An invention that has survived for thousands of years

The need to protect one’s valuables is as old as humanity itself. People have always felt the need to hide their possessions from thieves, leaving them in hard-to-reach places such as rocky crevices or caves. Burying them or creating special hiding spots, such as in the floor or ceiling of houses, was a good idea—though not as simple and convenient as locking valuables away with a key.

The Egyptians came up with this idea around 2000 BCE, creating special locking mechanisms that could only be opened with the correct key. Though this method is ancient and simple, it has proven its timelessness. This solution has remained with us to this day, and although it has been refined over the years, its fundamental principle has stayed the same.

But one thing makes me wonder. Today, we have more than just this traditional form of security—a padlock and a key. We also have a range of modern alternatives, such as combination locks or even biometric locks. And yet, it seems that most of us still prefer the old method over technological innovations. Why is that?

Is it a matter of cost? Cipher and biometric solutions are certainly more expensive than a traditional key and lock. Or maybe, in this aspect at least, we want to feel independent of technology, which is becoming an ever-greater part of our lives?

In my opinion, the secret lies in simplicity and reliability—there’s a reason why this invention has survived for thousands of years. Keys and locks don’t require any power supply, and they are difficult to break. This shows that despite continuous technological progress, sometimes the simplest and easiest solutions turn out to be the most durable.

I wonder—will keys and locks ever be entirely replaced by advanced technological solutions, or will there always be a place for them in this world?
