“You should have various experiences in your campus life.” That was the advice given to me as I was about to enter POSTECH. I completely agree with the tip, and it seemed I was confident enough to accept it. Looking back, that period was marked by significant interest in the question, “Where can artificial intelligence be applied?” Given that artificial intelligence (AI) has been creating wonders by assembling theories of AI, high-quality data that could be material for everything, and computing resources, I am hopeful about creating an AI model that defines the correlations between different areas of knowledge and optimizes the direction of scientific research. Around this time, a new possibility started to unfold. I am referring to the “Large Language Model” better known as ChatGPT. I would like to define it as an “emotion generator that provides unexpected results and influences how surprising the user can be.” Do you agree with my definition? It is up to you. Anyway, as I write this, I decided to major in quantum computing which is completely different from what has been mentioned so far. The narrative might seem a bit odd, but I hope you will take your time to read through it all.
  When I was preparing as a player for the science quiz of the 2021 Cyber PKSW, memorizing the Turing Award winners was a painful task, but studying the history of computers was fascinating. Then, I discovered that after the invention of vacuum tubes, transistors, and integrated circuits, it took 37 years, 7 years, and 5 years respectively for computers using each of these components to be developed. Now it is a period of using microprocessor computers based on a very large-scale integration, crossing over beyond integrated circuits. So, it really gets you thinking, what is the next generation of computers? What will you be doing with the computer you will be using 50 years from now? Paralleling the history of classical computers and quantum computers, I believe that today’s quantum computing technology is approximately at the stage of the year 1943 in the classical computer timeline. 80 years after the invention of ENIAC, when we think about what can be achieved with computers, we can sense that a revolution as significant as AI is already on our doorstep. To the readers of this article, I would like to ask: What problems do you envision solving with quantum computing?
  This writing started with a tip. The reason I mention this advice is not just to teach you, but also to introduce a contrasting viewpoint: “If you want to converge, you have to dig your own deep well.” When these two pieces of advice are integrated, something ideal and ironic words “A well both wide and deep” are made. Looking back now, I find myself agreeing with this statement. Although I want to dig such a well, choosing where to dig is the real challenge. Perhaps a well of one’s own is not necessarily a straight hole after all. At that time, there was a need for the thought that water is not found only directly below our feet. I hope that for some, various experiences, and others, deep experiences, become their wells, making us a team that supports each other. And who knows? Maybe this article will help someone who has been hesitating, shovel in hand, uncertain of where to begin their journey, leading them to tread a path akin to mine.
  I would like to end this article by thanking God for granting me his wisdom to complete this writing. Thank you for reading these words.
