The USB was supposed to be reversible -

The original plan was to make a reversible USB, just like the USB-Type C, which features a symmetrical connection that can be used in any position.

The USB was supposed to be reversible -

To make his prototype flippable, Bhatt would have had to create a much more complex and expensive product. This was an unproven technology and the financial risk was too high.

The iPhone was never meant to support third-party apps -

When Apple’s innovative product was launched in 2007 there was no such thing as an App Store. Back then, Apple developers would only create web apps and not mobile apps.

Android was originally invented for cameras -

When the company started to seek funding from investors, the digital camera market was declining and the smartphone market was booming, so they changed direction. Android was later acquired by Google and the rest is tech history.

Blockchain was just a way to timestamp documents -

Blockchain is one of the greatest technological advancements of recent history. Stuart Haber and W. Scott Stornetta’s 1991 paper indicated that it would be used to “back-date or to forward-date [a] document, even with the collusion of a time-stamping service.”

The paper also said that blockchain would “maintain complete privacy of the documents themselves, and require no record-keeping by the time-stamping service.”

In the late 2000s, Satoshi Nakamoto created Bitcoin using this new technology. The world of cryptocurrency was born, where timestamped, incorruptible transactions became a reality.

The microphone was intended to be used as a hearing aid -

Emile Berliner (pictured) invented the microphone in 1877. But it turns out, he wasn’t the only one working on a microphone.

Alexander Graham Bell (who invented the telephone) was also working on one, and he even managed to make a working prototype before Berliner.

The microphone was intended to be used as a hearing aid -

While Berliner saw the microphone simply as a way to amplify the sound, Bell was more interested in its application as a hearing aid.

The microphone was intended to be used as a hearing aid -

Bell’s mother was partially deaf, so a solution for hearing-impaired people was a matter close to his heart. The microphone eventually became part of the first Bell telephones.

The ice machine was invented to cool hospital patients -

In 1842, American doctor John Gorrie created an ice machine, which he then used to lower the body temperatures of yellow fever patients at the hospital where worked at. Gorrie secured a patent for his invention in 1851.

The first robot was programmed for die-casting -

The first programmable robot dates back to 1954. George Devol's invention was a one-handed industrial robot called Unimate.

The first robot was programmed for die-casting -

Unimate’s job was simple, yet dangerous. This robot was programmed for die-casting (pouring hot metal into a mold).

The first robot was programmed for die-casting -

Unimate made General Motors' die-casting plant in New Jersey its home. Soon after, the robot was working with other automakers and businesses. Other one-arm robots were then developed to perform a wide array of tasks, many of which were pretty sophisticated.

The steam engine was supposed to pump water out of coal mines -

The invention of the steam engine was a game changer. There have been many prototypes throughout history, ever since Hero's aeolipile.

The steam engine was supposed to pump water out of coal mines -

The original objective of the new machine was to pump water out of coal mines. In 1698, Thomas Savery built up other machines and created what is considered the first proper steam engine.

Thomas Newcomen then made an updated version of it in 1711. Later, in 1765, James Watt made yet another improvement to the steam engine and it became good enough not only to pump water out of coal mines but power factories and vehicles.

Air conditioning was invented to cool a printing plant -

The first air conditioner was created by Willis Carrier in 1902. Similar to the ice machine, the AC was also a spin-off of the refrigerator.
