PositiveThe Los Angeles Times[Foer] has crafted an anti-Silicon Valley manifesto that while occasionally slipping into alarmism and get-off-my-lawn-ism makes a cogently scary case against the influence of U.S. tech firms (but not, crucially, technology itself). Silicon Valley, he argues, may say it wants to improve the world. But its true endgame is the advancement of an ideological agenda.? And it's a terrifying one ... Foer also has a knack for finding the aptly revealing quote from a Silicon Valley executive; this is a book interested in petard-hoisting. World Without Mind becomes a little too preoccupied with journalism and creativity, particularly in its latter sections. The effect of certain technology on media can be profound and frightening. But it is hardly the sum of the changes the digital world has wrought ... Some may also find his unifying theories? a little too grand...But he mostly and persistently, with the zealotry of the companies he derides, builds a strong philosophical case.
