Hey, it seems like you took this as gatekeeping or something. These skills can definitely be taught or self-learned, I've done it and seen it done many times.
My point was only that I don't know resources that can act as a shortcut (my actual word above), i.e. ways to skip over the longer path of gaining experience through long engagement with the topic. So maybe more like a chess coach saying they don't know any books that let a beginner jump ahead to being a more experienced player?
There are hundreds of past threads on HN about books to level up in software, so clearly some people have thoughts about this. I just don't know what to recommend a data scientist who needs these skills immediately.
