Every age has a theory of rising and falling, of growth and decay, of bloom and wilt: a theory of nature. Every age also has a theory about the past and the present, of what was and what is, a notion of time: a theory of history. Theories of history used to be supernatural: the divine ruled time; the hand of God, a special providence, lay behind the fall of each sparrow. If the present differed from the past, it was usually worse: supernatural theories of history tend to involve decline, a fall from grace, the loss of God’s favor, corruption. Beginning in the eighteenth century, as the intellectual historian Dorothy Ross once pointed out, theories of history became secular; then they started something new—historicism, the idea “that all events in historical time can be explained by prior events in historical time.” Things began looking up. First, there was that, then there was this, and this is better than that. The eighteenth century embraced the idea of progress; the nineteenth century had evolution; the twentieth century had growth and then innovation. Our era has disruption, which, despite its futurism, is atavistic. It’s a theory of history founded on a profound anxiety about financial collapse, an apocalyptic fear of global devastation, and shaky evidence.
Most big ideas have loud critics. Not disruption. Disruptive innovation as the explanation for how change happens has been subject to little serious criticism, partly because it’s headlong, while critical inquiry is unhurried; partly because disrupters ridicule doubters by charging them with fogyism, as if to criticize a theory of change were identical to decrying change; and partly because, in its modern usage, innovation is the idea of progress jammed into a criticism-proof jack-in-the-box.”
