I get the sterile feeling part but how did you make the jump to "political correctness"?
It’s good in many ways, but also hard to ignore just how obvious that effort is once you realise it’s there. That’s true for all presentations, including the dev talks at WWDC.
It is hard for me to push aside the impression that nowadays the speakers - regardless their background - are entirely chosen for optical reasons. My only favourite moment in a recent big presentation was the M1 chip part with Srouji. That guy is not made for the camera but man he lives hardware with every fibre of his soul.
Everything else is "politically correct" according to this segment.
