The Apple Silicon transition also involves software (Rosetta), which works absurdly well given the complexity of what it's doing.
Exactly my point: the same company wrote Rosetta and the new Settings. Clearly not the same level of talent and commitment in those two teams.
But the software side? There seems to be a massive variance in both ability, and giving-a-shit across the software orgs, and no leadership filter on the output of these disparate groups.
Perhaps they have the opposite of the resting-on-laurels problem: a smattering of very senior people who are talented and care about the product/users, and a wide base of careerists who aren't very good and just want the money and the CV, users be damned.
