Is the Industrial Revolution a good precedent for explosive growth today?
For engineers building or investing in AI systems, this challenges the narrative that AI will inevitably produce explosive economic growth comparable to the Industrial Revolution. The argument suggests that claims of 20%+ annual growth from AI are not supported by the historical analogy often used to justify them—a more realistic benchmark from an IR-style acceleration would be growth around 2.8% per year in frontier economies.

In pre-Industrial Revolution UK (1252–1652), annual growth rates exceeding 10× the long-run compound average occurred in roughly 46% of years, making such accelerations relatively common experiences rather than unprecedented events.
When measured in terms of standard deviations from normal variation, an Industrial Revolution-style acceleration today would bring frontier economy growth to approximately 2.8% per year, not the 10× or 20%+ rates some predict from AI.
The key difference is that a 10× acceleration in the 1700s meant good years becoming more common (rates already experienced), while a 10× acceleration today would require qualitatively different economic dynamics falling several standard deviations outside current norms.
