That's because the image of a Luddite is a thought terminating cliche. It's something specifically designed to prevent you from questioning technology by terminating any thought about the impacts of technology.
That's why I like to regularly remind people that the Luddites weren't just about smashing things because they liked smashy smashy, the premise was that the increases in productivity from machinery should benefit humanity and not only the owning class, because of the effects on employment.
The Luddites were having exactly the same argument we're having now, and as it turns out, they were right. Also, the side argument is the same now as it was then, except then they were arguing about steam engines burning coal, and we're now arguing about natural gas turbines.
When someone says Luddite, say fuck yeah! Here's to the fucking Luddites!
