2) more than 1mm optimus produced and sold in the US
Happy for any counters :)
I'd bet that in 5 years time Optimus total sales are in the 10's of thousands at best, with few to no large scale industrial users (other than self-use by Musk). Customers will be similar to what AgiBot and Unitree currently have - entertainment, hospitality, academic, small scale trials, plus a few Tesla fanboy sales that don't do anything actually productive.
1MM Optimus sold in the US is hilarious too.
Want to make bets on these?
My prediction is Musk will become less and less stable, more and more flamboyant and performative, and less and less effective.
He's already saying he suffers from occasional AI psychosis, and there is no chance that's going to get better on its own.
