TL;DR
A November 3, 2026, article from ThorstenMeyerAI.com uses agriculture’s long decline in employment share to examine how technology can reshape work. It reports that about 1.5% of U.S. workers farm today, compared with an estimated 73.7% in 1800, while stressing that this change took generations and does not establish how quickly AI will affect other sectors.
ThorstenMeyerAI.com published an account on November 3, 2026, tracing how farming went from employing most U.S. workers to about 1.5% today, and using that history to frame questions about AI and future work. The article’s data describe a centuries-long transformation: labor’s share fell as tools, fertilizer and improved crop varieties helped raise agricultural output.
The article cites economic historian Stanley Lebergott’s estimate, later published by the U.S. Census Bureau, that about 1.4 million of 1.9 million U.S. workers were employed in agriculture in 1800, or 73.7%. The estimate covers workers aged 10 and older and includes about 530,000 enslaved people. Figures before 1840 are estimates rather than census counts, and the same series puts the agricultural share even higher in 1810. The article therefore describes the 1800 figure as roughly three in four, rather than a precise census result.
It presents agricultural change as a sequence, not a single breakthrough. A steel plough associated with John Deere dates to 1837; the article also points to the development of synthetic ammonia fertilizer in the early 20th century and the spread of high-yield, short-straw wheat in the 1960s. Citing Indian government statistics, it says the wheat harvest rose from 12.3 million tonnes in 1964–65 to 26.4 million tonnes in 1971–72. The comparison uses the year before the 1965–66 drought, when production fell to 10.4 million tonnes.
The account says U.S. farm employment continued to rise in absolute numbers until about 1910, reaching an estimated 11.8 million workers, even as agriculture’s share of the workforce declined. It also cites a German reconstruction in which farming’s share fell from 43% in 1882 to 25% in 1939, while the number of farm workers remained between 8 million and 10 million. Those examples distinguish a shrinking share of work from an immediate fall in the number of people employed.
What Farm History Shows About Automation
Agriculture is a useful historical comparison because its workforce share has fallen sharply while food production has grown. The source reports that the world’s cereal harvest increased 4.2-fold from 1961, compared with population growth of 2.7-fold over that period. It also says U.S. farm output in 2023 was nearly three times its 1948 level, with only a small rise in total inputs. These figures challenge the idea that fewer farm workers necessarily mean less food, though they do not by themselves explain every cause of higher output.
The history matters to workers and businesses considering AI because it shows that technology-driven changes in employment can unfold alongside rising output and new patterns of work. But agriculture is not a timetable for AI adoption. The source’s author characterizes the possibility that automation could affect up to 90% of a sector within a decade or a few decades as a thesis, not an established finding. The farming record supports discussion of long-run change; it cannot confirm the scale, pace or employment effects of AI in other industries.
The global picture is also uneven. The article cites an International Labour Organization estimate of 928 million people working in agriculture in 2025, about one in four workers worldwide. It gives agriculture’s share as 43% of workers in India, compared with about 1.5% in the United States and about 1% in Germany. That gap suggests mechanization and economic change have not reached every country or labor market in the same way.

How Agricultural Employment Fell
The article sets the U.S. experience alongside historical estimates for other countries. It cites a reconstruction that puts Japan’s primary-sector employment, including farming, forestry and fishing, at about 85% in 1872. For Germany, an economic historian’s reconstruction puts the primary sector at 56.7% in 1849; the first official occupational census cited in the article recorded 43.4% in agriculture and forestry in 1882. The source cautions that this count underrepresented women working on family farms.
For China, the article says 83.5% of employed people were in the primary sector when the national statistical series began in 1952. India’s 1951 census counted cultivators and agricultural laborers as 69.7% of workers. The figures come from different dates and methods, and should not be treated as perfectly comparable measures. They show, in broad terms, how much employment was tied to land-based production in societies before later shifts toward industry and services.
The underlying constraint, as the article explains it, was the amount of food a farm household could produce using human and animal power, hand tools and available land. Better machinery helped change that limit, while fertilizer and improved seeds raised yields. The account mentions Fritz Haber’s 1908 patent on ammonia synthesis and the later industrial production of fertilizer, alongside crop breeding that produced wheat able to support more grain without falling over. No single development accounts for the full transformation.
“Farming shows a whole sector can be emptied of human hands. It also shows that it took about 200 years in America.”
— Thorsten Meyer, author of the November 3 article
Limits of the AI Comparison
The source provides historical agricultural data and an argument for considering it alongside AI, but it does not present evidence establishing how many jobs AI will change or eliminate. It gives no defined sector, measurement method or baseline for the claim that automation could affect up to 90% of a sector. The phrase is the author’s projection, not a measured outcome.
Some historical figures are estimates or reconstructions, and the country figures refer to different years, categories and data sources. The article also does not specify what “emptied of human hands” means in practice: agriculture still employs 928 million people worldwide by its cited 2025 estimate. The pace, distribution and consequences of future changes in farming and other work remain uncertain.
The Next Test: Work Beyond Farms
The source presents this article as Episode 2 of “Work After Work”, an installment in a series about how the economy is built. Its next episode is described as covering the machinery that followed early agricultural tools, including reapers, threshers and tractors. That material may add detail to the farm history, but it would not by itself establish AI’s likely employment effects.
For readers tracking the wider AI question, the next useful evidence will be observed changes in hiring, tasks, output and wages across specific industries—not an assumed parallel with agriculture. The source does not provide a date or forecast for those changes. Its current contribution is a historical comparison and a clearly labeled hypothesis, with the actual scale and timing of AI’s effect on work still to be determined.
Key Questions
How much of the U.S. workforce farmed in 1800?
The article cites an estimate that 73.7% of the U.S. labor force worked in agriculture in 1800, or about three in four. The figure is an estimate, not a census count, and includes enslaved workers.
How many people work in agriculture worldwide?
The article cites an ILO estimate of 928 million people in 2025, about one in four workers worldwide. It reports much higher agricultural employment shares in India than in the United States or Germany.
Does the article show that AI will replace most workers?
No. It uses farming as a historical comparison, but the author’s suggestion that automation could affect up to 90% of a sector is explicitly labeled a thesis, not a fact. The article does not establish AI’s future job impact.
Why did farm employment fall as food production grew?
The account points to several changes over time, including improved tools, synthetic fertilizer and higher-yield crop varieties. It reports rising agricultural output alongside a falling share of workers in farming, but does not attribute the shift to one invention alone.
