Front and center at CES was the battle between virtual assistants. Aaron Emigh, chief executive of Brilliant, which makes smart home products that work with Alexa, Google Assistant and Siri, said it was critical for virtual assistants to work together, not against one another, because the smart home was already too complex, with products like light switches, thermostats and cameras coming from different brands.

Smarter cars with features like built-in voice assistants to help people use maps, play music of get a sports update without taking their eyes off the road are available now.
Matt Strauss, a Comcast executive, was especially bullish about the year ahead. He said just about everything announced at CES required an Internet connection, so that's the last thing that people would cut off.
