It's funny how "Apple Intelligence" is all over the marketing for these phones; when you place an order it literally says "iPhone 16 Pro Max" and beneath that it says "Apple Intelligence", as if that is the main feature of these phones, possibly even a subtitle of the phone's name itself, and yet the phones won't even launch with Apple Intelligence.
Not that I don't trust Apple to roll out these software updates on time, but the software/hardware schedule they've locked themselves into is producing some awkward results. I can't think of a previous time the release of a phone was centered around a software feature that was coming later. The 4S was in a similar situation, it was centered around Siri, they even claimed the "S" stood for "Siri", but Siri was available at launch. This is different.
It is weird, and it doesn't really have a precedent. It shows the extent to which the AI craze caught Apple by surprise and they had to develop these features on a rushed timeline.
