It seems like the safeguards around accuracy alone might be nearly insurmountable. If you ask Siri to send an email that it drafts itself and then messes up, or book some appointment for a Tuesday that it ends up booking for a Thursday, that is a terrible customer and user experience. And Apple would have no defense, other than "the underlying technology hallucinates sometimes" which for many people is not an acceptable explanation for why a feature built into an Apple product works the way that it does. I think the expectation is that whatever gets released for iOS end users will not be plagued by such concerns.
