Limits to Growth (1972)
artifact
Economists mocked this 1972 book for 50 years, and it turned out to be the most accurate forecast we have.
Who they are
A landmark 1972 book by a team of MIT researchers, commissioned by the Club of Rome.
What they do
In the engine's read, it's the best long-range model of civilization's trajectory ever made.
How it works
Written by Donella and Dennis Meadows, Jorgen Randers, and William Behrens using MIT's World3 computer model, it sold 30 million copies and laid out 12 possible scenarios (not a single prediction); economists dismissed it for decades, but later checks by Turner in 2008 and Herrington in 2020 found its projections held up.
Why it matters
A book everyone dismissed quietly proved to be right about where the world is heading.
The engine's record — word for word
The 30-million-copy book. Donella Meadows, Dennis Meadows, Jorgen Randers, William Behrens III. Commissioned by Club of Rome, modeled at MIT using World3 system dynamics. 12 scenarios, not one prediction. 50-year empirical track record: most accurate macro-historical model ever produced. Dismissed by economists for decades. Vindicated by Turner (2008) and Herrington (2020).
