People are okay, but they're nowhere near as cool as books....well except maybe the ones who wrote the books, but even then I'm quite certain I'm right in saying that they wouldn't turn out to be as fascinating as their characters (I'm optimistic like that).
Let me tell you why a book is man's best friend (I am obligated at this point to inform you that I have never had a canine companion and so I could be wrong). Books tell you everything, they treat you like their confidante. They will tell you the greatest story you have ever heard, they'll move you to laughter, or to tears, or sometimes both at the same time, inspire you, teach you, even change your life and ask for nothing in return (yes, you need to buy them, but that's beside the point). They don't even care how badly you treat them. And best of all, books don't judge you- they are just there for you, in sickness and in health.
Like I said, people simply cannot compare (except, we sort of need them to do the actual writing of the books themselves...but maybe someday we'll have AI for that too).
A reassuring (and simultaneously scary) thought is that there are more books in the world than you can possibly read (seriously, they actually tried to count - apparently there are approximately 130 million books!).
And who cares if the stories contained within their pages aren't real? What does real mean anyway?
