I'd be willing to counter bet that. A cloud based AI (what Siri emulates) would be well suited for mobile devices. We are talking first in consumers product though, right? Though I wouldn't want to be testing first/second/third gen AI on anything that is critical.
No, we are talking first as in you will hear about it in some other form before you hear about it on your smartphone. It doesn't exist yet (maybe ever?), hence it is a pretty silly thing to want. Throw it right in with wanting your phone to be a teleportation device and/or transform into a plane for quick travel.
