🧠 The Semiconductor Primer

Objective: Understand the "Oil of the 21st Century." This is the most complex supply chain in human history, powering everything from toasters to LLMs.

The Investment Thesis (The Why)

• The Silicon Cycle: We are entering a new "Super Cycle" driven by AI, distinct from the traditional PC/Smartphone cycles.
• Digital Sovereignty: Nations are subsidizing domestic production (CHIPS Act, EU Chips Act) to de-risk supply chains, creating a CapEx boom.
• Complexity Moats: Moore's Law is slowing, making advanced packaging and specialized architecture (GPUs, ASICs) the new drivers of performance.
