Predicting the future, but it's already here

I was reading the GoodWeekend magazine that comes with The Saturday Age when I noticed a story about something I wrote about in the novel I'm currently revising. It's set about 1500 years in the future, but apparently webrities are already here. A webrity is a celebrity who is web-based. They aren't a physical being, but they have a personality, act on a show or make music (or whatever they're famous for) and generate gossip and speculation like any other celebrity. In the GoodWeekend story ('Sound of the Future' by Mark White) I learned about Hatsune Miku who is a Japanese singer. She has performed with the Japanese Philharmonic Orchestra and will star in an opera in Paris in a few months, and she's a computer program. I was excited to see that an idea I had come to independently and creatively for the futuristic world of my novel is actually realistic and possible – not just in terms of technology, but psychologically, in terms of fans buying into a webrity. I don't know that I'll be a major writer in the speculative genre, but I could see how it might be addictive.
