If data is the new oil, then semiconductors are the pipelines, refineries, and engines all rolled into one.

Over the last few years, the geopolitical landscape has been radically reshaped by one central realization: the country that controls the most advanced silicon controls the future of technology, from consumer electronics to advanced military AI.

The Chokepoint: TSMC and Taiwan

The vast majority of the world’s most advanced logic chips (under 5nm) are manufactured by a single company: Taiwan Semiconductor Manufacturing Company (TSMC). This concentration of manufacturing capability on an island with complex geopolitical status is the single most critical chokepoint in the global tech supply chain.

When I was at the HPAIR Harvard Conference recently, this was a recurring theme in discussions about global risk. The tech industry is built on a precarious foundation of highly specialized, geographically concentrated nodes.

The Push for “Onshoring”

We are now seeing an unprecedented push for “onshoring” or “friendshoring” semiconductor manufacturing.

  • The US CHIPS Act: Pumping billions into domestic fab construction (Intel in Ohio, TSMC in Arizona).
  • Europe: Aiming to double its global market share in chip production by 2030.
  • India: India’s own semiconductor mission is aggressively courting fab investments to build an ecosystem from the ground up, moving beyond just chip design into actual manufacturing and assembly/testing (ATMP).

However, building a fab isn’t just about money. It requires highly specialized talent, a massive supply of ultra-pure water, and an ecosystem of suppliers (like ASML for lithography machines). It takes years to bring a new fab online.

The tech world is currently holding its breath. We are transitioning from a hyper-globalized, heavily optimized supply chain to a more fragmented, resilient, but potentially much more expensive one. The geopolitical implications of this shift will define the next decade of technology development.
