Ever since ancient times, humanity has built problem solving tools.
In the beginning, those were crude weapons for hunting food. Gradually though, we began developing contraptions that weren’t aimed at killing other living beings.
As our ancestors transformed from hunter-gathering to agriculture societies their focus shifted. Humanity invented the written word. It began trading. It built cities and impressive feats of architecture. It needed devices capable of solving number-related problems.
The first proto computing tools were born. Simple contraptions, pebbles on sand.
Then a portable mechanical calculator, known as the abacus.
As mechanics and engineering thrived during the age of enlightenment, the first mechanical computers were born. Impressive apparatuses, able to perform surprisingly complex calculations.
The quantum shift took place after the invention of vacuum tubes and, later, transistors. This allowed the construction of electronic computers. Digital tools that changed humanity from the ground up. Today, we take for granted powerful computers we carry around in our pockets.
We often forget that it took thousands of years to reach this point and it all started with a simple abacus…
