Strategic Choices
Breadth vs. Depth
Breadth: Develop many technologies moderately
Depth: Master few technologies completely
Lingao approach: Focus on key enabling technologies first
Military vs. Economic
Military: Immediate security, but consumes resources
Economic: Long-term strength, but vulnerable short-term
Lingao approach: Balance both, minimum viable military
