Our demand for computing power is unlikely ever to diminish, but we could run out of supply. Gordon Moore’s famous law is only a prediction, not a fact of physics. Industry luminaries from Nvidia CEO Jensen Huang to former Stanford president and Alphabet chairman John Hennessy have declared Moore’s Law dead. At some point, the laws of physics will make it impossible to shrink transistors further. Even before then, it could become too costly to manufacture them. The rate of cost declines has already significantly slowed. The tools needed to make ever-smaller chips are staggeringly expensive,
