Historical Counterfactual Analysis
If the transistor had been invented in 1920 instead of 1947, trace the likely technological, economic, and geopolitical implications through…
Premise: A functional solid-state transistor (germanium point-contact or junction) is demonstrated in 1920, with steady refinement through the interwar years. Vacuum tubes are not immediately displaced, but by the early 1930s transistors are reliable enough for niche military and telecom use, and by the late 1930s they…Read the full answer
Alternate‑history “transistor‑1920” timeline – technological, economic and geopolitical ripples through 1980 Below is a decade‑by‑decade sketch of the most plausible cascade that would have followed the appearance of a practical point‑contact transistor in 1920 (instead of 1947).Read the full answer
