Strangely enough, even in this video, everyone notice how you're taken to make tradeoffs between coherence and cleanliness vs performance-oriented code in langs like C++, while the Clean Code book was exemplified in Java (so most of performance is shoved in JVM code) and SICP was in Scheme (which is interpreted, or transpiled to C where you can optimize, or has a VM/JIT underneath). I vaguely smell the language of choice has something to do with that, and C++ would benefit more from data-oriented design than from literate OOP or functional programming patterns took from very very different programming ethoses (the programming language is an interface to something else)
