I think they just started implementing it. If they were already deeply involved in their AI they would instruct or give tools to developers at WWDC24.TBH; I'm shocked that a massive company such as Apple with so much talent in there cant ship Apple Intelligence at launch. I feel like there is something in terms of politics/approvals going behind the scenes thats impacting it and not purely just need more time to test it.
Nothing there… just the announcement about what might possibly come.
By the time it’s ready in 2025 I’m sure competition have their second implementation ready with all the bells and whistles Apple promises and more.
