I agree with a lot of the points mentioned in this article. But one thing I'm not sure of is how does knowing the deep underlying fundamentals of CPU, memory, http etc . Help you be a better engineer, cause most engineers just work at a very high levels of abstraction and the languages and framerorks used at that level don't allow low level access for memory etc anyway. I mean you should not be clueless about these basic things buy I don't understand the day to day application of it, outside of academia.
I really like the point about reading books. I often notice that some engineers miss a lot by preferring videos and shallow posts over documentation and books.
Also, it strikes me how often people would rather ask a question on something trivial rather than read the docs or at least Google the question.
Being able to search for information is such a crucial skill
