Me as well. One of my formative experiences was reading Refactoring (Fowler). At the time I felt skeptical that it could make a difference --- I had mostly written scientific/research code at this point. I decided as an experiment to apply it to a dissatisfaction I had with the structure of a codebase and it was a revelation. It really made it really concrete what people meant by "a codebase is a system", made me see code from a higher level, almost like a continuous tissue or web you could pull and prod. It's quite sad to think this experience might be on its way out, and it really highlights that "junior problem" from AI. There is just no way around diving in to get an intuition for things. Naur warned us of this 40 years ago but the lesson never seems to get learned.
