I feel like you could have made the same statement about the CRAZY idea of a touchscreen smart phone back in 2007...and then Steve Jobs showed off the iPhone and everyone went...well I guess that does work flawlessly.
Not trying to sound like a fanboy, but simply saying I think Apple's recent track record has proven they're pretty good at releasing products that work flawlessly.
Heck, this could have been the simple reason Siri (now Assistant) was acquired way back in 2008 and is only now coming to light in an iPhone. Jobs may have simply held it back to meet your expectations of him.
