In an essay in 1984—at the dawn of the personal computer era—the novelist Thomas Pynchon wondered if it was “O.K. to be a Luddite,” meaning someone who opposes technological progress. A better question today is whether it’s even possible. Technology is everywhere, and a recent headline at an Internet humor site perfectly captured how difficult it is to resist: “Luddite invents machine to destroy technology quicker.”

Like all good satire, the mock headline comes perilously close to the truth. Modern Luddites do indeed invent “machines”—in the form of computer viruses, cyberworms and other malware—to disrupt the technologies that trouble them. (Recent targets of suspected sabotage include the London Stock Exchange and a nuclear power plant in Iran.) Even off-the-grid extremists find technology irresistible. The Unabomber, Ted Kaczynski, attacked what he called the “industrial-technological system” with increasingly sophisticated mail bombs. Likewise, the cave-dwelling terrorist sometimes derided as “Osama bin Luddite” hijacked aviation technology to bring down skyscrapers.

For the rest of us, our uneasy protests against technology almost inevitably take technological form. We worry about whether violent computer games are warping our children, then decry them by tweet, text or Facebook post. We try to simplify our lives by shopping at the local farmers market—then haul our organic arugula home in a Prius. College students take out their earbuds to discuss how technology dominates their lives. But when a class ends, Loyola University of Chicago professor Steven E. Jones notes, their cellphones all come to life, screens glowing in front of their faces, “and they migrate across the lawns like giant schools of cyborg jellyfish.”

That’s when he turns on his phone, too.

The word “Luddite,” handed down from a British industrial protest that began 200 years ago this month, turns up in our daily language in ways that sugges...
