🤔 Brief reflection

Today, for the first time, I tried vibe coding with GitHub Copilot Agent, or so-called “coding by talking.”

It began with discovering the Warp terminal.

In my existing iTerm2 terminal, I wanted to rename multiple folders at once, so I was looking for a command.

But then I thought, could AI not find that command for me too?

That is how I found “Warp terminal,” which has an AI Agent built into the terminal. The experience was so satisfying that I ended up getting into the Agent mode of GitHub Copilot built into VS Code as well.

Needless to say, the experience was astonishing.

I had only meant to try it for a moment, but around 1 p.m., I stopped listening to the course and fell into vibe coding. It was almost 3 p.m., the stream end time, but time like that was not important to me at that moment.

I kept going until 7 p.m., and even after I had to go out, I continued at a cafe and went all in on vibe coding until 9:30 p.m.

It was so fun.

Of course, as I already knew from its limitations, the bigger the project got, the more frustrating it became. Sometimes it also randomly wiped out all the work it had done, which made me furious. Still, it felt like becoming a CEO who had hired one ultra-elite experienced new employee with infinite energy for free.

If I had not taken the course, I would not have been able to properly request what I wanted from that employee. It is right to finish the course to the end.

But after finishing the course, I think I can focus only on developing apps I will actually use while receiving help from various modes such as Agent, Recommendation, and Ask.

And… I should increase my English study time. The quality of work is clearly different when I request something in Korean versus English. On top of that, the latest information is all in English. There is no time to be running translators.

Now English has become somewhat familiar, and in most cases I can use it fairly freely, so my study method going forward is simple.

Talk with Gemini in English.

Watch more overseas YouTube channels.

Read development-related documentation directly in English.

If my English reading and writing speed reaches even 70% of my Korean speed, I really might be able to fly.
