It’s SXSI. Pronounced sexy
What’s confusing about that? Technoking Elon master planned this
I realise this could be confusing, so to simplify:
SpaceXSI, formerly SpaceXAI, formerly xAI, is a subsidiary of SpaceX, short for Space Exploration Technologies Corp., which focusses on the advancement of Super Intelligence, formerly known as Artificial Intelligence. It used to be owned by xAI Holdings Corp., the owner of X Corp., which owns X, formerly Twitter, but earlier this year, xAI Holdings Corp. was purchased by Space Exploration Technologies Corp., and its subsidiary, xAI, was re-branded to SpaceXAI, and then re-branded to SpaceXSI.
Hopefully that makes sense!
