But, they were wrong ... in assuming what they were saying was at all relevant. And they were so sure they knew what they were talking about and that it applied that they dismissed all the ample evidence to the contrary and also dismissed the, they assumed, delusional people pointing out the contradictions. Their initial misunderstanding was understandable given the overloaded terms but their confidence was poorly calibrated to their weakness detecting the misunderstanding.
I’ve seen younger engineers (still very senior and capable but with quick tempers) make this mistake time and time again.
The funny part, to me, is that it all could have been avoided by simply saying something to the effect of “the APIs they call in UTM are Apple’s and there are no hacks or workarounds they can do at the UTM level. Any differences between the hardware are just that.”
The actual thread was wildly inefficient but if it hadn’t gone that way no one would have learned anything, including us!
