"Ender's Game" was a great read, the movie not so much.
Also recently read "1984"...once again after 50 years. Back then the technology didn't exist. Scary, scary how accurate it is now. It should have been titled "2024".
One of the underlying themes in 1984 was the continuous work to rewrite history, by going back and "correcting" the history books and newspapers, repeatedly, depending on the current propaganda need.
This is one of the reasons I like having actual hardcopy for more controversial books...like old history books, dictionaries and the classics. Revising history and changing the traditional meanings of words is a constant pressure.
I can envision a time when e-Book content could be 'corrected' without notice or discretion by history revisionists, making it so the holocaust or even the US Civil War never really happened.
