Historical Counterfactual Analysis
If the transistor had been invented in 1920 instead of 1947, trace the likely technological, economic, and geopolitical implications through…
The Point of Divergence: 1920 To make this scenario plausible, we assume that Julius Lilienfeld’s theoretical patents for the field-effect transistor (FET) were accompanied by a breakthrough in materials science—specifically, the purification of germanium or silicon—allowing practical manufacturing by a major player…Read the full answer
The invention of the transistor in 1920 instead of 1947 would have profoundly accelerated technological, economic, and geopolitical developments by 1980. Below is a detailed breakdown of the likely implications: Technological Implications Earlier Miniaturization of Electronics Vacuum tubes, which dominated early…Read the full answer
