The Luddites were a group of English textile workers and weavers in the 19th century who destroyed weaving machinery as a form of protest. The group was protesting the use of machinery in a "fraudulent and deceitful manner" to get around standard labor practices. Luddites feared that the time spent learning the skills of their craft would go to waste as machines would replace their role in the industry.
It is a misconception that the Luddites protested against the machinery itself in an attempt to halt the progress of technology. Over time, however, the term has come to mean one opposed to industrialization, automation, computerization, or new technologies in general.
The Luddite movement began in Nottingham and culminated in a region-wide rebellion that lasted from 1811 to 1816. Mill owners took to shooting protesters and eventually the movement was suppressed with military force.
The growing opposition to Artificial Intelligence computers has also been labeled as Luddite in nature.
The opposition to fusion is likewise called Luddite. In truth much of the opposition is economically based by those that are making and selling the replaced technologies. So the truest sense they are Luddites.
