These are still relevant even in modern Java or C# or C++. Just because the language can express things in a more modern way doesn't mean you always will. Or should. Or can.

And I agree that it's a historically informed perspective. But guess how much code is modern code versus historic^W legacy code. Nobody is arguing (well, at least I'm not) it's a foundation of CS. Nor is any reasonable person arguing it's a normative prescription - see the comment about "not a recipe book".

It's the equivalent of a dictionary/thesaurus for a writer - necessary, but not world-changing. Always has been. Still is.
