Imagine a universe so old and so populated that a good portion of the matter/energy available in the universe must be devoted to storing the histories of the various civilizations. Wars would break out over data resources, as factions war over access to storage and compute power.

That assumes a future where humans colonize the stars and spread life through the universe. What's more likely for humanity is a future more like the matrix, except instead of being enslaved, we place ourselves there willingly. It seems to me the focus of most of our technology has been to figure out how to poke and prod our pleasure sensors to maximum effect. Forget the stars, we're going to invent our own personal paradises on Earth and just stay here.
