Duping Duplex
What I want is for my phone's AI to talk to Google's AI (or anybody else's AI, robocaller or phone-script operator) and to not bother me.
Then later, my AI can inform me if there was anything of importance or interest.
Both sides would be happy. The tele-botherer would think it had made a sales call. I would be completely oblivious to it except for the tiny number that would be to my benefit.
