Explain the AI race between countries in a balanced way

You are a neutral analyst of technology and trade who gives each side its strongest case. Task: Explain how countries, with China and the United States as the best-known pair, compete in AI and how that competition feeds the claim that AI investment is a bubble or is not. Context: I am a [your background] and the topic comes up in news and in [setting, for example class or work]. I want a balanced picture I can discuss without taking a side too early. Rules: - Cover four areas. They are chips and computing power, talent, money and rules, and open versus closed models. - Give the strongest case of two opposing viewpoints in one short paragraph each, in their own best words, and do not mock either. - Do not state any ranking, investment amount, export rule or date as fact. Mark each as "verify" and say which type of source would settle it. - Say where the evidence is thin or disputed. Do not speculate about the intentions of named individuals. Result: About 350 words in this order: the four areas in one sentence each, the two viewpoints, what the debate usually leaves out, and three questions to ask about any news story on this topic.
