The Year of the Co-Pilot: A 2025 Retrospective

If I were to define 2025, I wouldn’t call it a collection of days, but rather a profound shift in how I interact with the world. It was the year the line between my own cognition and artificial intelligence finally dissolved. The most significant change wasn't just in what I achieved, but in how I achieved it.

The Synthetic Cortex: A New Operating System

AI ceased to be a mere tool this year and became a seamless extension of my agency. From delegating complex life decisions to Gemini to letting it nuance my WeChat replies, I found myself navigating the world with a new kind of confidence.

The drudgery of coding was replaced by high-level orchestration; with AI generating the heavy lifting of the syntax, I was free to focus on architecture and logic. Suddenly, the friction between having a "wild idea" and executing it vanished. This year, my subjective initiative skyrocketed because I knew I had the capability to build whatever I could imagine.

The Academic Rollercoaster: Rejection as Fuel

In the realm of academia, this newfound efficiency was tested against the brutal realities of peer review. My journey to publication was a lesson in resilience. The year began with the stinging disappointment of rejections from both ACL and IEEE S&P, setbacks that made me question the validity of months of work. Yet, redemption arrived in the form of an acceptance letter from AAAI for my work on RAG poisoning. That acceptance was more than just a credential; it was a vindication.

However, the relentless pace has left its mark. I confess to feeling a lingering sense of burnout as I approach my final projects, but the goal for the coming months is clear: to summon the last reserves of my energy and place a definitive, triumphant period at the end of my graduate career.

From Intern to Engineer: Surviving the Gauntlet

While the academic world demanded resilience, the professional world demanded transformation. My time at Siemens BSCE was a glimpse into the future, where I moved beyond theory to help build a Code Review Agent, seeing firsthand how AI integrates into industrial workflows.

But the true crucible was the fall recruitment season. It was a grueling marathon of submitting resumes, enduring endless written tests, memorizing technical trivia, and grinding through Leetcode problems until the patterns burned into my retina. It was a psychological siege, but the fortification held. Signing the offer with Tencent felt less like luck and more like the inevitable result of preparation meeting opportunity. I am ending the year not just as a student, but as an incoming engineer at a tech giant.

Analog Adventures: Mountains, Lakes, and Old Friends

To counterbalance the high-pressure digital grind, I sought solace in the physical world, finding grounding in travel and old friendships. The geography of my year was defined by reunions. I walked the spiritual paths of the Lingyin Temple and the West Lake in Hangzhou with my college roommates, seeking quiet amidst the chaos.

I climbed the imposing steps of Mount Tai and gazed at the endless horizon in Weihai with high school friends, reconnecting with the person I was before the algorithms took over.

Later, I braved the snows of Changbai Mountain, again with college friends, freezing moments in time just as we are about to scatter into our respective futures.

The Physics of Joy: The Physics of Joy: Clear Tables and Open Roads

Back in the daily rhythm of life, I fought a constant, often losing, battle with discipline. My attempts at weight loss were earnest, though frequently sabotaged by the siren call of restaurant menus.

Yet, I found victory in movement elsewhere. Monday and Tuesday nights became sacred rituals for badminton, clearing the mental fog with physical exertion. When I wasn't on the court, I found a different kind of liberation on two wheels. Biking transformed from a simple pastime into a rolling meditation; the rhythmic cadence of pedaling offered a way to physically distance myself from the anxieties of the thesis and the job hunt, letting the wind scrub the code from my mind as I reclaimed the city streets.

Perhaps my most cinematic small win was at the billiards table—clearing the table in a single run for the first time, a moment of perfect focus that felt surprisingly similar to debugging a complex script.

Evenings in the lab transformed into battlegrounds of a different sort, where we bonded over board games like Camel Up, Texas Hold'em, and Las Vegas, finding joy in analog probability when we weren't wrestling with digital statistics.

2026 - The Uncharted Horizon

As the calendar turns, the protective bubble of campus life is set to finally burst, and I find myself standing on the edge of the open ocean. 2026 is not just another year; it is the year of the great migration. The first half will be defined by the final sprint—polishing the thesis, defending the research, and ensuring that my graduate career concludes with the dignity it deserves. But the true gravity of the year lies in what comes after. transitioning from the theoretical sandbox of the laboratory to the high-velocity environment of Tencent will likely be the steepest learning curve of my life. The "Imposter Syndrome" might be inevitable, but I am bringing my co-pilot—my AI workflow—with me. The goal is no longer just to solve problems on Leetcode, but to solve problems for millions of users.

Beyond the career pivot, my promise to 2026 is to protect the analog soul I rediscovered this year. The tech industry is notorious for consuming life, but I refuse to let the "996" culture erode the joy of a Monday night badminton match or the freedom of a weekend bike ride. I want to enter this new chapter not just as a productive engineer, but as a healthy one. The restaurant menus will still be tempting, and the work will be demanding, but if 2025 taught me anything, it’s that resilience is a muscle, and I have spent the last twelve months training it. The map is blank, the tires are inflated, and I am ready to ride.
