Wikipedia’s Final Page

A few days ago I ended up at a birthday party I had absolutely no business attending. Technically, it was the birthday of a friend’s friend’s kid. In other words, I was there like someone who shows up at the wrong place but sticks around out of sheer politeness. The backyard was packed with eight-year-olds obsessed with dinosaurs and grape juice. And me, frozen next to the chips, like someone had hit pause on my body.

At one point, one of the kids walked up to his mom (my friend’s girlfriend, the only person there who even acknowledged my existence) and asked about some unpronounceable dinosaur. She had no clue, of course, so she gave the standard adult answer: “We’ll look it up on Wikipedia later.” The kid looked at her as if she’d said they were going to consult the Dead Sea Scrolls. “What’s Wikipedia?” he asked.

She did her best—told him it was a place where pretty much everything was written down. And without missing a beat, the kid fired back with another question: “How many pages does it have?”

She answered automatically: “A lot.”

But that question stuck with me. Because we know that Wikipedia isn’t measured in pages. Or at least we think it isn’t. We know it doesn’t have a final page, that it’s constantly expanding, like some kind of digital universe. But… will it be like that forever?

What if it’s not?

What if, one random Tuesday in the future, someone uploads the final article? Maybe it’s about a micro-species of fungus from the Bolivian highlands or a forgotten funeral rite from two long-extinct tribes. With that click, Wikipedia is complete. And then what?

Do we just keep updating what’s already there? Does Wikipedia turn into an eternal newsfeed in disguise, dressed up as an encyclopedia, full of past-tense verbs and footnotes?

But the most unsettling question is: is it possible that we could, at some point, have said everything there is to say?

The idea left a strange noise humming in the background—like an existential buzz I couldn’t shake. Not because we’re running out of information—the universe is packed with secrets we haven’t even begun to suspect—but maybe because we’re entering a phase where the real challenge isn’t discovering what’s new, but making the invisible visible. As if we’re shifting from explorers to curators. From pioneers to librarians.

But let’s go back:

What if we’ve already written it all? Not literally, of course. There are millions of physical phenomena we don’t understand, thousands of undocumented languages, whole civilizations buried under layers of earth and amnesia. But there’s something deeper behind that question. It’s not just about content—it’s about mental architecture. What if we’ve simply exhausted this particular model of knowledge?

I say this with the kind of nostalgia only someone who once used the Britannica as a stool to reach the top-shelf glasses could muster. That collection of shiny spines taking up an entire bookshelf—half status symbol, half cultural promise—was, for decades, the gold standard of bound human knowledge. Throughout the 20th century, Britannica was the peak: sold by mail order, paid in installments, as valuable as a typewriter or a washing machine. It was printed, updated, handed down. Until one day, it wasn’t. In 2010, the inevitable rise of the Internet—and its deadliest enemy, the instant obsolescence of paper—marked the end of an era. The most respected encyclopedia in the world didn’t fall from grace—it simply got outrun. Since then, knowledge stopped being measured in volumes and started floating. And so, Wikipedia was born.

Wikipedia was born as a promise of accumulation. A sort of Borgesian project: to gather all the world’s information, organize it, footnote it, and make it available to anyone with a screen. But like all accumulation-based models, it has a limit. Like fractals—those figures that keep generating shapes within shapes, endlessly complex but always stuck within the same perimeter.

What if we’re trapped inside a knowledge fractal?

In geometry, a fractal is a shape that repeats at different scales, creating infinite complexity within finite boundaries.

What if human knowledge is exactly that?

This anxiety isn’t new. In ancient times, it was said the Pillars of Hercules—located at the edge of the Strait of Gibraltar—bore the inscription Ne plus ultra, “nothing further beyond,” as a warning to sailors not to venture past the limits of the known world. Immanuel Kant, in Critique of Pure Reason (1781), used that very metaphor to describe the boundaries of human knowledge, suggesting that reason must sail only as far as the coastline of experience allows—without drifting into uncharted waters.

