Where exactly is the immoral deception coming into play? Duplex may not have announced itself as a bot, but it never announced itself as a human either.
If Google has to have Duplex announce its bot status, should we also have to announce our human status? Otherwise it might be immoral deceptive to allow someone to think we might be a bot.
Does it really matter if your talking to a human or a bot? Especially in the use case of scheduling an appointment. IMHO, if I were answering that call, I personally would prefer talking to Duplex than a real person. The call would be more succinct and to the point. Duplex would have access to the user's calendar to know when an appointment could and could not work instantly
Or, even if you were to dismiss that specific comparison as being silly because there's never been a need to identifying as human before, there are so many others you can make:
If you're a man with a high-pitched voice, you aren't expected to identify as a woman;
If you're a woman with a deep voice, you aren't expected to identify as a man;
You're not expected to state whether the accent you're speaking with is actually your own.
For further actions, you may consider blocking this person and/or reporting abuse
We're a place where coders share, stay up-to-date and grow their careers.
I share similar thoughts.
When a human calls a human, no one declares to the other their 'humanness'.
I like the thought shared in this comment by JG: 9to5google.com/2018/05/10/google-d...
