Nvidia chief Jensen Huang used his first-ever post on X to highlight a new warning from the AI sector to US policymakers. The post shared an open letter backed by 25 companies, including Nvidia, Microsoft and Palantir, urging Washington not to make with artificial intelligence the kind of policy mistake that software narrowly avoided in the 1980s.

The central message is that heavy-handed limits on AI could damage the industry's growth and long-term competitiveness. By invoking the software debate from decades ago, the signatories appear to be arguing that overly restrictive rules can slow innovation at a pivotal moment for a fast-moving technology.

Huang's post also put a spotlight on a broader argument now shaping the global AI debate: whether governments should emphasize openness and cross-border cooperation rather than barriers. That theme lines up with calls for greater international coordination as countries weigh how to regulate powerful AI systems without stifling development.

The unusually high-profile intervention matters because it comes from one of the most influential figures in AI hardware and from a coalition that spans major US technology and defense-linked companies. Even in a brief social media debut, Huang signaled that the industry's policy battle in Washington is becoming just as important as the race to build the next generation of AI.
