The thing / issue at this point is though: how much is Jobs still responsible for Apple's ongoing success? He died 15 years ago, two years after Apple introduced "flat design" (to much criticism at the time but people got used to it). But after his passing, Apple's market value went from ~500 billion to ~4 trillion today, more than an 8-fold multiplication.

I find it hard to believe that his influence was so strong that it had an inertia that lasted for 15 years. Ive left his mark on it for longer.

Apple had a few near death experiences and might not have survived.

One of those early near death experiences might have been Jobs fault (going at the Apple /// and the Mac when, in retrospect, the Apple ][ could have been evolved more aggressively) but he helped bring it back from the brink later on.

Android deserves a lot of credit for the success of iOS in that a zombie mobile OS that doesn't have to be profitable has displaced a competitive mobile OS. A similar kind of fragmentation has bedeviled the Windows (and Linux) PC as well as (from the viewpoint of Windows) distractions such as Azure (good business) and XBOX (bad business.)

Intel deserves a lot of credit for the success of Apple too because for 15 years Intel has had no strategy to translate architectural improvements to experienced performance for client PCs. The way they've gone about SIMD is an absolute disaster, like by the time we can use AVX-512 in mainstream software everybody will have moved on to ARM. Charlie Demerjian would talk your ear off about how the tech press has been uncritical about their hyperscaler/HPC patter, never reminding you that client PCs are still the bread and butter of their business -- pander to the likes of Amazon and they will use any cost savings they get to invest in ARM. It's suicide.

I guess that depends on what you put into the word "success". I dont believe that great design work or great products and high market cap has ever been that related to each other.

With that said I dont think Steve built Apple alone either. And i think they have done some great things after his death as well.
