Every time society advances, it faces challenges from those people economically and emotionally invested in the past. Undoubtedly stone age flint knappers were less than happy about bronze-age technology disturbing their business model. The medieval church was none to pleased about printing technology breaking their hegemony over knowledge, but wed never have had the Enlightenment without it. Today the media-conglomerates, governments and educational institutions that profit from gatekeeping knowledge of all kinds are pushing the Stop Online Piracy Act, and even more draconian legislation to try and hold back the flood of free knowledge that threatens their power. Unless we want to stay in the knowledge equivalent of the stone age, and miss the next enlightenment the knowledge revolution promises to bring with it, we should all redouble our efforts to make sure they lose.

For centuries the book has been the highest symbol of knowledge. The object that has enshrined and preserved knowledge through history. The book is so inextricably linked with our concept of knowledge that for many people it is hard to separate one from the other. But for human knowledge to reach its full potential, we may have to let go of the book-as-object first, or open our thinking to a radically different definition of what a book is.
