Apple Intelligence-powered Siri is very late, to say the least. That’s largely been because Apple has struggled to keep up with developing their own AI models. I’d say its largely played out this way because Apple has been hesitant to wanting to spend a lot of money, not to mention that Apple’s stance on privacy makes it hard to train a model – Apple just doesn’t have much data.
Nonetheless though, this delay actually comes with a bit of upside.
