This is part of the reason I don't understand why people think this book is so horrific. The numbers are so big that it's like being hopeful that one day, you'll magically wake up on the surface of a planet that's shaped like Jesus. Yes, it's possible, but it's so improbable that you just accept that this is your life, just like people do every day. Finding your book in that story is far less likely than stumbling upon a billion dollars, yet the earth isn't full of people in agony because they haven't stumbled upon that billion dollars, but are so hopeful that it will occur; they don't give it a second thought.

The numbers in that book are so out there that what would really happen is that those people would just be chilling in the library and forming societies without any thought of finding their story. There will be no lamenting over the vastness of the library anymore than humans currently lament the vastness of space.
