The story rigidly adheres to the speed of light, except, you know, wormholes. The protagonists have access to six million years' worth of technology, except, you know, lack the common sense to take reasonable precautions after a disastrous ambush. Advanced AI features at the start and end of the story, but somehow, you know, isn't in use all over the galaxy.
Some interesting, even provocative ideas, but ultimately not enough to match the daunting scope of a six million year timeline. All that fuss, and it all boils down to people just not being able to get along?!
