Nationwide AI Ecosystem Design

Imagine you are a senior policy advisor tasked with building a nationwide AI ecosystem that can accelerate diversification across energy, manufacturing, services, and governance. Compare three viable models for how a country can organize funding, data governance, talent pipelines, ethics and risk management, public-private partnerships, and international collaboration. For each model, outline a phased implementation plan with milestones, key stakeholders, resource needs, and measurable outcomes over a multi-year horizon. Conclude with a recommended approach and a clear rationale.
