CES 2019: Alexa vs. Google, foldable TVs and 5G to take center stage in Las Vegas

This year's Consumer Electronics Show is bringing the latest in tech including self-driving suitcases and motorcycles. Every year, the Consumer Electronics Show kicks off the new year with a smorgasbord of new gadgets that may -- or may not -- ever see the light of day, gee-whiz new prototypes that do, indeed, wow us, and lots of talk about the next big thing in tech that's right around the corner. This year, the show floor chatter will be all about 5G broadband and artificial intelligence, and how they will change our lives as know it. The faster 5G internet signals will provide the backbone needed for autonomous self-driving cars and smart cities, for improved traffic flow and other services. AI will take the promise of the still burgeoning Smart Home, and using our voices to command Alexa and Google to turn on and off the lights and tell us the weather.
