It’s not Elon musk that’s doing the work, it’s the actual workers. Sure, maybe Musk has the capital and audacity to try these things, but that does not mean he’s the one putting in the skilled work required for this
No, it's like saying the owners of aerospace engineering companies don't deserve credit for the designs the aerospace engineers working at them produce.
It's not a statement I agree 100% with, but it's definitely the case these days that individual workers are not given enough credit. It's also the case that the owners, executives, and other high-ranking management types are given far too much credit for successes and far too little blame for the failures.
Without any of the founders and Elon Musk there would be no Tesla Model Y. Doubt there are very many engineers about whom the same could be said. In totality the individual contributors are more important but Elon Musk is the person without whom the enterprise is dead on arrival.
