I'm just saying that he didn't build the thing himself. He decided to do it and did whatever he does at Tesla, then a lot of smart people worked like crazy to finish by the deadline.

Stretching it a bit (maybe too much): think of going to war. The President gets to decide it, but when you win you don't say "President X won the war". Yet a single soldier is likely as replaceable as a factory worker (before I get more hate, I know they are different but I hope you get my point).
