When I wrote code, I also loved to understand what I used (including when I took snippets of codes from others, often from online sources). Now I don't care as much, since I doubt I'll go back to coding and yes, I do believe this job is in high danger from the AI, especially if one isn't important enough to be on the irreplaceable side, when the first waves of cutting come. The social side may also matter when decisions are made, so a great programmer without social skills may not be as desired in a group anymore - just a guess.
