[Text is] a very flexible and pliable medium. You can skim or search. You can copy and paste. You can read at your own speed. It’s simple and cheap to produce and store and share. That’s what gives it its power. Even when you bring media into a high-computing era, you can still do a lot more and more easily with text than you can with video or audio or software.
