However, since I am Korean, I am not in a position to take work from American defense contractors. Still, your analysis is very interesting to me.

I am also a factory/industrial software developer in Korea, and the situation feels somewhat similar. Many developers are leaving factory software work because of the travel burden and the heavy responsibility. If the system fails to operate correctly, there can even be penalties. I am still doing this work because I need the money, but it is interesting that American defense contracting and Korean factory software seem to behave in somewhat similar ways.

Recently, I was also told that using Chinese models such as DeepSeek is prohibited for some products that go into factories. So at the government-related level, this seems to be restricted, though I am not sure how things are handled in the private sector. From what I can see, private companies still seem to use them.

In any case, your comment was very interesting. You pointed out something I had been missing. Thanks to you, I now have many things to think about. Thank you for the thoughtful comment.
