A colleague once bet me that email came after the internet. He lost. That kind of confident wrongness is exactly why fun facts about technology are worth knowing, not as pub-quiz ammunition, but because the real history of how things got built is genuinely stranger than the clean version most of us learned.

Almost nothing in modern tech arrived through deliberate, elegant design. Most of it stumbled into existence because someone was solving a different problem, made an error, or got bored making playing cards. Here are the cases that stick with me most.

Accidents That Shaped Modern Tech

The first computer bug was an actual insect. On September 9, 1947, engineers on the Harvard Mark II found a moth trapped in relay number 70. Grace Hopper’s team taped it into the logbook with the note “first actual case of bug being found.” The word “bug” for a software error existed before that (Edison used it), but this moment made the metaphor literal. The logbook still sits at the Smithsonian.

Email predates the internet by a good stretch. Ray Tomlinson sent the first networked email in 1971 over ARPANET, a military research network with nothing in common with what we use now. He picked the @ symbol because it wasn’t used in names and seemed unlikely to cause confusion. He later said he couldn’t remember what the first message said, which is either humble or just honest.

And then there’s the QWERTY keyboard. The standard story is that it was designed to slow typists down so mechanical keys wouldn’t jam, and that’s mostly right, though some historians push back on the finer details. What nobody disputes: the layout was optimised for telegraph operators decoding Morse code, not for human typing speed. We’ve had better alternatives for decades (Dvorak, Colemak) and almost nobody uses them. Inertia, it turns out, is a serious force.

Inventions Built for Different Purposes

Nintendo was founded in 1889. Not as a game company — as a playing-card manufacturer in Kyoto. Fusajiro Yamauchi made handcrafted hanafuda cards, and the company spent nearly 80 years in that business before experimenting with toys in the 1960s and eventually video games in the 1970s. The original Game Boy came out a full century after the company launched. Most people’s mental timeline starts with Donkey Kong, which misses almost everything interesting.

The first website is still live. Tim Berners-Lee launched it at CERN on August 6, 1991, and you can visit info.cern.ch right now. It explains what the World Wide Web is, which is a slightly surreal experience given that you’re reading it on the thing it’s describing. CERN restored the original URL in 2013 so the historical record wouldn’t break. Worth a look, if only to see how sparse it is.

GPS was built for the US military and stayed restricted for civilian use until 2000, when President Clinton ordered Selective Availability turned off. Before that, the signal available to civilians was deliberately degraded. The satellites cost roughly $18,000 per unit to build and launch, the full constellation runs into billions, and the ground control system needs constant correction to hold accuracy to around 30 centimetres. Your phone gets that precision for free, riding infrastructure that cost more than most countries’ defence budgets.

Numbers That Reframe Everyday Devices

The data statistic I find hardest to picture: over 90% of all data in human history was created in roughly the last two years. That figure gets updated annually and stays roughly true, because the rate keeps accelerating. Photos, sensor logs, messages, video — it compounds fast. The entire written output of humanity up to around 2000 is a rounding error compared to what we generate on a slow Tuesday now.

The first commercial hard drive, the IBM 350, shipped in 1956. Five megabytes, about a ton. A modern microSD card the size of your thumbnail holds a terabyte, which is 200,000 times more. Price per gigabyte has dropped from roughly $10,000 in the 1980s to fractions of a cent today. That compression of cost and size happened faster than almost any other technology in history, and it’s part of why the data explosion above is even possible.

The fun facts about technology that land hardest aren’t about alien-seeming future tech. They’re about ordinary stuff right in front of us: keyboards designed for telegraphs, a navigation system funded by Cold War anxiety, a gaming giant that spent its first century making card games. The weirdness is already here.

FAQs

What is the most surprising fact about technology?

Most people find the email-before-internet timeline genuinely shocking. Ray Tomlinson sent networked email in 1971, nearly two decades before the public internet existed.

Who invented email and when?

Ray Tomlinson invented networked email in 1971 using ARPANET. He also chose the @ symbol as the separator between username and host machine.

What was the first computer bug?

A real moth trapped in the Harvard Mark II relay in 1947. Grace Hopper’s team taped it into the logbook; that page is now at the Smithsonian.
