Did you know that much of what we use now was created in the minds and with the help of the imagination of science fiction writers many decades ago? That is, first they introduced these objects as part of the fantastic world into their stories, and then these devices became part of our modern culture. It sounds amazing! Thirty years before the tragic explosion of the atomic bomb in Hiroshima and Nagasaki, H. G. Wells described this phenomenon in his book. The French writer Jules Verne was the first to mention the analogue of a modern helicopter and a submarine. The Strugatsky brothers awarded the hero of their book with virtual reality glasses. In Ray Bradbury's stories, something similar to a wireless phone and a plasma screen appears in the stories. Many writers have gone further. In one of the works, you can read about an analogue of artificial insemination which was described by John Haldane, a bionic limb in a book by Martin Kaidin. Another interesting fact: it was only in 2000 that a computer managed to beat a chess champion for the first time. In the literature, this case was described seven years earlier. Time is moving forward and perhaps what we are now reading about in science fiction books will become a reality and the predictions will come true. Who knows.
