I put this book away at the library. It's a new sci-fi novel. It's called 'Fitzpatrick's War' and it's about a guy living in the 26th century. Only get this- before the 2500s, humanity got screwed up along the way- and all of a sudden the internet, electronics, everything got wiped out. Now humankind is just rediscovering steam power and heavier than air airplanes- more than 600 years after they were first created.
Think about it- World War Two happened, man went to the moon, Bill Gates got rich off the internet. 500 years later, when we envision us as a galaxy spanning species with lasers for eyes, we're riding on horses and 'inventing' flintlock rifles.
Wrap your head around that one, Grasshopper.
