TechCrunch:

While the home crowd cheered enthusiastically at how capable Google had seemingly made its prototype robot caller — with Pichai going on to sketch a grand vision of the AI saving people and businesses time — the episode is worryingly suggestive of a company that views ethics as an after-the-fact consideration.

“Google’s experiments do appear to have been designed to deceive,” agreed Dr Thomas King, a researcher at the Oxford Internet Institute’s Digital Ethics Lab, discussing the Duplex demo. “Because their main hypothesis was ‘can you distinguish this from a real person?’. In this case it’s unclear why their hypothesis was about deception and not the user experience… You don’t necessarily need to deceive someone to give them a better user experience by sounding naturally.”

Many will dismiss these concerns as irrelevant but I personally believe they are crucially important. Thanks to Aaron Miller for the link.
