old argument about function and beauty becomes unexpectedly current.
The question is not whether machines should be decorated. It is what aesthetics makes possible between a person and a thing.
Research on interfaces suggests that appearance can influence our judgments about usability, even if the relationship is more complicated than the slogan “beautiful things work better.” Everyday aesthetics reminds us that seemingly minor aesthetic judgments shape ordinary life. Functional aesthetics suggests that understanding what an object does can be part of appreciating how it looks. Craft traditions show that usefulness and beauty never needed to be enemies.
The machines themselves offer less theoretical answers.
A coffee machine changes shape so the person operating it can talk to the person drinking from it. A vending machine becomes visible because its light falls across snow. A working truck becomes a moving surface for poetry, belief, imagery, and identity.
None stops being useful.
Beauty does not necessarily distract from function. Sometimes it explains it. Sometimes it celebrates it. Sometimes it gives us a reason to keep looking after an object long after something faster has arrived.
And sometimes it does something with no measurable efficiency at all.
That may be the hardest possibility for a culture obsessed with optimization to accept.
Humans do things beyond necessity. We always have. We embroider cloth after it can already cover the body, glaze a vessel after it can already hold water, carve a handle after a tool can already be held, and polish a machine after its mechanism already works.
The unnecessary part is not necessarily waste. It may be where the person enters the object.
Go back, finally, to the truck.
Steel, engine, wheels, freight. Everything required for the job is already there.
Then someone paints a peacock.
The peacock will not make the truck faster, improve its fuel economy, or increase the weight it can carry. Measured against the vehicle’s mechanical purpose, it is useless.
But perhaps that is the wrong measurement.
The truck was built to carry freight. The peacock tells us that a human being was there.
That may be why we have never been content to make useful things merely useful.
