I don’t think it does. This isn’t a hypothetical Siri v2 with some upgrades; it’s a hypothetical LLM chatbot speaking with Siri’s voice. I recall one of the first demonstrations of Bing’s ability was someone asking it to book him a concert where he wouldn’t need a jacket. It searched the web for concert locations, searched the web weather information, picked a location that fit the constraint and gave the booking link for that specific ticket. If you imagine an Apple LLM that has local rather than web search, it seems obvious that this exact ability that LLMs have to follow complicated requests and “figure things out” would be perfectly suited to reading your emails and figuring out which restaurant you mean. With ApplePay integration it could also go ahead and book for you.
Certainly not the only place, but you’re very right that it does house a large population of commenters like me who enjoy the “sport” of “being correct on the internet”.
And yet the parent makes a very specific (and correct) comment, that this wont be Siri with some upgrades, but Siri in the name only, with a totally different architecture.
Whereas yours and your sibling comment are just irrelevant meta-comments.
