The Era of the Chairman Has Begun

Prologue: A 60-Year-Old Promise Breaks

In 1963, after Douglas Engelbart invented the mouse, an unspoken pact existed between humans and computers.

"If humans learn the language of machines, machines will help humans with their work."

We learned CLI. We mastered GUI. We internalized touch. We trained ourselves on voice commands. Icons, menus, buttons — all of these were ultimately acts of humans taking half a step toward the machine.

But now, that promise is breaking. The machine is walking toward the human first. It interprets human intent, and machines execute everything among themselves. This is not "things getting more convenient." It is the quiet but violent extinction of the interface layer itself — the very medium losing its reason to exist.

And when the interface disappears, every castle built upon it crumbles together.

Chapter 1: The Economy of the Eye Fades

For the past 20 years, the digital economy ran on a single, simple formula. Gather the user's gaze and sell it to advertisers. Google did it. Meta did it. Naver and Kakao did it.

Dwell time, DAU, retention, click-through rate — these glamorous metrics were ultimately variations on a single question: "How long and how much of human attention have we captured?"

But the moment an agent handles execution on behalf of the user, the premise of this formula collapses. The eyes to show things to simply vanish.

Agents don't look at ads. Even if they could, they'd be optimized to ignore them. We're transitioning from a world that spread ten options before a human and made them choose, to a world where an agent picks the single best option and executes immediately. The era of screen share ends. The era of execution share begins.

What this means is not merely that the format of advertising changes. It means the $600 billion global digital advertising market is losing its very reason to exist. It's not the format of advertising that's shaking — it's the premise of advertising as an act.

Chapter 2: The War for the New Throne Begins

Here, an uncomfortable question emerges. If an agent selects the single optimal option for a given context, who designs the criteria for that selection?

This is precisely where a new form of power is born.

In the search era, Google reigned as the one who decided "what to show at the top." In the agent era, that power shifts to model makers and agent framework architects.

We can call this AEO — Agent Engine Optimization. Embedding your service into the agent's decision-making algorithm so that it gets chosen. This is the new battlefield of marketing, replacing SEO.

But this structure is far more opaque and concentrated than the SEO era. In the SEO era, at least ten search results were laid out side by side on the screen. Users had choices. But an agent picks only one. The form of monopoly is changing. From platform monopoly to agent model monopoly. From visible monopoly to invisible monopoly.

Chapter 3: Tear Down the Walls, or Be Forgotten Within Them

Here lies the most pragmatic fear of existing businesses. And this is an exact replay of Clayton Christensen's Innovator's Dilemma.

App-based services have walls built over years. User databases, payment information, behavioral data — this is lock-in, this is the moat. Until now, trapping users inside this Walled Garden was the core of competitive strategy.

But if you open the gates via MCP and API, agents freely roam across multiple services. The moat fills in. On the other hand, if you don't open up? Agents can't access you at all. Your very existence evaporates.

Open up and the moat collapses. Stay closed and you vanish from the world. This is the dilemma.

And ultimately, economic gravity decides the answer. The cost of marketing to agents is structurally cheaper than marketing to human users. Few companies can defy this gravity. They will inevitably be pulled toward openness.

However, amid this transition, small companies born API-first from day one hold a structural advantage — and that is the truly terrifying story for the existing giants.

Chapter 4: The Light and Shadow of "Everyone Becomes a Chairman"

Everyone becomes a chairman. A delightful phrase. An individual commands a legion of agents and single-handedly accomplishes what once required an entire organization. A one-person company rivals the productivity of a hundred-person company. This is undeniably a narrative of democratization.

But look into the shadows of this metaphor, and a different story emerges.

To become a chairman, there is a prerequisite: the ability to judge what to command the agents to do — that is, strategic decision-making capability.

Until now, "the ability to execute well" held value in the job market. Writing a great proposal, coding fast, refining a design with precision. But the moment agents replace execution, only "the ability to decide what to do" retains value.

Not every human is a brilliant strategist. This structure is unprecedented liberation for the few, but for the many, it becomes the experience of their value proposition quietly evaporating. The gap between the cognitive upper class and the cognitive lower class widens to extremes.

Behind the optimism of "everyone becomes a chairman" hides the existential crisis of the majority who cannot become one.

Chapter 5: A Planet Where One Day Becomes One Month

Consider the decision-making cycles of existing corporations — quarterly strategy reviews, annual roadmaps, semi-annual budget planning — all of these are completely out of sync with the speed of change.

The judgment that "adoption rates are still low" is based on a linear diffusion model. But agent adoption combines network effects with a zero-marginal-cost structure, meaning it is likely to spread non-linearly — that is, exponentially.

The moment a killer agent comes pre-installed on Android just once, the transition where "installing an app to use a service" becomes a relic of a bygone era takes only months.

A company that says it will review things quarterly may open its eyes next quarter to find the outside world has already aged years. Like Cooper returning from Miller's planet.

Epilogue: The Real Question

Compress all these currents into a single sentence:

The value capture point of the digital economy is shifting from "the user's eyes" to "the agent's execution," and this transition simultaneously restructures interfaces, advertising, monetization, platform power, and labor structures.

But at the deepest floor of all these changes lies one question.

In a world where agents handle all execution, where exactly does uniquely human value reside?

This wears the clothing of a technology forecast, but its essence is an existential question.

And perhaps, only those who hold the answer to this question can become chairmen in the truest sense.
