In a comment to John Gruber, Apple spokeswoman Jacqueline Roy said:

Siri helps our users find what they need and get things done quickly, and in just the past six months, we’ve made Siri more conversational, introduced new features like type to Siri and product knowledge, and added an integration with ChatGPT. We’ve also been working on a more personalized Siri, giving it more awareness of your personal context, as well as the ability to take action for you within and across your apps. It’s going to take us longer than we thought to deliver on these features and we anticipate rolling them out in the coming year.

I don’t think many people who have paid attention to Apple Intelligence will be shocked by this, but it does underline something I’ve believed for months: shipping the new colorful Siri UI early was a mistake. I love the new UI, but it is tied to the same old, bad Siri. The UI change was a moment for Apple to reset expectations for the technology, and it whiffed on the chance.
