Yeah I wonder about Federighi. He doesn't seem to catch much criticism from the Apple pundits—I assume because he's one of the few SVPs that seems like a real human in interviews and videos and not a stilted robot like the rest of them. But Apple's software, and macOS in particular, seems to be rotting from the inside out. Changes ship and everyone says "boy this is a step backwards, I hope they iterate quickly" and then it sits, almost entirely unchanged, for years on end. e.g. new Settings in macOS, Stage Manager on the iPad.
With how much the hardware team has been knocking it out of the park since the ARM transition it's really starting to feel like the software is the weak link. This rumoured massive redesign this year has me feeling very anxious.
