As NVIDIA rises and the world’s AI infrastructure relies on chips made in Taiwan, a critical question emerges: can the U.S. remain dominant without its tech ally?

Tech Desk — June 11, 2025:
In June 2025, NVIDIA overtook Microsoft to become the most valuable company in the world. A tech firm that once served gamers now designs the processors that power artificial intelligence systems—from ChatGPT to battlefield drones. But there’s a deeper story behind the market celebration: NVIDIA doesn’t manufacture its own chips. That job falls to TSMC—the Taiwan Semiconductor Manufacturing Company.
TSMC sits at the center of the global tech supply chain. Its cutting-edge chips power not just NVIDIA’s AI hardware but also Apple’s iPhones, AMD’s processors, and even advanced defense systems. In effect, the world’s digital future runs through a single island in the South China Sea.
The U.S. understands this. So does China. When former President Donald Trump moved to block advanced chip technology from reaching China, it wasn’t about trade—it was about survival in the AI race. Today, China faces a chip blockade: it has data scientists, money, and ambition, but no access to the tiny 5nm and 3nm chips needed to train powerful AI.
The result is a global standoff. The U.S. is pouring billions into reshoring semiconductor fabrication, trying to build its own version of TSMC in Arizona and elsewhere. Japan is doing the same. But TSMC’s expertise, built over decades, cannot be copied easily or quickly. In the meantime, the world still depends on Taiwan—and Taiwan knows it.
This dependence has created a new kind of geopolitical deterrent: the "Silicon Shield." If China attacks Taiwan, it doesn’t just trigger a military conflict—it breaks the global supply chain, plunging the world into technological chaos. This gives Taiwan strategic leverage. But it also makes the island a target and a pressure point in the new cold war between the U.S. and China.
And so the question hangs in the air: Can America stay on top without Taiwan’s silicon shield? If Taiwan falls—or even falters—the entire AI-driven infrastructure of American power may collapse with it.
In a world no longer divided by ideology but by access to chips, the balance of power may be measured not in armies, but in nanometers.
