It's a nice read but I doubt that the idea delivers what it promises. I think one could downsize the idea to: if you learn one topic deeply you (probably) touch surrounding topics. That does not sound as elegant and holistic as in the article but is IMO closer to the truth. I would call it a huge exaggeration to say I've learned things about the world when in reality I just became a really good software engineer that knows how to interact with OSS communities.

These ideas are repeated often and I lean more to the specificity side of things: you only get good at what you learn/train. You won't become better at decision maker by learning chess/poker, you won't (or just become a slightly better) endurance swimmer by becoming a good runner, you won't understand human psychology by getting good at coding.

I remember a talk of top-notch mathematics where they were asked about related mathematical topics and most of them would just answer something like: "I just try to understand my field of mathematics well, I can't say much about something else". This was the discussion from the Breakthrough Prize in Mathematics 2015: https://www.youtube.com/watch?v=eNgUQlpc1m0&list=PLyF3OMOiy3...

This is the correct answer. The rest of the replies are cope from people who do nothing but study CS and SWE and think that therefore makes them knowledgeable of everything.
