A book is an attention unit. A fact is interesting, an idea is important, but only a story, a good argument, a well-crafted narrative is amazing, never to be forgotten. As Muriel Rukeyser said, "The universe is made of stories, not of atoms."
Every company creates its own origin myth. It's a useful tool for expressing the company's values to employees and the world and for simplifying and massaging history to give due credit to the people who made the most important contributions back when it all started.
