Summary
A gripping and well-researched narrative of how semiconductors became the linchpin of global power. Chris Miller connects the dots between military dominance, economic development, and the race for control over the world’s most advanced chips.
Key Insights
- Semiconductors are now the most strategic resource on Earth—more critical than oil.
- The U.S. maintained dominance not just by innovation, but by controlling key choke points in chip design and production.
- Taiwan’s TSMC is arguably the most important company in the world due to its advanced chip manufacturing capabilities.
- China is investing heavily to achieve self-sufficiency, but still faces steep technological hurdles.
- Modern warfare and economic competition are deeply intertwined with semiconductor supply chains.

My Review
Why This Book Matters
Chip War is a masterclass in understanding the 21st-century struggle for technological supremacy. It lays out how semiconductors—small pieces of silicon with billions of transistors—have become the backbone of modern society and military power.
The book doesn’t just explain how chips work; it reveals how they’ve reshaped geopolitics, economics, and warfare. It’s essential reading for anyone interested in global power dynamics, tech innovation, or national security.
Overview of the Conflict
The core argument: control over advanced semiconductors is equivalent to control over the future.
The U.S. historically led the field, but now faces rising competition from China and dependency on Taiwan. Miller highlights how critical companies like TSMC, ASML, Intel, and NVIDIA hold monopoly-level influence over global innovation and military strength.
Key Themes
- Choke Points in the Supply Chain: No single country controls the entire chip pipeline. ASML controls EUV lithography, TSMC leads fabrication, and the U.S. dominates EDA tools and chip design.
- Taiwan’s Strategic Vulnerability: If Taiwan were disrupted, the global economy would be severely impacted within weeks.
- China’s Ambitions: Massive subsidies, espionage attempts, and government-backed firms are part of China’s effort to catch up—but they’re still behind in fabrication and tooling.
- Military Implications: From drones to missiles to AI, modern weapons rely on high-end chips. Nations that fall behind in chip tech risk strategic irrelevance.
Personal Impact
Reading this book made me deeply aware of how invisible technology shapes real-world power. It reframed how I think about supply chains—not as economic trivia, but as battlegrounds of modern statecraft.
It also made me more mindful of how fragile innovation is when it depends on such a concentrated and geopolitically tense set of actors.
Practical Applications
- I now follow chip manufacturing news with much greater understanding (TSMC capacity, U.S. CHIPS Act, China sanctions, etc.).
- I started mapping out tech dependencies in products I work on or use.
- This book helped me better connect macroeconomic risks with day-to-day engineering, product strategy, and security discussions.
Final Verdict
Rating: 5/5
An urgent and eye-opening read. Chris Miller blends history, economics, and national security into a compelling narrative. If you’re in tech, policy, or global affairs, this is non-optional reading. It explains why chips matter—not just as tools, but as weapons, levers of influence, and the heart of modern civilization.
Action Items
- Track the development of advanced nodes and chip architectures beyond 3nm.
- Understand geopolitical risks in semiconductor supply chains, especially around Taiwan and China.
- Follow export control policies and domestic chip manufacturing incentives like the U.S. CHIPS Act.
- Explore the strategic roles of ASML (EUV), TSMC, NVIDIA, Intel, and Samsung.
- Assess the impact of chip access on national security and industrial competitiveness.
