Washington underestimates China's AI chip progress — TSMC thesis inverted
- —A Foreign Affairs article by Eyck Freymann posits a Chinese soft-blockade scenario on Taiwan, arguing the US could theoretically destroy TSMC's fabs to deny China access to advanced chip capacity
- —Doomberg finds this framing revealing: if inner Washington believes TSMC is still the crown jewel China needs, it is wildly miscalculating how fast China is closing the AI semiconductor gap
- —Prior Doomberg pieces — Chip Shot (Apr 2024), Is the Chip War Already Lost (Dec 2024), On the Ascend (May 2025), Trump Card (Dec 2025) — consistently warned that Western analysts underestimate the pace of Chinese chip innovation
TSMC is at the center of a geopolitical inversion thesis: Washington assumes the fabs are leverage it holds over Beijing, but the argument here is that once China closes the AI chip gap, TSMC's facilities become leverage Beijing holds over Washington instead. If China's self-sufficiency timeline is materially shorter than consensus, TSMC's strategic moat is more fragile than its valuation implies
The core concern is that the Western semiconductor advantage is being eroded faster than markets or policymakers price in. China's AI chip trajectory — evidenced by Huawei's new architectures and accelerating domestic ecosystem — suggests the export-control strategy is losing effectiveness. The bear case is not a sudden shock but a slow-moving realisation that the moat has already been crossed
If Beijing waits for AI chip self-sufficiency before acting on Taiwan, the US loses its most potent deterrent. Foreign Affairs floating TSMC destruction as a US countermove signals there are no clean options left — only self-damaging ones. The strategic calculus flips once China no longer needs TSMC to lead in AI, making a Taiwan move both lower-cost and higher-reward for Beijing
