AI Is a 5-Layer Cake

Jensen Huang frames AI as a five-layer stack: energy, chips, infrastructure, models, and applications. Every AI application depends on all layers beneath it. The global buildout of this stack — chip factories, data centers, AI factories — represents what may become the largest infrastructure investment in human history, with trillions of dollars still to be spent. Beyond technical roles, the buildout demands large numbers of skilled trades workers. On the productivity side, Huang argues AI augments rather than replaces workers, using radiology as an example where AI handling routine tasks allows professionals to focus on higher-value work, ultimately expanding capacity and employment.
