Advanced semiconductors — particularly logic chips at the most recent process nodes and the extreme-ultraviolet lithography tools used to make them — have emerged as the defining contested resource of the decade. A small number of firms, most prominently TSMC in Taiwan and ASML in the Netherlands, sit at chokepoints no state can quickly replicate. This has turned chip supply into a matter treated by many governments as closer to nuclear materials than to ordinary trade.
Geography of the chokepoint
Taiwan's centrality to leading-edge fabrication is the most discussed feature of the landscape, with knock-on implications for cross-strait tensions that the wiki does not attempt to adjudicate. The United States responded with the CHIPS and Science Act (2022) and successive rounds of export controls restricting advanced chip and tool sales to specified jurisdictions; allied governments adopted broadly similar measures. The European Union and Japan launched their own industrial programs.
Compute as contested abundance
From the abundance perspective, chips are the physical substrate of Compute Abundance — the pillar that makes modern AI, simulation, and design-space search tractable. A world in which compute is politically rationed is a world in which other abundances (drug discovery, climate modeling, robotics) are partially rationed too. The policy debate is therefore not only about military advantage but about who gets to build what, when.
Responses and limits
Responses include on-shoring fabs (slow, expensive, and still dependent on global tool and materials supply chains), diversifying packaging and mature-node capacity, investing in alternative architectures, and — on the open side — open-source hardware and RISC-V ecosystems. None removes the chokepoint quickly; all change the shape of the graph. See Rare Earth Geopolitics for an adjacent chokepoint story and Military Innovation Crossovers for the dual-use dimension.
Open questions
Whether export controls slow rival capability development by years or merely months, whether on-shoring produces genuinely resilient supply or politically comfortable redundancy, and whether a crisis around Taiwan can be deterred by economic interdependence alone are all actively contested. Reasonable analysts disagree; the wiki flags the disagreement rather than resolving it.
