The Map of AI Book
Summary
The "Map of AI" has expanded to nine layers, reflecting a "second computing revolution" where AI rebuilds the computer, rather than merely extending the web. New structural layers include the "agentic harness" for production usability and "governance" for paced frontier capability release. This transformation drives unprecedented CapEx, projected to reach \$1.04 trillion in 2026, potentially \$1.10–1.15T, with the Big Four (Amazon, Alphabet, Microsoft, Meta) accounting for \$725B. Demand is unconstrained, but supply is physically bound across all layers, from HBM4 memory (sold out through 2027) to lithography. Hyperscalers are evolving into utilities, securing massive power deals. Key business models include vertical integration (Google), horizontal dominance (NVIDIA), and flywheel effects (SpaceX), alongside niche players owning two adjacent layers. Geopolitically, China is building a parallel indigenous stack, while governance of frontier model releases impacts open-source development.
Key takeaway
For Directors of AI/ML and CTOs evaluating long-term infrastructure investments, recognize that AI represents a fundamental computer-rebuild cycle, not a typical cloud spending spree. Your strategy must account for pervasive supply constraints across the nine-layer stack, from HBM to power. Prioritize securing compute capacity and consider vertical or adjacent-layer ownership models. Be prepared for hyperscalers to function as utilities and for agentic enterprise to become the standard, leveraging protocols like MCP and AGENTS.md.
Key insights
The AI revolution is a fundamental rebuilding of computing infrastructure, not merely an extension of the web.
Principles
- AI demand is unconstrained, but supply is physically bound across all layers.
- The agent is becoming the computer, shifting from deterministic to probabilistic operation.
- Capital's role shifts from accelerator to allocator when physics binds.
In practice
- Focus on owning two adjacent layers in the AI stack for competitive advantage.
- Monitor HBM contract prices as a key indicator of market reality.
- Prepare for agentic enterprise becoming default, using MCP and AGENTS.md.
