Siri is really quite dumb. I am confident that a 7B model would be able to provide better responses in over 90% of user queries. I can't even get Siri to reliably set a timer.
If trained on an iPhone API + documentation and given a little web access it would blow absolutely everything out of the water.
If they can already create -basic- Python/Swift/JS/rust apps that sets timers, save things, create lists, how's that too dumb for being a Siri replacement? They just have to give it access to an iPhone/Web Api like ChatGPT's code analysis tool.
So if you ask it "hey siri do this, this and this", it will create a script, then run it on the internal API, or fetch an article then work on that etc.
I know it's still logically "dumb" but i'm not trying to play game theoretical scenarios with my phone or do logic tests or advanced math (yet).
But yeah "hey siri transfer all of my funds to eric", or "hey siri group all of my photos where i'm nude and send them to jack" are new almost sci fi vectors.