A friend of mine—who studied psychology but never practiced—once told me something that stuck. He said there was a study from the 1950s—by a guy named George Miller, I think—that said the human brain can only process between five and nine things at once. After that, we start mixing up names, ideas, keys, and even what day it is. Ever since he told me that, every time I forget something, I just assume I’ve hit my daily limit of seven.

When you’re twenty, you feel invincible—you learn fast, improvise, change your mind mid-sentence. At fifty, it’s not so easy. But instead, you start recognizing patterns. You can see how a conversation will end before it even begins. You can smell whether a random fact is legit or just dressed-up nonsense. It’s not that we stop learning—it’s that we learn differently. Less spark, more map. Maybe that’s why we keep writing Wikipedia: not to uncover the new, but to make sense of what we already half-understand.

Even math, which we tend to imagine as the last refuge of certainty, has cracks of its own. There was this guy, Kurt Gödel—who looks like the type of professor who never takes a vacation—who showed that inside any logical system, there are truths that can’t be proven or disproven from within. As if knowledge had locked rooms, and the keys were hidden in a house next door. Which is wild—because even in the land of numbers, we can’t count on being able to prove everything.

And then there’s something more basic. Our understanding doesn’t depend only on how much we read, but on who we are—what’s in our heads, what we see, what we speak. We think in words. If we don’t have a word for something, the thought itself slips away—like trying to grab water with your hands. George Orwell made this brutally clear in 1984, when he invented Newspeak: a language so reduced, it made critical thought impossible. If you can’t name injustice, how do you protest it?

To get a sense of what kind of beast Wikipedia has become, just look at the numbers. As of April 9, 2025, the English version alone had nearly seven million articles. Seven million. Over 4.8 billion words, spread across more than 62 million pages. An average of 694 words per article—each one like a miniature chronicle of a parallel universe. And here’s the wild part: the articles only make up about 11% of the site. The rest? Infrastructure. Background. The invisible machinery. Like a library that doesn’t just hold books but also stores the shelves, the aisles, and every footprint of every librarian.

Now imagine trying to print it all. If each volume held 1,333,333 words, you’d need about 3,630 books to contain the current collection. And that’s just the articles—not the images, the edits, or the arguments in the talk pages.

And yet, Wikipedia isn’t finished. Not even close. It’s still alive, still in motion—like a city where something is always under construction. But something has changed. We don’t write new articles with the same urgency as before. Back in 2010, 372,000 new entries were created. In 2022, only 164,000. It’s as if, after running a 20-year marathon, the community decided it was time to tidy up, edit, make things prettier. Less exploration, more gardening. Maybe we’re not done writing—maybe we’re just learning to reread.

But here’s the thing: the people who make Wikipedia? They’re in on the cosmic joke. They know that someday, somewhere, someone might write the final article. That’s why they created—tongue firmly in cheek—a “Last Topic Pool,” where anyone can bet on what the last entry will be. A newly discovered star? A forgotten algorithm? The perfect alfajor recipe? It’s a game, sure—but also a mirror. Because inside that joke lives a real question: does human knowledge have a final page?

Maybe we’re not close to writing the last page of Wikipedia.

But let’s be honest—we’re no longer alone at the table. Just like the Encyclopædia Britannica—once the sacred oracle of anyone with a bookshelf behind a glass door—was swept aside by Wikipedia, there’s a new odd guest sitting quietly with us now: language models.

Intelligences that don’t just answer questions—they invent them. That don’t need articles or references, or even to be right. They just talk. And sometimes, with a confidence that feels uncanny, they get it right. Other times, they go off script and lie beautifully. Like a version of Wikipedia with no footnotes. Or worse—with imaginary footnotes that sound perfect.

Wikipedia has its flaws—but it also has footnotes. It has a community. It has edit history. It has memory.

So no, maybe we’re not ready to close the book just yet.

But we might already be in that strange chapter where you start to wonder whether the next book will be read with your eyes, your fingers, or your voice. Maybe the next encyclopedia won’t have pages. Or authors. Or margins. Maybe it won’t even be read.

But that, for now, we don’t know.

The only thing we do know—with no debate, no citation needed—is this:

The last Wikipedia entry, the one that explains it all… still hasn’t been written.
