Taiwan Makes the Chips. That Makes It the Most Important Place in AI

No place matters more to artificial intelligence than Taiwan. The overwhelming majority of the world's most advanced semiconductors, including nearly all leading-edge AI accelerators, are manufactured on the island, and there is no near-term substitute.

The manufacturing concentration:

TSMC is the world's dominant contract chip manufacturer at advanced nodes. The companies that design AI accelerators do not build them; they send designs to Taiwan.

This concentration developed over decades through relentless process improvement, enormous capital investment and accumulated manufacturing expertise that competitors have struggled to match. Producing chips at leading-edge nodes requires not only the right equipment but yield knowledge acquired through experience, which cannot be bought.

The wider Taiwanese ecosystem extends well beyond one company. Advanced packaging, which has become critical as chips are increasingly built from multiple stacked components, is substantially concentrated in Taiwan, and packaging capacity has repeatedly been a bottleneck on accelerator supply. Server assembly is another Taiwanese specialty: much of the world's AI server hardware is designed and built by Taiwanese firms.

The geopolitical dimension:

This concentration is the central vulnerability of the global AI industry. Any serious disruption around Taiwan, whether military, natural or logistical, would halt production of the chips on which the entire sector depends.

That reality drives policy worldwide. Subsidy programmes in the United States, Europe, Japan and elsewhere aim to build domestic advanced manufacturing capacity, and Taiwanese firms have established fabrication plants abroad in response to both incentives and customer pressure.

Diversification is real but partial. New facilities take years to build and longer to reach comparable yields, and the most advanced production, along with the deepest engineering base, remains in Taiwan.

Domestic AI development:

Taiwan's AI activity beyond hardware is smaller but real. Research institutions work on machine learning, and government programmes support AI applications in manufacturing, healthcare and smart cities.

The natural domestic application is semiconductor manufacturing itself. Yield optimisation, defect detection and process control on production lines costing tens of billions are among the highest-value machine learning problems anywhere, and Taiwanese firms are sophisticated users.

Taiwan has also invested in traditional Chinese language models, partly for practical utility and partly to ensure the linguistic and cultural framing of models serving its population is not determined elsewhere.

Constraints:

Energy is a genuine problem. Semiconductor manufacturing is extraordinarily power-intensive, Taiwan imports most of its energy, and its electricity policy has been politically contested. Water is also a constraint: chip fabrication uses vast quantities, and droughts have previously forced difficult allocation decisions.

Talent shortages are acute. The semiconductor sector absorbs a large share of the country's engineering graduates, and competition for experienced process engineers is intense, including from foreign firms recruiting aggressively.

Demographics compound this, with one of the world's lowest birth rates shrinking the future workforce.

The outlook:

Taiwan's position is simultaneously its greatest asset and its greatest exposure. The concentration of manufacturing gives the island economic significance far beyond its size and makes it central to the calculations of every major power.

For the AI industry, the practical fact is unchanged: for the foreseeable future, the chips come from Taiwan.
