The Oldest Computer Still Runs Today
Few tech facts are more astonishing than the existence of computers several decades older than most people realize. The oldest working computer isn’t some sleek device from the last century—it’s the Harwell Dekatron (also known as the WITCH), built in the early 1950s.
Reanimating History
Restored and now on display at The National Museum of Computing in the UK, the Harwell Dekatron holds the Guinness World Record as the world’s oldest working original digital computer. Its restoration took three years, piecing together thousands of wires, vacuum tubes, and relays—a stark contrast to today’s modern chips. This machine was designed to perform complex calculations for atomic energy research, running continuously for over a decade.
Why This Tech Fact Matters
Unlike smartphones that become obsolete in a few years, the Harwell Dekatron proves that good engineering can give technology an incredibly long life. It’s a tangible reminder of progress—a single computer the size of a room, now outsized by modern devices you carry in your pocket, yet still remarkably functional. This tech fact is a testament to both human ingenuity and the importance of preserving our digital history.

There Are More Devices Than People on Earth
One of the most staggering tech facts: as of 2023, there are more internet-connected devices than there are humans on the planet. The rapid expansion of IoT (Internet of Things) has fueled this device explosion.
Global Numbers That Shock
According to Statista, the total number of IoT devices worldwide exceeded 15 billion in 2023—far surpassing the global population of around 8 billion. This includes everything from smartphones and tablets to smart fridges, watches, and security sensors.
– A breakdown of the types of devices:
1. Smartphones
2. Wearable tech (like fitness trackers)
3. Smart home devices (thermostats, lights)
4. Industrial sensors and equipment
5. Connected vehicles
The Impact on Everyday Life
Tech facts like this reveal a future where smart devices will outnumber us even further. They’re integrated into our homes, workplaces, and public spaces, shaping how we live. Automation, remote monitoring, and personalized experiences are possible because our environments are blanketed in connected technology. But this also sparks questions about security and privacy.
Tech Facts: The Internet Weighs Less Than a Strawberry
Have you ever wondered if the internet has physical weight? One of the most bizarre tech facts is that scientists have calculated the approximate weight of all the electrons moving through the web—and it’s astoundingly light.
Weightless Bytes
In 2011, University of California scientist Dr. John Kubiatowicz estimated the total weight of the internet was around 50 grams—the equivalent of a single strawberry. This calculation is based on the mass of electrons involved in storing and transferring digital information through billions of devices. The paradox: even though the internet feels vast and unlimited, all its electronic bits barely tip the scales.
The Bigger Implications
Tech facts like this challenge our perception of digital infrastructure. While the internet seems intangible, it does depend on physical principles. It’s a mind-bending reminder that our virtual world is grounded in reality—even if its weight is hard to fathom.
Your DNA Could Store All the World’s Data
One of history’s mind-blowing tech facts: DNA—the molecule that carries genetic instructions—could theoretically store all the digital data ever created by humanity, with room to spare.
The Science Behind DNA Data Storage
Data scientists have discovered that one gram of DNA could hold 215 petabytes of information (roughly 47 million DVDs). Unlike hard drives, which have physical limitations, DNA’s enormous density allows for storing vast quantities of data in microscopic form.
Pioneering Experiments
In 2017, Harvard and Microsoft encoded an entire book, images, and video files into DNA strands and then decoded them with zero data loss. Research continues to reduce costs and improve speeds, however, large-scale DNA storage remains a future goal.
– Benefits of DNA storage:
– Unmatched density—entire data centers on a single chip
– Longevity—can last thousands of years if stored properly
– Low energy requirements
Does this mean we’ll soon ditch hard drives for genetic code? Not quite yet. But tech facts like this showcase possibilities that once seemed like science fiction. For more details on the breakthrough, read Nature’s coverage: https://www.nature.com/articles/nbt.4079
The First Webcam Watched a Coffee Pot
One of the quirkiest tech facts: the world’s very first webcam wasn’t built for security, business, or public broadcasts. It was focused entirely on a coffee pot in a Cambridge University computer lab.
The Birth of Remote Viewing
In 1991, scientists at Cambridge created the “Trojan Room Coffee Pot” webcam to monitor the coffee level from their desks—saving wasted trips for empty refills. This grayscale camera sent a live image to computers across the campus, eventually gaining internet fame as the world caught on.
From Java to Broadband
This humble experiment paved the way for today’s security cameras, video streaming, and remote office workflows. Tech facts like this highlight the playful nature of innovation; often, breakthrough technology begins with solving everyday problems.
– Fun takeaways from the first webcam:
– It ran for over a decade before being shut off in 2001
– Inspired millions of new use cases for webcams
– Demonstrates how creativity drives tech adoption
Tech Facts That Shape Our World
As we’ve explored, mind-blowing tech facts reveal the incredible ingenuity and sometimes whimsical roots behind the devices and concepts that power modern life. Many of today’s technologies have evolved from seemingly improbable or playful beginnings—from room-sized computers to revolutionary advances like DNA data storage.
It’s easy to take everyday tech for granted, but these tech facts encourage curiosity and deeper appreciation for the digital age. Whether it’s the strawberry-weight internet, device proliferation, or the transformative power of DNA, each fact tells a story of possibility.
