Prompt

If the transistor had been invented in 1920 instead of 1947, trace the likely technological, economic, and geopolitical implications through 1980. Be specific about second and third-order effects. Consider: How would this affect WWII? The Cold War? The space race? Consumer electronics? The structure of major economies? Which countries would benefit most? What technologies would emerge earlier, and what unexpected consequences might follow?
