Elon Musk revealed that the new Grok AI/SI training and inference stack is derived from the engineering work behind Starlink. Responding to a SpaceX engineer's note about writing their own headers and calculating time including leap seconds, Musk called it "tight code" and added that "one day, superintelligence will write a better software stack, but that day has not yet come."
