What you are saying here seems to have a ring of truth to it, but unless you are privy to C-suite and Boardroom discussions, I don't think you can say this with the level of certainty you are ascribing to it. Steve Jobs was not a demi-god and he made his share of errors, as well. That said, he did appear to have a unique genius for user experience related issues. However, any statement about what he would have done with this or that product is completely conjectural. He's not here anymore and we all regret it, but we have to move on to what is, not what might have been.
I'd say you need to go back and re-read my post. The first part of my first sentence was (Bold added for emphasis): 'Whereas SJ
typically had an amazing handle on human factors and "ease of use,"' Last sentence of the 3rd paragraph I wrote "But SJ, based on his record, would have
likely understood them at the first planning meeting and they would have never seen the light of day.
So your inference I presented SJ as a demigod is both false and nothing more than ill-used hyperbole. SJ was human, he did not have a .1000 batting average, but .500 is still Hall of Fame level by heavy margin.
The question I was responding to was why wasn't WatchOS3 OS 1. My answer was that TC doesn't have the skill set SJ had in refining the way products work before release. Instead he beta tests them with the public then makes changes.
What SJ would or would not have done is of course conjecture as you say. Duh. But also as I noted, "based on his record." Conjecture pulled out of thin air, I'll give you. But concluded with circumstantial evidence is enough to convict a person of many crimes. Conjecture can be a useful tool when physical evidence isn't available.
We have 10 years of hard data points on SJ 1.0 products, not to mention a plethora of biographies and an auto-biography, to understand how a SJ's mind worked and how he wanted his 1.0 and succeeding products to function to understand he probably would not have approved WatchOS 1.0 as released, not to mention AW itself with a two function buttons. He would have pushed his staff to make it faster and more intuitive.
And no I don't have privy to the C-suite but Apple released Watch OS1.0 with lots of fanfare. Obviously TC was proud of it as they promoted it for 6 months before release.
