The name comes from the Luddites, skilled English textile workers who in the early nineteenth century smashed the mechanised looms that were eroding their trade. They were not irrational, and they were not wrong about their own livelihoods: the machines really did take their jobs. The fallacy is not in noticing the loss. It is in the conclusion drawn from it — that the work itself would vanish, leaving fewer ways for people to earn a living. The amount of work in an economy is not a fixed quantity to be divided up and slowly eaten by machines.
What actually happens is harder to see while it is happening. A technology that destroys one category of work tends to lower the cost of something, and cheaper things get used in ways nobody anticipated. The mechanical loom collapsed the price of cloth, which expanded the clothing trade, which created tailors, merchants, and machine-builders who had not existed before. The displaced weaver could see the loom on the factory floor. He could not see the jobs that did not yet have names.
The fallacy is worth naming carefully, because invoking it can curdle into a way of dismissing real suffering. The historical record is consistent on the long run and brutal on the short one. Transitions have lifted total employment and living standards while leaving identifiable people — the weavers, the typesetters, the switchboard operators — to absorb the cost personally, often without recompense. To call the worry a fallacy is to make a claim about aggregates and decades, not about whether a particular person's fear is justified. Both things are true at once.
For the present moment, the fallacy cuts in an unexpected direction. The case that AI is different this time rests largely on speed — that the gap between destruction and recovery may be too compressed for the usual reabsorption to work the way it has before. That is a serious argument, and it is not answered by pointing at the Luddites. The honest position is to hold the pattern and the doubt together: history strongly suggests the work will not disappear, and history offers no comfort whatsoever to the person whose particular work disappears next year.
