History of Enders Game

The book Enders Game was first published in 1985. This gives me a understanding that in 1985 people thought about sci-fi in the same sort of way that we still think of sci-fi. Although we have had major technology advancements such as iPhones and iPads people 30 years ago were thinking about these advancements and were writing about these advancements in books. There are also many books and movies that are about the military genre and soft sci-fi and these have not changed over 30 years.
