Let’s assume, an elderly uncle from our neighborhood, sitting at the local tea shop, simultaneously proud and regretful, says: "When I first entered class five, there was so much celebration and joy about it—I remember all of it so clearly. But tell me, the other day, I can't even remember what I had for lunch!"
Hearing such instances of memory loss from elderly people like our uncles, we realize that no matter how much one clings to memories, many of them gradually fade away over time. We remember the joy of topping an exam in childhood, yet we can't recall where we placed our keys just yesterday.
This play of memory makes life a bit mysterious, somewhat humorous, and even tragic. In the midst of this memory complexity, when modern technology opens up the possibility of storing our memories in machines, it’s not just a scientific marvel—it becomes a philosophical and ethical question: "Are we truly ready to hand over our memories to machines?"
Recently, scientists in Korea have developed a device that can potentially surpass the human brain in storing memories. This device, called "PCL-Tempo," can be implanted in the brain, eliminating the fear of memory loss. It can be inserted into the brain without surgery, and when no longer needed, it dissolves in water—leaving no waste.
It almost sounds like magic, but it’s science. This device supposedly can even store everyday events as memories. Meaning, it can record whether you brushed your teeth in the morning, how much rice you ate at lunch, how many times you secretly cursed someone or a superior—everything can be recorded!
But in addition to the marvel of technology, there are also other questions to consider. Scientists claim that memories can be erased on demand. If someone wishes, the memory of being rejected in love or humiliated at the office can be completely "deleted."
People naturally wish to cherish happy memories and forget the sad ones; however, in reality, it is from sorrow that people learn, and from happiness that they find inspiration. That’s why memories are so important, and maintaining them is a delicate and responsible task. Erasing memories could also be dangerous from a human value standpoint.
If a criminal erases their memories, they might believe they are innocent, and no remorse would arise in them. What if someone steals someone else's memory and uses it to deceive or blackmail them?
Memories are not just "data"; they are a complex chemistry formed by emotions, perceptions, and experiences. Everything we read, see, or hear doesn't always stay, but the parts that touch our hearts become the core of our memories.
So, if a machine only stores data, where does the feeling go?
Scientists say that when humans depend too much on machines, the effectiveness of their own brain diminishes. Memory, like a muscle, weakens if not exercised. If people no longer feel the need to remember, one day, perhaps, memory itself will disappear.
Memory is a bridge that connects the past to the present and moves towards the future. If technology is ever able to preserve human memories, people will have to understand its pros and cons.
Otherwise, one day, we might find ourselves sitting in the same tea shop, with an elderly uncle saying: "I remember when I was in class five... the rest, I don't know, because the device wasn’t updated!"
