Humans are obsessed with leaving a mark. We carve names into trees, build stone monuments, and lately, we dump everything into the "cloud." But here is the cold, hard truth: almost nothing you did today will exist in a format anyone can read in a century, let alone when we start logging 10 000 years into the future. It's a digital dark age. It’s coming for your photos, your bank records, and the very blueprints of our civilization.
Think about a floppy disk from 1995. Can you read it? Probably not without a specialized trip to a museum or a very dusty basement. Now, multiply that problem by five hundred.
The concept of logging 10 000 years into the future isn't just some sci-fi trope about robots and flying cars; it is a rigorous engineering challenge being tackled by people like Stewart Brand, Danny Hillis, and the Long Now Foundation. They are building a clock inside a mountain in West Texas designed to tick for ten millennia. But the clock is the easy part. The hard part? Keeping the record of its existence—and our own—alive.

The Bit Rot Problem and the Death of Digital Memory
We’ve tricked ourselves into thinking digital is permanent. It’s actually the most fragile medium we’ve ever invented. Stone lasts. Vellum lasts. Sulfide-based paper lasts a few hundred years if you’re lucky. But a hard drive? You’re looking at a five-to-ten-year lifespan before the magnetic charge dissipates. This is "bit rot."
When we talk about logging 10 000 years into the future, we aren't just fighting physical decay. We are fighting "software obsolescence." Imagine finding a pristine data hoard in the year 12,026. It’s a series of glass plates encoded with high-density laser etching. Incredible. But what’s the file format? If it’s a .jpg or a .pdf, and the instructions on how to build a machine to interpret those bits are lost, that data is just noise. It's electronic garbage.
Vint Cerf, often called one of the fathers of the internet, has been sounding the alarm on this for years. He argues that we are heading toward a "digital black hole." We are creating more information than any generation in history, yet we are at the highest risk of being completely forgotten. Honestly, a monk in the 12th century writing on calfskin had a better long-term storage strategy than a Google engineer does today.
The Rosetta Project and the 1,000-Language Disc
To solve this, the Long Now Foundation created the Rosetta Disk. It’s a three-inch nickel disk. They didn't put digital code on it. Instead, they used "analog" micro-etching. You don't need a computer to read it; you just need a microscope.
It contains 13,000 pages of information on over 1,500 human languages. Why? Because language is the first thing that breaks over 10,000 years. If you can’t read the instructions, you can’t use the logs.
The Nuclear Waste Problem: A Warning That Lasts
One of the most practical applications of logging 10 000 years into the future is actually buried underground. Literally. The Waste Isolation Pilot Plant (WIPP) in New Mexico is a graveyard for transuranic radioactive waste. This stuff stays deadly for a long, long time.
The US government had to figure out how to tell someone 10,000 years from now: "Don't dig here."
Think about how much English has changed since Beowulf. That was only 1,000 years ago. In 10,000 years, English will be as dead as Proto-Indo-European is to us. So, the experts—semioticians, linguists, and architects—came up with "Nuclear Priesthoods" and "Ray Cats."
- The Spikes: One proposal involved building massive, jagged "Landscape of Thorns" out of concrete to trigger a primal "stay away" response.
- The Changing Language: They realized words fail, so they looked at biological markers.
- The Records: They created "Level II" archives—logs designed to be passed down and rewritten every few generations to keep the language current.
This is the "active" version of logging 10 000 years into the future. You don't just write a file and hope. You create a culture of curation.
How We Are Actually Building the 10,000-Year Log
So, if hard drives are useless, what are we actually using to record our era for the deep future? There are a few competing technologies that actually have a shot.
5D Optical Data Storage (The Superman Memory Crystal)
Researchers at the University of Southampton have developed a way to write data into nanostructured glass using ultra-fast laser pulses. They claim it can store 360 terabytes of data for billions of years. It’s stable up to 1,000 degrees Celsius. This is the gold standard for logging 10 000 years into the future. It doesn't need power. It doesn't rot. It just sits there.
