Correct, Apple changing the UI before changing the backend might be one of the more stupid things I’ve ever seen.
The messiest launch ever. The renewed UI makes it easy to assume that the LLM-backed Siri is already here but just isn't much better than the old one. A marketing disaster.
Yes, although before full "LLM Siri," Apple promised an "enhanced" Siri with contextual understanding in iOS 18. The clock is ticking though—WWDC will be here before you know it.
