History buffs expect historical background in historical fiction. Mystery readers expect forensics and police procedure in crime fiction. Westerns - gasp - describe the West. Techno-thriller readers expect to learn something about technology from their fiction.

The challenge - and much of the fun - of writing in an established future history lies in incorporating new knowledge while remaining true to what has gone before. Expanding and enriching, not contradicting.
