Another way Cader's "paradigm shift" might come about is through the evolution of the entire publishing industry. Epstein envisions a huge change in the way books are sold as a result of new technology, specifically print-on-demand machines that can produce a bound copy of any book either while the customer waits or to be picked up after an order is placed online. With the elimination of the costs of inventory, shipping, returns and distributors' markups, the price of books would go down and authors might make more money from their work.
