Elon Musk on Optimus:

“I remain convinced that Optimus will be the biggest product on earth and humanoid robots in general will be the biggest product on earth. There is no one that is even close to Tesla with respect to a general purpose humanoid robot.

We’ve started like what I’d call early production on our high volume line in Fremont. Now I want to elaborate on this point because and I’ve said this before that the growth of Optimus, it’s an S-curve but the initial part of the S-curve has a shallow slope and is somewhat bumpy because it is such a radically new product.

So the way to think about it is there’s like 10,000 things that have to go right for production of the robot and it’ll move as fast as the slowest least likely of the 10,000. But we do have the vast majority of a million unit production line landed in Fremont right now.”
