Do you understand your fiduciary duties? In his prescient 1942 short story, "Runaround," Isaac Azimov proposed a simple set of laws for robots: Yale Law School Professor Jack Balkin has come up with a few more laws for the age of Big Data, when gadgets like Apple's Siri and Amazon's Alexa pose as kindly robot helpers but also collect terabytes of data about your Internet browsing habits, driving patterns and even conversations inside your home. "Think about the basic structure of the problem: We're going to bring into our houses, and use as agents, lots and lots of algorithmic programs," said Balkin, a First Amendment scholar and director of the Information Society Project at Yale Law. "The assumption most people make is they have a relationship with this thing, but what they have is a relationship with the company that makes and sells this thing." And that company may not always have the consumer's best interest in mind.

You can't walk the sprawling floor of the Las Vegas Convention Center without tripping over a speaker, an appliance, or even a robot or two that supports Alexa. Amazon's voice assistant is clearly the darling of CES 2017. This may well be the year you switch from tapping and typing on touchscreens to simply shouting commands. Many platforms, from Apple's Siri and Micosoft's Cortana to Google's Assistant and Samsung's Viv, want to be your conversational partner, but Alexa easily leads the race. The winner will claim a sweet prize.

For cord cutters who want nothing but the best, Nvidia's $200 Shield TV console has always been the box of choice for streaming videos and even games. At CES 2017, the company announced a new-and-improved version that adds in HDR support, refines gaming and entertainment options, and even transforms the Android TV device into a voice-controlled rival of the Amazon Echo. We've already covered all the details revealed during Nvidia's CES 2017 press conference, but I just spent over an hour at Nvidia's suite to learn more about the new Shield TV's every nook and cranny. Here are some initial impressions, and a look at some of the more nitty-gritty improvements that weren't mentioned during the keynote. Before we even get into flashy features like smart-home controls and Google Assistant, the second-gen Shield TV packs worthwhile quality-of-life improvements over its predecessor.

Let's face it: The first digital assistants for the home--Amazon Echo and Google Home--often feel like simple Internet portals with thin veneers of humanity to make them feel more warm and fuzzy. But now Mattel is trying to go beyond that with Aristotle, a personality-driven hardware assistant designed just for kids. Through a partnership with Microsoft (which will lend its Cortana digital assistance technology to the project), the $249 Aristotle straddles the line between a digital nanny for parents and a teaching companion for kids. Though it all might sound a bit hokey, the hardware's pedigree is sound: Aristotle is the brainchild of of Mattel's nabi team, which use to be known as Fubu, the tablet company that Mattel bought in 2016. Aristotle consists of two components: a webcam (think baby monitor) and a cylindrical speaker that chats back and forth with kids.

Amazon doesn't have an official presence at the CES gadget show in Las Vegas but its Alexa voice control software seems to be everywhere. Whirlpool is adding Alexa voice control to its suite of smart-home appliances, including a stove and refrigerator. With that capability, someone can instruct the oven to pre-heat to 400 degrees by speaking a command to an Alexa-enabled device, such as Amazon's Echo speaker. Jason Mathew, senior director of global connected strategy for Whirlpool, says voice is "the most natural way to interact with a product." Other gadgets that include Alexa: Sensory and OnVocal are both launching headphones that incorporate Alexa.

Among the monstrous number of announcements to come out of CES this week a major battle is emerging in the smart home arena. The potential of IoT has never been in question, though the role of smart homes is one which is yet to wow the mass market. The idea is great, but market penetration has been slow. IoT light bulbs, or smart fridges have been around for quite a while, but uptake has not been exceptional. With the introduction of personal assistants as part of the smart home hub, the tide is slowly beginning to turn however.

Four leading car brands have announced deals with three tech giants to add virtual assistants to new cars. Microsoft's Cortana netted two of the deals, the others went to Amazon's Alexa and Google's Assistant. The announcements were made at the CES tech show in Las Vegas. One analyst said there would be a "battle of the giants" over the adoption of virtual assistants in 2017, since they can be built in to a variety of appliances. Nissan and BMW have opted to work with Microsoft to bring Cortana to selected vehicles in the near future.

Nvidia has announced a refresh of its Shield TV streaming and gaming set-top box at CES 2017. The new Nvidia Shield TV delivers better streaming quality, support for Google Assistant as well as better overall performance. The new Nvidia Shield TV now comes with 4K HDR video support. That feature will only be taken advantage of by people who have 4K HDR TVs as well as those subscribed to services that offer that type of streaming quality. Amazon Prime Video and Netflix already have some 4K HDR content, but users will also be able to stream regular 4K content from the likes of YouTube, Vudu and Google Play, as pointed out by Android Authority.

Nvidia Founder, President and CEO Jen-Hsun Huang introduces the Nvidia Spot, a USD 49.95 microphone and speaker that will let owners use Google Assistant anywhere in a home, as he delivers a keynote address at CES 2017 (Photo: Ethan Miller/Getty Images) LAS VEGAS--Nvidia is best known for the high-end computer graphics cards prized by hardcore gamers. If co-founder and CEO Jen-Hsun Huang delivers on his bold vision, more people are likely to recognize Nvidia as the powerhouse behind artificial intelligence in your home and in your vehicle. Clad in his trademark black leather jacket, Huang delivered a high energy opening night keynote address Wednesday night at CES, assuming a prestigious speaking slot that for years was reserved for Microsoft's Bill Gates and later his successor Steve Ballmer. Nvidia (NVDA) is already a star on Wall Street. It is coming off a two-year hot streak, with a particularly sizzling 224% gain in 2016 that made it the top performing stock in the S&P 500.
