Certain modern technologies were designed with one goal in mind, only to be altered along the way. In other instances, they were originally intended for specific purposes but ended up serving entirely different functions.
This applies to a range of technologies we use today—from smartphones and USB drives to air conditioning systems, alarm sirens, and even blockchain technology, which supports digital currencies like Bitcoin. Most were not initially created for their current applications, and those that were, did not quite turn out as expected.
10. The USB Was Meant To Be Reversible
On average, it takes 2–3 attempts for a person to properly insert a USB into their computer. Ajay Bhatt, the creator of the USB, was aware of this issue. To solve it, he envisioned a flippable USB that could be inserted in either direction, similar to what we now see with USB Type-C.
At the time, Bhatt and his team didn't make the USB reversible because the technology was still in its infancy. Before the USB, computer and gadget manufacturers used various methods for transferring files between computers and external devices. Bhatt's goal was to create a universal solution through the USB.
However, the team was focused on minimizing prototype costs as they were uncertain whether their product would succeed in the market. Making the USB flippable would have required double the amount of wires and circuits, increasing production costs—something they wanted to avoid while dealing with an untested technology.
9. The iPhone Was Never Meant to Support Third-Party Apps
Third-party apps have become essential to any mobile operating system today. In fact, they are a major reason why a new mobile OS cannot easily emerge. Users looking for alternatives to Android and iOS often have to reconsider, as most mobile apps are developed specifically for these two platforms.
Surprisingly, we almost never had the App Store. When the first iPhone launched in 2007, Apple only permitted developers to create web apps, not native mobile apps. These web apps would automatically open in Apple's Safari browser. However, Apple reconsidered after developers expressed frustration over being limited to web apps rather than mobile apps.
iPhone users also began jailbreaking their devices, demanding greater functionality that could only be provided through mobile apps. Steve Jobs initially resisted this shift, even though many Apple executives believed it was inevitable. Jobs had concerns about the quality of third-party apps. Ultimately, he relented, and the App Store was launched in 2008.
8. Android Was Originally Designed For Cameras
Android would have never become a competitor to Apple if its creators had followed their initial vision of developing an operating system for digital cameras. Android was founded in 2003 by a four-person team aiming to create an OS that would allow photographers to transfer images from their cameras to PCs wirelessly or upload them directly to the cloud where they stored their photos.
The inventors stuck with this vision until they began seeking funding from investors in 2004. They soon realized that the digital camera market was on the decline, while smartphone sales were rising. As a result, they shifted their focus to developing their OS for smartphones. Android was later acquired by Google, which turned it into open-source software for smartphone manufacturers.
7. The Microphone Was Originally Meant to Be a Hearing Aid
The first microphone was invented by Emile Berliner in 1877. However, he wasn’t the only one working on microphone technology at the time. Alexander Graham Bell (the inventor of the telephone) was also developing a microphone and even produced a working prototype before Berliner.
However, Bell is not credited as the inventor of the microphone because his device was not practical. Interestingly, Bell’s goal for the microphone was different from that of other inventors. While they aimed to amplify sound, Bell was focused on creating a hearing aid to help people with hearing impairments hear more clearly.
Bell came up with the idea for the microphone after visiting his mother, who had hearing difficulties. He had also worked with others who had hearing impairments. Bell had been involved with the hearing-impaired community from a young age, as his mother was partially deaf.
His father, Melville Bell, invented a writing system known as Visible Speech for the deaf. Alexander Graham Bell also worked as a teacher at Pemberton Avenue School for the Deaf in Boston. He later married one of his students from the school, Mabel Hubbard.
6. Blockchain Was Initially Created To Time-Stamp Documents
Few people realize that the blockchain—the foundation of cryptocurrencies like Bitcoin—was originally invented by Stuart Haber and W. Scott Stornetta in 1991. They created blockchain as a method for securely time-stamping documents. However, the mysterious Satoshi Nakamoto found a different application for it when he developed Bitcoin in the late 2000s.
In their original paper titled “How to time-stamp a digital document,” Haber and Stornetta explained that the blockchain would prevent users from being able to “back-date or forward-date [a] document, even with the collusion of a time-stamping service.” They also emphasized that it would “maintain complete privacy of the documents themselves, and require no record-keeping by the time-stamping service.”
This is essentially how cryptocurrencies like Bitcoin function. While the identities of Bitcoin owners and their transactions remain private, the transaction itself is visible to others, serving as a timestamp. Additionally, Bitcoins are nearly impossible to counterfeit. However, Haber and Stornetta originally envisioned blockchain as a way to prove that a document existed at a specific time, which could be especially useful in legal disputes.
