Steve Job didn't "understand design", but he understood what a good design can do for his product, and knew what he liked. So he put the design team as the highest in Apple, and had every other team answer to the constraints of the design. It worked. Musk may not "understand AI", but he understands what AI can be made to do, and he knows what he likes. Which frankly, for the boss, is more important than understanding the code. And, he knows how to find and hire the right talent, how to excite them, and how to keep them. And how to ship. IMO it is unfair to say "his company did it" especially when his rivals in each of those industries failed where he succeeded (including OpenAI, which he gets at least some credit for). He understands enough of what he needs to about both AI and business to make it work.