DNA Data Storage
Biology has been logging information for billions of years. We can now encode binary data into synthetic DNA strands. Harvard's George Church has successfully encoded his own book into DNA. While DNA is fragile if left in the sun, if you freeze it or keep it in a cool, dry salt mine, it can last tens of thousands of years. The density is insane: you could theoretically store all the world's data in a few grams of DNA.
The Arctic World Archive
Located on the same island as the Global Seed Vault in Svalbard, Norway, this archive uses "analog film." A company called Piql takes digital data and turns it into high-density QR-like codes on photosensitive film. It’s stored in a decommissioned coal mine in the permafrost. No electricity needed. Just a vault and a very long wait.
The Ethics of Deciding What Stays
Who gets to choose what is included in a 10,000-year log? Most of our current logging is accidental. It’s metadata, server logs, and social media posts. If we are being intentional, what do we save?
Do we save the Wikipedia archives? (The Long Now already has). Do we save our genomic data? Or do we save the "boring" stuff—tax codes, property deeds, and weather patterns?
The Svalbard archive holds things like the Vatican Library's manuscripts and Brazil’s constitution. But it also holds open-source code from GitHub. If society collapses and restarts, those code libraries are the "fire" they'll need to jumpstart a digital age.
Why Logging 10 000 years into the future is Kinda Terrifying
There is a concept called the "Lindy Effect." It suggests that the longer something has survived, the longer it is likely to survive. A book that has been in print for 500 years will likely be in print for another 500. A tweet that has been around for 5 minutes? It's probably gone in another 5.
When we try to bypass the Lindy Effect by forcing a log to last 10,000 years, we are playing God with history. We are deciding what the future will know about us.
But there’s a catch. 10,000 years is about the length of all human civilization since the Neolithic Revolution. In that time, stars shift. The Earth’s wobble changes. The "North Star" won't even be Polaris anymore; it'll be Vega (eventually).
If we log our location using current celestial coordinates, the people logging 10 000 years into the future might think we lived on a different planet.
Actionable Steps for Long-Term Data Preservation
You probably aren't building a clock in a mountain, but you likely have photos or documents you want to last at least 100 years. Here is how you do it without relying on a cloud provider that might go bankrupt in 2035.
- The 3-2-1 Rule (Modified): Three copies, two different media types (e.g., M-Disc and Paper), and one copy stored in a different geographic location.
- Use M-Discs: Standard DVDs rot. M-Discs use a rock-like data layer that is physically etched. They are rated for 1,000 years. It’s the closest thing a consumer can get to a 10,000-year log.
- Print Your Best Photos: Use acid-free paper and pigment-based inks. A physical photo in a box is more likely to be seen by your great-great-grandchildren than a file on a dead iPhone 15.
- Save the "Read Me": If you save digital files, include a text file (ASCII format) that explains what the files are and what software is needed to open them.
- Avoid Proprietary Formats: Never use a file format owned by a single company if you can avoid it. Use .txt, .csv, and .tiff.
The Reality of the Deep Future
Ultimately, logging 10 000 years into the future is an act of hope. It’s a belief that there will be someone there to read it.
The Long Now’s clock is a "monument to time." It’s meant to change how we think. If we start thinking in 10,000-year increments instead of quarterly earnings or 24-hour news cycles, we might actually make decisions that ensure there is someone around to read the logs.
We are currently the most documented society in history, yet we are the most likely to leave behind a silent, unreadable void. To fix that, we have to stop thinking about "storing" data and start thinking about "transmitting" it.
Final Practical Insight
If you want to ensure a piece of information survives 10,000 years, don't put it on a server. Etch it into a high-purity sapphire disk or a piece of black granite. High-tech is for today; low-tech is for eternity.

To start your own long-term preservation, begin by migrating your most important digital assets to a "cold storage" medium like an M-Disc or archival-grade paper records. Audit your digital "legacy" settings on platforms like Google or Apple to ensure your data is accessible to heirs, then consider contributing to public archives like the Internet Archive (Wayback Machine) to ensure your public contributions are part of the larger human log.
