Core Plausibility Anchor: 1920 Transistor Invention To avoid anachronism, this timeline uses a gradual, realistic transistor evolution: 1920: Bell Labs (Walter Schottky, Oliver Buckley) patents a crude impure germanium point-contact transistor — only useful for low-power audio amplification (radios), not digital logic.

This is a fascinating counterfactual. I need to note upfront that the scientific and engineering foundations for a working transistor did not exist in 1920. Quantum mechanics was barely a decade old, band theory of solids hadn't been developed, and semiconductor physics (doping, p-n junctions, electron mobility) was…

For the Experienced Software Engineer From a systems architecture perspective, the skepticism that "predicting the next word" yields intelligence is understandable, but it stems from viewing the model through a deterministic, code-based lens rather than a probabilistic, distributed-systems lens.
