[📝] Today Was #228: Humility Learned in Front of Professionalism

✨ GPT-5.5’s Summary

A day when I looked back on my confidence in vibe coding, the consistency of an outsourced groupware deliverable, and my own arrogance.

💭 Diary

People really do need humility.

A few days ago, when I saw the groupware that another company had supposedly spent a year building after our company outsourced it, I honestly thought, “If I had built this, it would not have taken even three months.”

Even though vibe coding with AI has many weak spots, I still thought it was possible to improve it enough. If I proceeded carefully with TDD, and if I built proper harnesses to prevent recurring issues, that should be possible. Big Tech companies that are serious about AI also seem to be moving toward a point where the share of developers who code directly keeps shrinking.

To be clear, that opinion has not changed at all. If AI is used well, tests and harnesses are laid down properly, and recurrence-prevention structures are built carefully, I still think development speed and quality can change a lot.

But I did feel that I needed to repent of the arrogance behind “it would not have taken even three months.”

Recently, I have often developed in this pattern. I go back and forth with agents, keep improving the harness engineering structure, prevent various issues from recurring, add new features, take feedback, and fix things again. For repeated work, I create worker/coordinator agents and run them.

That routine gave me fast development speed and quick changes of direction, and it also did a decent job of preventing similar issues from recurring. But it was weak at tying the whole product together under one planning and design philosophy. So I could push implementation quickly, but the design, functional, and product-planning consistency was very low.

Still, I do not see this as an inherent limit of vibe coding. It is closer to the fact that I have not yet sufficiently embedded planning, design, and documentation standards into my harness engineering.

But when I saw the outsourcing company actively using Figma to record various frameworks, descriptions, and flows for the groupware, it became clear. There was a professionalism different from my way of charging in without enough structure. The high consistency of their planning documents and deliverables gave a strong sense of trust.

Their professionalism also showed in the GitBook manual. I had only thought, “If I build it well enough, users will figure it out. If the UI/UX is intuitive, that should be enough.” I had never even imagined making a guidebook for internal staff.

Of course, if the UX is good and the help buttons are placed intuitively, I still honestly wonder whether a guidebook is really necessary.

Anyway… I still think minimizing LLM use and coding directly is a fairly old-fashioned development culture and hard to recommend. But I clearly realized that I am not yet at a professional level where I can lightly look down on them.

Always be humble. Always learn.

🤖 GPT-5.5 Coaching

Execution: Elon Musk | To Make Imagination Real

• Verdict: ★★★★★ (5/5) You completed every core goal and task, and left a concrete work record around learning the groupware and supplementing data. Today’s execution was not just “doing a lot”; it built the basis for the next deliverable by learning tools and processes inside a real company environment.
• Question: While keeping implementation speed, what should you observe first if product-wide consistency is to be treated as part of the deliverable from the beginning?

Monitoring: Socrates | To Know Myself

• Verdict: ★★★★☆ (4/5) It was good that you did not pass over the thought “it would not have taken even three months,” but named it as arrogance. Still, while you recognized the outsourcing company’s professionalism, your judgment about direct-coding culture remains strong, so the boundary between criticism and contempt needs continued inspection.
• Question: Did you really see their slowness, or did you see the cost of consistency that you have not yet fully handled?

Health: Hippocrates | To Make the Body the Honest Ground of Life

• Verdict: ★★★☆☆ (3/5) A weight of 85.8kg, total 1636kcal, and 7500 steps were not bad on record, but the meals centered on chicken skewer, triangle gimbap, sundae gukbap, ramen, and rice were not meals that raised body quality. Still, on a day without cardio or strength training, keeping the step count was at least a body signal you held onto.
• Question: Was today’s body closer to “it did not collapse,” or closer to “I roughly fueled it just to get through work”?

Philosophy: Nietzsche | To Live as a Peaceful Übermensch with Jesus

• Verdict: ★★★★☆ (4/5) You held onto your strength in fast implementation while also admitting weakness in front of external consistency and documentation. Because you recognized something to learn instead of merely displaying power, today’s reflection was closer to an honest adjustment for becoming stronger than to cynicism.
• Question: Is the strength you truly want the strength to build faster than others, or the strength to create an order others can trust?

Inner Faith: Augustine | To Set the Order of Love Right

• Verdict: ★★★★☆ (4/5) Today’s record clearly showed an inner movement of noticing arrogance and trying to hold onto humility. But the thought “if I had built it” may have included not only ability, but also a desire to feel superior, so what matters is whether the order of love returns from achievement to honesty before God.
• Question: What did I love more today: an actually better product, or the feeling that I was better?

Practical Faith: Bonhoeffer | To Move Beyond Cheap Grace into Responsibility

• Verdict: ★★★★☆ (4/5) It was good that humility did not end as a feeling, but came down into concrete responsibilities such as learning the groupware, scanning the contract, supplementing data, and improving prompts. Today’s faith was tested not by a perfect attitude, but by lowering judgment, learning what had to be learned, and carrying out assigned work.
• Question: If today’s humility does not disappear as a feeling, what shape of responsibility should it leave in tomorrow’s work?
