Semiconductors are no longer inputs within the global economy — they are its defining constraint. As compute becomes the limiting factor, growth, power and innovation are increasingly determined by access to chips and the systems that produce them.
The Substrate Economy: Power, Compute and the Limits of Physics
Markets run on capital. Economies now run on compute — and compute runs on physics
Markets still speak in capital. But beneath the surface, a deeper system is emerging — one defined by compute and physical limits.
For decades, economic power was measured in capital allocation, labor efficiency.and financial leverage. That model is breaking down. Today, the true constraint is neither money nor demand, but compute — and the physical systems that enable it. Semiconductors, energy grids and advanced manufacturing are no longer supporting layers of the economy; they are the foundation. What looks like a technology cycle is, in reality, a structural shift toward a world where growth is governed not by financial abstraction, but by the limits of physics itself.
The semiconductor industry is not a competitive landscape but a hierarchy of control. From design to fabrication to acceleration, value concentrates in the layers that define, constrain and allocate compute across the global economy.
Artificial intelligence is no longer scaling like software. As compute demand explodes, the real bottleneck is shifting toward electricity, grids, and physical infrastructure. The AI economy is becoming increasingly industrial — governed not only by algorithms, but by energy availability itself.
Artificial intelligence is pushing computing beyond the practical limits of electricity alone. As communication becomes the defining challenge of modern compute, integrated photonics may reshape the architecture of computing itself—using light to move information faster, more efficiently and with less energy.
