reading and the web....,

NYTimes | Nor is it simply a question of experts and professionals being challenged by an increasingly democratized marketplace. It’s also a question, as Mr. Lanier, 49, astutely points out in his new book, “You Are Not a Gadget,” of how online collectivism, social networking and popular software designs are changing the way people think and process information, a question of what becomes of originality and imagination in a world that prizes “metaness” and regards the mash-up as “more important than the sources who were mashed.”

Mr. Lanier’s book, which makes an impassioned case for “a digital humanism,” is only one of many recent volumes to take a hard but judicious look at some of the consequences of new technology and Web 2.0. Among them are several prescient books by Cass Sunstein, 55, which explore the effects of the Internet on public discourse; Farhad Manjoo’s “True Enough,” which examines how new technologies are promoting the cultural ascendancy of belief over fact; “The Cult of the Amateur,” by Andrew Keen, which argues that Web 2.0 is creating a “digital forest of mediocrity” and substituting ill-informed speculation for genuine expertise; and Nicholas Carr’s book “The Shallows” (coming in June), which suggests that increased Internet use is rewiring our brains, impairing our ability to think deeply and creatively even as it improves our ability to multitask.

Unlike “Digital Barbarism,” Mark Helprin’s shrill 2009 attack on copyright abolitionists, these books are not the work of Luddites or technophobes. Mr. Lanier is a Silicon Valley veteran and a pioneer in the development of virtual reality; Mr. Manjoo, 31, is Slate’s technology columnist; Mr. Keen is a technology entrepreneur; and Mr. Sunstein is a Harvard Law School professor who now heads the White House Office of Information and Regulatory Affairs. Rather, these authors’ books are nuanced ruminations on some of the unreckoned consequences of technological change — books that stand as insightful counterweights to early techno-utopian works like Esther Dyson’s “Release 2.0” and Nicholas Negroponte’s “Being Digital,” which took an almost Pollyannaish view of the Web and its capacity to empower users.

THESE NEW BOOKS share a concern with how digital media are reshaping our political and social landscape, molding art and entertainment, even affecting the methodology of scholarship and research. They examine the consequences of the fragmentation of data that the Web produces, as news articles, novels and record albums are broken down into bits and bytes; the growing emphasis on immediacy and real-time responses; the rising tide of data and information that permeates our lives; and the emphasis that blogging and partisan political Web sites place on subjectivity.
