Why .si

In September 2026 the US government officially renamed AI “Super Intelligence — SI”. Elon Musk (“No more AI. SI.”) and Nvidia’s Jensen Huang adopted it within days, and .si registrations jumped 2,199%. .si is the only address on the internet that spells SI — and every great word exists only once.
