Among the most viable of all economic delusions is the belief that machines on net balance create unemployment. Let us turn to Adam Smith’s Wealth of Nations. The first chapter [...] is called “Of the division of labor,” and on the second page of this first chapter the author tells us that a workman unacquainted with the use of machinery employed in pin-making “could scarce make one pin a day, and certainly not twenty,” but with the use of this machinery he can make 4,800 pins a day. In the pin-making industry there was already, if machines merely throw men out of jobs, 99.98 percent unemployment. Arkwright invented his cotton-spinning machinery in 1760. At the time it was estimated that there were in England 5,200 spinners using spinning wheels, and 2,700 weavers - in all 7,900 persons engaged in the production of cotton textiles. The introduction of Arkwright’s invention was opposed on the ground that it threatened the livelihood of the workers, and the opposition had to be put down by force. Yet in 1787 [...] the number of persons actually involved in the spinning and weaving of cotton had risen from 7,900 to 320,000, an increase of 4,400 percent. [...] Technophobes will assert: “That may have been all very well in the past, but today conditions are fundamentally different; and now we simply cannot afford to develop any more labor-saving machines.” If it were indeed true that the introduction of labor-saving machinery is a cause of constantly mounting unemployment and misery, the logical conclusion to be drawn would be revolutionary, not only in the technical field but for our whole concept of civilization. Not only should we have to regard all further technical progress as a calamity; we should have to regard all past technical progress with equal horror. There is also an absolute sense in which machines may be said to have enormously increased the number of jobs. The population of the world today is four times as great as in the middle of the 18th century, before the Industrial Revolution had got well under way. Machines may be said to have given birth to this increased population; for without the machines, the world would not have been able to support it. Three out of every four of us, therefore, may be said to owe not only our jobs but our very lives to the machines.

[From “Economics in One Lesson”]

Hazlitt likely didn't even dream of people being replaced by algorithms.

The trick in the past has always been to invent new types of jobs to take advantage of the technological progress. We're out of tricks if one can automate highly sophisticated tasks.

The book quote provides a way for you to understand for how long this claim is made (with an exemple from the 18th century), and yet here we are.

_because_ of automation lowering car prices among other causes.
