Jason Snell has some good predictions for Apple at Macworld:

I doubt any new-and-improved Siri will be as good as we dream it might be, but I think it’ll be appreciably better than it is today. (And the arrival of a better Siri will unlock Apple’s ability to ship new smart home products, which the company has been itching to do for at least a year.)

I still think Apple’s whole AI approach works against having a universal Siri across devices. Hoping for some surprises in 2026.
