What is your feeling on books?  Do you think they could be used for something other than stacking?  I have a few ideas myself but just wanted to check in with you first.
they are incredibly useful and powerful, but then there were some subsequent inventions which did what they do much better. this doesn't make books any less powerful, it simply means there are more powerful tools available now, which can do everything books do and more, or the exact same amount or even less, depending on what you prefer
