Reading this article, I found myself agreeing with more of it than I expected, even as a Korean-language speaker.

There are words that are used differently in North Korea and South Korea, but even within South Korean Korean, the sentence endings, vocabulary, and phrasing you should use can change a lot depending on the situation. The basic structure may be similar, but small differences matter.

Vocabulary changes depending on context, relationship, social distance, age, and whether the situation is public or private. North Korean speech is often more direct, but in South Korea, especially in more formal or higher-status social settings, speaking that directly can make a person sound crude or unsophisticated. Formal South Korean speech is often based on cushioning expressions. So even with the same Korean writing system, the rules for using sentences differ slightly.

This is something I feel even more strongly as a non-Western speaker participating on HN. If I do not use AI translation, many of my expressions become awkward. But after asking about it, I understand that even if the original Korean text was written without AI, using AI translation alone may cause the English version to be treated as Gen AI, which means I cannot really submit my blog posts.

So, reluctantly, I write my English comments by carefully combining machine translation, the English I have learned, and manual correction. Reading this article made me worry about how low-quality or awkward my comments may appear on HN.
