Did you ever use the hockey puck as mouse? Yes that's from the Steve area...
Steve made Apple great but it's an illusion to think a company will grow forever.
Steve was also lucky to have Apple in a time where a lot new stuff was developed. He didn't develop it, he applied it the right way. Things like touch screen and tablets were really new back then.
But today there is not a lot that is new. VR is from the eighties, so is AI.
So I think even today Steve would have troubles to keep Apple growing.
