He was definitely one of the most influential writers for me. He was really prolific. He wrote about science, science fiction, history, religion. He wrote novels, short stories, essays and textbooks. In everyone of the books I read I could see a message, a message which I identify with. He saw the future in a way few people have done. He created the 3 Laws of Robotics which now seem logical for the development of robots.
Isaac Asimov's novels show us a fantastic and real universe at the same time. Humans behave as they always have, but they can travel to and from the stars. They can jump from planet to planet, however the politics, philosophies, religions are similar to ours. You can see an internal debate, which I am sure also went on in his mind, about what is more important, the individual or the society. He shows how can different concepts could be positive or negative, depending on the perspective of the observer. Civilizations rose and fell in his novels, just as it has happened in real history and as it probably will continue to happen in the future.
He died in 1993, after leaving a legacy of more than 500 books for us to enjoy. People will talk about him for centuries, will discuss his ideas and will be thankful for all his work
