This is par for the course with a lot of Apple features, it either falls short or comes out late. How many times have they promised some feature or function only to delay it over and over. They talked about incorporating AI for so long yet now people are just downloading Claude or ChatGPT apps to their phone and using that instead. The bonus of having an upgraded Siri is the local context but you can already do a lot of that with Gemini if you use Google. I haven't tested the beta build because I just don't trust it but it sounds like they're well on their way to implementing what they said we would get a while ago. We'll see I guess...
