Roller skates, beds, autonomous flying cars, smart clothing, robots, aromatherapy, flexible video screens, wireless everything, drones, artificial intelligence (AI), toys, analytics, smart cities, and anything tech were alive and well at CES 2018 with over 2.75 million square feet of exhibits and 1,000-plus presenters. Other surprises included a flood on opening day of the show— after 190 days of no rain in Las Vegas — and a two-hour power outage at the convention center on day two.
