A November 3, 2026, article from Thorsten Meyer AI uses agriculture to examine how work changes when productivity rises. It reports that about 73.7% of the U.S. labor force worked in agriculture in 1800, compared with about 1.5% today, while stressing that the change took generations and that farming still employs an estimated 928 million people worldwide. The article’s suggestion that AI could automate most work within decades is a forecast, not an established finding.
Thorsten Meyer AI published an episode on November 3, 2026, examining how farming went from employing most U.S. workers to about 1.5% of the workforce and what that long shift may suggest about artificial intelligence. The episode presents agriculture as a case study in labor displacement and rising productivity, while acknowledging that its proposed timeline for AI-driven change is a thesis, not a confirmed outcome.
The episode cites economic historian Stanley Lebergott’s estimate that 1.4 million of 1.9 million U.S. workers in 1800 were employed in agriculture, or 73.7%. The underlying figures for years before 1840 are estimates rather than census counts, and the labor-force tally includes about 530,000 enslaved people. The source therefore describes the early share as roughly three in four, rather than treating the percentage as an exact count.
The reduction in farm labor took place over centuries and through successive changes, not a single invention. The episode points to improved equipment, including a steel plough developed by John Deere in 1837, and to advances in crop breeding and fertilizer. It cites the introduction of short-straw wheat in India and Pakistan in the mid-1960s, and Indian statistics showing the wheat harvest increased from 12.3 million tonnes in 1964–65 to 26.4 million tonnes in 1971–72.
The article says the U.S. number of farm workers continued to grow until about 1910, reaching 11.8 million, even as farming’s share of the workforce declined. It gives an International Labour Organization estimate of 928 million agricultural workers worldwide in 2025, or about one in four workers. Agriculture’s employment share varies widely: the source gives 43% for India, about 1.5% for the United States and about 1% for Germany.
Farm Productivity and Labor’s Long Shift
The agricultural record complicates the idea that fewer workers in a sector automatically mean less production. The episode reports that global cereal harvests grew 4.2-fold from 1961, while the world population grew 2.7-fold over the same 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 support the point that productivity can increase while employment falls, though they do not establish that every worker displaced from farming found secure or comparable work elsewhere.
That distinction matters as businesses adopt AI tools. Agriculture offers evidence that technological change can reshape a sector’s labor needs over an extended period, but it does not give a reliable timetable for changes in office, service or industrial jobs. The technologies, tasks, institutions and labor protections differ. The episode’s comparison is useful as a historical lens, not a prediction that AI will follow the same path.
The transition also remains uneven worldwide. An estimated 928 million people still work in agriculture, according to the source’s 2025 ILO figure. For workers and policymakers, the relevant questions include not just how many jobs a technology changes, but where new work appears, who can access it and how productivity gains are shared.

From Muscle Power to Modern Farming
In 1800, food production depended heavily on human and animal labor, tools and weather. The source argues that limited output per farm household meant a large share of the population had to work the land. It compares early U.S. figures with estimates from other countries: about 85% of workers in Japan’s primary sector in 1872, 83.5% in China’s primary sector in 1952, and 69.7% of Indian workers classified as cultivators or agricultural laborers in 1951. Those measures are not perfectly equivalent: some count the broader primary sector, which includes forestry and fishing, and several are reconstructions or estimates rather than census results.
Mechanization and biological innovation changed what farms could produce with fewer workers. The source points to the 1837 steel plough, later machinery, synthetic ammonia production following the Haber process, and crop breeding associated with the Green Revolution. For India, it records wheat output reaching 35.5 million tonnes in 1978–79 and a third advance estimate of 117.5 million tonnes for 2024–25. These examples show changes in output and technology; they do not, on their own, isolate how much each innovation caused employment to fall.
““My thesis, not a fact: automation could become a sector of up to 90% within a decade or a few decades.””

Limits of the AI Comparison
The episode does not specify which occupations or tasks its proposed 90% automation figure refers to, how that figure is calculated, or what evidence supports the suggested timeline of a decade or several decades. It should be read as the author’s thesis, not as a confirmed forecast. The source also does not establish that AI will displace workers at the same pace or through the same mechanisms as farm technology.
Some historical employment figures are estimates, reconstructions or counts with different definitions. For example, the source says early U.S. figures are estimates and that Germany’s 1882 census undercounted women who worked on family farms. The global 928 million figure is attributed to an ILO estimate for 2025, but the episode does not provide the underlying methodology in the supplied material. It remains unclear how future AI adoption will affect the number, quality and location of jobs, or how gains will be distributed.
The Next Episode on Mechanization
The source presents this installment as the second episode in a series about how the economy is built, and says the next episode will cover the role of mechanical reapers, threshers and tractors. That installment may add detail on the machinery side of agriculture’s labor shift. The broader AI comparison will require evidence about actual adoption, changes in tasks and employment, and outcomes for workers; the current episode provides a historical comparison rather than new labor-market data on AI.
Key Questions
How many Americans worked in agriculture in 1800?
The episode cites an estimate of 1.4 million out of 1.9 million workers, or 73.7%. The figures before 1840 are estimates, not census counts, and the total includes enslaved people.
How many people work in agriculture worldwide?
The source cites an ILO estimate of 928 million agricultural workers in 2025, about one in four workers worldwide.
Does the farming example prove AI will eliminate most jobs?
No. The episode uses agriculture as a historical comparison. Its suggestion that automation could affect up to 90% of a sector within a decade or a few decades is explicitly presented as the author’s thesis, not a fact.
Why did agricultural employment decline?
The source describes a long series of changes, including improved tools and machinery, fertilizer and crop breeding. These helped raise output per worker, although the episode does not quantify the separate effect of each innovation on employment.
