Apple Inc.’s top executive overseeing its Siri virtual assistant told staff that delays to key features have been ugly and embarrassing, and a decision to publicly promote the technology before it was ready made matters worse.

Siri has undergone some improvements thanks to Apple Intelligence, such as a new visual cue for when the assistant is active on the iPhone. When talking to the assistant on an iPhone 15 Pro or later, you can correct yourself in mid-sentence without confusing Siri and you can ask follow-up questions.
