When Everything Becomes Everything Else

Your phone is a camera. It's also a television, a newspaper, a gaming console, a compass, a flashlight, a calculator, a voice recorder, and a video editing studio. None of this surprises you anymore. But step back for a moment and consider how strange this is.

A century ago, each of these devices existed in separate worlds, manufactured by different industries, sold in different stores, used by different people for entirely different purposes. The telephone belonged to the communication business. The camera belonged to photography and film. The newspaper was printed on massive industrial presses. Each technology had its own experts, its own supply chains, its own economic logic.

Now they all live in your pocket, inseparable, merged into a single glowing rectangle.

This phenomenon—the gradual fusion of technologies that began as strangers to one another—is called technological convergence. And it's reshaping not just the devices we use, but the industries that make them, the workers who design them, the companies that profit from them, and the societies that organize themselves around them.

What Convergence Actually Means

At its simplest, technological convergence is what happens when unrelated technologies develop along paths that eventually intersect. The watch and the computer had nothing to do with each other in 1975. By 2025, it's almost odd to encounter a watch that isn't a computer.

But convergence runs deeper than gadgets merging. One researcher describes it as "a deep integration of knowledge, tools, and all relevant activities" aimed at allowing society to answer questions it couldn't answer before. When technologies converge, they don't just combine—they unlock new possibilities that neither could achieve alone.

Think of it this way. A camera takes pictures. A telephone transmits voice. Neither, by itself, enables video calling. But when camera technology and telephone technology and internet technology and display technology all converge in the same device, suddenly grandparents can see their grandchildren's faces from across the ocean. The whole becomes radically greater than the sum of its parts.

The opposite of convergence is divergence—technologies splitting apart into specialized niches. And sometimes you see both happening simultaneously. Media content is converging, with the same story appearing as a film, a book, a video game, and a toy line. But the hardware to consume that content is actually diverging, with specialized devices for gaming, for reading, for watching, for listening. The ecosystem is complex, and the simple story of "everything becoming one" doesn't quite capture it.

The Digital Foundation

Why is convergence happening now, and happening so fast?

The answer is digitization. Every type of information—text, images, sound, video, sensor readings, financial transactions—can be broken down into the same fundamental units: ones and zeros. Binary digits. Bits.

This sounds technical, but its implications are revolutionary. Once everything is expressed in the same language, the barriers between media types start dissolving. A photograph is just data. A song is just data. A phone call is just data. And data doesn't care what hardware processes it or what wire carries it or what screen displays it.

Before digitization, the tools were locked to their media. A film projector couldn't play a vinyl record. A radio couldn't show photographs. Each medium required its own specialized equipment, its own distribution system, its own industry. But when everything becomes data, a single device—a smartphone, a computer, a smart television—can handle all of it. The same fiber optic cable that carries your phone call also carries your streaming video, your email, your bank transfer, and your video game.

This is why one scholar defines convergence specifically as "the coming together of telecommunications, computing, and broadcasting into a single digital bit-stream." Three industries that grew up separately, serving different purposes with different technologies, are now running on the same digital infrastructure.

The Alphabet Soup of Converging Sciences

Convergence isn't limited to consumer electronics. At the frontier of science, researchers are watching once-separate fields merge into new hybrid disciplines.

You'll sometimes encounter acronyms that sound like spy agencies: NBIC, which stands for Nanotechnology, Biotechnology, Information technology, and Cognitive science. Or GNR: Genetics, Nanotechnology, and Robotics. Or GRAIN: Genetics, Robotics, Artificial Intelligence, and Nanotechnology. Or, most evocatively, BANG: Bits, Atoms, Neurons, and Genes.

These acronyms represent a bet that the major scientific revolutions of the coming decades will happen at the intersections. When you can manipulate matter at the atomic scale (nanotechnology), understand and edit the code of life (genetics and biotechnology), build machines that think (artificial intelligence and cognitive science), and connect everything through information networks, the combinations become explosive.

Consider DNA data storage. This is exactly what it sounds like: using the molecules of life to store digital information. DNA is remarkably dense—a single gram can theoretically hold 215 petabytes, or 215 million gigabytes. It's stable for thousands of years. And we already have molecular machinery to read and copy it, refined by billions of years of evolution. Researchers are now encoding digital archives into synthetic DNA strands. The technology of computing is converging with the technology of biology.

Or consider bioelectronics: circuits inspired by how neurons communicate, materials that interface with living tissue, sensors that can be implanted in the body. The hard boundary between machine and organism is becoming blurry. Medical devices increasingly rely on computing and telecommunications. A 2010 analysis of patent data found that biomedical devices are strongly connected to computing and mobile telecommunications, while molecular bioengineering links tightly to multiple information technology fields.

The Smartphone as Convergence Made Manifest

No device illustrates convergence more dramatically than the smartphone.

