Nvidia chief Jensen Huang used a G20 tech summit to push governments to spend big on AI and to ease off regulation — good news for chipmakers and data-center builders, worrying for anyone hoping for tighter AI rules.

• Nvidia alone will spend close to $1 trillion on US infrastructure this year.
• Huang called AI a basic utility like water and power, and said every country needs its own AI infrastructure to support its economy.
• His warning to governments: the worst outcome is being left behind, so fear of AI should not drive policy.
• The US hosted the summit and is promoting the "Carolina Principles," which urge countries not to set up separate AI regulators and to let governments and companies test new technology together.
• Huang said rules should target real, concrete harms rather than theoretical ones, and that companies — not officials — should carry responsibility for product safety.

Outlook: Expect more countries to announce national AI build-outs while pressure grows to keep AI rules light.
