It is a shame they haven't caught on, but I believe there's a positive-feedback mechanism in advertising these ideas. Once an ingenious idea is made, it is only disseminated to a smaller percentage of people. One of these people then has to be inspired enough by the idea to borrow from the original creator.
If the idea is borrowed, it is likely to live on for longer. If it gets borrowed in a movie, the idea will go global due to the sheer amount of people who will receive the idea compared to reading a sci/fi book.
Once the idea has been spread enough, it will get borrowed enough. Before Asimov, robots were basically a chromed Frankenstein. However, now it's rare and rather dated to see a Frankenbot. Now it's typically benevolent robot/AI hurts humanity to help it, which was a frequent element in Asimov's own work.
Megastructures haven't really appeared in Hollywood movies before. There was the Deathstar and the planetary ring in Verhoeven's Starship Troopers, aside from that I seriously can't think of another without seriously stretching it. So until we see an actual-factual ringworld or dyson spheres, which are far more recognised ideas, I doubt we'll see a matrioshka brain, even though it has the biggest uses.