In 1995, if you wanted to make a phone call, you used a telephone. To take a photograph, you used a camera. To check the time, you looked at a watch. To find your way in an unfamiliar city, you unfolded a paper map. To listen to music, you carried a Walkman or Discman. To play games, you brought a Game Boy. To read the news, you bought a newspaper. To look something up, you went to a library.

Each of these required purchasing a separate device, learning how to use it, maintaining it, and carrying it around. People specialized. Photography enthusiasts owned cameras. Gamers owned consoles. Businesspeople carried pagers and Rolodexes.

The smartphone collapsed all of this into one object. Not by accident, and not overnight, but through decades of digital convergence as each function was converted to software, miniaturized, and incorporated into an increasingly powerful handheld computer.

Today's smartphone contains accelerometers (for detecting motion and orientation), gyroscopes (for precise rotation sensing), magnetometers (for compass functions), barometers (for altitude and weather), proximity sensors, ambient light sensors, fingerprint readers, facial recognition cameras, infrared sensors, multiple cameras with different focal lengths, GPS receivers, Bluetooth radios, WiFi radios, cellular modems, near-field communication chips for contactless payments, and processors more powerful than supercomputers from the 1990s.

The implications ripple outward. Entire industries have been disrupted. The camera manufacturer Kodak, once a titan employing over 145,000 people, filed for bankruptcy in 2012. The GPS device maker Garmin had to reinvent itself for niche markets. Newspapers have lost most of their advertising revenue to digital platforms. The music industry was transformed first by piracy, then by streaming. Landline telephones are vanishing.

The Rise of Smart Television

Television followed a similar path, though more slowly.

For most of its history, television was a one-way broadcast medium. Signals traveled from transmitters to antennas, and viewers watched whatever the networks chose to air, at whatever time the networks chose to air it. The technology shaped behavior: families gathered at specific times for specific programs, and missing an episode meant missing it forever.

The internet offered something different: on-demand access to vast libraries of content. But internet video lived on computers, which lived in offices and dens, while televisions lived in living rooms. For years, these remained separate worlds.

Smart televisions, which became mainstream in the 2010s, merged them. Sometimes called connected television or hybrid television, smart television integrates internet access and web features directly into the television set or its set-top box. You can watch broadcast programming or switch to streaming services like Netflix. You can browse the web, check social media, make video calls.

This is distinct from earlier attempts to bring video to computers (web television) or to deliver television over internet infrastructure (Internet Protocol Television, or IPTV). Smart television keeps the television at the center of the living room but transforms it from a passive display into an interactive portal.

The business implications are enormous. Broadcast networks that once controlled what audiences could watch now compete with streaming services that offer unlimited choice. Advertising models built on captive audiences fall apart when viewers can skip commercials or switch to ad-free subscriptions. Cable television providers face "cord cutting" as consumers decide they no longer need hundred-channel bundles when they can subscribe directly to the handful of services they actually use.

Convergence and Social Movements

When communication technologies converge, the effects extend far beyond entertainment. The same tools that let you stream movies also let you organize political movements.

One of the most studied examples comes from Mexico's Zapatistas, an indigenous rights movement that emerged in the southern state of Chiapas in 1994. The timing was significant: the internet was just becoming accessible to ordinary users, and the Zapatistas became, in the words of sociologist Manuel Castells, "the first informational guerrilla movement."

The mainstream press had largely ignored or marginalized the Zapatista uprising. But the movement used the emerging internet to build a decentralized, global network of supporters. Analysis of web links—mapping connections between different websites—revealed that Zapatista-related causes bound together hundreds of nongovernmental organizations around the world.

The lesson has been applied repeatedly since: during the Arab Spring uprisings of 2011, during the Occupy Wall Street protests, during Hong Kong's pro-democracy demonstrations. Social media platforms built for sharing vacation photos become coordination tools for political action.

But there's an important caveat. As one analyst wrote, "Social media alone do not instigate revolutions." Online organizing must connect to offline action—protests in the streets, not just posts on screens. The technology enables, but doesn't replace, the hard work of building real-world movements.

This connects to the broader question of how technological convergence affects journalism and information flow. When anyone with a smartphone can broadcast live video to the world, the traditional gatekeeping function of professional journalists erodes. This creates both opportunities (more voices, harder to suppress information) and dangers (more misinformation, harder to verify truth). The convergence of media production and media distribution fundamentally changes who controls the narrative.

The Business of Convergence

For companies, convergence creates both threats and opportunities.

The threat is disruption. When your product's function can be absorbed into someone else's device, your market can evaporate overnight. Camera makers, GPS manufacturers, flashlight companies, watch brands, alarm clock producers, calculator firms—all have faced the existential question of what happens when their core product becomes a free app on a smartphone.

