But like all power, there are those who want to keep it for themselves. The world's entire scientific and cultural heritage, published over centuries in books and journals, is increasingly being digitized and locked up by a handful of private corporations. Want to read the papers featuring the most famous results of the sciences? You'll need to send enormous amounts to publishers like Reed Elsevier.
Books are totally useless unless you take their advice. If you just keep reading them, thinking "that's so insightful! that changes everything," but never actually doing anything different, then pretty quickly the feeling will wear off and you'll start searching for another book to fill the void.
