Given sci-fi authors regularly speculate about all sorts of potential futures (and presents), is it really that hard to imagine that some of these futures might come true in some shape or form? It's really rich to trace modern implementations to decades-old ideas and then claim you were the one to create them. Get to pat oneself on the back while wagging a finger at the folks actually doing the building. Zuck's Metaverse would've likely existed without Snow Crash, though probably with a different name. And Motorola Razr would have likely existed without Star Trek communicators. I am not saying that all modern innovations are good ones or that some inspiration didn't take place, I just find the argument that their existence is entirely rooted in science fiction a weak one and full of survivorship bias.
