I don't share this way of thinking of "relevance". Are Newton's principae mechanicae (+300yrs) still relevant? Obviously yes, they form what we call today "classical mechanics". Every student learns it, despite of course the best theories in physics are quantum mechanical or/and general relativitistic ones. What about the ancient Greeks? They frontiereed in math and philosophy and many proofs are almost 1000 years old. That's how science works. All the items you listed are classical building blocks of computer science and will remain that forever, even if people come up with successor ideas.
