This is brilliant!
Can I set up Duplex to answer scam callers and string them along for hours in the background while still leaving my phone available to use for "normal" conversations?
I guess the downside of that would be if the scammers are also using Duplex to make the call.
Then it could be another case where the two AI's start making up their own language to where we wouldn't know if they were plotting against us.
