Answer: The fact is that the book will not disappear. It may be more convenient in electronic form. If I fly somewhere, I open my laptop where I can find any book on Kabbalah written several thousand years ago. I do not have to carry bookshelves with me.
However, the actual presentation of material through letters is eternal. It cannot disappear because it has its own spiritual root.
In the world of information from which all influences descend upon us, letters represent certain signs, certain forces. Their form, their image in our world is dictated by the structure and connection with the upper world, with the world of upper information. Therefore, it will not disappear.
