Today…the familiar letters of the alphabet are more abundant than ever. One of the most astonishing consequences of the rise of digital media, and particularly the Internet, is that we’re now surrounded by text to an extent far beyond anything we’ve experienced before. Web pages are stuffed with written words. Text crawls across our TV screens. Radio stations send out textual glosses on the songs they play…I have little doubt that in 2050 — or 2100, for that matter — we’ll still be happily reading and writing. Even if we come to be outfitted with nifty Web-enabled brain implants, most of the stuff that’s beamed into our skulls will likely take the form of text. Even our robots will probably be adept at reading. What will change — what already is changing, in fact — is the way we read and write. In the past, changes in writing technologies, such as the shift from scroll to book, had dramatic effects on the kind of ideas that people put down on paper and, more generally, on people’s intellectual lives. Now that we’re leaving behind the page and adopting the screen as our main medium for reading, we’ll see similarly far-reaching changes in the way we write, read, and even think.
