> It being perfect isn't the issue; it's that random people on the internet who are just learning about this assume Apple's engineers haven't already thought about everything (and more) mentioned in this thread.

Given how many bugs there are in macOS and how long they have remained there, I (who have been writing iOS apps from the release of the first retina iPod touch until AI got good) functionally agree with such people; at best, I think Apple's engineers haven't actually solved everything (and more) mentioned in this thread, even if every one of these things may have come up in discussions and even reached an official backlog or task list or similar.
