Myke Hurley blogged a very optimistic take about Siri AI:

I fully understand I may be in that WWDC Glow right now when it comes to Siri AI. I want to preface this before I say what I am about to say, which is that I imagine that after Siri AI ships later in the year, I will not have much need for any of the general-purpose chatbots like Gemini, ChatGPT, Claude, or others.

I don’t see this at all. But everyone is different, and Siri AI should be fairly popular.
