I absolutely disagree, it's very poor quality. The best example I've gathered incidentally is "what's this song" regressing between versions to replying with an admonishment to turn off the music or podcast, no matter how quiet it is. Then the one time I've tried to set a reminder, Siri confirmed it was set, and it never actually worked.

Considering how many years it's been around, these sorts of inexplicable failures are really inexcusable. Sure, I understand nobody tests their software anymore, but "predictable" is not the term I would use to describe Siri.
