I barely posted to my feed either. This was not laziness. It was a conscious decision. I had already decided on April 30 that I would stop. The reason is simple: I no longer felt I needed it. Or more accurately — could it have a better form? I want to use my own product. It is not perfect yet, but I want to fully think through and ship the thing I have in my head. The remaining steps are few. It is close. ...

Preface: This article was written on a night in Lhasa. At an altitude of over 3,000 meters, the air is thin and the stars are very close. One evening I stood in the courtyard, alone, and watched the moon in the sky for a long time. That moon doesn’t lose a bit of its light because of AI’s existence. The moonlight is still truly beautiful — What do humans still possess in the AI era? ...

During a 48-hour engineering task, I wrote down one sentence: “At this point, I’ve spent half the time designing, researching, understanding the requirements, judging the boundaries, and developing my taste and intuition. I haven’t started writing code.” The task began as a limited feature. After I kept discussing it with AI, it quickly grew a product model, system boundaries, and a complete design. Every step had a rationale. Every piece connected to the next. I could feel myself thinking faster and farther, holding more layers in mind at once. ...

At the beginning of 2026, my GitHub contribution graph stayed nearly blank for several weeks. A few months later, the same graph showed hundreds of contributions in a single week. In July, this blog published 55 articles in Chinese , while GitHub’s contribution calendar recorded 733 contributions. Those numbers prove neither quality nor user value, much less a business result. GitHub also makes clear that contributions may include qualifying commits, pull requests, issues, reviews, and other activity; the number cannot simply be relabeled as a commit count. GitHub’s profile contributions reference ...

At dusk, I sat on the rooftop of Youli Café and raised my coffee cup toward the twin pagodas of Kaiyuan Temple. The camera recognized the distant towers and ignored the hand in front of it. Cup and fingers dissolved into a red blur; across the old city, the pagodas held their edges. ...

This is a thought experiment-style simulated interview. The respondents are composed of organizational psychology and organizational economics perspectives, and do not represent any real individuals’ original statements. In my June 2026 monthly review, I wrote: Incentive structures colonize personality. At that time, I studied several founders and observed myself. An organization initially selects a particular narrative, user model, and revenue framework primarily to launch a business. Years later, that structure reverses to filter what members can see, what they are willing to acknowledge, and which behaviors persist. ...

I had only asked my second brain to organize the thoughts of a friend. It placed scattered notes in order by time, theme, and cause, then tried to explain how she thought about work, money, and freedom. A few thousand words later, I looked at the resulting portrait and realized that the person it had revealed most clearly was not her. It had shown me why I never stop building systems. ...

This piece is a thought experiment in simulated interviews. The respondents are synthesized from existential philosophy and behavior design perspectives—this is not verbatim dialogue from any real person. One June day, perhaps like this. I woke around noon. My phone lay on the pillow. First I checked the time, then the messages. Nothing was urgent, so I opened a short video. The algorithm did not require me to decide what came next. By the time I looked up, more than forty minutes had passed. ...

This piece is a thought experiment in simulated interviews. The interviewees are synthesized from field anthropology and documentary practice perspectives and do not represent any real person’s actual words. I work with AI, yet I am consistently moved by life outside of AI. The blackness of caves in Laos, the sting of a wound after a motorcycle fall, the wind along the Mekong, a stranger who read a story in my eyes, and the stretched-out time of walking instead of riding on the Four Thousand Islands—none of these experiences has model-like efficiency or can be reproduced with one click. ...

This piece is a thought experiment in the form of a simulated interview. Its two fictional voices combine perspectives from behavioral decision research and high-risk outdoor practice; they do not represent the words of any real person. Nothing here constitutes investment, medical, or outdoor safety advice. In May 2026, I injured my leg in Vang Vieng and still walked into the cave. Over the past two years, I’ve also been able to leave traditional systems, live long-term abroad, and place both income and identity within greater uncertainty. ...

This piece presents a thought experiment in simulated dialogue. The respondents are synthesized from phenomenological and psychotherapeutic perspectives and do not represent any real individuals’ words. It is not intended as psychological diagnosis or therapeutic advice. I excel at stepping back. Entering a city, I quickly see how its industries, spaces, and history shape life. Entering a relationship, I analyze attachment patterns, projections, scarcity, and familiarity. Developing a product, I first deconstruct systems, identify boundaries, and map information flow. ...
