I really enjoyed the explanation for how they planned on tackling server-enabled AI tasks while making the best possible effort to keep your requests private. Auditable server software that runs on Apple hardware is probably as good as you can get for tasks like that. Even better would be making it OSS.
There was one demo where you could talk to Siri about your mom and it would understand the context because of stuff that she (your mom) had written in one of her emails to you... that's the kind of stuff that I think we all imagined an AI world would look like. I'm really impressed with the vision they described and I think they honestly jumped to the lead of the pack in an important way that hasn't been well considered up until this point.
It's not just the raw AI capabilities from the models themselves, which I think many of us already get the feeling are going to be commoditized at some point in the future, but rather the hardware and system-wide integrations that make use of those models that matters starting today. Obviously how the experience will be when it's available to the public is a different story, but the vision alone was impressive to me. Basically, Apple again understands the UX.
I wish Apple the best of luck and I'm excited to see how their competitors plan on responding. The announcement today I think was actually subtle compared to what the implications are going to be. It's exciting to think that it may make computing easier for older people.
