Chris's masterpiece breaks down the AI investment logic by analyzing the industry chain step by step. The book centers around the 'five-layer industry chain' framework, starting from the foundational energy layer (nuclear power, natural gas, power grids) and moving upward through semiconductors, hardware infrastructure, cloud and data centers, all the way to large models and application layers. It provides an in-depth analysis of the competitive landscape, moats, and valuation logic of over 80 companies, offering actionable investment frameworks for each layer. It also focuses on risk management frameworks, investment playbooks, and long-term perspectives to help readers identify bubbles and turning points in cycles. Definitely worth a read!
