consuming many different types of information will only continue.” We need not worry, though, because our “human software” will in time “catch up to the machine technology that made the information abundance possible.” We’ll “evolve” to become more agile consumers of data. 38 The writer of a cover story in New York magazine says that as we become used to “the 21st-century task” of “flitting” among bits of online information, “the wiring of the brain will inevitably change to deal more efficiently with more information.” We may lose our capacity “to concentrate on a complex task from beginning to end,” but in recompense we’ll gain new skills, such as the ability to “conduct 34 conversations simultaneously across six different media.” 39 A prominent economist writes, cheerily, that “the web allows us to borrow cognitive strengths from autism and to be better infovores.” 40 An Atlantic author suggests that our “technology-induced ADD” may be “a short-term problem,” stemming from our reliance on “cognitive habits evolved and perfected in an era of limited information flow.” Developing new cognitive habits is “the only viable approach to navigating the age of constant connectivity.” 41
    These writers are certainly correct in arguing that we’re being molded by our new information environment. Our mental adaptability, built into the deepest workings of our brains, is a keynote of intellectual history. But if there’s comfort in their reassurances, it’s of a very cold sort. Adaptation leaves us better suited to our circumstances, but qualitatively it’s a neutral process. What matters in the end is not our becoming but what we become. In the 1950s, Martin Heidegger observed that the looming “tide of technological revolution” could “so captivate, bewitch, dazzle, and beguile man that calculative thinking may someday come to be accepted and practiced as the only way of thinking.” Our ability to engage in “meditative thinking,” which he saw as the very essence of our humanity, might become a victim of headlong progress. 42 The tumultuous advance of technology could, like the arrival of the locomotive at the Concord station, drown out the refined perceptions, thoughts, and emotions that arise only through contemplation and reflection. The “frenziedness of technology,” Heidegger wrote, threatens to “entrench itself everywhere.” 43
    It may be that we are now entering the final stage of that entrenchment. We are welcoming the frenziedness into our souls.

Human Elements

    A s I was finishing this book late in 2009, I stumbled on a small story tucked away in the press. Edexcel, the largest educational testing firm in England, had announced it was introducing “artificial intelligence-based, automated marking of exam essays.” The computerized grading system would “read and assess” the essays that British students write as part of a widely used test of language proficiency. A spokesman for Edexcel, which is a subsidiary of the media conglomerate Pearson, explained that the system “produced the accuracy of human markers while eliminating human elements such as tiredness and subjectivity,” according to a report in the Times Education Supplement . A testing expert told the paper that the computerized evaluation of essays would be a mainstay of education in the future: “The uncertainty is ‘when’ not ‘if.’” 1
    How, I wondered, would the Edexcel software discern those rare students who break from the conventions of writing not because they’re incompetent but because they have a special spark of brilliance? I knew the answer: it wouldn’t. Computers, as Joseph Weizenbaum pointed out, follow rules; they don’t make judgments. In place of subjectivity, they give us formula. The story revealed just how prescient Weizenbaum had been when, decades ago, he warned that as we grow more accustomed to and dependent on our computers we will be tempted
