Scaling Shadows
The thermodynamic companions of every scaling law — the quantities that grow alongside the desired gain, in the opposite direction of value — which require the same engineering rigor as the gains themselves and whose management, not the scaling itself, was the semiconductor industry's greatest achievement.
Every engineer who has worked with power systems knows the concept of waste heat. A motor converts electrical energy into mechanical motion, but not all energy becomes motion. Some becomes heat. The heat is not a malfunction — it is a thermodynamic consequence of the conversion. The motor works precisely as designed. The heat is the shadow of the work. Moore's Law had shadows from the beginning: as transistor density scaled upward, heat dissipation scaled with it; as clock speeds increased, power consumption increased; as feature sizes shrank, leakage current grew. Each shadow was a quantity that scaled alongside the desired growth, in the opposite direction of value.

The semiconductor industry did not treat shadows as problems to be solved and forgotten. It treated them as permanent companions of the scaling trajectory. Each generation required new accounting of shadow costs, new engineering
