Historical Counterfactual Analysis
If the transistor had been invented in 1920 instead of 1947, trace the likely technological, economic, and geopolitical implications through…
Excellent question. Shifting the invention of the transistor from 1947 to 1920 is a profound "Great Divergence" scenario. A working, mass-producible transistor in 1920 would trigger a cascade of acceleration, fundamentally rewriting the 20th century. Here’s a trace of the implications through 1980.Read the full answer
If the Transistor Had Been Invented in 1920: A Counterfactual Trajectory to 1980 Preconditions and plausibility By 1920, Karl Braun's cathode ray tube (1897) and Greenleaf Pickard's silicon crystal detector (1906) had already demonstrated semiconductor properties. Quantum theory was nascent (Planck, Bohr).Read the full answer
