There is some value in producing a lot of solid hardware, but nowhere even close to Tesla's absurd valuation.
I think they are perfectly capable of writing software to drive the robot - if Musk doesn't stick his head in like he did with LIDAR/FSD and impose some stupid requirement that handicaps the product.
But the whole shtick with Optimus is that they aren't writing software. It's supposed to be all LLM training so when you buy your robot you can give it orders like "do the dishes", "clean the gutters", "dig a backyard pool for me", or "build me another Optimus" and you can go off to do whatever while it completes the task.
Elon thinks it would be too expensive to have to write code for every task you might ask one of these to do, they want it to be fully autonomous.
Their engineers aren't behind keyboards typing C++, they're wearing VR headsets and feeding the data to a LLM, although even that is probably too specific for Elon's long term plans. Obviously he doesn't want to have to have people repeat actions hundreds of times before the dumb robots figure it out. Especially for "simple" tasks like serving drinks at press events.
But how would we evaluate "perfectly capable" without evidence, there's just been no evidence they've done anything so far right? Am I missing something? I guess looking closer it was only announced four years ago. But it seems like it's only been smoke and mirrors so far.
