In August 2022, President Biden signed the CHIPS and Science Act, allocating $52.7 billion to reshore semiconductor manufacturing. The logic was compelling: Taiwan produces over 90% of the world's most advanced chips, and a single earthquake or Chinese blockade could cripple the global economy. Money would fix this. It didn't. TSMC's Arizona fab, announced in 2020 with a $12 billion price tag, ballooned to over $65 billion for three planned facilities. The first fab, targeting 4-nanometer chips, was originally slated for 2024 production but slipped to late 2025. The problem wasn't funding — it was everything money can't instantly buy. TSMC discovered that Arizona lacked the deep bench of process engineers that Hsinchu had cultivated over 37 years. A single advanced fab requires roughly ...
Popular framing: America just needs to spend enough money and it can rebuild any industry it wants.
Structural analysis: Capability is a stock built by decades of inflow, not a flow that can be purchased. Engineer pipelines, supplier clusters, and tacit process knowledge have long delay times, and the binding constraint on a fab is not capex but the depth of the surrounding ecosystem. Money buys the building; the harvest is years away.
The popular framing treats semiconductor manufacturing as a decomposable problem where money solves a resource deficit. The structural reality is that it's an interdependent sociotechnical system where the constraints are stocks built over decades — tacit knowledge, institutional trust, supplier density — that cannot be flow-injected on policy timescales. This gap matters because it sets false expectations for both timelines and costs, making political backlash against the policy likely before the long-horizon investment pays off, potentially triggering premature withdrawal and wasting the sunk capital.
