Lord of the Flies - William Golding

Starship Troopers - Robert A. Heinlein

Comment:

This book is one of my favorites. Ender's Game was first written as a short story in 1977 and then expanded into a novel in 1985. While it did exist, the internet (the "nets" in the book) was not widely known about or used. Card hit the mark on both the internet and laptops (desks).

Question:

Given what else Card predicted, what else in Ender's Game, either technical or social, is a possibility?
