  • Elon Musk shared a new progress update video on Tesla's humanoid robot called Optimus. 
  • It shows the robot doing squats and picking up an egg and says it's 30% faster than the old model. 
  • Its X account says it can perform "unsafe" and "boring" tasks, but it's unclear how it'll be used. 

Is Tesla's humanoid robot going to be a personal trainer?
