Tesla slips Optimus V3 again, and admits it can't forecast output

On its Q1 call Tesla pushed the Optimus V3 reveal to mid-2026 and confirmed it's tearing out the Fremont Model S/X line to build robots, with production not starting until late July or August. Musk's own framing — output will move "as fast as the least lucky, slowest, dumbest part" of 10,000 — is the most honest thing said about humanoid timelines all year.
