CES 2018: voice-controlled showers, non-compliant robots and smart toilets

The annual trend-setting tech extravaganza that is CES International in Las Vegas is drawing to a close, having suffered through torrential rain, blackouts and a few uncooperative robots. And it's clear that your voice is more important than ever. CES 2018 rammed home that big technology thinks voice is the next major evolution in computing.
