Dimensional Rotation
The structural pattern by which every sustained scaling law, upon encountering a physical limit on one axis, rotates onto a new axis rather than terminating — the semiconductor industry's most transferable lesson for the AI transition.
In 2003, Intel cancelled the Tejas processor. The chip had been designed to run at clock speeds exceeding four gigahertz, but the heat generated exceeded what any practical cooling solution could dissipate. The cancellation marked the moment when one dimension of Moore's Law — the steady increase in clock speed — hit a physical wall. The industry's response was not to abandon the trajectory. It was to rotate. Instead of faster processors, the industry built wider ones: multi-core architectures placed two, then four, then eight, then dozens of processing units on a single chip, each running at moderate clock speeds. Total computational throughput continued to increase roughly on Moore's Law's schedule, but the dimension of growth had changed. Speed gave way to parallelism. The curve had hit a wall on one axis and rotated onto another.
