Here’s a small example of why Apple took so long to change Siri to a broader “more” intelligent model.
Back in “classic Siri”, I would say “hey Siri I don’t like this song”, and it would correctly mark it, and also skip it on Apple Music.
Today I said the same to the new Siri.
In choosing the new Siri, they threw away the old Siri that was extremely reliable (to its own detriment and perceived stupidity).
Which one is worse? Both? Hard to say.
