Elon Musk warned Tesla investors on Thursday that ramping up production of its Optimus humanoid robot and planned robotaxi service will be far slower than many expect, telling the Q1 2026 earnings call that 'it is literally impossible to predict' how quickly the new technologies can be built at scale.
Speaking from California, Musk stressed that initial output of both the Cybercab robotaxi and the company's Optimus line would be 'very slow' this year, with any meaningful revenue impact pushed into 2027.
