    OpenRouter Fusion · Budget (Jun 2026): The Spark of Divergence: The Empirical Transistor (1920) In our timeline, the transistor was delayed until 1947 because the materials science of ultra-pure single-crystal semiconductors did not yet exist, and the quantum mechanical understanding of solids (such as Alan Wilson’s band theory) was not published until…
