You need to read better fiction. Look around you, speculative science fiction is what inspired the world you live in; it created this reality. You have global communications via satellite because Author C Clark wrote a piece of fiction that sprung the idea upon the world. Fiction generates ideas, to think that somehow doesn't matter because it hasn't happened yet is massively missing the point.
Not disputing your general point, by Clark's original description of geostationary comsats was in a letter to Wireless World magazine, followed by a paper in the same publication [1]. It wasn't popularised via fiction, although later he did write some fiction that used the idea.
