State Department diplomats have been instructed to stop using the term “artificial intelligence” and instead refer to the technology as “super intelligence,” following President Donald Trump's remarks at the United Nations General Assembly this week.

Michael Drager, deputy assistant secretary of state for the Bureau of International Organization Affairs, sent employees an email shortly after Trump's Sept. 22 U.N. speech directing them to change references to artificial intelligence in official documents and diplomatic positions. The email, obtained by The Associated Press, said the abbreviation “SI” would be used in remarks, positions and press materials going forward.

The Bureau of International Organization Affairs oversees U.S. diplomatic missions to the United Nations and other multilateral organizations around the world. It was not immediately clear whether other State Department bureaus had received similar instructions.

Trump introduced the terminology change during his address to the U.N. General Assembly, arguing that the word “artificial” makes the technology sound fake. He said U.S. government documents would use “super intelligence” instead and encouraged other countries to adopt the terminology.

Trump has also argued that the United States should continue rapidly developing the technology rather than imposing restrictions that could slow the industry. He said artificial intelligence could ultimately have an impact greater than the Industrial Revolution or the internet and has emphasized maintaining the U.S. lead over China in the field.

The new terminology was put into practice at the United Nations on Wednesday, when U.S. representatives used “SI” during a U.N. Security Council meeting focused on the technology. The meeting included technology executives who discussed the rapid development of artificial intelligence and concerns about potential risks.

The term “superintelligence” also has an established meaning in the technology field, generally referring to a form of machine intelligence that surpasses human capabilities. Trump's proposed use of “super intelligence,” however, is intended as a replacement for the broader term “artificial intelligence” in U.S. government communications.

Trump has rejected calls for broad new restrictions on the technology, arguing that the United States should encourage its development while maintaining safeguards. His administration's terminology change now appears to be moving from the president's U.N. remarks into at least some official diplomatic communications.
