Amazon announced their latest innovation, Go. Think of Go as a futuristic grocery store. Using sensors, artificial intelligence and computer vision, Amazon is reinventing the shopping experience that we've all grown accustomed to for the last seventy years. If you want to buy an item, just grab it from the shelf, and then Amazon will automatically add the item to your virtual shopping cart. When you walk out of the store, Amazon will magically charge you for that item.

As packages continue to arrive from this year's record-breaking Black Friday weekend, it's no doubt you're seeing Amazon packages complete with front-and-center ads for Amazon's Echo and Dot devices. You may even be one of the reported millions that ordered one that weekend. These are more than just devices -- they are Alexa-enabled and are helping Alexa further integrate into consumers' lives. And Alexa isn't alone: from Alexa to Google Now to Microsoft's Cortana to Apple's Siri, we have a budding class of intelligent agents (IAs) on the rise. In 2015, 45% of US online adults used at least one.

We stand on the precipice of greatness, on the gravel edges of a long path that seems to curve into the sky itself. Someone points to the sky as the sun is rendered to a speck behind a cloud of locusts. The sky turns to black and brown, as packages containing soap, fridge magnets, socks and HDMI cables are dropped from the sky. Amazon Prime Air drone delivery is here and we are saved? Yesterday Jeff Bezos announced the first ever Amazon Prime Air customer delivery.

Amazon announced Wednesday that it had made its first commercial drone delivery. CEO Jeff Bezos revealed in a Tweet that it took 13 minutes from "click to delivery" and that the delivery made to a customer in England is on Amazon's books. Drone deliveries might be in a nascent stage right now, but companies such as Amazon and Domino's have proved with their test deliveries that commercial drone deliveries are a not-so-distant possibility. Drone deliveries take less time than traditional mode of deliveries and seem to be a more convenient way for retailers to make deliveries. Amazon is currently using two of its customers as test subjects, but the company believes that its "Prime Air" service has great potential.

The Mall of America worked with IBM to create a chatbot guide for the nation's largest shopping center. At the Mall of America in a suburb just south of Minneapolis, shoppers walk 1.15 miles just to make their way around a single level of the sprawling shopping destination visited by 40 million people every year. And with multiple floors in total comprising around 5.6 million square feet of total building area--enough to fit nine Yankee Stadiums--some might find it handy to have a digital guide for navigating the nation's largest shopping center. The mall--call MoA by the locals--has partnered with IBM to integrate the company's Watson technology to create a "mobile concierge" that helps shoppers make their way around. Using Watson's conversational API, a holiday-themed chatbot--fittingly named "E.L.F." (short for Experience List Formulator)--helps guests plan a personalized shopping experience based on whatever they're looking for.

Amazon has started its drone delivery trial in Cambridge, UK, the company announced Wednesday. In a tweet, Amazon CEO Jeff Bezos revealed Amazon Prime Air, which promises to deliver packages with small drones in 30 minutes or less after placing an order. The company did not say when the service will be available. "We will deploy when and where we have the regulatory support needed to safely realize our vision," said Amazon. "We're excited about this technology and one day using it to deliver packages to customers around the world in 30 minutes or less."

Why does Amazon's Alexa team need 1000 people? I have stated for quite some time that 50% of all human interaction with computers will be through voice-assisted AI in the next ten years [2]. "What if we didn't need to learn arcane commands? What if you could use the most effective and powerful communication tool ever invented? This tool evolved over millions of years and allows you to express complex ideas in very compact and data dense ways yet can be nuanced to the width of a hair. It is our voice… The last 60 years of computing, humans were adapting to the computer. The next 60 years the computer will adapt to us. It will be our voices that will lead the way; it will be a revolution."
