Citing The Information, Ars Technica reports mounting trouble in Tesla's pivot to the Optimus humanoid robot.
- The Fremont factory stopped making Model S/X in May 2026, with line workers and engineers reassigned to Optimus
- Some employees resist training the robots that could replace them
- Complex robot hands remain a key technical bottleneck
- Musk called Optimus potentially 'the biggest product ever' on the Q2 2026 earnings call while admitting general-purpose autonomy is 'one of the hardest things to solve' — a track record of unfulfilled predictions looms over the bet.
