You know when you go to a restaurant and the menu is like 3 different cuisines, it's 12 pages, and each page has 20+ items?
The Intelligence section of the presentation felt a bit like that.
Generally, I was surprised how lightly Intelligence featured into the keynote: it wasn't a standalone talking point, nothing on the Apple site talks to it directly. It's conspicuous, given that they've dedicated hardware real estate to it ... and the hype cycle.
I go to a restaurant and look at the menu/see a commercial on TV, I can usually order the item now (other than films).
Apple Intelligence - certain feature(s) (can't recall now) are US-only in November, rolling out to other English-speaking countries in December. No idea when non English-speaking countries will get that feature.
Who knows what Apple Intelligence features are in the device on day 1?
Where were you when they were coming up with "when a friend texts a song name to you, remind them they can play it in Apple Music"??!
