From the time Apple bought Siri, it hasn't even delivered on the promises of the company it bought as of yet. It's been such a lackluster product. I wouldn't count them out, but it doesn't even feel like they are in.
Apple really dropped the ball when it comes to Siri. For years I watched WWDC thinking "surely they'll update siri this year" and they still haven't given it a significant update.
If you'd have told me 10 years ago that Apple would wait this long to update siri I would have been like no way, that's crazy.
Maybe Apple is not that close and Siri will be really far behind for a while. I just wouldn't count them out yet.
