Oh no, you got me.
And since I've been caught talking nonsense let me explain how I (as an outsider) got these crazy ideas:
I overestimated complexity involved in creating smarts behind it, Siri and Bixby mislead me. Glad to know that google assistant and duplex are two absolutely different products and duplex is not a new feature on the same (often confused by the same words commands) foundation.
And I thought that due to all the complexity to create this original assistant/AI it would be high-level product where even in messed up corporation environments no duplicate efforts would slip through (we all know how dysfunctional big companies are, or maybe just because it's Google (they have multiple chat apps) that's the way how they approach all the initiatives). Of course I was wrong and they have multiple assistants being created. It's just a matter of having one more team tasked with it.
Those Apple and Samsung, looks like they're not even trying!
And about submission itself - it was an absolutely real call to suspecting nothing regular person, who just happened to talk in that particular way, similar to how I try to provide all the context when doing web searches (but funny thing is that it doesn't even matter - demo was not to make a call to real restaurant, it was just showing functionality being developed, they may have even put someone on scene to take a call, but decided to insist that demo call was absolutely regular one instead)
Anyway, I hope everybody is happy and not all worked up anymore, I was wrong on the internet, was put on my place and accepted that.
peace
