Sci-fi and the internet

I have been hearing many people say that the writers for science fiction, despite coming up with interstellar travel, advanced weaponry, and many other ideas for great technology, were not able to think of anything like the development of the PC or the Internet which are the some of the greatest technologies of the modern era. However this is not necessarily true.
There is Algis Budry's 1977 novel, Michaelmas, which describes a worldwide web of telecommunications and computer data. There is also Vernor Vinge, who wrote a novel in 1981 called True Names, which anticipated a cyberspace that is recognizably our own. Most notably, William Gibson invented the "consensual hallucination" of the Matrix in the 1984 novel Neuromancer. An to go farther back, Jules Verne tells of people getting information of the news in something similar to an internet. These people and their works have greatly influenced the advancement of technology and I say that the modern world would not have been the same without science fiction.
