Should people know they're talking to an algorithm? After a controversial debut, Google now says yes

Will we demand to know when we're speaking with a bot? Or will we accept that we'll wind up unwittingly conversing with algorithms?

How we respond could have far reaching implications for how humans ultimately treat each other.
