We Are Legion (We Are Bob)

 Young CEO dies young, but got to have his brain frozen. He is revived centuries later and learns that Earth is not going so well. He is to be the AI behind a spaceship to find another liveable planet. He becomes a Von Neuman machine, replicating himself and discovers that his copies are never exactly himself -- version of himself that named themselves after pop-culture characters. There is a Riker who is a bit military and yet peaceful. 

 This is the first volume of a sci-fi book based on classic ideas. It had a lot of potential and the space battle are quite realistic - physics wise -  but the writing was not really thought through: the bobs all have the same voice