The opportunity is expansion. If you can deliver content across multiple platforms, your reach multiplies. Star Wars isn't just a film franchise—it's a book series, a television universe, video games, toys, theme park attractions, and merchandise of every conceivable type. The Matrix followed the same pattern. These brands demonstrate how convergence enables horizontal integration: spreading one intellectual property across multiple media and product categories.

But this leads to a criticism. Branding encourages expansion of existing concepts rather than creation of new ones. Why develop an original story when you can extend a proven franchise into yet another medium? Convergence may be concentrating creative energy around a shrinking number of mega-properties.

Media companies also face the challenge of rethinking their relationship with consumers. When audiences could only watch what broadcasters chose to air, the industry had enormous power. Now consumers can access virtually any content from anywhere, on their own schedule, often for free or near-free. The power balance has shifted, and companies must compete for attention in ways they never had to before.

The Promise and Peril of a Connected World

In the late 1980s, as CD-ROMs were becoming common, technologists predicted a digital revolution that would sweep away old media entirely. The future seemed clear: digital would replace analog, new would replace old, and a transformed media landscape would emerge.

Then came the dot-com crash of 2000. The bubble burst, fortunes evaporated, and the revolutionary talk seemed naive in retrospect. Perhaps the digital revolution had been oversold.

The truth, as usual, lay somewhere in between. Old media didn't disappear—newspapers still exist, radio still broadcasts, people still watch television. But none of these remained unchanged. Print newspapers migrated online. Radio stations stream on the internet. Television competes with YouTube and TikTok. The revolution happened, but it was messier and more gradual than the breathless predictions suggested.

One media scholar describes convergence as "the flow of content across multiple media platforms, the cooperation between multiple media industries, and the migratory behavior of media audiences who would go almost anywhere in search of the kinds of entertainment experiences they wanted." This captures something important: convergence isn't just about technology, it's about how people use technology. And people are unpredictable.

The scholar identifies five areas of convergence: technological (devices merging), economic (industries consolidating), social (communities forming around shared media), cultural (new forms of expression emerging), and global (worldwide distribution becoming frictionless). Each dimension interacts with the others in complex ways.

Divergence Within Convergence

Here's a puzzle: if everything is converging, why do we have more devices than ever?

Your home might contain a smartphone, a tablet, a laptop, a desktop computer, a smart television, a streaming stick, a gaming console, a smart speaker, a smartwatch, wireless earbuds, and a dozen other connected gadgets. If convergence means everything becoming one thing, shouldn't we have fewer devices, not more?

The answer is that convergence and divergence happen simultaneously at different levels. Media content is converging—the same shows appear on multiple platforms, the same franchises span multiple media. But hardware is diverging into specialized forms optimized for different contexts. You might watch a movie on your television at home, on your tablet during a flight, and on your phone while waiting in line. Same content, different devices, each optimized for its use case.

There's also the phenomenon of "media deconvergence"—the splintering of audiences into smaller and smaller niches. Instead of everyone watching the same three networks, people scatter across thousands of channels and services, each catering to specific interests. The technology that enables everything to be everywhere also enables everything to be somewhere specific. Mainstream and niche coexist.

Platform ecosystems add another layer of complexity. Apple devices work seamlessly with each other but imperfectly with Android. Amazon's ecosystem favors Amazon services. Google's products integrate tightly within Google's world. This creates what economists call "vendor lock-in"—once you've invested in one ecosystem, switching costs rise. So even as technologies converge in capability, they diverge into competing walled gardens.

The Ongoing Transformation

Convergence is not a destination but a process. There's no final state where all technologies have merged into one ultimate device, one supreme platform, one universal standard. Instead, convergence and divergence will continue to dance together, with technologies merging in some dimensions while specializing in others.

New waves of convergence are already visible. Internet Protocol-based services—VoIP for phone calls, streaming for video, smart home devices for household management—are replacing older dedicated technologies. Voice assistants are converging search, smart home control, communication, and entertainment into conversational interfaces. Augmented reality promises to overlay digital information onto the physical world, converging screens with the environment itself.

The implications reach into every corner of society. Education, healthcare, government, business, art, journalism—all are being transformed by digital convergence. The way we work, learn, communicate, create, and organize ourselves is shifting onto digital platforms that didn't exist a generation ago.

Whether this represents progress depends on what we value. Convergence brings convenience, accessibility, and new possibilities. It also brings disruption, surveillance, concentration of power, and the erosion of boundaries that once provided structure and protection. The technologies are neither good nor bad in themselves. What matters is how we shape them, and how they shape us in return.

The smartphone in your pocket contains more computing power than was available to entire nations a few decades ago. It connects you to more information than the largest libraries in history. It collapses distances and time zones. And it's still early days.

The convergence continues.
