I'm weirdly happy with Apple taking their time. Seeing AI stuffed into every nook and crevice of various non-Apple apps has made me appreciate apps that use AI tastefully or not at all (counter example: today I tried the LLM built into GitHub's feed page - to describe it as a 'toy' or 'trash' is not overstating how embarrassingly useless it is!). Better not to have junk features, or ones that use AI for AI's sake.
But it seems that the whole Apple Intelligence initiative is impacting iOS 19 [1], which to me makes Apple Intelligence detrimental to the whole OS. Some of the features are nice (smarter Siri, notification summary) others will probably be left to rot like the whole Animoji thing.
