Musk says SpaceX to change name to ’SpaceXSI’

On Sunday, billionaire entrepreneur Elon Musk announced his intention to change the name of SpaceX to "SpaceXSI," according to a post on the social media platform X. In the post, Musk wrote that there would be "No more AI" and that "SI" was a better term. However, Musk did not specify when the name change would take effect. The suggestion for a new name came after an X user inquired about renaming SpaceX to "SpaceXSI."

Musk confirmed the change in response to the inquiry. This announcement comes in the wake of a recent executive order signed by U.S. President Donald Trump on September 29. The order directs the U.S. government to use "Super Intelligence" and "SI" instead of "Artificial Intelligence" and "AI" in official communications, websites, reports, and policy documents, where permitted by law.

The order defines "Super Intelligence" and "SI" as the technologies encompassed by the existing U.S. statutory definition of artificial intelligence. The White House science and technology adviser has been tasked with proposing legislation within 60 days to establish a federal definition of "Super Intelligence" and "SI." This executive order does not necessitate changes to previously issued regulations, contracts, grants, or other historical documents.