5. The Siren Was Originally Designed As a Musical Instrument
Today, sirens are associated with warnings of impending danger. But originally, they were not meant to signal danger at all. The modern siren was invented by John Robison, a Scotsman, in 1799. He saw it as a musical instrument, despite the fact that it produced the same sound as today's warning sirens.
In 1819, Frenchman Cagniard de la Tour also developed a siren. His primary interest was using it for scientific research. Tour employed the device to study the speed of a mosquito's wing, the velocity of sound underwater, and the frequency of musical notes. However, he did note that the siren could also be used as a signaling device on ships.
These devices were only repurposed as warning signals during World War II when the British government used them to warn citizens about German air raids. The United States also adopted their use for tornado alerts after a catastrophic tornado struck Tinker Air Force Base in Oklahoma in 1948, causing widespread destruction and fatalities. Instead of developing a new tornado warning system, the US government relied on the proven siren technology.
Interestingly, the US never issued tornado warnings before 1948, despite having considered the idea earlier. In 1887, authorities decided against the warnings, fearing they would cause more chaos than they prevented. The siren technology was later expanded to warn of nuclear threats after President Harry Truman enacted the Civil Defense Act during the Cold War in 1950.
4. The Ice Machine Was Created to Cool Hospital Patients
The ice machine was a byproduct of the refrigerator, a device that had been in development for centuries until William Cullen created the first practical mechanical refrigerator in the 1720s. Many inventors later made improvements to his design, including Oliver Evans, who, in 1805, introduced a version that used vapor instead of liquid for cooling.
In 1842, US physician John Gorrie enhanced Cullen’s refrigerator design to create an ice machine. Gorrie used this machine to produce ice, which helped reduce the body temperatures of yellow fever patients at the hospital where he worked. He was granted a patent for his invention in 1851.
3. The First Air Conditioner Was Designed To Cool A Printing Plant
Willis Carrier is credited with inventing the first practical air conditioner in 1902. Like the ice machine, the air conditioner evolved from the refrigerator. The inventors of the air conditioner were actually focused on improving refrigerators when they discovered the cooling properties that would lead to air conditioning.
As mentioned earlier, Gorrie created the ice machine and later improved it to develop a cooling system similar to an air conditioner, although based on refrigeration principles. However, he is not recognized as the inventor of the air conditioner because his version lacked practicality.
In 1902, executives from Sackett-Wilhelms Lithographing and Publishing Company in Brooklyn, New York, asked Carrier to design a cooling system for their factory. The humid conditions in the factory were damaging the colors used in their printing process. Carrier's solution is regarded as the first air conditioner.
2. The Steam Engine Was Created To Pump Water Out Of Coal Mines
The steam engine played a crucial role in the first industrial revolution. Although it may seem outdated now, it powered various machines, mills, factories, airships, trains, and boats centuries ago. However, its initial purpose was to pump water out of coal mines.
The steam engine's development spanned centuries, but like robots, early versions were impractical. The first steam machine, technically not an engine, was created by Jeronimo de Ayanz in 1606. He designed it to pump water out of coal mines.
Ayanz's machine lacked efficiency. In 1698, Thomas Savery improved upon it, creating what is regarded as the first true steam engine. Like Ayanz, Savery's invention was designed to pump water out of coal mines, though it was still flawed. It could only remove water from shallow mines and was prone to dangerous explosions.
In 1711, Thomas Newcomen made advancements to the steam engine, enabling it to pump water from deeper mines. Although it functioned, it was still inefficient. Then, in 1765, James Watt refined Newcomen's engine to create a far more efficient version. Watt's improved steam engine soon became integral in powering factories and eventually vehicles.
1. The First Programmable Robot Was Designed For Die-Casting
The concept of robots has been around for centuries. However, the first true digital and programmable robot was created by George Devol in 1954. He later teamed up with Joseph Engelberger to establish the very first robotics company.
Named Unimate, this robot was a single-arm industrial machine, resembling those used in car manufacturing today. Interestingly, Unimate was not part of the vehicle assembly process; it was specifically designed to handle the perilous task of die-casting, which involves pouring molten metal into a preset mold.
In 1959, General Motors installed the first Unimate robot at their die-casting plant in New Jersey. Its success led other manufacturers and industries to adopt the Unimate for similar tasks. Within a few years, other one-armed robots were designed for a range of functions, including the complete assembly of vehicles from the ground up.
