CES tech show opens in Las Vegas

The Consumer Electronics Show opens in Las Vegas, with televisions that are getting ever smarter with an eye toward being at the heart of AI-centered lifestyles.

TV titans like LG, Samsung and TCL are packing ever more AI into stunning, huge screens that are inching toward being digital assistants capable of chatting with users and other devices in homes, some with the help of Google or Microsoft.

South Korea-based LG touted the arrival of "Affectionate Intelligence" in which home appliances watch over people -- from tracking how well they sleep to making sure they remember to take an umbrella when rain is in the forecast.
