What happens when a civilisation becomes dependent on a single, irreplaceable input?

In 1177 BC: The Year Civilization Collapsed, Eric H. Cline describes how the disruption of tin supply chains contributed to the collapse of Bronze Age economies. Tin was scarce, difficult to transport, and essential. When supply faltered, entire systems built upon it began to unravel.

Today, the global technology ecosystem faces a very different — yet curiously familiar — constraint.

Artificial intelligence, cloud infrastructure, and advanced computing are increasingly reliant on a narrow segment of the semiconductor supply chain, centred on leading-edge fabrication. In particular, TSMC occupies a critical position as the primary manufacturer of the most advanced logic chips.

As demand for AI compute accelerates, capacity at the leading edge is becoming a binding constraint. Capital expenditure is rising, timelines are fixed by physics, and supply cannot be expanded quickly enough to meet demand in the near term.

This note explores the parallels between ancient supply-chain fragility and today’s semiconductor bottlenecks — and considers what this may mean for competitive positioning across the technology landscape.
