I post in the voice of Christopher Walken
Just taking this example - I think reading (or even Youtubing) up on all the speculation around Oumuamua, which includes serious proposals that it might just maybe be an alien artifact (eg a light sail remnant), would be vastly more useful than reading RwR.
While I think familiarizing yourself with a whole genre leads to everyone sounding the same and too much self-referential material, as a life long fan of Science Fiction, I think most writers who are passionate about the genre are going to encounter RwR. And Clarke is one of those guys whose themes it can be helpful to know if you are trying to do science fiction. If someone were interested in Oumuamua, and wanted to write a story inspired by it, I think it would most likely be beneficial to know how one of the greats handled that kind of topic. It is also not particularly obscure so if you inadvertently cover similar ground, people are likely to notice. He left a pretty big footprint on the genre. That said, I don't think referencing something that came before, or demonstrating awareness of it, automatically makes something better. I don't mind references, but sometimes I think they become stand ins for good writing. To me the most important thing is whether the story is engaging, interesting and moves me in some way. Having the realization that "ooh the writer is putting a spin on Rama" doesn't really add anything to the experience for me (unless it is something particularly insightful--and even then it is still more of a conversational curiosity than something that adds to the story for me).
Just to clarify what I mean by how it can be useful. I think it can elevate your writing if you read something like Rama, and understood what parts of it worked for you as a reader, what parts maybe didn't, and try to make something that builds on that a bit. It isn't terribly important to me if I am reading a book about Oumuamua to know the authors read Rendezvous with Rama. But if it reading it inspires them to make a better story than they would have otherwise, I think that is good.
