SI On September 29, 2026, President Trump signed Executive Order 14434, “Inaugurating the Era of Super Intelligence.” It was published in the Federal Register on October 2 (91 FR 63129). The order directs the executive branch to use “Super Intelligence” and “SI” in place of “Artificial Intelligence” and “AI” in official correspondence, public communications, websites, reports, policy documents, and other non-statutory documents, to the maximum extent permitted by law.
What changed: the government’s vocabulary for new and ongoing non-statutory communications. On October 13 the White House launched si.gov, and ai.gov redirects there.
What did not change: the underlying law. Section 3(a) defines Super Intelligence and SI as the same technologies already covered by the statutory definition of artificial intelligence at 15 U.S.C. § 9401(3). Section 2(b) says the order does not require rewriting previously issued regulations, Presidential actions, contracts, grants, or other historical documents. It places no obligations or penalties on companies, states, courts, or the public. You can keep saying AI.
What to watch: Section 3(b) gives the Assistant to the President for Science and Technology about 60 days (around November 28, 2026) to submit proposed legislative language for a federal definition of Super Intelligence and SI. That proposal must assess whether the new definition should modify or supersede the existing statutory AI definition, and it may recommend conforming amendments. Until Congress acts, the rename is a style guide for the executive branch, not a new legal category.
Why some experts object: in research, “superintelligence” has long meant a hypothetical system that outperforms humans across most domains. Using Super Intelligence as a government synonym for today’s AI blurs that line, which matters when people debate safety, timelines, and capability claims.
A side effect: .si is Slovenia’s country-code domain. Its registry reported a sharp spike in September registrations after the rename drew attention to the letters SI.
Bottom line for readers: EO 14434 is a terminology policy for the executive branch. The near-term practical question is adoption across agencies and press. The medium-term question is whether the November definition proposal turns a style change into statute.
