Elon Musk posted one word. Grok. He was quoting SpaceX's vice president of launch, Kiko Dontchev, on a job most people will never think about. An inspector slides a tiny camera down a tube inside a rocket part and searches for anything that does not belong there, a metal shaving or a loose fastener. They call it foreign object debris. One missed piece can destroy an engine. Dontchev described what happens next. "We'll have an inspector go in and borescope a tube, and we find that humans are about 94 percent perfect at finding a piece of it. Grok analyzing the same video is 99.9 percent perfect." The technician still holds the camera. Grok never looks away. Dontchev has spent 16 years at SpaceX. He said the acceleration in engineering this year is unlike anything he has seen in all that time. Work that used to take hours or days now takes seconds or minutes. They have automated visual inspections of Starlink terminals as well, with a similar jump in accuracy. If you only meet AI in a chat window, this can sound like a factory footnote, easy to scroll past. Sit with the numbers. Dontchev talked about a future of thousands of flights a year. At that cadence, leaving a few percent of debris undetected is a mountain of hidden risk. 99.9 percent is a different kind of machine. The obvious place to show off Grok at a rocket company would have been a launch broadcast. They pointed it at the inside of a tube. That is how Elon Musk uses intelligence. He puts it where a mistake is expensive. Dontchev also described what SpaceX has become. Yes, a rocket company. Fundamentally, an infrastructure company, on the ground and in low Earth orbit, soon on the Moon and eventually on Mars. He believes they would have reached the Moon and Mars anyway. Then he added what AI changes: "We're going to get there so much faster." The destination was set long ago. Super intelligence is how the work on the factory floor starts moving at the speed of that plan, and Grok is already watching the footage that used to depend on a tired pair of eyes.
