Analyzing Elon Musk's TeraFab — A step towards Tesla and SpaceX's partial vertical integration, or an unattainable dream?

Elon Musk's TeraFab project aims to produce AI logic chips and HBM memory, requiring trillions of dollars and hundreds of fabs, posing challenges in capital, equipment availability, and workforce expertise. The project's scale exceeds current industry capacity, with constraints in lithography tool supply and process technology development. TeraFab would need hundreds of thousands of construction workers and over 300,000 skilled employees, raising doubts about its feasibility. While ambitious, the project may serve as a step towards partial vertical integration for Musk's companies rather than a complete transformation of the semiconductor market.
