The current 3x annual growth in AI compute is not easily accelerated and may be unsustainable. It is fundamentally constrained by the slowing of Moore's Law (1.4x), the fixed production rate of ASML's EUV machines for new fabs (1.2x), and the near-total absorption of leading-edge wafer capacity from other sectors (1.8x).

AI software models advance every few months, creating exponential demand. However, the hardware infrastructure like chip fabs operates on two-to-four-year development cycles. This timeline disconnect between software's rapid pace and hardware's slow build-out creates a persistent supply crunch that money alone cannot instantly solve.

The AI industry's growth constraint is a swinging pendulum. While power and data center space are the current bottlenecks (2024-25), the energy supply chain is diverse. By 2027, the bottleneck will revert to semiconductor manufacturing, as leading-edge fab capacity (e.g., TSMC, HBM memory) is highly concentrated and takes years to expand.

Nvidia CEO Jensen Huang states AI growth is constrained by much more than just chips. The entire physical supply chain—including land, power, construction workers, photonics, and connectors—is a bottleneck. This indicates the next wave of investment and risk will focus on these fundamental, non-digital infrastructure components.

The focus in AI has evolved from rapid software capability gains to the physical constraints of its adoption. The demand for compute power is expected to significantly outstrip supply, making infrastructure—not algorithms—the defining bottleneck for future growth.

The primary constraint on AI scaling isn't just semiconductor fabrication capacity. It's a series of dependent bottlenecks, from TSMC's fabs to the limited number of EUV machines from ASML, and even further down to ASML's own specialized suppliers for components like lenses and glass.

Author Chris Miller explains that the further down the supply chain you go (from hyperscalers to fabs like TSMC to equipment makers like ASML), the more skepticism there is about the true scale of AI demand. This "bullwhip effect" results in cautious capital expenditure, creating a manufacturing bottleneck for the AI industry.

Every layer of the AI supply chain is constrained, from energy and data centers to turbines, transformers, and rare earth minerals. This is a shift from software limitations to hard physical constraints. As a result, the price of intelligence may stop decreasing and could even rise.

The long-term ability to scale AI compute is not constrained by power or data centers, but by the production of advanced semiconductors. The ultimate chokepoint is ASML, the world's only manufacturer of EUV lithography tools, which can only produce just over 100 units annually by 2030.
