This is totally right, it will save those people a lot of uncomfortable moments, the same can be say about people who stutter.

I agree mate, this is an example that AI can handle conversations exactly like a human.

Although I would like to see Google Duplex live instead of a recording, but either way eventually that AI will surely manage to have normal conversations every single time.

Do you know the movie Her? I recommend it since it is kinda related to this technology.

Cheers @dysfunctional!
