I guess one counterpoint would be Alfred Einstein and him famously not knowing his own phone number. He stated why would I waste brain cells on something that is alphabetically sorted in a book? I agree you need to know things like how malloc() works, how a function (lets say c) is allocated on the stack into frames, etc.... Just wanted to throw that out there. I love not knowing everything, but that has come after many years of learning what I don't need to memorize/internalize.
