Orwell was dealing with communism and his disillusionment with communism in russia and what he saw the communists do in spain. his novel was a response to those political situations. whereas i was interested in more things than the political atmosphere. i was considering the whole social atmosphere: the impact of tv and radio and the lack of education. i could see the coming event of schoolteachers not teaching reading anymore. the less they taught, the more you wouldn't need books.
Science fiction is any idea that occurs in the head and doesn't exist yet, but soon will, and will change everything for everybody, and nothing will ever be the same again. as soon as you have an idea that changes some small part of the world you are writing science fiction. it is always the art of the possible, never the impossible.
