Elon Musk shared a Grok Bot summary of SpaceX CFO Bret Johnsen's interview: Johnsen came from semiconductors (Qualcomm, Broadcom, MindSpeed) and joined SpaceX after one factory visit convinced him to move back to LA. He now oversees 700 launches from Mission Control across a 40-building campus. With the January xAI acquisition plus X, Cursor and Colossus, complexity has multiplied in 1-2 years — and AI is now the biggest business at SpaceX, bringing him full circle back to chips.
