But I do also get the feeling that maybe Musk is just off his rocker and everyone else is copying what he does just in case he actually a genius
Checkout youtube on some chinese factories building like rice cooker and co. They have like 10-50 stops were one person only does like 1-5 things. Putting tape on, screwing something together etc.
I can see it as the last niche were the real big specialised and for purpose build robots are just not economicly
To condense that, i might use a phrase like "blind-buying future option space"
Whether Musk deserves that credit is a moot point. I haven't trusted a thing he's said for years, and studying him for revealed intent can't get past "clown on drugs" without violating occam's razor.
